[vtkusers] mapping scalars onto geometry..

[K.R.Subramanian]

 I am trying to map scalar or vector functions onto geometry; for instance given the
gradient
magnitude of a volume, I would like to map that onto the polydata generated by Marching
Cubes..
- something like 3D texture mapping (I know vtk doesnt support 3D texture mapping)..

Do I need to go through each of the points(vertices) of the polydata, determine the
appropriate scalar value and then set it, or is there an easier way?

Thanks.
