7. 3ds Max 2015 + MR: a city FBX file + MR sun 2 JPG files (morning, afternoon)

8. 3ds Max 2015 + MR: imported geometry 1 JPG file (best render scene)

3. Requirements: All lab exercises outcome files should be submitted in “Shared Folder”

Appropriate images in JPG format. Try to get your best render shots!

Again, Technical Note

1. Don’t forget to register the Course Web

https://sites.google.com/site/cadgraphicsiia2015/

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

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 PC의 D드라이브 에 수업관련 파일을 항상 복사 – 본인 USB 또는 외장하드 항시 지참)

Never try to run (double-click) the files in the “Shared Folder” directly – it’s not your PC

(네트워크상에서 직접 파일 더블클릭 절대 금지 – 반드시 USB나 D에 복사 후 실행)

Never save the files on your PC’s Desktop

save them in your USB or D drive

(컴퓨터 바탕화면에 파일 저장 금지 – 수시로 지워질수 있으므로 본인 USB 또는 D드라이브 사용)

Files on Desktop will be removed occasionally

Never try to install any kind of software – keep the PCs safe

(바이러스 등의 위험으로 소프트웨어(특히 lol) 설치 금지 – 언어/지역설정 변경 금지)

(만일 필요에 의해 설치 또는 언어 변경 시 반드시 원래대로 복구 후 PC종료)

4. Autodesk student community access

Autodesk provides 3-year free software for students

Login into Autodesk Student Download Center

http://students.autodesk.com

You can get the Keys for following major Autodesk software for designers:

- AutoCAD 2015

- 3dsMAX Design 2015

- Revit 2015

- 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)

Autodesk Student Download – Free Autodesk tools

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

(반드시 숙제는 해당일 실습시간에 완료 후 본인 이름 폴더에 저장 – 네트웍이나 USB 이용하여 504-

Main 컴퓨터의 공유폴더 아래 Student 폴더 밑에 복사)

After the class, “Student” folder will be copied and removed within few hours

(본인이름 폴더들은 수업종료 한두 시간 이내에 해당일 복사 후 삭제됨)

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 Email: 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)

Surface-based 3d Modeling & Visualization

Surface-based 3d model (polygon-based)

based on SketchUP & 3ds Max

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

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

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

D

Parameters:H, W, D

SketchUP

3ds Max

SketchUP & 3ds Max models are surface-based models

SketchUP & 3ds Max models are Surface 3d, NOT Solid 3d

Edge & Face made a sketchUP model

Edge (Line) & Face (Surface) Surface-based 3d model

All lines are actually “straight”

A curve is a

collection of straight

lines

Any organic-shaped

curves are still

straight lines

All surfaces are actually “flat”

A surface (face) is

a collection of

edges (lines), at

least three edges

Any organic-

shaped surfaces

are still a collection

of flat surfaces

Diffuse: color or a texture map on the 3D surface

A surface can be colored.

A surface can be texture-

mapped.

Renderer: SketchUP + Vray

http://www.vray.com/vray_for_sketchup/manual

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

Rendering Overview

Diffuse

Color

Texture Map

Transparency: White = Transparent, Black = Opaque

BRDF: bidirectional reflectance distribution function

For Transparent Bitmap BG

Reflection

Reflection color: White Transparent, Black Opaque

Reflection Glossiness

Refraction

IOR: Index of Refraction

Emissive

SketchUP & Vray render tips

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)

Texture Mapping

Right button – Texture

- Position: Control red, green, yellow, blue control pins

- Projected: Project texture to other surfaces

Bump Mapping (& Displacement, etc.)

Dynamic SketchUP Component

Always face camera: Set it when creating components

Renderers: Vray & Mental Ray (MR)

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.

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 (in 3ds Max)

- Use preset Arch & Design Material / ProMaterials (Autodesk Material)

Material basics

Standard

Many tutorials

Arch & Design,

ProMaterials

Use Presets

Arch & Design Presets in 3ds MAX with Mental Ray – presetshttp://www.mrbluesummers.com/3731/3d-tutorials/3d-studio-max-arch-design-preset-examples

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
