12 1 Introduction 1 Introduction 1.1 What is Pointfuse? Pointfuse quickly and accurately converts point clouds (typically from LIDAR scanners and photogrammetry) into intelligent mesh models, with selectable surfaces, and including RGB and intensity textures. It builds models from all or part of a point cloud, or from multiple point clouds. You can crop a model further, and generate 2D plans/sections, and orthographic images. Intelligent mesh models consist of polylines and polygons as well as surfaces (both plane and irregular surface meshes). They have a far smaller memory footprint than the original point data, so need less computing power to visualize and manipulate. Furthermore, they contain richer geometrical properties than point clouds, which means you can select and classify objects such as pipes and walls. Pointfuse is a seamless and integral part of BIM workflows, and is especially useful in infrastructure, asset management, and health and safety projects. You can export 2D images and 3D models for further processing, typically CAD tools. Pointfuse is available for physical Windows PCs Trying and Buying Pointfuse You can get Pointfuse from Try the software for free. The trial version includes all the features of the licensed version, except that you are limited to three exports of mesh models to other formats. The trial version has buttons to buy Pointfuse. See Installing Pointfuse on page 90 for details License Expiry When your license expires, Pointfuse will be unlicensed until you buy or renew a Pointfuse license. Without a license, functionality is limited to viewing models generated by a licensed copy of Pointfuse Feature Summary The features of Pointfuse include: Automatically build mesh models from point clouds, creating an intelligent model of surfaces and edges. Textures can include: RGB and intensity. Import and view point clouds from airborne, mobile and terrestrial LIDAR scanners, as well as from photogrammetry. Source files can be in formats including DP, E57, FLS, FWS, LAS, LAZ, PTS, PTX and XYZ. Import and view externally built mesh models. Change camera view and projection for optimal viewing. Page 1

13 1 Introduction Visualize point clouds and mesh models in a variety of ways. Point clouds can be colored by RGB, Intensity or Elevation, and for mesh models you can select textures, and use smoothing and antialiasing. Crop point clouds before converting to a mesh model. Crop, convert and combine multiple point clouds into a single intelligent mesh model. Edit mesh models: crop, and create plans and multiple sections at specified intervals. Classify features: select and group geometries so you can separate elements, such as pipes or walls. Export all, or selected parts of models, direct to Autodesk BIM 360. Save mesh models, including crops, and plans/sections, and export some or all of the surfaces, for use in CAD software. The supported formats are: DAE (COLLADA), DXF (Drawing Exchange Format), IFC (Industry Foundation Classes), NWC (Navisworks), OBJ (Wavefront), STL (StereoLithography), SKP (SketchUp), or FBX (Filmbox). You can include a texture in exports to OBJ, DAE or FBX. Create scaled orthographic images from point clouds and mesh models. 1.2 About this User Guide This assumes familiarity with common Windows conventions, such as mouse control, menus, toolbars etc. You do not need prior experience of working with point data or mesh models. There are three main sections: Quick Start, from page 4 A brief but essential overview of the Pointfuse interface and core functionality, with links to the sections with further details. This is relevant for all versions of Pointfuse. Main Body, from page 23 Comprehensive, task-oriented instructions for using all the features of Pointfuse. Appendixes, from page 74 Detailed reference information, including installation instructions (page 90) and toolbar and menu items. The Glossary is at the back Formatting Conventions Ordinary bold is used for emphasis. The names of fields and items you click (toolbar buttons and menu items) are in this bold font. Italics and angle brackets are used for variable elements, e.g. <point cloud name>. Notes are in boxes like this, with a pen symbol. Important links to sections where you will find further details are in boxes like this, with an arrow. Other links are in ordinary paragraphs. Page 2

15 2 Quick Start 2 Quick Start This section summarizes typical workflows, the interface, and how to convert point data to an intelligent mesh model comprising structured surfaces and edges. More advanced features, such as editing tools (cropping, and creating ortho images, and plans/sections), are in the more detailed sections that start with section 3, on page Simple Workflows You can create a mesh model from a point cloud in a few simple steps, accepting defaults: Start Pointfuse Load a point cloud Generate Surfaces Mesh model created Figure 1 Simplest Pointfuse Workflow See Building Intelligent Mesh Models from Point Data on page 12 for an overview of loading a point cloud into a Pointfuse project and generating a mesh model. Start Pointfuse If you are uncertain what resolution will work best for your point data, use cropping (page 55) to create a small point cloud and then generate surfaces for that, using different settings. Then compare the results to decide which resolution to use to generate a model of the original point cloud. Load a point cloud and display it in viewport Crop to create a new, small point cloud Generate Surfaces, selecting a Processing Profile Generate Surfaces, selecting a different Processing Profile Sample mesh model created Sample mesh model created Compare models and note best resolution Select original point cloud and generate model with chosen Processing Profile Final mesh model created Figure 2 Workflow for Quickly Comparing Resolutions Page 4

16 2 Quick Start 2.2 Full Workflow This illustrates the many ways you can use Pointfuse to work with your point data and the mesh models you generate. Create New Project Create scan folder(s) containing point cloud(s) This illustrates the key stages of a typical Pointfuse workflow. Optionally display point cloud Crop (another) point cloud? NO YES Remove unwanted points See subsequent pages for further details, including: New Project Wizard on page 24, specifically Figure 13 on page 24. Project Explorer Window on page 7.

17 2 Quick Start 2.3 The Interface The interface has common Windows components, including: a menu bar, right click/context menus, a toolbar, dockable windows, status bar, plus a central tabbed viewport for viewing the data. It also uses the concepts of projects containing a hierarchy of related files, and of selecting and grouping surfaces for classification, so they can be added or removed from view without affecting the data itself. You can rearrange (and close) the windows and toolbar; the layout will be retained between sessions. To revert to the default layout, select Options > Windows > Reset Layout, and to reset all display options, including those on the Options > Preferences dialog, select Options > Preferences > Restore Defaults. The screenshot shows the default arrangement of windows (Project Explorer, Properties, and Scene Tree), either side of the viewport, which is displaying the file listed in bold in the Project Explorer: Figure 4 The User Interface Menus, Toolbar and Shortcuts This is the Quick Start section: see Toolbar and Menu Functions on page 74, Menu Functions on page 76, and Keyboard Shortcuts on page 79 for more details. Functions on menus and the toolbar are greyed out when they are not relevant. Page 6

18 2 Quick Start There are context menus when you right click in the Project Explorer, viewport and toolbar area. Project Explorer context menus vary according to the item selected (project, scan, file). See Project Explorer Context Menus on page 77. Where an option has a keyboard shortcut, it is listed on the menu, e.g. New Ctrl+N, and also in Keyboard Shortcuts on page 79. Toolbar buttons are also on a menu, but not all menu items have a corresponding toolbar button Project Explorer Window This is the Quick Start section: see Projects and Files on page 23 for more details. The Project Explorer shows a hierarchy of folders and files, with expandable branches and context menus. It is also where you select what to display in the viewport. The top level is the project. You can only open one project at a time. The next level contains work items called scan folders. New scans are added to the bottom, above the Ortho Images folder. Drag and drop to change the sequence. Each scan folder contains child folders: Point Clouds Vector Models (mesh models) Plans / Sections They cannot be renamed in Pointfuse. The child folders are for individual files of the relevant type: Point Clouds Vector Models (mesh models) Plans / Sections When these files are displayed in the current viewport tab, they are listed in bold. Images that are not editable in Pointfuse are listed in folders at the bottom: Ortho Images Snapshots Figure 5 Project in the Project Explorer The same icons are used to indicate the contents of each viewport tab. Page 7

19 2 Quick Start You can also drag and drop files from one scan folder to another; they will automatically be put in the appropriate child folder (e.g. point clouds in a Point Clouds folder). The Project Explorer is a way of viewing and working with files in Pointfuse. You should only work with such files (especially adding, deleting and renaming) in Pointfuse. See Views and Properties on page 23 for details Tabbed Viewport The viewport displays the data in tabs (or views). When you open a file, it is initially displayed so that the full extent is visible and centered. Each tab can contain either 3D data (point clouds and/or mesh models) or a single 2D file (plan/section, ortho image or snapshot). Each tab displays an icon indicating the file type, plus the file name. If a tab is displaying multiple 3D files, up to two icons are shown beside the name of the file most recently added to the tab. For example: From left to right, tabs containing: a point cloud, a mesh model, a mixture of point clouds and mesh models, a snapshot, a plan/section, and an ortho image. Figure 6 Tab Titles: Icon and File Name You can change what and how things are displayed in each tab. See Changing How the Model Looks on page 30 and Changing How You Move Around the 3D Model on page Displaying a File Only one project can be open at a time, but each project can contain multiple scan folders, child folders and files, and you can view multiple 3Dfiles in each tab of the viewport, e.g. combining point data and mesh models. Furthermore, each tab can have different settings (background color, camera etc). You do not need to display a point cloud in the viewport to convert it to a mesh model. 1. Open a file or its parent project, by selecting File > Open or File > Recent Projects. If you select a Pointfuse project, it will be listed in the Project Explorer. Right click one of its files in the Project Explorer and then select either Add to New Tab or Add to Existing Tab to display it in the viewport. Alternatively, double click it, which will Add to New tab. If you select a point cloud or mesh model, the New Project wizard is displayed. Amend or accept the default Name, Directory and Description, and whether to create a new project folder and whether to import the file into it. (See Creating a Project on page 12.) When you click Finish, the project will be listed in the Project Explorer and the file displayed in a new tab. 2. The file displayed in the viewport has its name in the Project Explorer shown in bold. Page 8

