3 Again, Technical Note

4 1. Don t forget to register the Course Web

5 2. Access the main PC (file server): 504-Main On Windows7, - Click Start - Type \\504-Main (two back-slash and PC name = trying to access network) - You may find out Shared Folder Current Local Area Network (LAN) is slow. 30 PCs cannot access at the same time. USB drive will be given by me for sharing the files if you cannot access 504-main. In the Shared Folder, you may find out three things: - Course slide files - Lab Exercise files - Your name folder, under the Student folder Submit your Lab Exercise files

6 3. Save material on your USB or D drive: Keep clean the PCs Save the files from the Shared Folder into your USB drive, or D: drive on your PC (some PC has only C: drive, then save on C) ( 본인의 USB, 또는 PC 의 D 드라이브에수업관련파일을항상복사 본인 USB 또는외장하드항시지참 ) Never try to run (double-click) the files in the Shared Folder directly it s not your PC ( 네트워크상에서직접파일더블클릭절대금지 반드시 USB 나 D 에복사후실행 ) Never save the files on your PC s Desktop save them in your USB or D drive ( 컴퓨터바탕화면에파일저장금지 수시로지워질수있으므로본인 USB 또는 D 드라이브사용 ) Files on Desktop will be removed occasionally Never try to install any kind of software keep the PCs safe ( 바이러스등의위험으로소프트웨어 ( 특히 lol) 설치금지 언어 / 지역설정변경금지 ) ( 만일필요에의해설치또는언어변경시반드시원래대로복구후 PC 종료 )

7 4. Autodesk student community access Autodesk provides 3-year free software for students Login into Autodesk Student Download Center You can get the Keys for following major Autodesk software for designers: - AutoCAD dsMAX Design Revit and so on - new version software will be updated annually (2016 version comes in 2015 Spring) You can access your keys again whenever you login into Autodesk Student site for installing on your PC, laptop, etc. (3 times activation limit)

8 Autodesk Student Download Free Autodesk tools

9 For the Class & Lab Exercises: Some regulations 2 hours lecture + 2 hours lab exercises OR 1 h + 3 h Bring your USB drive: Save Lecture Slides & Lab Exercise files every week! Given lecture slides & lab exercise files are on the local area network: \\504-Main computer s shared folder (Never directly run on the network copy them on your PC, and run) No homework: Every assignments should be done in the class! Copy your files on your name folder under the Student folder ( 반드시숙제는해당일실습시간에완료후본인이름폴더에저장 네트웍이나 USB 이용하여 504- Main 컴퓨터의공유폴더아래 Student 폴더밑에복사 ) After the class, Student folder will be copied and removed within few hours ( 본인이름폴더들은수업종료한두시간이내에해당일복사후삭제됨 )

10 Communication for the class Basically this is a class of using digital Use several computing tools for the course Course Website is the official communication channel for the course Course Web: open to class members Professor s designit@hanyang.ac.kr SNS Office: College of Human Ecology, Room #511 Individual student meeting is on schedule. (After the class, 2~3 students per week)

11 Surface-based 3d Modeling & Visualization

12 Surface-based 3d model (polygon-based) based on SketchUP & 3ds Max

13 History of computer-aided design is a history of understanding what is design The design is a drawing of the product e.g. Geometric drafting in 2D The design is a surface model of the product e.g. Geometric surface modeling in 3D SketchUP 3ds Max The design is a 3D model of the product e.g. Solid modeling The design is an editable 3D model of the product e.g. Parametric modeling H W D Parameters: H, W, D The design is the integrated representation of all the compositional, analytical and fabrication representations of the product (Geometry is just one part of the model) e.g. Product Data Modeling, Building Information Modeling + Information Information Modeling

14 SketchUP & 3ds Max models are surface-based models SketchUP & 3ds Max models are Surface 3d, NOT Solid 3d

15 Edge & Face made a sketchup model Edge (Line) & Face (Surface) Surface-based 3d model

16 All lines are actually straight A curve is a collection of straight lines Any organic-shaped curves are still straight lines

17 All surfaces are actually flat A surface (face) is a collection of edges (lines), at least three edges Any organicshaped surfaces are still a collection of flat surfaces

18 Diffuse: color or a texture map on the 3D surface A surface can be colored. A surface can be texturemapped. Realistic 3d visualization

19 Diffuse: color or a texture map on the 3D surface Surface-based 3d visualization is one of the easiest way of 3d modeling and rendering

23 Rendered by V-Ray plugin, on SketchUP

24 Download V-Ray renderer for SketchUP (demo version) Install it: V-Ray plugin panel icons will be available as shown below

27 Renderer: SketchUP + Vray

28 Rendering basics all about lights Lighting Source - Direct Illumination (e.g. Sunlight) - Indirect Illumination - Environment Target Objects - Diffuse - Intensity - Texture Map - Shadow casting - Ambient Occlusion - Reflection - Refraction - Caustics Camera - Source, Target - Field of View

29 Rendering Overview

30 Diffuse For Transparent Bitmap BG Color Texture Map Transparency: White = Transparent, Black = Opaque BRDF: bidirectional reflectance distribution function

31 Reflection Reflection color: White Transparent, Black Opaque Reflection Glossiness

32 Refraction IOR: Index of Refraction

33 Emissive

34 SketchUP & Vray render tips

35 Save & Use PNG files for transparent background In most cases, PNG file format is one of the best file formats because it supports full color with transparent background. (JPG couldn t do this, GIF could but limited colors)

36 Texture Mapping Right button Texture - Position: Control red, green, yellow, blue control pins - Projected: Project texture to other surfaces

37 Bump Mapping (& Displacement, etc.)

38 Dynamic SketchUP Component Always face camera: Set it when creating components

40 Renderers: Vray & Mental Ray (MR)

41 Brazil: or other renderers - Pros: Amazing render quality, great shaders. Not as complete, always seems unfinished. Great lights and other addons. - Cons: Slow renders, limited GI options for animation. - Cost: One license, two render nodes free. Cost per render node after that. Mental Ray vs. Vray vs. Brazil, and more renders VRay: - Pros: Fast ray trace, intiutive interface. Include exclude objects. Great GI options. Great area lights. Vray proxies, fur etc - Cons: Bad shader support, limited in getting under the hood. Render's look chalky - Cost: One license, 99 render nodes free. Mental Ray: - Pros: Embedded in 3ds MAX. Great materials, and shaders. Great render quality. You can get under the hood with standalone. Arch & Design, promaterials - Cons: FG for animation is weird, and having used other renders, it falls way short. Lack of GI options. No brute force. Maya seems to have better integration for shader networks. Multiple versions for multiple max releases. So you have to upgrade max to get the new MR. Bad decision. - Cost: free with max native, free rendering. Costs a small fortune for standalone.

42 Mental Ray (in 3ds Max) - Use preset Arch & Design Material / ProMaterials (Autodesk Material)

43 Material basics Standard Many tutorials Arch & Design, ProMaterials Use Presets

44 Arch & Design Presets in 3ds MAX with Mental Ray presets

45 Arch & Design Material with Mental Ray In October of 2006, Autodesk implemented a material type called the Arch & Design material for the 3d Studio Max implementation of mental ray. Easy to use, yet flexible: complicated than Vray but simpler Templates: fast access to common materials Physically accurate Glossy performance Tweakable BRDF (Bidirectional reflectance distribution function) Transparency Round corners: make it realistic catch the light on edges Indirect Illumination control Built-in Ambient Occlusion Ray-traced & photo-realistic preset materials
