CRYSTAL: A Matlab Package for 3D Mixed Subdivisions

This is a preliminary release of some code co-authored with my research assistant Zhigang Zhang. The output is in OOGL format for visualization by Geomview. More documentation will appear soon but in the mean time please feel free to pester Zhigang or myself.

• convhullng.m: a Matlab program which computes 3D convex hulls of finite point sets, WITHOUT
• getconv.m: Retrieving convex hull info from a file.
• subdiv3d4p.m: computes the mixed subdivision of 4 polytopes in 3D.
• subdiv3d.m: computes the mixed subdivision of 3 polytopes in 3D.
• sub2file.m: converts the precomputed mixed subdivision information into an OOGL file.
