[vtkusers] vtkMarchingCubes

Now I converted my 8bit buffer to a 16bit buffer and sliced it, then passed 
it to vtkVolume16Reader and then to marching cubes, and I got the volume.  
But my result is not smooth at all, I set the 
MarchingCube->ComputeNormalsOn(); and still the result is not smooth.
Is there any filter I can use to smooth the resulting output from marching 
Thanks in advance


P.S Thanks james;
