Tetra-Cubes: An Algorithm to Generate 3D Isosurfaces based upon Tetrahedra

Abstract:

We present the Tetra-Cubes iso-surface extraction technique. Tetra-Cubes is similar to the well-know marching-cubes technique, but its basic building block consists of tetrahedral cells instead of cubes. When the original are not tetrahedral cells, tetra-cubes just converts them to tetrahedra. We show that our technique is simpler than marching-cubes and does not have its nasty ambiguity configurations, leading to simpler iso-surfaces generation. We advocate the use of tetra-cubes for its simplicity of implementaion and generality.
