[vtkusers] Marching Cubes speedup ?

[Will Schroeder]

Hi Nils-

Make sure that you are actually running vtkMarchingCubes with normal 
generation on. If you use vtkContourFilter you will not necessarily run 
marching cubes unless you run with patented classes enabled.

To use minimal memory, use vtkSliceCubes, which keeps only three slices of 
data in memory at any given time.

Also try running Kitware's synchronized templates. We've seen performance 
improvement of up to 3x in some cases.

In any case, in commercial application you will want to license from the 
patent holder.
