A new tetrahedral tesselation scheme for isosurface generation
The marching cubes algorithm is widely used to generate isosurfaces from a 3D scalar field. A major problem associated with it is the possibility of mismatch between adjacent surface elements, leading to holes on the surface. In this work, we propose using a tetrahedral tesselation of space which would eliminate this problem. Comparing with existing remedies of the marching cubes method which subdivide each cube into tetrahedra, the current tesselation is more regular and symmetric.
