[vtkusers] Cutting non-convex surfaces

[Dan Asimov]

Hi,

I've a non-convex shape that I need to cut through. The user draws two
contours parallel X-Y plane, then I generate the surface using
vtkVoxelContoursToSurfaceFilter. However, when I cut with a plane parallel
to x-y using vtkCutter, the order of the points of the generated result is
messed up (pls see the attachments). I tried to run many filters on this
result to get the expected one without success.

Can anyone help me on how to cut this surface to get the expected result?

Thanks,
Dan
