Abstract
Foldovers (i.e., folding of triangles in a 3D mesh) are artifacts that cause problems for morphing. Mesh morphing
uses vertex correspondences among the source and the target mesh to define the morphing path. Although there
exist techniques for making a foldover-free mesh morphing, identification and correction of foldovers in existing
correspondences is still an unsolved issue.
This paper proposes a new technique for the identification and resolution of foldovers for mesh morphing using
predefined 3D mesh correspondences. The technique is evaluated on several different meshes with given correspondences.
The mesh examples comprise both real medical data and synthetically deformed meshes. We also
present various possible usage scenarios of the new algorithm, showing its benefit for the analysis and comparison
of mesh correspondences with respect to foldover problems.
