Wow this is very cool. I am sorry to hijack this thread to ask a related question. Does anyone know if libraries or programs exist that can model light rays in 3D for objects without circular base, for instance for modelling head lamps on cars and such?

I vaguely remember reading about a job that required Open Cascade, to do this (designing optics for automotive applications), if that's what you're seeking. Company was called DBM Reflex in Laval, QC I'm sure other tools (ie. game engines) will also allow you to model all types of optical effects.

  Game engines generally aren't able to model optical phenomena very well, but some rendering engines that use unbiased path tracing, especially if using spectral colours, can do so very well, to the point where they can be used in physics research. Some are guaranteed to tend towards the physically correct solution as long as the material functions are correct.

I guess there are already such addons for Blender app, but I'm not sure what exactly you need, so it would be better to ask such question in Blender Community places[0]. Take a look on those two.[1,2] [0] https://www.blender.org/community/ https://www.blender.org/community/ [1] https://github.com/CodeFHD/OptiCore https://github.com/CodeFHD/OptiCore [2] https://github.com/TobiasNils/Ray-Optics-Analyzer https://github.com/TobiasNils/Ray-Optics-Analyzer

The absolute best tool for this is LuxRender, which comes with a Blender extension. It is quite accurate. Otherwise, Mitsuba also works, and the new version even provides differentiable rendering.
