Comparison of triangulated mesh and DEM grid formats of second mandibular molar tooth surfaces for species <i>Cercocebus atys</i> and <i>Theropithecus gelada</i>.

<p>Teeth are presented in oblique perspective, with distal and buccal aspects toward bottom-right and bottom-left respectively. Color scaling reflects elevation. Triangulated mesh data is used for calculation of 3D-OPCR and DEM grid data is used for calculation of DEM-OPCR. Triangulated mesh data used here represents molar surface at a relatively finer resolution compared to DEM data.