20 2 Quick Start Removing and Deleting Files from View To remove a file from display, just close the tab. To close all tabs, but keep the project open, select View > Close All Tabs. To remove one of several files in the current tab, right click it in the Project Explorer and select Remove from View, or select another file and then select Replace View. (You can only replace a 3D file with another 3D file.) To delete files from the project, select them in the Project Explorer, right click the selection and click Delete. To delete folders, with all their contents, delete the parent scan folder. This ensures the integrity of the project structure Scene Tree Window The Scene Tree window displays details of what is displayed in the current viewport tab not necessarily what is selected in the Project Explorer. If you have multiple files open in the same viewport tab (for example, a point cloud and the model you built from it), you can toggle the display on and off for each. If you select and classify surfaces into groups, you can see and manage a hierarchy of model elements here, and toggle display on and off for each. When exporting, you can choose which elements to include in the export. See Selecting Surfaces for Classification on page 47. Figure 7 Scene Tree where only Ticked Items are Displayed Properties Window This is the Quick Start section: see Views and Properties on page 23 and Project and File Properties on page 84 for screenshots and details. The Properties window displays details of the item currently selected in the Project Explorer not necessarily what is in the viewport, OR of selected surfaces: Page 9

21 2 Quick Start Project properties Values are the Name, Description, File Name (path), and Directory. You can double click Name and type a new one. (See Name and File Name on page 23.) File properties Values depend on the file type: point cloud, mesh (vector) model, snapshot etc. You can change Name and Description: double click in the field and type a new one. (See Name and File Name on page 23.) For point clouds with intensity values, you can adjust the intensity, as described in Intensity Bounds on page 32. Geometry properties When you select surfaces for classification, you see properties of what is selected, including vertex bounds and counts. See Selecting Surfaces for Classification on page Edit Tools This is the Quick Start section: see Editing Point Clouds and Mesh Models on page 55 for more details. Pointfuse has tools for editing point clouds and mesh (vector) models in X, Y and Z dimensions. The tools are: Cropping, Plans / Sections, and Ortho Images Arranging Dockable Windows You can move, resize or close the windows and the toolbar. By default, the windows are pinned to the left or right of the workspace, as in Figure 4 on page 6. To switch between docked and undocked (floating), double-click the window s title bar. To resize a docked window, drag the edges; to resize a floating one, drag the corners. To move a window (or toolbar), drag the title bar. Windows can be grouped, occupying a single window space, with tabs at the bottom. To separate tabbed windows, drag the title bar of one of them to a new position. To close a window, click the X icon at the top right corner, and to close a window or toolbar, right click in the menu/toolbar area and untick it. The edit tools windows are only visible when you use an editing tool (e.g. cropping). See Editing Point Clouds and Mesh Models on page 55. Each time you open Pointfuse, the layout will be as it was when you closed Pointfuse. Use Options > Windows to Reset Layout to the default and select individual windows Status Bar The status bar along the bottom display progress and status messages. Page 10

22 2 Quick Start Other Preferences This is the Quick Start section: see Defining Preferences and Defaults on page 80 for more details. Define defaults for many things, using Options > Preferences. These include background color, how point clouds are displayed, the preferred texture for rendering mesh models, and the location of cache files. Use Options > Preferences > Restore Defaults to revert to factory defaults for these preferences. There are also Processing Profiles that apply when converting point data to mesh models. Page 11

23 2 Quick Start 2.4 Building Intelligent Mesh Models from Point Data To build a mesh (vector) model, you must load a point cloud into a Pointfuse project: Select the New Project wizard from the menu, as below. The wizard has a second page where you can add more point clouds to the project. You can also Add Scan (point cloud) to a currently open project. See Add Scan on page Creating a Project This is the Quick Start section. For further details, see: Simple Workflows on page 4 and Full Pointfuse Workflow on page 5. Projects and Files on page 23. New Project Wizard on page 24. Pointfuse has a project-based structure, with a hierarchy of folders and files. Scan folders are the key concept: folders at the top level within the project, containing all the files relating to each point dataset: the point clouds themselves, mesh models, crops, and plans/sections. Ortho images and snapshots are part of the project, but not in a scan folder. To create a new project, you need at least one file containing point data, such as a LAS or LAZ file (see Supported File Types on page 86). 1. Select Create New Project from the startup screen or select File > New to open the first page of the New Project wizard: Figure 8 New Project Wizard, Page 1 2. Type a Project Name, overwriting the default. 3. Enter the path for the Project Folder, or click the Browse button to open a dialog to navigate to an existing folder or create a new one. Page 12

24 2 Quick Start 4. Leave the Create Project Folder field ticked so that Pointfuse creates a folder for the project; it will have the same name as the project. For example: Project files will be in: K:\New Church 2 project\new Church 2 However, if Create Project Folder is not ticked, they will be in K:\New Church 2 project 5. Optionally enter a Project Description. This will be shown in the Properties window whenever you select the project in the Project Explorer. 6. Click Next to open the second page of the wizard. The new project is in the panel on the right; it does not yet contain any folders or files: Figure 9 New Project Wizard, Page 2 Page 13

25 2 Quick Start 7. Navigate the file list and select one or more point clouds to import. Figure 10 New Project Wizard, Page 2, After Adding Point Data 8. If you select more than one point cloud, choose how you want your project structured. See Figure 13 Project Structure: Single and Multiple Point Clouds per Scan Folder on page 24. Click the single chevron to add selected point clouds to a single Point Clouds folder. Click the double chevron or drag and drop selected files onto the project folder. This creates multiple scan folders: one folder for each point cloud. To convert multiple point clouds into a single mesh model, the point clouds must be in the same folder. 9. To rename a Scan folder or point cloud in the project, select it and press F2. You can remove or delete point clouds and folders (and their child folders) by right clicking. 10. To change the Input Units, double click in the field, and select from the dropdown. 11. Choose whether to leave the Import Data field ticked. If you untick it, point clouds are not copied to the new location, although they are listed in the Project Explorer (actually just a pointer to the source). This avoids duplication and saves disk space, but if they are moved, renamed or deleted in the source location, you will no longer be able to access them in this Pointfuse project. Page 14

26 2 Quick Start 12. Click Finish to create and save the project. A simple project structure will be shown in the Project Explorer, but all the folders will be empty except the Point Clouds ones: Figure 11 New Project Folders in Project Explorer To create new folders and add point clouds to the project later; see Add Scan and Add Data on page 26. Page 15

27 2 Quick Start Generating Surfaces (Making a Mesh Model) This is the Quick Start section. For further details, see: Simple Workflows on page 4 and Full Pointfuse Workflow on page 5. Generating Surfaces (Build Mesh Model) on page 27. Generate Surfaces converts point data to a mesh (vector) model. This section describes the simplest case: building a single model from a single point cloud. See Figure 1 Simplest Pointfuse Workflow on page Open or create a project that contains the point cloud. You do not need to display the point cloud in the viewport to convert it, unless you want to crop it first. 2. In the Project Explorer, select the scan folder or point cloud you want to convert. 3. Click Generate Surfaces or select Edit > Generate Surfaces or press the shortcut, Z. Figure 12 The Generate Surfaces Dialog, with Processing Options 4. Ensure the selected Scan Group is the one containing the point data to convert. Page 16

28 2 Quick Start 5. If the folder contains more than one point cloud, by default all are ticked and will be combined into a single mesh model. 6. You can amend the Output Name. 7. Decide whether to Generate Textures (e.g. color the model surfaces using RGB or intensity). 8. Select a Processing Profile, which determines the Resolution and Tolerances used to create the model. The names of the default profiles (Terrestrial High Quality, for example) are for guidance. The values best suited to converting your particular point cloud may differ. See Processing Profiles on page Click OK to start the process. 10. When all the tasks are all 100% complete: The status bar will display Ready (with large files, there may be a slight pause first). In the Project Explorer, there will be a new file in the Vector Models folder. 11. You can now display the mesh (vector) model in the viewport. Page 17

29 2 Quick Start 2.5 Viewing and Moving Around the Model There are three aspects: how the viewport looks, how the model looks, and how you move around, as summarized below (and repeated on page 45). See Changing How You Move Around the 3D Model on page 41 for full details. Perspective Projection Orbital Camera Intuitive navigation with regular mouse. Drag left mouse button Double left click Mouse wheel 3Dconnexion mouse Cursor keys R Rotate camera about orbit center. Make click point the orbit center, at viewport center. Rotation unchanged. Roll to zoom in/out. Hold and drag to pan model. Zoom in/out, and rotate on X and Y axes. Because the orbit center is fixed, it is not ideal for fly-through. Rotate camera about orbit center. Reset to original orbit, orientation and zoom. Free Floating Camera Ideal for fly-though with 3D mouse. Drag left mouse button Double left click Mouse wheel 3Dconnexion mouse Cursor keys R Rotate camera orientation. No effect. Intuitive, multidimensional, free movement through the model. Pan up/down and left/right, zoom in/out and rotate on X and Y axes. Zoom camera in/out and sideways. Reset to original orbit, orientation and zoom. Orthographic Projection (Also known as Parallel Projection) Useful for editing (crop etc). Drag left mouse button Double left click Rotate camera about orbit center. Make click point the orbit center, at viewport center. Rotation unchanged Drag left mouse button Double left click Pan model left/right and up/down. No effect. Mouse wheel Roll to zoom in/out.

