[Paraview] Use existing texture map for 3D surface

[Olumide]

Hi Eric,

Thanks for the example. I've textured my very first sphere :)

I've taken another look at the VTK file format and I now realize that it 
is possible embed extra scalar (UV) <PointData> information in a VTK/VTP 
file (I'm a novice, but I'm learning).

I've got a mesh with texture coordinates, and I can modify my external 
VTP file writer to embed texture coordinates in my VTP file, so that the 
programmable filter extracts it. Is this the correct approach? And will 
the line:

Uarray = pdi.GetPointData().GetArray('U')

in your script extract U coordinates in the file?
