[vtkusers] Diagnostic of Geometric errors in a Mesh(.stl etc)

[Cory Quammen]

You can use vtkFeatureEdges [1] to identify edges that a non-manifold.
Nothing I know of does self-intersection tests, but you could may do
this yourself with vtkTriangle::TrianglesIntersect() [2].

I'm not aware of anything that will fix these situations automatically.

HTH,
Cory