Reset to original orbit and orientation. Zoom unchanged. Table 1 Projection, Camera and Mouse Interaction Page 18

30 2 Quick Start Viewport Settings This is the Quick Start section: see Viewport Settings on page 37 for more details. Settings can be different for each viewport tab. Settings you can change by right clicking in the viewport (or using the main menus) include: The background color, and if it is solid or a gradient. The grid, when viewing 3D data. (It is always off for 2D plans/sections.) Remove all models from the viewport tab (they will still be listed in Project Explorer). Full screen. Press Esc or Ctrl+Return to revert to normal mode Colors, Antialiasing and Smoothing Point Cloud Shading Method This is the Quick Start section: see Shading Method: Elevation, Intensity and RGB on page 31 for more details, including screenshots of results. Point clouds can be rendered in three ways, selected from View > Point Cloud, or the toolbar, or, to set defaults, Options > Preferences > Visualization: Single Color The point cloud is displayed with all points a single color. Elevation The point cloud is colored according to elevation, where blue is the lowest and red the highest. This is especially helpful when viewing undulating landscapes that lack the clear outlines of buildings. RGB Red, Green and Blue are used (if present in the data), to display the point cloud in color, for a more realistic effect. Intensity Displays the points using the point cloud s intensity values (if present in the data). Page 19

31 2 Quick Start Vector Model Coloring Method This is the Quick Start section: see Mesh (Vector) Model Settings on page 33 for more details, including screenshots of results. Mesh (vector) model surfaces can be colored in several ways, selected from View > Vector Model, or the toolbar, or, to set defaults, Options > Preferences > Visualization: Solid Color Surfaces are displayed in the single color chosen for the Surfaces (change this in the Properties window). RGB Texture Red, Green and Blue are used (if present in the source point cloud), to display the model in realistic color. Intensity Texture Displays the model using intensity values (if present in the source point cloud) Antialiasing and Smoothing Use View > Antialiasing and its smoothing options in combination with View > Point Cloud > Dynamic Point Size to reduce jagged and sharp features of 3D models. Smoothing options usually work better if antialiasing is on. Antialiasing is also essential when editing (cropping and making plans/sections). Page 20

32 2 Quick Start Camera and Projection Controls This is the Quick Start section: see Changing How You Move Around the 3D Model on page 41 and Table 1 on page 18 for more details. The camera controls (Orbital or Free Floating), in conjunction with the projection settings (Perspective or Orthographic), give you power and flexibility to view and move around the models. A 3Dconnexion mouse provides even more. However, familiarity with the variety of permutations and functionality takes a little practice: 1. Start by displaying a point cloud or mesh model. It should default to Orbital camera (left) and Perspective projection (right), and using a regular (not 3D) mouse: 2. Use the mouse and/or cursor keys to move around (see Table 5 on page 45). 3. From the dropdown on the button, switch from Orbital to Free Floating camera. 4. Enable the 3D mouse (Options menu) and use that to move around the model. If you get disoriented inside a model or move the model out of sight: Use Reset View to display the model in the center of the viewport, at the default zoom level and orientation for the current camera and projection combination. In Orbital (fixed) camera mode, double click where you want the orbit center to be Mouse Controls This is the Quick Start section: see Invert Mouse (Regular) on page 43, Enable 3Dconnexion Mouse on page 43 and Table 1 on page 18 for more details. Pointfuse is designed to work with two mice: You need a regular (not 3D) mouse for moving the pointer and clicking selections, and you may also find it useful for big movements (e.g. zooming large distances). A 3Dconnexion mouse is ideal for fine-tuning movement and for fly-throughs. Mouse behavior is affected by camera and projection settings, e.g. whether the mouse appears to move the model or the camera. Page 21

33 2 Quick Start 2.6 Creating Crops, Plans/Sections and Ortho Images This is the Quick Start section: see Editing Point Clouds and Mesh Models on page 55 for more details. Pointfuse has tools to edit 3D data: Crop point clouds and mesh (vector) models Create 2D plans and sections of mesh (vector) models, including creating multiple sections at specified intervals Create 2D scaled orthographic images of one or all faces of a point cloud or mesh model There is also a Measurement Tool (see page 38) and a Snapshot tool (see page 39). 2.7 Exporting Mesh Models This is the Quick Start section: see Export on page 70. You can export some or all of the surfaces of a mesh model directly into Autodesk BIM 360 or to file formats you can import use in other CAD software. The supported formats are: DAE (Collada) DXF (Drawing Exchange Format) FBX (Filmbox) IFC (Industry Foundation Classes) NWC (Navisworks) OBJ (Wavefront) SKP (SketchUp) STL (StereoLithography) You can include a texture in exports to OBJ, DAE or FBX. You can export 2D plans/sections to DXF and STL. 2.8 Save, Close and Exit Select File > Close to close the current project but leave Pointfuse open. Select File > Exit to close the current project and exit Pointfuse. Opening a new project will also close the current one. Page 22

34 3 Projects and Files 3 Projects and Files This is the first of the detailed sections. It recaps some of what was in the preceding Quick Start section, but in greater detail. Before reading this section, please read the Quick Start section, particularly: Project Explorer Window on page Views and Properties The Project Explorer is just a view of the point clouds, mesh (vector) models and other project files; they are stored differently on your computer. This is why you should only work with Pointfuse files in Pointfuse itself (especially when adding, deleting and renaming). For example: The folder structure is different (e.g. in Windows Explorer, all point clouds in a project are in a single folder). Pointfuse uses icons to distinguish different types of file (see Figure 5 on page 7). Files you rename in Pointfuse will be listed by their original name in Windows Explorer. If you unticked Import Data into Project Folder when you created the project, those files will not be in any project folders in Windows Explorer; what you see in the Pointfuse Project Explorer is a pointer to the source file, rather than the actual file. Exports to DAE, DXF, IFC, OBJ, STL, or SKP formats, which cannot be opened in Pointfuse, are listed in Windows Explorer, but not in the Pointfuse Project Explorer Name and File Name The concept of a view of project files is more obvious when the Name and File Name in the Pointfuse Properties window are different: The Name is the name displayed in Pointfuse. This is the name of the source file, unless you have renamed it in Pointfuse, in which case the Pointfuse name will be displayed. The File Name is the file s original name (what you would see in Windows Explorer). The File Name includes the path; if you left Import Data into Project Folder field ticked when you created the project, that will be the project folder, but if you unticked it, the path will be the source folder. See Project and File Properties on page 84 for a list of all Properties fields and Supported File Types on page Renaming To change the display name of the project, scan folder or file, either right click on the item in the Project Explorer and select Rename, or left click on it and press F2. Page 23

35 3 Projects and Files 3.2 Project Structure New Project Wizard The Quick Start section has screenshots of the wizard (see Creating a Project on page 12). This section describes more complex scenarios, including importing multiple point clouds. 1. Select File > New, which opens the first page of the New Project wizard. 2. Type a Project Name (overwriting the default New Project). 3. Enter the path for the Project Folder, or click the Browse button to open a dialog to navigate to an existing folder or create a new one. 4. If you leave Create Project Folder ticked, Pointfuse creates a folder for the project that has the same name as the project. If you untick it, folders and files will be in the location shown in the Project Folder field. 5. Optionally enter a Project Description to display in the Properties window when you select the project. 6. Click Next, which opens the second page of the New Project wizard. 7. Build up a project structure by selecting point clouds to the project. Select one or more point clouds on the left and click a chevron button to add to the project. Multiple Folders Click the double chevron or drag and drop to create multiple scan folders for selected point clouds: one folder for each point cloud (each with the same name as its point cloud), creating a project like this: Single Folder Click the single chevron to add all selected point clouds to a single Point Clouds folder, beneath the currently selected scan folder, creating a project like this: This is essential if you want to generate a single mesh (vector) model from multiple point clouds. Figure 13 Project Structure: Single and Multiple Point Clouds per Scan Folder 8. Click Finish to create and save the project, close the dialog and see it in the Project Explorer. Page 24

36 3 Projects and Files Changing Project Structure The structure you create with the New Project wizard is not final. Create new scan folders and add point clouds to the project (see Add Scan and Add Data on page 26). Press F2 to rename a selected folder or file. (See Name and File Name on page 23.) Drag and drop scan folders and individual files to change the sequence. You can only move files into other folders of the right type a point cloud into a point cloud folder, for example. Ortho Images and Snapshots are 2D files, so are created in Ortho Images and Snapshots folders respectively; they are not be in a subfolder of a scan folder Importing Point Clouds to a Project Add point clouds to an existing project in two ways: create a new scan folder or add to an existing one. You cannot import mesh (vector) models Add Scan Use this to create a new scan folder in the current project and add point data to it. 1. Click Add Scan, or, in the Project Explorer, right click the project folder and select Add Scan. Figure 14 Add Scan Dialog 2. In the dialog, specify a Name for the new scan folder. 3. Navigate to the point cloud data, select the files you want, and either drag to the panel on the right, or click the chevron. Page 25

