I never used Povray but intend to do it for some scientific purpose. Before
diving into the manual, I would like to know if I could solve this problem:
I would like to define a object by a refraction index distribution n =
n(x,y,z). Then I would like to illuminate the object by laser light and
observe the reflected light resulting from the index gradient in the
material and the interference of the coherent light.
Thankx,
Fabian
