Hello out there:

     I have developed a ray tracing program, and am at the stage
of adding acceleration code to it.  I have bounding volumes and
shadow caching.  From my research ray classification seems best, is
this so?  I want to implement the algorithms discused in "Fast Ray
Tracing by Ray Classification" by James Arvo and David Kirk
SIGGRAPH Proceedings 1987.  Has anybody implemented these algorithms?
What time improvements if you seen?  
     Any psudocode, source code information on expanding these algorithms
would be greatly appreciated.

     Please send me ANY information that might help.
 
     Thank You -- Eric J. Chet -- chet@cis.ohio-state.edu
