- Abstract
- We describe a method to decompose a cube with trilinear interpolation into a set of tetrahedra with linear interpolation, where isosurface topology is preserved during decomposition for all isovalues. This method is useful for converting from a rectilinear grid into a tetrahedral grid in scalar data with topological correctness. We apply our method to topologically and geometrically accurate isosurface extraction.
