Results on Energy Minimizers

Paper Presentations

Arnt Fredricksen:
NM'00:  "Normal Meshes"
Guskov et al

What is the key insight that allows meshes to be represented with just one scalar value per vertex (with a few exceptions) ?
Why is the choice of the starting mesh really crucial ?
What are the main steps of the construction algorithm for normal meshes ?
How are normal meshes related to subdivision surfaces and fractal mountains ?

Kenrick Kin: 
AL'03:  "Anisotropic Polygonal Remeshing" Alliez et al

Why is such a re-parametrization desirable ?
How is the curvature field sampled, constructed ?
Why is there a restriction to genus 0 on page 2 ?
What routines, programs is the algorithm built upon ?
What is the key advice about implementation given in the paper ?


A genus-3 object with suitably aligned quadrilateral parametrization.


READ: 
NR'98:  Non-Uniform Recursive Subdivision ...
TS'03:  T-Splines and T-NURCCs

The 3 teams who implemented quad subdivision, please have your demos ready for Thursday.
