[vtkusers] Can VTK remove the internal part of a mesh

[Xiaoxu Wang]

Hi all,

    I have a mesh(PolyData) composed of multiple intersecting parts.
Can VTK
tell the intersection line of different parts? Can VTK remove the
internal
triangles of a mesh and only keep its surface?  Is there any way to
smooth
out the sharp angle around the intersection line? Is there any way to
remove
part of the mesh along the intersection line? Thanks in advance.
