Geometry compression of tetrahedral meshes using optimized prediction

In this paper we propose a novel geometry compression technique for volumetric datasets represented as tetrahedral meshes. We focus on a commonly used technique for predicting vertex geometries via a fiipping operation using an extension of the parallelogram rule. We demonstrate that the efficiency of the fiipping operation is dependent on the order in which tetrahedra are traversed and vertices are predicted accordingly. We formulate the …
