Surface Evolver: What works ? -- What causes difficulties ?
Quiz Questions:
1.) Describe in one sentence: How do Grinspun et.al model the resistance to deformations in thin-shell objects ?
2.) Under their flexure model, what deformations are possible for
icosahedral and dodecahedral shells with one face missing ?
Some calculated surface energies for sphere approximations using the above edge-based curvature model.
Which is the preferred operator ? -- Why ?
Who Got the Gold ? -- Result from the "Venture Capitalist Rally"

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.
DUE: Tuesday, November 14, noon.
