2. Physics Shaders

 This shader library provides a collection of shaders that implement caustics, global illumination and other functions that support  physical correctness.

Before any shader in the physics shader library can be used, it must be attached to the mental ray rendering software using a statement link "physics.so", and the shaders must be declared with the statement $include <physics.mi>. Declarations are given in mi format, as described in chapter [*] on page [*]. Here is the summary:

group shader page

Light physical_light [*]
Material dgs_material [*]
  dielectric_material [*]
Photon dgs_material_photon [*]
  dielectric_material_photon [*]
Participating Media parti_volume [*]
  transmat [*]