37 3 Projects and Files 9. To change the Units, double click in the field, and select from the dropdown. 4. Click OK to add the data and close the dialog. 5. A new scan folder will be created at the bottom of the Project Explorer. It will contain the default folders of Point Clouds (containing the point clouds), Vector Models (containing mesh models), and Plans/Sections. 6. Save the project: File > Save or Ctrl+S Add Data Use this option to add point data or mesh (vector) models generated in Pointfuse to an existing scan folder: 1. In the Project Explorer, right click on a scan folder and select Add Data. 2. In the dialog, navigate to the data (point clouds or Pointfuse mesh files PVF). 3. Select the files you want and click Open. 4. The point clouds will be added to the Point Clouds folder of the selected scan folder. 5. Save the project: File > Save or Ctrl+S. Page 26

38 4 Generating Surfaces (Build Mesh Model) 4 Generating Surfaces (Build Mesh Model) You build an intelligent mesh (vector) model from one or more point clouds. The resulting model is added to the list in the Project Explorer, in a Vector Model folder. You can then display the mesh (vector) model in the viewport, edit and export it. You do not need to display point clouds in the viewport to convert them. 1. Open or create a project that contains the point cloud. (See Creating a Project on page 12.) 2. In the Project Explorer, select the scan folder or point cloud you want to convert. 3. Click Generate Surfaces or select Edit > Generate Surfaces, or press the shortcut key, Z. This opens the Generate Surfaces dialog, illustrated in Figure 12 on page Ensure the Scan Group containing the point data to convert is selected. 5. If the Scan Group contains multiple point clouds, all are selected by default, to combine in a single mesh model. 6. Choose an Output Name. 7. Choose a Processing Profile, which determines the resolution and tolerances of the mesh model. Either select an existing processing profile from the dropdown list or click the Browse button to define a new processing profile: If you choose a custom processing profile that you created previously, you can amend the Name, Resolution, and Tolerances by double clicking in the Value column and typing a new value. If you choose one of the profiles supplied with Pointfuse (Terrestrial, Mobile or Airborne), the values are not editable. See Processing Profiles on page Choose whether to Generate Textures for the model. 9. Click OK to start the process. The status bar will show progress. 10. When the process is complete: The status bar will display Ready (with large files, there may be a slight pause first). In the Project Explorer, there will be a new mesh model in the Vector Models folder (that folder will have been created if it did not already exist). Display the model in a new tab in the viewport by double clicking on it in the Project Explorer. You can export the model. See Export on page 70. Page 27

39 4 Generating Surfaces (Build Mesh Model) 4.1 Processing Profiles A processing profile specifies the resolution and tolerances for converting point data to mesh models. Pointfuse has default profiles for the presumed level of detail for point clouds sourced from Terrestrial, Mobile or Airborne technology, and for high, normal, and low quality of each. The names of the default profiles are for guidance. The values best suited to converting your particular point data may differ. To compare them, crop to get a smaller portion of the point data (see page 61) and quickly do multiple conversions, using different profiles. Resolution: The smaller the resolution value, the greater the detail, but the more time, memory and disk space may be used. There is no direct correlation between resolution and processing time: higher resolution models are sometimes quicker to generate than lower resolution ones. Typically in the range m. Planar Fitting Tolerance: The depth of field, typically one third of the resolution, in the range to 0.3m. Surface Angle Tolerance: The threshold, in degrees, for creating an edge and new surface. Typically 18 degrees. If working with curved surfaces like pipes, try increasing to around 22 degrees. Generate Textures Select this if you want the mesh model to include textures (RGB or intensity) from the source point data. This is the only value you can change for default profiles Creating Custom Processing Profiles Custom profiles are not limited to the projects you created it for, but are available in all projects on your computer. Options > Preferences 1. Select the Options > Preferences dialog. Select the Processing Profiles tab. Generate Surfaces Click Generate Surfaces or click Edit > Generate Surfaces. 2. You see a dialog that includes a dropdown list of processing profiles. 3. Select New. Select the Browse button. 4. You see the New Processing Profile dialog: Page 28

40 4 Generating Surfaces (Build Mesh Model) Options > Preferences Generate Surfaces 5. Use the dropdown to select an existing profile to use as the basis for the new one. It can be one of those supplied with Pointfuse, or a custom one you created previously. 6. Type a Name and click OK. The previous tab or dialog is redisplayed. 7. Amend Name, Resolution and Tolerances by double clicking in the Value column and either typing a new value, or using the chevrons to increment or decrement. Choose whether this profile will Generate Textures by default. 8. Click Apply to save changes and OK to close the dialog. Click OK to save changes, close the dialog and start generating surfaces Deleting Custom Processing Profiles Delete custom processing profiles from the Preferences dialog. You cannot delete the default profiles. Profiles relate to your computer, rather than the current project. Before deleting a profile, be certain you will not need it in another project. 1. Select the Options > Preferences dialog, Processing Profiles tab. 2. Use the dropdown to select an existing custom processing profile. 3. Click Delete. You will not be prompted for confirmation and the profile will be deleted regardless of whether you then press OK, Cancel or Apply on the main Processing tab. Page 29

41 5 Changing How the Model Looks 5 Changing How the Model Looks Combine the effects of several tools to customize how the model looks in terms of colors of points, lines and surfaces, and how they are rendered. The ideal combination depends in part on the specific dataset. This section summarizes the features, but as they affect each other, experiment to explore what suits your data and purpose. 5.1 Point Cloud Settings Change these settings from the toolbar, context menu or View menu to apply to all point clouds displayed in the current viewport tab except for Intensity Bounds, which can be adjusted for each point cloud (see page 32). To change the defaults, use Options > Preferences > Visualization Defaults Dynamic Point Size The points of a point cloud can be displayed at a fixed size, regardless of how far away they are, which means that when you zoom in, they look small and spread out. Alternatively, if you enable Dynamic Point Size, points will scale up as you zoom in. This creates a more solid effect that is particularly realistic when the shading method is RGB. The effect of this setting can be adjusted with smoothing: see Point Clouds - Smoothing and Antialiasing on page 36. Dynamic Point Size OFF, zoomed in (Point Smoothing ON and Antialiasing OFF) Dynamic Point Size ON, zoomed in (Point Smoothing ON and Antialiasing OFF) Figure 15 Effects of Dynamic Point Size To enable or disable this by default and define the starting point size, use Options > Preferences and select the General tab. See Visualization Defaults Tab on page 82. To toggle Dynamic Point Size for the current tab, either select View > Point Cloud > Dynamic Point Size or right click in the viewport and select Dynamic Point Size. Page 30

42 5 Changing How the Model Looks Shading Method: Elevation, Intensity and RGB A point cloud is displayed with one of three shading methods, although whether all three options are effective depends on whether the relevant values are in the source data: To change the default setting for subsequently opened tabs, use Options > Preferences and select the Visualization Defaults tab. See Visualization Defaults Tab on page 82. To change the setting for the current tab, click the relevant toolbar button, or select from the View > Point Cloud menu or the right click menu in the viewport. Option Description Example Elevation RGB The point cloud is colored according to elevation, where blue is the lowest and red the highest. This is useful for natural landscapes that lack the clear outlines of buildings. Crop the point cloud (see page 61) to remove peripheral data, so the full color gradient is applied to the area of interest. Red, Green and Blue are used (if present in the data), to display the point cloud in color. Intensity Displays the points using intensity values (if present in the data). The range of shading can be adjusted in the Properties window. See Intensity Bounds, below, and Properties of Point Data and Mesh (Vector) Data on page 84. Table 2 Point Cloud Shading Options Page 31

43 5 Changing How the Model Looks Intensity Bounds For point clouds that include intensity data, you can dynamically adjust contrast using slider controls in the Properties window. 1. Display one or more point clouds in the viewport. If you display multiple point clouds in a viewport tab, you adjust them independently. This means you can have them displayed in a similar range (instead of one dark and one light). 2. If the point data is colored by Elevation or RGB, click Intensity on the toolbar. 3. In the Project Explorer, make sure the point cloud you want to adjust is selected. 4. In the Properties window (see Properties of Point Data and Mesh (Vector) Data on page 84), note the intensity fields: 5. Click in the Value column to display the sliders used to adjust intensity: Intensity Data Bounds Display-only field, showing the minimum and maximum intensity values in the point data. Intensity Output Bounds The range of intensity values used to display the selected point cloud. By default, the full range is used every time you display a point cloud: Maximum Contrast (default) Black, with Minimum Contrast Figure 16 Adjusting Intensity Bounds White, with Minimum Contrast The upper slider controls the minimum value (black). Move it right to narrow the range of intensity values, towards the white end of the scale, and thus the range in which the lower slider can move. The lower slider controls the maximum value (white). Move it left to increase the black and reduce the white. Reset moves the slider to the minimum or maximum value in the data. Page 32

44 5 Changing How the Model Looks 5.2 Mesh (Vector) Model Settings Change these settings from the toolbar, context menu or View menu to apply to all mesh models displayed in the current viewport tab. To change the defaults, use Options > Preferences > Visualization Defaults Color by Textures Textures are created automatically when you generate surfaces in Pointfuse - if the relevant values are in the source point cloud. Option Description Example RGB Red, Green and Blue are used (if present in the source point cloud), to display the mesh model in realistic color similar to an RGB point cloud, but with the much smaller file size of a mesh model. Intensity Displays the mesh model using intensity values (if present in the source point cloud). Solid Color Displays a mesh model s surfaces in a single solid color. Table 3 Mesh Model Texture Options If you export a mesh model to DAE or OBJ, you can include a texture. See Export on page 70. Page 33

