Yes, because point_data represents attributes associated with the points. The scalars/vectors/tensors are therefore independent of the points. You can of course achieve this by using the scalars to modify the points using a warp filter. For example you could setup the points to be planar on the x-y plane and set the scalar values but instead you'd have to do: src = mlab.pipeline.add_dataset(poly_data) surf = mlab.pipeline.surface(mlab.pipeline.warp_scalar(src)) Then your approach may work. cheers, Prabhu ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
