3 3d Graphics & User Interfaces

4 Famous 3ds MAX. Since MS-DOS. Officially announced 3ds MAX at Siggraph 1995

7 How to use computer software? GUI (Graphical User Interface) Menu Icons / Toolbar Typing, Clicking, Drag and drop, Key stroke Tabbed (grouped) Icons / Toolbar (Ribbon Interface by Microsoft)

8 How to interact with computer software? User Interfaces, as of 2014 CLI Command Line Interfaces - Command prompt GUI Graphical User Interfaces - Windows, Mac NUI Natural User Interfaces - Touch, motion, voice.. General software we use today General CG software: for Efficiency and Precision e.g. AutoCAD command line

9 Why 3d graphics software is very hard to learn? This gap makes you hard to learn 3d graphics! Ideal interfaces for 3D modeling - 3d laser scanning (from real world objects) - Image processing (from 2d pictures to 3d model) - Beyond keyboard & mouse: Tangible devices for manipulating 3d objects in 3d way Most 3d graphics tools - Handling 3d objects on 2d screen! - Too complicated 3d modeling on 2d views - Too many icons! (limitation of GUI) - Too complex options, too many function

10 3d modeling with keyboard & mouse only? of course not isphere CAVE And so on. 3D bricks (Fjeld et al. 1998) Paddle (Kato et al. 2001)

11 Example - Another 3d modeling method: Laser Scanning Point Cloud Laser Scanner Scanning

12 Video: Laser Scanning Laser scan Faro laser scanner ad Laser scan CCA at San Francisco

13 Example: Laser Scanning

14 Example: Laser Scanning

15 Example: Laser Scanning

16 Import point cloud in Revit, and modeling

17 In Revit, move height, install camera, and model its BIM

18 Example - Another 3d modeling method: From 2d pictures to a 3d computational model Autodesk Gallery, SF 3d JK Lee

19 An Example: Autodesk 123D Catch Google image search

20 Google Project Tango Smart Phones to 3d Building interior Video

21 Actual reason why 3d graphics software is too hard to learn? We need to understand behind technologies, rather than User Interface issues! Ray tracing, global illumination Bump mapping, Phong Shading Bezier curve, Spline, NURBS, control point, segments UV mapping, UVW Polygon mesh Sweeping, lathing Knowing about camera and lenses focal distance, aperture, exposure Without understanding what are these, learning 3ds MAX is equivalent to memorizing the order of clicking buttons among hundreds of icons, in a messy GUI interface. If you understand the logic, rather than the order of clicking buttons, you can learn any complicated modern 3d modeling & rendering software such as Rhino, Maya, Blender, Digital Project, and so on, of course including 3ds MAX.

22 3d Geometric Modeling

23 Geometry for making 3d objects Modeling 3d object: Creating an object (hard to do, except making primitives) And Modify it (very hard to do modify geometry s subcomponents)

24 3d modification, by editing 2d geometry

25 Creating 3d objects 0 Making Primitives A legendary Utah Teapot, developed by Martin Newell

26 Modeling starts from primitive geometry How to create a new 3d object? - Create primitives - Extrusion - Sweeping (lathing, loft..) - etc. And then, modify them again and again

27 Modeling tools in 3ds MAX Standard Primitives Extended Primitives Modifier

28 3ds Max primitives + 3 Photometric Lights + Autodesk Material + Mental Ray Render image, all done just in 5 minutes

29

30 Creating 3d objects 1 Extrusion: extruding a polygon Push/pull tool in SketchUP

31 Creating 3d objects 2 Lathing: revolving a surface

32 Creating 3d objects 3 Sweeping: sweep a section profile onto a polygon path

33 Creating 3d objects 4 Others: Skinning, Boolean operation (CSG)

34 & More: Import CAD file and make a building Import AutoCAD floor plan file - Check Units - Choose Layer

35 More Example: Parametrically defined Geometry: AEC Extended in 3ds Max

36 More Example: Parametrically defined Geometry: AEC Extended in 3ds Max

37 More Example: Parametrically defined Geometry: AEC Extended in 3ds Max

38 Learning 3ds Max Design + Mechanism, NOT just interfaces of 3ds Max Design

39 What to do in 3ds MAX (& other general 3d tools) 1 (Geometric) Modeling: Create objects Modeling Difficult and time-consuming 1 Create 2d geometry and 3d objects 2 Import pre-defined 2d/3d objects 3 Manage objects: object modification 2 Rendering: Visualize scenes Rendering Many things to take care of 1 Assign materials 2 Add lights 3 Setup cameras 4 Rendering options & render scenes 3 Animation: Animate scenes Animating Many renders. Hardware dependent

40 3ds MAX use scenario in interior architecture design Define UoD What s in your mind? - Roughly sketch it freehand if needed - Plan hierarchy diagram and objects (Geometric) Modeling Modeling universe (environment) Planes Walls Modeling design elements 2d sketch 3d modeling Sky, outside view Modification Import Modification Rendering Material mapping Lights Camera Rendering scenes Retouching in 2d Graphics Tools Photoshop (or others) supports lots of complicated effects - Modify: Level, Color balance, Sharpness, Gaussian blur, etc. - Add: Remapping, Compose, Texts, etc.

41 3ds MAX use scenario in interior architecture design Before modeling & rendering Defining UoD first! Roughly design your universe This UoD is not reflecting real world totally visualization purposed fake surfaces 3d Geometric Modeling is very hard and tedious Reuse pre-defined object models Use pasted bitmap images for drawing section profiles Model in 3ds MAX, not in AutoCAD (when AutoCAD plan is ready, then use it) Make all edges smooth e.g. NURMS, Bevel Rendering basics Use high-quality bitmap images for mapping (doesn t mean only high-resolution) (Take pictures whenever you find good interior design material, and Photoshop) Three lightings and one camera for furniture, lots of lightings for interior design Use Mental Ray (or other ray tracing: e.g. V-Ray etc.) for global reflection Less is more Retouch in Photoshop or others, don t try too much in 3ds MAX. Don t forget your final result is just a mere 2d image!

42 Cartesian Coordinate System Work space: Model here! Steering Wheel View Cube Use Hotkeys!

43 Use hotkeys! Useful 3ds MAX hotkeys (basic keys) Viewing Alt + W : Maximize the viewport, and back G : Show/hide grids F3 : Toggle between wireframe view and Shading F4 : View edge face wireframe, available in shading view C : View camera, P : View perspective, T : top view, L : left view, F : front view, B : bottom view Ctrl + X : Toggle expert mode Shit + Z, Shift Y : Undo, Redo viewport operation +, - : Increase, decrease Gizmo size Object Handling Q : Click Selection tool W : Click Move tool E : Click Rotate tool R : Click Scale tool H : Select by name Ctrl A : select all, Ctrl D : deselect all, Space bar : selection lock toggle (keep selecting current ones only if turned on) & more hot keys! Setup your own customized keys Utility M : Material editor F10 : Render setup Shift + Q : Rendering
