[vtkusers] Scalar interpolation

[Brian Curtis]

Hi,

I'm looking for an example that does this or a few examples that show 
the proper way to do this.

I'm not sure how to understand vtkProbeFilter from 
http://www.vtk.org/doc/nightly/html/classvtkProbeFilter.html and what 
part of it will do the work I need.

vtkProbeFilter->Probe requires three vtkDataSet but how do I get my 
points into a dataset?

Thanks for your help,
~Brian
