Ray Tracing for acoustic analysis

Hi everyone,

I’m looking to write a ray tracer in Ruby that can be used for acoustic
analysis.

Can anyone give me any pointers?

Cheers,
Dan

A bit of an open question! I have written ray tracers for image
generation (computer graphics) but I expect the same ideas and
techniques can be applied to acoustic analysis. There are many good
books on ray tracing in computer graphics (An introduction to ray
tracing by Glassner) and SIGGRAPH papers. Most of the execution time
goes in finding intersections and there are many different acceleration
data structures you can use to speed up the 3D spatial search. I
wouldn’t use Ruby for the intersection search (other than prototyping)
simply because of its performance.

Dave.
