3 3D unstructured tetrahedral mesh

4

5 Approach: reduce mesh to a handful of elements interaction model is compare/contrast compare geometry, compare error level visual comparison info: color, shape haptic comparison info: texture provide analytic information in a Closeup view what matters: size, shape, orientation of tet. and its neighbors
