[vtkusers] find out scalar values after surface reconstruction

[Pavel Schor]

Hi,
I need to view data from 3D surface scans. These data may have an
"imperfection" which is a scalar value.
So I wrote a python script, which uses SurfaceReconstructionFilter. It
works fin, but if input data have scalar values, this filter simply ignores
them. In case of geometrical imperfection it does not matter, since I  can
calculate scalar values at given point from its x,y,z coordinates.
But I have files with thickness imperfections, which have prescribed scalar
value at each point. My question is how to determine scalar values at
reconstructed surface? I tried vtkProbeFilter, but always got only zero
values.

Thanks
Pavel
