Approximate Rigid Interpolation for Negating Tetrahdral Meshes

Abstract

Approximate Rigid Interpolation for tetrahedral meshes requires meshes without negating tetrahedrons. However, it is difficult to construct such meshes and this is a problem for rigid interpolation. We present a method for rigid interpolation for tetrahedral meshes with negating tetrahedrons. Our method computes pseudo rotation function for negating tetrahedrons from neighbor tetrahedrons. This enables us to compute rigid interpolation for tetrahedral meshes with negating tetrahedrons.
