In Review

• Assignment 6: Rhino I
• Assignment 7: Rhino II & InDesign

Assignment 10: Rhino III

Assignment 11: Vray

Coming up..

You can download Vray and installation instructions from the ArchPC server:

V-ray Install Instructions:
\\archpcserver\First Year Laptop Software\Documentation

V-ray Installer File Location:
\\archpcserver\First Year Laptop Software\V-Ray for Rhino

You must be on campus to use the university's license server (VPN possible). 

Limited licenses are available university-wide. So do not get caught up with night-before-deadline-frenzy.

Technical Tips

• You can disable notifications in both Modelo and RealtimeBoard
• Indesign - Display Performance setting

Housekeeping

• Any more invitation issues?
• Troubleshooting

Polygons vs. NURBS

Polygonal Modeling

NURBS (Non-Uniform Rational Basis Spline)

Based on Mathematical Model, Higher Level, More Intuitive

Points (Vertices) > Curves > Surfaces (Abstraction that's ultimately rendered as polygons)

Points (Vertices) > Triangles (Mesh)

Lower Level, Less Intuitive, More Efficient for 3D Rendering

Boolean Geometric Operations

All 3D computer graphics abstractions are fundamentally comprised of small triangles (facets, faces, etc.)

Through the process of Tesellation

Graphic Tessellation

Architectural Tessellation

Number of vertices needed grows with the amount of curvature in the geometry.

Try to imagine how many vertices/faces would be needed to model thin "piped" geometries.

e.g. Modeling hair is a difficult computational problem.