45 5 Changing How the Model Looks Highlight Surface You can highlight a surface, to see its extent or when classifying surfaces: press Ctrl+Click on it. To remove the highlight, press Esc or Ctrl+Click on the background. See Selecting Surfaces for Classification on page 47. This is also useful when measuring part of a complex model. See Measuring a Model on page Setting the Highlight Color To change the highlight color for the current tab, either right click in the viewport or select the View menu. Click Change Highlight Color. To change the default for subsequently opened tabs, select Options > Preferences > Visualization Defaults > Highlight Color Specular Highlights Specular highlights are the effect of a light source on surfaces (mesh models): light is reflected more strongly in one direction. They emphasize the surface s shape and position in relation to the light source. You cannot move the light source, but as you move the model, the pool of light lands in different places. Switching on specular highlighting shows these reflected highlights in the mesh model (but has no effect on point clouds). To toggle highlights for the current session, right click in the viewport and select Specular Highlights. To change the default for subsequently opened tabs, select Options > Preferences and select the Visualization Defaults tab. See Visualization Defaults Tab on page 82. How the highlights look depends on the data and the zoom level. Page 34

46 5 Changing How the Model Looks 5.3 Antialiasing and Smoothing Antialiasing needs to be enabled when editing so that the selection cuboid is transparent (see Editing Point Clouds and Mesh Models on page 55). Antialiasing and smoothing are adjustments that, in combination with dynamic point size, can reduce jagged and sharp features of 3D models (point clouds and mesh models): Item Effect Applies to Antialiasing Smoothing Point Smoothing Color blending that uses intermediate shades of grey or color (depending whether the data is color or not) to blend neighboring pixels, for a subtler effect, with less contrast. Changes which pixels are colored, and makes small changes to the size and horizontal alignment at the edges of points, lines and polygons, e.g. to make points rounder. Points are rendered round (instead of square), which can make them look slightly bigger when zoomed out and create a more realistic and solid effect. Point Clouds, Mesh Models. Point Clouds. Line Smoothing Lines look thicker. Mesh Models. Polygon Smoothing Surface edges look smoother. Mesh Models. Table 4 Antialiasing and Smoothing To change the defaults for subsequently opened tabs, use Options > Preferences and select the General tab. See Visualization Defaults Tab on page 82. To toggle these features for the current session, either select View and then tick or untick the feature, or right click in the viewport, select Antialiasing, and then tick or untick the feature. Page 35

47 5 Changing How the Model Looks Mesh (Vector) Models - Smoothing and Antialiasing If coloring a mesh model by RGB texture (see Color by Textures on page 33), the best effect may be to switch off both line smoothing and antialiasing. However, if you switch line smoothing on, also switch antialiasing on to soften the effect. Line Smoothing OFF Antialiasing OFF Line Smoothing ON Antialiasing OFF Line Smoothing ON Antialiasing On Figure 17 Smoothing and Antialiasing Mesh Models Point Clouds - Smoothing and Antialiasing For point clouds, the most suitable combination of smoothing and antialiasing depends on whether the point size is fixed or dynamic as well as the dataset. If you are zooming into points, you generally want Dynamic Point Size switched on (see page 30) Point Smoothing OFF Antialiasing OFF Point Smoothing ON Antialiasing OFF Point Smoothing ON Antialiasing ON The lightening is not as marked when you zoom in. Figure 18 Smoothing and Antialiasing Point Clouds Page 36

48 5 Changing How the Model Looks 5.4 Viewport Settings These can be set for each tab of the viewport, or as global defaults Change the Background Color To change the background color for the current tab, either right click in the viewport or select the View menu. Click Background Color. To change the default for subsequently opened tabs, select Options > Preferences and select the Visualization tab. See Visualization Defaults Tab on page Change the Grid Having the ground plane grid displayed gives a sense of scale, perspective, and direction. However, sometimes, it is useful to switch it off to examine details, especially if they are near the ground. As well as switching it on and off, you can define the color of gridlines. To toggle the grid on and off for the current tab, click Grid, or select View > Grid, or right click in the viewport and select Grid, or use the shortcut key G. To change the default colors for subsequently opened tabs, select Options > Preferences and select the Visualization tab. See Visualization Defaults Tab on page 82. To change settings in the current tab, select View > Grid > Settings. The grid is automatically switched off when viewing 2D plans/sections and snapshots Full Screen Making the viewport full screen is useful for demonstrations. It hides the dockable windows, toolbar, title bar, menus and status bar, giving more space for viewing the data. Use the shortcut Ctrl+Return to switch between Full Screen and normal display. Alternatively, use View > Full Screen to switch from normal to Full Screen and Esc to exit Full Screen mode. 5.5 Invert Mouse and 3Dconnexion Mouse The Options menu has two mouse-related options that apply to the current tab: Invert Mouse and Enable 3D Mouse. The Options > Preferences > General dialog has the same options, but if set there, they will be defaults for future tabs. These are integral to the way the cameras and projection settings interact, so are explained in that section. See Invert Mouse (Regular) on page 43 and Enable 3Dconnexion Mouse on page 43. Page 37

49 5 Changing How the Model Looks 5.6 Measuring a Model Ortho images show a scale (see Figure 38 on page 69), but you can directly measure mesh models (and point clouds), edit the measurements, add them up, and export them to a CSV file. 1. Click Measurement Tool. 2. In the dialog, click Start and select what to measure. For a clearer view and to ensure you click on the correct surface, Ctrl+Click on a surface (see Highlight Surface on page 34). Line: Single click a start and end point. Then the tool stops measuring, but the dialog remains open. Lines: Single click a start and end point for the first line. A third click starts measuring the next line, and so on, until you click Stop. Polyline: Each single click is a part of one polyline, until you click Stop. Polygon: Each single click is a part of one polygon, but it adds an additional line at the end which snaps back to the first point. To finish defining and measuring the polygon, click Stop. Figure 19 Measuring a Model and the Measurement Tool Dialog Page 38

50 5 Changing How the Model Looks Measurement lines are color coded on the model: Red = previously measured, and listed in dialog Yellow = previously measured, and currently selected on model and in dialog Blue with no end point = currently measuring 3. The measurements and X, Y and Z positions of each point are displayed in the dialog, as in the example in Figure 19, above. 4. Repeat for multiple measurements. 5. Select a polyline or polygon to see and select the Edit dropdown: Continue: Allows you to append more points to a polyline or polygon. Insert Before: Inserts any new measurements before the selected line in the polyline or polygon. Insert After: Inserts any new measurements after the selected line in the polyline or polygon. Click on a node and drag it. The measurements in the dialog are recalculated. 6. To remove an individual line or polygon, select it in the viewport or the dialog and click Remove. To remove all the lines and polygons, click Clear. 7. Click Export Measurements to create a CSV file containing all the values listed in the Measurement Tool dialog. 5.7 Snapshot Tool Use this to create a high-resolution 2D image of the 3D point cloud or mesh model, as currently displayed in the viewport. The snapshot shows the same view/orientation as in viewport. If you have classified surfaces (see Selecting Surfaces for Classification on page 47), only those currently displayed in the viewport are included in the snapshot. Specular highlights and textures are included if used. The toolbar, menus, and windows are not included. Each snapshot is added to the Project s Snapshots folder. Double click it to open it in a new tab, or right click and select Open Externally, to open in the default application for that file type. 1. Click Snapshot on the toolbar or select Edit > Snapshot.

52 6 Changing How You Move Around the 3D Model 6 Changing How You Move Around the 3D Model The camera controls (Orbital or Free Floating), in conjunction with the projection settings (Perspective or Orthographic), give you a great deal of power and flexibility to view and move around the 3D models, using mice and cursor keys. (They are not relevant, and therefore disabled, when viewing 2D plans, sections, ortho images and snapshots.) The permutations can be a little disorienting at first, so you need to understand how they work individually and in combination. See Table 5 Projection, Camera and Mouse Interaction on page 45 for a summary. If you get disoriented inside a model or move the model out of sight, use Reset (or View > Reset View, or shortcut R) to display the model in the center of the viewport, at the zoom level and orientation that is the default for the current camera and projection combination. 6.1 Camera: Orbital or Free Floating You change position and orientation by clicking and dragging the regular mouse, twisting and tilting the 3D mouse, and using cursor keys. These are for 3D models, so disabled when viewing 2D plans/sections, ortho images and snapshots. There are two types of camera, selected from the dropdown on the Navigation button : Orbital Orbits a fixed point in 3D space (the orbit center). By default, this is the model s center. The orientation adjusts so that however you move the model, the orbit center stays in the center of the viewport. Change the orbit center by double clicking on a different place on the model. Usually best for regular (not 3D) mouse. Free Floating The camera s orientation is altered by clicking and dragging a regular mouse, just moving a 3D mouse, or using the cursor keys. Usually best for 3D mouse fly-though (with Perspective projection). Table 5 Projection, Camera and Mouse Interaction on page 45 lists how the different cameras work with regular and 3D mice. Page 41

53 6 Changing How You Move Around the 3D Model 6.2 Projection: Perspective or Orthographic There are two types of projection, selected from the dropdown on the Projection button : These are for 3D models, so are disabled when viewing 2D plans/sections, ortho images and snapshots. Perspective Elements that are the same size in reality are scaled in the viewport so that those nearer the front look larger than those further away. This is a realistic look for 3D data, but it can be tricky to make direct comparisons of the size of different parts of the model. Figure 21 Perspective Projection of Model Orthographic Elements that are the same size in reality look the same size in the viewport, even if the model is positioned so that some are nearer the viewer than others. This makes it easier to compare the size of different parts of a 3D model, although it does not mimic how things look in real life. You may also find it easier when editing (cropping etc). Orthographic projection is sometimes known as Parallel projection. Figure 22 Orthographic Projection of Model By definition, ortho images use Orthographic projection. If the viewport is displaying files in Perspective projection, you will notice the difference. See Orthographic Images on page 67. Note that the difference in projection is shown in the grid (if displayed) as well as the model. Page 42

