Detailed Description

Tetrahedral mesh generation from a multiclass label image.

tgstkImageToMeshFilter generates a tetrahedral mesh from a label image with multiple subdomains using 3D restricted Delaunay triangulation with a protecting phase to guarantee an accurate representation of the subdomain boundaries. The filter is based on the CGAL library.
