[vtkusers] Mapping from float to int

[Ivan Dmitriev]

Hi people !

   I have a volume. After using vtkContourFilter I get a triangulated
surface. But resulution of the voxels is not equal 1, but something
like 0.72x0.72x1.9... Is there some method getting for given  vertex
its corresponding volume voxel ?

P.S.
   I know, that for getting volume voxel enough just divide vertex
   coordinates by given  voxel resolution, but in pipeline I also have a mesh smoothing
   filter, so it can move vertex "quite far" from original position...

   Thanks in advance
