  1. The radiation module  Current status 

  2. Substitute for heat conduction

  3. Useful units, etc

  4. Number of directions, etc

  5. Number of directions, etc 1 ray means just 1 direction  Useful for volume rendering

  6. Volume rendering • Want to see everything in the volume • Forground should cover background stuff • More than just one field • Different colors… Axel Brandenburg: Lightsabers
