[Paraview] Applying a texture to a sphere

[Michael Jackson]

Thank you. That did the trick. I was able to apple the image as a 
texture to a sphere. So many options in the properties panel I was just 
not seeing the specific option that I needed. Forgot about the search 
panel. Duh.

That image got me pretty close to what I wanted, now to figure out how 
to generate actual texture coordinates, or color a sphere via each cell.

Thanks for the help
