Hi,
	I'm starting on a ray tracing project but I'm having one problem.
I don't know how to convert the intensity calculations from the reflection
model into the appropriate RGB values for display. I know it has something
to do with integrating certain functions to get the XYZ values and then
transforming these to the RGB space via a matrix multiplication. I need 
more info about the functions to be integrated and more detail on determining
the transformation matrix. If anyone knows something on this topic please
respond! I'm using a RAMTEK capable of 1024 simultaneous colors determined 
by an 8-bit value for each component of RGB.

					Thanks,
					Jeff Faust
