[vtkusers] multiple material marching cubes

[Prashanth]

All,
Does VTK have an implementation of the multiple material marching cubes 
algorithm (International Journal of Numerical Methods in Engineering 
2003; 58:189–207) ? By multiple material marching cubes, I mean creating 
contiguous 3D surfaces for as many materials(iso-surfaces) requested 
within a single sweep of an image volume.
Thanks
Prashanth
