[vtkusers] How to perform intersection tests

        What is the best way to perform intersection tests, so that  
the tests are fast and computationally inexpensive. I have two 3D  
spherical glyphs and I want to specify a 3D translucent bounding  
sphere over the 3D glyph.

If the bounding spheres of the two glyphs intersect each other, I want  
to display a message.

Best regards,
