- The expert is probably Herbert Edelsbrunner (edels@p.cs.uiuc.edu).
- Check the annual Symposium on Computational Geometry.
-
- 3D is qualitatively different from 2D in (at least) 2 ways:
-
- 1. Some polyhedra cannot be tetrahedrized w/o adding new interior
- vertices. All polygons can be triangulated.
-
- 2. For a given polygon, all triangulations of it have the same number of
- triangles. This need not be true in 3D.
-
- Ps. I am collecting qualitative differences between 2D and 3D geometry,
- and welcome suggestions.
