It can also be used in a ray tracer to help predict where caustics will
occur on a surface allowing the renderer to concentrate samples in those
areas. I'm told that SoftImage's renderer uses that technique.

There is a photon map patch, at www.nathan.kopp.com, perhaps it is what you are
after.

My understanding is, this was the method used to study optics before what we
call ray tracing was developed.

VERY computationally intensive, since you don't know if a light source's rays
are going to hit the camera or not. You end up with lots of rays that don't
get seen.
