[vtkusers] Marching cubes filter

[Sylvain Jaume]

Hi Flory,

Yes, vtkMarchingCubes will use the origin and spacing of the input image.
There is no units per se in VTK (mm, cm, inch,...). The vertices in the
Marching Cubes mesh will interpolate the voxel positions, so vertices and
voxels won't have exactly the same positions.

HTH,
Sylvain
