vtkFillHolesFilter wrong normal direction
The vtkFillHolesFilter
will create triangles with wrong normal/index order
e.g. the new filled triangles have a opposite direction/normal:
These triangles/vertexes cannot be fixed by simplify compute vertex/triangle normals.
I have tried some similar filters in other libs(e.g. MeshLab/MeshFix), they seems have no such a problem.
