Yusuke Yasui:
VB'98:  "Voronoi-Based Reconstruction"  N. Amenta et al

Quiz-Questions:
1.) What is an r-sample from a surface ?
2.) What is Voronoi filtering ?
3.) Why is it more difficult to do this in 3D ? -- And what can be done about it ?

Paul Liu:
PM'96:  "Progressive Meshes"  H. Hoppe

Quiz-Questions:
1.) What are the benefits of the Progressive Mesh representation ?
2.) How is such a representation constructed ?
3.) What are the key geometric operations at the mesh level ?

Discuss final Quiz problems


READ: 
NM'00:  Normal Meshes
AL'03:  Anisotropic Polygonal Remeshing

Current Homework Assignment: 
Determine the minimum energy for your genus-L surface (Phase 3)

Find a script to evolve your genus-L surface into a smooth shape with minimum bending energy while maintaining the specified symmetries.
E-mail me your  .fe-file with the successful script and a nice captured picture of the final shape.
Also: Let me know what the final total energy is of your smooth shape;
and state what crucial things you learned about how to use the Surface Evolver to make your initial polyhedron converge to a smooth shape.

DUE:  Tuesday, November 14, noon.