54 6 Changing How You Move Around the 3D Model 6.3 View Position Select from the dropdown to reset the view to a specific face: 6.4 Mouse: Invert and 3D Your interaction with the model and cameras is affected by the mouse or mice (and the projection - see Table 5 Projection, Camera and Mouse Interaction on page 45). More specifically, you can invert regular mouse actions, and can have a 3D mouse in addition to a regular one Invert Mouse (Regular) Dragging the mouse in the viewport rotates either the camera or the model about the orbit point. The direction of movement depends on whether the mouse is moving the model or the camera. Either is valid, but they have opposite results. Switch between the two using Options > Invert Mouse for this session, or Options > Preferences > General to remember between sessions. It will only affect a regular (not 3D) mouse: When Invert Mouse is not ticked, the model moves in the same direction as the mouse. When Invert Mouse is ticked, the model moves in the opposite direction to the mouse. This applies whether the camera itself is set to Orbital or Free Floating, and whether the projection is Perspective or Orthographic, although the feel of the control is slightly different with each permutation Enable 3Dconnexion Mouse Although you can view and manipulate the model with a regular (not 3D) mouse or an equivalent such as a touchpad, Pointfuse is designed to work with a 3Dconnexion mouse as well. It does not replace a regular mouse, which you need for actions that involve moving and clicking the pointer (menu and toolbar selections etc). With a 3D mouse, you can simultaneously pan, zoom and rotate. This is particularly useful for delicate movements and for doing a smooth, virtual fly-through of a model, with the camera in Free Floating mode and the model in Perspective projection (see Table 5 Projection, Camera and Mouse Interaction on page 45). Page 43

55 6 Changing How You Move Around the 3D Model For big movements (e.g. zooming large distances), you may prefer the regular mouse. The 3D mouse behavior is fixed, regardless of the mouse s own settings or Pointfuse s Invert Mouse setting. To enable (or disable) it, use Options > Enable 3D Mouse for this session, or Options > Preferences > General to remember between sessions Capabilities of 3Dconnexion Mouse The 3D mouse controls views of the model (in addition to a regular mouse). Instead of moving the whole mouse to move the pointer, you move the cap (like a short joystick), as if it is the camera. A 3D mouse lets you move in up to six ways, depending on camera and projection: Pan up/down Pan left/right Zoom in/out Rotate on Y axis (twist to spin left/right) Rotate on X axis (tilt forwards/backwards) Rotate on Z axis (roll) not implemented in Pointfuse When the 3D mouse is enabled, use that and the regular mouse, along with different camera and projection settings, to get the precise combination to suit what you are doing. If you are new to using a 3D mouse, you will probably find it helpful to set its tracking speed to be slow (see the documentation for your 3D mouse) and to remember the keyboard shortcut R to Reset View (also on the toolbar and menus). Page 44

56 6 Changing How You Move Around the 3D Model 6.5 Interaction of Projection, Camera and Mouse The two camera modes react differently to a regular mouse, 3Dconnexion mouse and cursor keys. Furthermore, camera and mouse behavior depend on the projection mode. The best way to understand these permutations is to experiment with them, but in summary: Perspective Projection Orbital Camera Intuitive navigation with regular mouse. Drag left mouse button Double left click Mouse wheel 3Dconnexion mouse Cursor keys R Rotate camera about orbit center. Make click point the orbit center, at viewport center. Rotation unchanged. Roll to zoom in/out. Hold and drag to pan model. Zoom in/out, and rotate on X and Y axes. Because the orbit center is fixed, it is not ideal for fly-through. Rotate camera about orbit center. Reset to original orbit, orientation and zoom. Free Floating Camera Ideal for fly-though with 3D mouse. Drag left mouse button Double left click Mouse wheel 3Dconnexion mouse Cursor keys R Rotate camera orientation. No effect. Intuitive, multi-dimensional, free movement through the model. Pan up/down and left/right, zoom in/out and rotate on X and Y axes. Zoom camera in/out and sideways. Reset to original orbit, orientation and zoom. Orthographic Projection Useful for editing (crop etc). Drag left mouse button Rotate camera about orbit center. Drag left mouse button Pan model left/right and up/down. (Also known as Parallel Projection) Double left click Mouse wheel Make click point the orbit center, at viewport center. Rotation unchanged Roll to zoom in/out. Double left click Mouse wheel No effect. Roll to zoom in/out. 3Dconnexion mouse Rotate on X and Y axes. No fly through. 3Dconnexion mouse Pan up/down, left/right, and rotate X and Y axes. No fly through and may get distortion if you rotate more than about 180. Cursor keys Rotate camera about orbit center. Cursor keys R Reset to original orbit and orientation. Zoom unchanged. R Reset to original orbit and orientation. Zoom unchanged. Table 5 Projection, Camera and Mouse Interaction Page 45

57 6 Changing How You Move Around the 3D Model 6.6 Reset View and Restore Defaults If you get disoriented: View > Reset View, or shortcut R, or click Reset. This only resets the position of the model to the defaults set in Options > Preferences > Visualization. It does not change window positions or colors. Options > Preferences > Restore Defaults Resets dockable windows, grid, and colors etc (items on Options > Preferences) to defaults. Use View Position to reset the view to a specific face. Page 46

58 7 Selecting Surfaces for Classification 7 Selecting Surfaces for Classification Select and group surfaces to include or exclude them from view and from exports, without changing the mesh model itself. For example, you can classify surfaces that make up the floor, or a group of pipes, with subfolders for each type of pipe. When you select and classify a group of surfaces, you choose to move or merge them into a geometry group: Move Surfaces will be grouped in a folder, but still individually selectable in the viewport. Merge Selecting any part of the merged surfaces in the viewport will select them all. If your Merge includes surfaces from two different models, some of the surfaces will be moved to the folder of the surfaces they are merged with. You view and manage the groups from the context menu of the viewport and also from the Scene Tree window at the bottom right. See Scene Tree Window on page 9. You can change the Surface Color, Line Color, and Line Thickness for each group of surfaces in the Properties window, without losing RGB or intensity data. This makes it easy to identify particular features. You can select and permanently delete features such as floors or people. This is a useful alternative to cropping (see Cropping on page 61). You can select and classify multiple times so your model comprises multiple geometry groups. Page 47

59 7 Selecting Surfaces for Classification 7.1 Example Workflow for Classifying Surfaces See sections after this for details of individual steps shown in this diagram. Optional: create folder structure in Scene Tree Choose selection mode: Append, Replace, or Remove Select surfaces Right click and select Move Geometries Move Move as group of separate surfaces or Merge? Merge Right click and select Merge Geometries Do you want to create a folder? Yes Select parent folder and Add Group No Select folder and click Add Geometry Select geometry group and click OK Optionally color-code geometry groups Do you want to classify more surfaces? Yes No Save project Figure 23 Workflow for Classifying Surfaces Page 48

60 7 Selecting Surfaces for Classification 7.2 Creating Geometry Groups in the Scene Tree This stage is optional. You can select and classify surfaces, creating and amending a hierarchy of folders as you go (see page 52). To create the structure before you start selecting: 1. In the Scene Tree, right click on what will be the parent folder: 2. Select Add New Group. Groups (folders) can contain other groups as well as geometry nodes (selected surfaces). 3. A new folder is added, titled New Group Node. To rename it, select it and press F2. 4. Repeat to create other folders. 5. To create a named location for selected surface geometries, right click on what will be the parent folder and select Add New Geometry Group. 6. A new geometry group is added, titled New Geometry Node. To rename it, select it and press F2. 7. If you create just one folder and one geometry group, without changing the default names: 8. Repeat to create other geometry groups. 9. Save the new scene tree before you start selecting surfaces to move and merge. Page 49

61 7 Selecting Surfaces for Classification 7.3 Selecting Surfaces 1. Choose a selection mode: Append Either press and hold Ctrl or click Selection Mode and select Append. Replace Either press Alt or click Selection Mode and select Replace. Remove Either press and hold Shift or click Selection Mode and select Remove. 2. Select surfaces by clicking on them individually or drag selecting them. With drag select, surfaces that are entirely contained in the selection box are selected - even those hidden behind other surfaces. For example, with just a few clicks, you can select all the main pipes, then zoom in and click or drag select to add the rest of them: Figure 24 Surface Selection Mode You can select Change Highlight Color the viewport. from the View menu or by right clicking in Page 50

62 7 Selecting Surfaces for Classification 3. To pan or zoom, use the mouse wheel and arrow keys, or change the navigation or projection from the toolbar. Selected surfaces will remain selected while you move around the model. You can then return to a selection mode. 4. Switch between different modes to select exactly the right surfaces are highlighted. Append and Remove modes toggle: if you click on a surface that is already selected, it will be deselected, and vice versa. 5. To check what you ve selected, right click and select Only Show Selected Geometries. 6. You can deselect all selected surfaces: right click and select Clear Selected Geometries or switch to Replace Selection. 7.4 Classifying Surfaces into Geometry Groups 1. Select the surfaces you want to identify as a group. 2. Right click in the viewport and select Move Geometries or Merge Geometries: Move puts them in a folder together, but keeps them as individually selectable surfaces. Merge combines them as a single surface: click anywhere on it in the viewport and you select all of it. 3. You see the Choose Destination dialog: If your Merge includes surfaces from two different models or two different geometry groups, some of the surfaces will be moved as well as merged. For example, if you have models Tower Top and Tower Base, and you select surfaces from both, which you then merge to a subfolder of Tower Top, surfaces that were in Tower Base, will now be in Tower Top. Page 51

