[vtkusers] vtkContourFilter produces inconstistent meshes

[Toon Huysmans]

 Hi Hendrik,

 If you have a binary volume, i would use the vtkMarchingCubes filter.

 I am not sure, but it could be that vtkContourFilter uses vtkMarchingCubes
 underlying, so my suggestion would not work that case.

Greetings,

 Toon.
