Hi Flory,<br><br>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.<br>

Hello,<br>
I was wondering if the vtkMarchingCubes filter preserves the<br>
coordinates of the points - do the points on the triangulated surface have<br>
the same coordinates as in the initial image or the units or distances are<br>
changed?<br>
Thanks a lot!<br>
Flory<br>
