Detailed Description

class shapeworks::MeshWarper;

This class implements mesh warping based on correspondence particles. Correspondence points are embedded into the mesh as new vertices (traingles split). Then a biharmonic deformation is used to warp the mesh to new sets of correspondence particles.

It can optionally be used to warp landmarks along with the mesh by embedding them as vertices