63 7 Selecting Surfaces for Classification 4. To create a new folder for the selection, select a parent folder, then select Add Group. Right click on the new empty folder, called New Group Node, and select Rename. 5. Select the destination folder, then Add Geometry. The selected surfaces are added to that folder, which you can then rename. 6. Select the geometries and click OK to save the changes and add them to the Scene Tree. Then click Save to save the changes to the project. You can also Add Group and Add Geometry from the context menu of the Scene Tree. See Creating Geometry Groups in the Scene Tree on page Geometry Properties and Color Classification The Properties window shows details of what is selected in the Scene Tree window, including vertex bounds and counts. Figure 25 Geometry Properties Page 52

64 7 Selecting Surfaces for Classification Change Geometry Group Colors By color-coding groups of surfaces, you can develop a clearer visualization of your data, without changing the underlying data. For example, grey for walls and floor, red for 5-inch pipes, blue for 3- inch pipes, and yellow for everything else. The geometry group colors are superimposed on whichever coloring method you have currently selected for your mesh model: solid color, RGB texture, or intensity texture. 1. In the Scene Tree window, select a geometry group. 2. In the Properties window, click in Surface Color, Line Color, or Line Thickness fields: If the field shows the default, Inherits from Parent, clicking the Browse button opens a standard color selector. If the field is set to a color, clicking in it shows a Browse button to open a standard color selector and a chevron to reset it to inheriting: Figure 26 Mesh Model with Color-Coded Geometry Groups and RGB Texture Page 53

65 7 Selecting Surfaces for Classification 7.6 Deleting Selected Surfaces To delete surfaces from the mesh model, select them, as above, then right click and select Delete Selected Geometries. See also Cropping on page Exporting Selected Surfaces You can export some or all of the surfaces directly to Autodesk BIM 360 or to file formats that you can use in other CAD software for the next stage of your workflow. FBX and IFC are particularly good at retaining surface classification, and you can include a texture, such as RGB, when exporting to OBJ, DAE or FBX. See Export on page 70. Page 54

66 8 Editing Point Clouds and Mesh Models 8 Editing Point Clouds and Mesh Models 8.1 Overview of Editing Tools You can crop point clouds and mesh models, create plans and sections of mesh models (including multiple cross-sections at specified intervals), and create scaled orthographic images of point clouds and mesh models. You can also measure between multiple pairs of points, on a mesh model or point cloud Example Workflow for Editing Models 1. Open or create a project containing a point cloud. 2. Editing is easier with the Orbital camera ; you may also prefer Orthographic projection (instead of Perspective) and want to change the background color. 3. Crop the point cloud to the area of interest. 4. Create orthographic images of some or all faces of the point cloud, each with a scale bar. 5. Build a mesh model from the cropped point cloud. 6. Edit the mesh model by further cropping. 7. Create a plan, or multiple cross-sections, of the mesh model. 8. Create orthographic images of some or all faces of the mesh model. 9. Take measurements and snapshots of the model. 10. Upload the mesh model files to Autodesk BIM 360 or export to file formats DAE, DXF, FBX, IFC, NWC, OBJ, SKP, or STL. If exporting to OBJ, DAE or FBX, you can include a texture in the export. Page 55

68 8 Editing Point Clouds and Mesh Models 8.2 Selection Tools and Controls When you select an editing tool, selection controls are superimposed on the model: a cuboid (or, for plans and sections, a flat plane) containing the selection area. There are also green, red and blue circular rotation controls in three planes for adjusting the position, size and rotation of the selection cuboid or plane. Vector Model Selection Cuboid Handle to Move Position of Cuboid Handle to Move Position of Cuboid Rotation Control (not selected) Rotation Control (selected) Figure 27 Crop Mesh Model, with Selection Tools Labelled Tilt, rotate and zoom to find the ideal viewing angle: move the model using the regular mouse, 3Dconnexion mouse and cursor keys, as normal (the selection controls move with it). Use the regular mouse to select and control individual selection tools. You can also use the Tool Dialog Selection Controls, described on page Position, Size, Rotation and Lock Controls The Crop, Plans/Sections, and Ortho Images tools all work in a similar way: select a tool, adjust what is selected, create the output, then either select a different part of the model, or close the tool. You select part of the model using the controls in the viewport and/or the related values in the edit tool window. For example, if you change the rotation in the viewport, the rotation values will change accordingly in the tool dialog Viewport Selection Controls The viewport controls are intuitive, but take care to select the one you want before moving it: Hover over a face of the selection area to select it (it darkens). Then drag to shrink/enlarge. As it resizes and moves, the circular rotation controls adjust as well. Hover over a white handle of a circular rotation control to select it and then shift the position of the whole cuboid/plane (and associated rotation controls) in the direction you move it. Hover over, or close to, a circular rotation control so that it is brighter and thicker, indicating that it is selected, as for the green one illustrated in Figure 27, above. Move the regular mouse to rotate the selection area in that plane; use the 3D mouse to adjust the whole view. Page 57

69 8 Editing Point Clouds and Mesh Models Shft+ArrowKeys, PageUp, PageDown, moves the box in all 6 directions If you tick to Lock the Position, Size and/or Rotation fields in the tool dialog, the corresponding controls will be removed from display in the viewport until you untick Lock. Selection with different tools: Plans/sections: There is a selection plane, rather than a cuboid. Ortho images: The faces are labelled Left, Right, Front, Back, Top, Bottom by default, as in Figure 30 on page 60. Cropping: The selection cuboid is unlabeled, as in Figure 27 on page 57. If the selection cuboid is opaque, switch on antialiasing: View > Antialiasing. You may also find it helpful to change the background color: View > Change Background Color Tool Dialog Selection Controls In addition to the click/drag controls in the viewport, you can adjust the selection cuboid in any edit tool dialog. Click the Selection Tool tab that is initially at the bottom of each edit tool dialog: Figure 28 Selection Tool tab of an Edit Tool Dialog This displays Selection controls like those in fields. Figure 29, below, in place of the Output Page 58

70 8 Editing Point Clouds and Mesh Models Figure 29 Selection Tool Controls in an Edit Tool Dialog The Selection Tool tab is the same on all the edit tool dialogs. The Position, Size and Rotation of the selection cuboid will be the same if you switch between Cropping, and Ortho Images tool, until you adjust or Reset All (or use viewport another tab). Page 59

71 8 Editing Point Clouds and Mesh Models Figure 30 Labels on Faces of a Selection Cuboid Adjust the section cuboid by editing the values for Position, Size and Rotation, and corresponding changes are immediately shown in the viewport. Tick to Lock any of those dimensions. The corresponding controls are greyed out in the dialog and removed from the viewport. The selection can only be adjusted in dimensions that are not locked. To reset the position of the point cloud or mesh model, click Reset (or press R). To reset all the editing tools (cuboid/plane and circular rotation controls), click Reset All in the edit tools window Create New File(s) from Edit When you are using an editing tool and click Create, new file(s) are created, but the dialog stays open: Crops (see page 61) Cropped point clouds and mesh (vector) models are stored in the selected scan folder s Point Clouds or Vector Models folder, respectively. Display in a viewport tab to do further editing. Plans and Sections (see page 64) Create a single plan, or multiple sections at specified intervals. The 2D plans and sections are stored in the selected scan folder s Plans/Sections folder. If you double click one in the Project Explorer, it will open in a new tab, but you cannot edit it in Pointfuse. Ortho Images (see page 67) Orthographic images are 2D raster images, stored in the project s Ortho Images folder. If you double click one in the Project Explorer, it will open in a new tab, but you cannot edit it in Pointfuse. Page 60

72 8 Editing Point Clouds and Mesh Models 8.3 Cropping Start with a 3D cuboid comprising one or more point clouds or mesh models, and create a single 3D cuboid that is a subset, but in same format as the source. To delete selected surfaces, such as floors or pipes, see Selecting Surfaces for Classification on page 47. Crop point clouds to get rid of unwanted points (e.g. clutter at the edges), and to reduce file size, which will make it quicker to build a mesh model. Crop mesh models to create smaller models of specific areas, e.g. to reduce visual distraction and to make zooming to the area of interest quicker. You can crop when you have a mix of point clouds and mesh models displayed in the viewport tab, but you can crop only one type at a time, to create a new file of the same type. 1. Open a project and display the point clouds or mesh model to crop. 2. Click Crop. 3. The Cropping Tool dialog is displayed: Figure 31 Cropping Tool Dialog (Output tab) Page 61

