[vtkusers] Fill closed surface with voxels.

[Hendrik Belitz]

Hi Vladimir,

since I guess that this is essentially the same problem Achim Poll required a solution for a day before, I'll give you the same answer:

With high probability, this answer is still valid:

I use vtkPolyDataToImageStencil for myself with good results to "voxelize" polydata meshes. Even more decent results could be obtained by using an external library, like object voxelization by filterung for example( http://www.viskom.oeaw.ac.at/~milos/ ), with the only drawback that you need to convert your data by yourself into the appropiate formats.


Regards
 Hendrik
