4 Lights in 3ds Max & MR - Photometric Light (or similar): Ray-traced lights for rendering scenes photo-realistic and professional

5 Photometric Light On and off the light On and off Shadows Enable to exclude user selected objects Light Distribution type: Photometric Web, Spotlight Select color presets and filter color Intensity in cd (candela) Brightness control Emit light from point, line, cylinder simply control blurred shadow Interior environment (wall surfaces, etc) must be flipped (Flip) for applying lights (otherwise, always dark inside)

6 MR Sky Portal & MR Light Photometric Light for MR (Vray Light for Vray) Target Light Free Light: Point, Rectangle, Sphere, Disc Mr Sky Portal: Bring the sun!

7 Photometric Light

13 Photometric light Spotlight & IES light

14 Camera in 3ds Max - Focal Distance & FOV ( 카메라렌즈의초점거리와화각 ) - Multi-Pass Effect: Depth ( 카메라렌즈의심도 )

15 Focal Distance All about the lenses Focal Distance Lens: Focal Distance in millimeter 50mm Wide Sensor (Eye, retina) 85mm Tele Sensor (Eye, retina) FOV: Field of View: Angle degree Field of view angle

16 Effectively use Wide Lens! For architectural photo-realistic scenes, Especially for interiors, use (ultra) wide lenses and pick the best views Pros: Good to view all & professional Cons: Distorted Pros: Zooming in Cons: Narrow view Wide Lens Telescope Lens 15mm 24mm 35mm 85mm 200mm

17 200mm (Telescope Lens)

18 85mm

19 50mm

20 35mm

21 24mm (close to human eyesight)

22 15mm (Ultra Wide Lens)

23 50mm Lens vs. 15mm Lens (Non-wide Lens vs. Wide Lens) Effective on creating: Space perception / Impression of space Avoid too much distorted or exaggerated Effective on creating: Undistorted realistic graphic (Need to paralleled / orthogonal lines)

24 Picture Examples by Ultra-wide Lens & Tele

30 Depth of Field Make your scenes photo-realistic and professional!

31 Camera tips: Depth of Field Must select Depth of Field (Mental Ray) Multi-Pass Effect Enabled Depth of Field very slow but good effect Just render without Multi-Pass, and edit in great Photoshop Also effective, but amount of reduced time Deep Depth Shallow Depth Lower f-stop for shallow depth

32 Photo Example: Design by Zaha Hadid Architects, Autodesk SF Office

33 Focus zone & depth Out-focused

34 Out-focused Focus zone & depth

35 Without Depth of Field effect Focus zone (deep depth) Rendering elapsed time: few seconds

36 Depth of Field effect: to the second column Focus zone (shallow depth) Rendering elapsed time: a couple of minutes

37 Depth of Field effect: to the fifth column (red one) Focus zone (shallow depth) Rendering elapsed time: a couple of minutes

38 Depth of Field effect: Use Photoshop! Focus zone (shallow depth, generated by Photoshop) In Photoshop: elapsed time: around one minute 1) Properly select area 2) Feather 3) Gaussian Blur

39 Rendering Example using MR

41 Review: 3d Geometric Modeling

42 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)

43 3d modification, by editing 2d geometry

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

45 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

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

47 3ds Max primitives + 3 Photometric Lights + Autodesk Material + Mental Ray Render image, all done just in 5 minutes

48

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

50 Creating 3d objects 2 Lathing: revolving a surface

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

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

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

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

58 3d Geometric Modeling & Modifying

59 Geometric editing in 3ds Max For a specific geometric shape, there are various different ways In general, convert it into Editable Poly for editing sub geometric components such as vertex, edge, polygon, and use several useful Modifiers From Primitive: - Box, cylinder, sphere, etc. - Modify it, especially using Editable Poly - Editing vertex, edge, polygon - Use NURMS editing option for smoothed surfaces (Turbo smooth, Mesh smooth..) From 2d drawing - Poly Lines - Extrude, Sweeping (Loft in Max), Revolving (Lathe in Max), Morph - A lot of geometric editing tools Import specific objects (SketchUP, 3ds, FBX, max etc) and modifying them for the purpose

60 Editing Geometry Modifiers Editing Vertex Corner/Smooth/Bezier Weld Fillet Editing Edge Boolean, mirror Chamfer, Bridge, Connect Editing Polygon Extrude, Bevel Inset Flip Hinge from Edge Extrude along Spline Edit Poly (different from Convert into Editable Poly ) Use NURMS Subdivision (after converted into Editable Poly) FFD (Free Form Deformation) MeshSmooth, TurboSmooth

61 From 2d geometry to 3d model: Extrude 2d drawing Extrude 2d text Extrude

62 From 2d geometry to 3d model: Loft 2d text Extrude

63 From 2d geometry to 3d model: Lathe 2d drawing 2d modifying Lathe (revolving) to 3d

64 From 2d/3d geometry to 2d/3d model A box minus smaller box - A minus B, B minus A - Union - Intersection - Cut (two separated objects) Boolean operation is working on both 2d & 2d geometry and 3d & 3d geometry

65 Edit Poly or Editable Poly A box minus smaller box - A minus B, B minus A - Union - Intersection - Cut (two separated objects) Boolean operation is working on both 2d & 2d geometry and 3d & 3d geometry

66 Edit Poly From a Primitive (box) to an Object (spoon) using Edit Poly Careful & time-consuming control of Vertices, Edges, & Polygons

67 Edit Poly From a Primitive (box) to an Object (spoon) using Edit Poly A box with enough segments Rounded object, by moving Vertices, rescaling vertices, etc. Extruded handle by polygons, bended shape, etc.

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

69 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

70 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.

71 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!

72 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