73 8 Editing Point Clouds and Mesh Models 4. A selection cuboid is displayed around the point cloud/model. 5. Optimize the view, e.g. by tilting the model and changing the background color, or by using the Selection Tool tab. See Selection Tools and Controls on page Specify a Name and optional Description for the cropped file. 7. If you have a mix of Mesh (Vector) Models and Point Clouds displayed, select which format you want to crop. The result will be a new, cropped file of the same type. 8. If you have classified surfaces and hidden some from display in the Scene Tree (see Selecting Surfaces for Classification on page 47), choose whether to Include Only Visible Items. 9. By default, the contents of the selection cuboid will be copied to the new file. If you want to remove the selection, tick Invert Selection; this will be remembered for the current session of Pointfuse, even if you open a new project. 10. If cropping a mesh model, you can choose whether to Include Textures. 11. Either select an existing Scan folder from the dropdown list, or tick Create New Scan and specify New Scan Name. 12. Use the selection tools in the viewport to adjust what to crop (see Types and Uses of Editing Tools on page 56). Alternatively, adjust via the Selection Tool tab. 13. Click Create. 14. The result is added to the specified scan folder in the Project Explorer but is not displayed in the viewport. Instead, you stay in crop mode, to allow further cropping. 15. When you have finished cropping, click Close. 16. Display the results in the viewport. For example: Figure 32 Cropping: Before (left) and After (right) Page 62

74 8 Editing Point Clouds and Mesh Models 8.4 Plans and Sections Create 2D plans and sections from a 3D mesh model. You can create sections at regular intervals, e.g. at different heights so there is one for each floor of a building. The size and position of the selection plane and the other settings in the tool dialog are remembered for the current tab. This makes it easier if you create multiple sections, look at the results, and want to tweak the settings before creating new sections. 1. Open a project and display a mesh model in the viewport. 2. Click Plans/Sections. If you have more than one mesh model displayed in the viewport, you will be prompted to choose which one the plan or sections are created from (any point clouds will be ignored). Select a file and click OK. 3. The Plans/Sections Tool dialog is displayed: Figure 33 Plans/Sections Tool Dialog (Output tab) Page 63

75 8 Editing Point Clouds and Mesh Models 4. A selection plane is displayed through the model. 5. Optimize the view, e.g. by tilting and zooming to see the selection plane, rather than just its white edge, or by using the Selection Tool tab. See Selection Tools and Controls on page 57. Figure 34 Creating a Plan/Section of a Mesh Model 6. Specify a Name and optional Description for the plan or sections. 7. Optionally tick to Draw Border around the resulting image. The border corresponds to the edge of the selection plane. 8. Optionally tick Create Multiple Sections. If ticked, you can: a. Specify the Number of Plans / Sections. b. Define the Spacing between sections. The additional sections will be taken at specified intervals above the selection plane. 9. Use the selection tools to adjust the selection plane. By default, this is a horizontal slice, but you can change X or Y rotation to take a vertical or diagonal slice. To create multiple horizontal sections (see below), position the plane at the lowest level you want to section. 10. Click Create. 11. The plan or sections are added to the Plans / Sections folder under the same scan folder as the source, but not automatically displayed in the viewport. 12. To create further plans and sections, adjust the selection plane, either by moving it directly or by changing the Position value in the Plans/Sections Tool window. Click Create after each one. 13. When you have finished, click Close. Page 64

76 8 Editing Point Clouds and Mesh Models 14. Display the result in the viewport and optionally export it. For example, a plan of the tower in Figure 34: Figure 35 Plan/Section of a Mesh Model The grid, projection and camera settings are automatically switched off when viewing plans/sections (and other 2D data). 15. To create more plans or sections, with slightly different settings, click to open the dialog again. The size and position of the selection plane and the other settings in the tool dialog will be the ones you just used. If you want to start from scratch, either click Reset All, or open the model in a new tab. Page 65

77 8 Editing Point Clouds and Mesh Models 8.5 Orthographic Images Select a 3D cuboid as for cropping, but create 2D orthographic images of each face. Each image includes details of scale (see Figure 38 on page 69). They are raster (not vector) images, so cannot be edited in Pointfuse, though you can display them, one per tab. Ortho images use Orthographic projection. If the viewport is displaying files in Perspective projection, you will notice the difference. 1. Open a project and display data in the viewport. Orthographic images contain all visible parts of point clouds and mesh models currently displayed in the viewport. Mesh models will be rendered using the currently selected rendering option (see toolbar); for point clouds, you select the rendering in this dialog. 2. Click Ortho Images. 3. The Ortho Images Tool dialog is displayed. Figure 36 Ortho Images Tool Dialog (Output tab) Page 66

78 8 Editing Point Clouds and Mesh Models 4. A selection cuboid is displayed around the model, with faces labelled Front, Back, Left, Right, Top and Bottom. 5. Optimize the view, e.g. by tilting the model and making the edges of a building parallel with the edges of the selection cuboid. See also Selection Tools and Controls on page 57 and View Position on page 43, 6. Specify a Prefix and optional Description for the orthographic images. 7. Adjust the Scale of pixels per meter (default is 100). 8. Select a Background Color. 9. Switch Multisample on or off. Multisampling uses more resources, but creates a clearer image. 10. For point clouds, select a Point Size, between 1.00 and 10.00, and you can change the Rendering Method (the default is the current viewport setting). 11. For mesh models you can change the Rendering Method (the default is the current viewport setting). 12. Tick which Cuboid Sides you want to create orthographic images of: Front, Back, Left, Right, Top and Bottom, as labelled on the selection cuboid. Adjust the cuboid if necessary. 13. Click Create. 14. The orthographic images are added to the Ortho Images folder. They have the name you specified, appended with the name of the face in brackets, e.g. church tower (Front). 15. To create orthographic images from a different cuboid, adjust the cuboid, either by moving it directly or by changing values in the Ortho Tools window. 16. When you have finished, click Close.

80 9 Export 9 Export Mesh Model You can save mesh models in industry-standard formats to use in other software for the next stage of your workflow. You can upload directly to your Autodesk BIM 360 account, or save models in formats suitable for other CAD and related software. If you have previously classified surfaces, you can selectively export them. For example, you can export a building, without the floor, or just the pipework. See Selecting Surfaces for Classification on page 47. The trial version of Pointfuse limits you to three exports, whether to Autodesk BIM 360 or your PC. After that, you need a Pointfuse license to do further exports. 9.1 Supported Export File Types You can export some or all of the surfaces of a mesh model to the following formats: File Suffix Associated With Good for Keeping Surface Classification Hierarchy? Can Include Textures? For 2D Plans/Sections? Other Files Created DAE Collada Yes, see page 33 PNG DXF Drawing Exchange Yes Format FBX Filmbox Yes, see page 47 Yes, see page 33 PNG IFC NWC Industry Foundation Classes, for Teckla Structures, Revit, ArchiCAD and others Navisworks Yes, see page 47 OBJ Wavefront Yes, see page 33 PNG and MTL SKP SketchUp STL StereoLithography Yes Table 7 Export File Types and Features If an export does not include textures, any PNG and MTL files will be empty.

Click Save to return to the main dialog, which now displays the path and name for the exported file. 4. If exporting to OBJ, DAE or FBX, you can select which texture to include (see Color by Textures on page 33). 5. By default, all surface geometries currently displayed in the viewport are ticked, but you can change which are included in the export by ticking or unticking them in this dialog. See Selecting Surfaces for Classification on page Click OK to create the export file. 7. You can open the export in a CAD or similar program, but not in Pointfuse. Page 72

84 Appendix A Toolbar and Menu Functions Appendix A Toolbar and Menu Functions Toolbar functions are also on menus (though not all menu items have a corresponding toolbar button). Tooltips either display the name (e.g. Open Existing Project) or current value (e.g. Perspective). Functions are described in the relevant sections of this user guide, and summarized below. Figure 43 The Toolbar Button Shortcut Function Comments Applies to Page Ctrl+N Create new Project - 12 Ctrl+O Open Existing Project or File Enabled when not running a task.

88 Appendix C Defining Preferences and Defaults Appendix C Defining Preferences and Defaults Customize Pointfuse by defining defaults for how the interface looks, how you move around it, and how data is displayed. Use Options > Preferences > Restore Defaults to revert. You can also define processing profiles to determine the resolution used when building mesh models from point data. From the Options menu, select Preferences, to open a tabbed dialog. C.1 General Tab These are global defaults that take effect when you click Apply or Close. Page 77

89 Appendix C Defining Preferences and Defaults See Antialiasing and Smoothing on page 35. See Caching on page 81. See Invert Mouse (Regular) on page 43. See Enable 3Dconnexion Mouse on page 43. C.1.1 Caching Caching is enabled by default for more efficient processing of point clouds. This is especially important when building mesh models from large point clouds. It creates temporary folders in the location specified here. If your computer has a solid state drive, set the caching folder to be on that drive. Page 78

90 Appendix C Defining Preferences and Defaults C.2 Visualization Defaults Tab The fields on this tab all relate to how point clouds and mesh (vector) models are displayed by default, in future; existing tab contents are unaffected. Therefore, the Apply button is only enabled if you have changed something in another Preferences tab. In contrast, if you change a setting from the toolbar or menu (Camera, Projection, Antialiasing, Smoothing, Shading Method and those listed as General), it only applies until you change it again, or you close Pointfuse. Use Options > Restore Defaults to revert to factory settings. See Changing How the Model Looks on page 30. See Viewport Settings on page 37. Page 79

91 Appendix C Defining Preferences and Defaults C.3 Processing Profiles Tab A processing profile determines the resolution used when converting point data to mesh models. In this dialog, you can view the profiles installed with Pointfuse (suitable for point clouds built from Terrestrial, Mobile or Airborne technology) as well as create and edit any custom ones. See Creating Custom Processing Profiles on page 28. Page 80
