[vtkusers] Remesh vtkpolydata

[siqi chen]

This is a classical problem in shape modeling and it is still an active
research problem. I am not aware of any vtk implementations.
I would recommend the following recently published survey paper:

"Statistical shape models for 3D medical image segmentation: A review "
