[vtkusers] vtkContourFilter produces inconstistent meshes

[Hendrik Belitz]

Hello,

maybe you could assist me in solving a little problem. I need to extract a 
surface mesh from a given binary volume dataset. The volume data is 
topologically simple (no holes or gaps). But by extracting it with  the 
vtkContourFilter, some holes appear in the resulting mesh. 

Do you know any other ready-to-use implementations or fixups for isosurface 
generation which solve this problem? Or are you able to point me to some 
repair algorithm to fix the holes in the resulting mesh?
