[vtkusers] Question about surface generation

[Krista Lam]

Hello,

I have a stack of image slices that I import them using image reader
then generate the surface by marching cubes. The surface is fine.

Then I have to deform the surface, so I change the coordinations of the
points on the surface:
surface_polydata->GetPoints()->SetPoint(i, xyz)

After that, the resulting surface has "holes" on it. What can I do to
solve that problem? Please help. Thanks.

Best Regards,
Krista
