Surface & Volumetric Techniques

Thursday, 25 July
10:30 am - 12:15 pm
Room 207

Session Chair: Ioana Martin, IBM T.J. Watson Research Center


Slow-Growing Volumetric Subdivision
A new subdivision technique that refines volumetric meshes at the same rate as surface meshes. The scheme builds adaptive refinements and sharp edges without using special cell decompositions.

Modified Marching Octahedra for Optimal Regular Meshes
Volumetric data on cubic meshes are not optimally sampled. Optimal meshes use tetrahedra and octahedra. This technique optimizes isosurfaces on these meshes by substituting octahedra for groups of tetrahedra.
