It seems to me that the particles landing on the left side of the bowl would
naturally be mostly deflected to the right side.

Good luck.
I have some vector and matrix code in C from when I wrote a simple
ray-tracer a few years ago.  It may not be "plug-and-play", but if you
would like a copy of it, let me know.
