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.

Fracture Generation on Polygonal Meshes Using Voronoi
Polygons

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.
