Bill, the example does exactly what I need, thank you again.

Also I debugged the code behind vtkGeometryFilter and I now how it works.
(line 790, case VTK_VOXEL)

Also i tried the example to load 512^3 ushort volume and it consumed too
much memory (~900mb) and it crashed telling that further memory allocation
is not possible.

A sphere at resolution of 512^3 needs around 6*512*512=1.572.864
quadrilateral so I think better algorithms exists out there.

Bill, do you think that this can be done in VTK without writing a new filter
for it?

If so I have to write my own VTK filter based on the aboves and these:
