[vtkusers] self intersecting surface mesh

[oka]

Dear users,

I extracted a surface shape from image data by
MarchingCube method and made it to triangle
surface mesh. It was decimated by vtkQuadricClustering.
When volume mesh was tried to make by gmsh,
It says Error: Self Intersecting surface mesh.
Can I correct the mesh by vtk to get a volume mesh ?

Bet regards,

Oka
