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

SketchUP
3ds Max
SketchUP models are surface-based models
SketchUP model is 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.

Surface-based 3d visualization
is one of the easiest way of 3d
modeling and rendering

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
Lab Exercises: 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:
- 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
