[vtkusers] More fine-grained vtkMarchingCubes

Hello Vladimir,

Did you pick the correct isovalue? You could try an isovalue in the 
center of the scalar range of your data.

If that doesn't help, you could process the output of the Marching Cubes 
with vtkSmoothPolyDataFilter.

Another option is to smooth your input data with vtkImageGaussianSmooth. 
Be aware that too much smoothing might change the topology of your data.

I use vtkMarchingCubes to extract a surface from a voxel data. Naturally,
I get a surface which looks like "stairs". Which parameter shall I change
to make each step of that "stairs" smaller (increasing their number, of
course), or bigger (decreasing their number)?
