Re: Using beam tracing to calculate reflections in JavaScript
#2It really never ceases to amaze me the things you can do in JavaSCript. That's the kind of thing that up until a few years ago you'd be hesitant to do in Java. This is really cool stuff! I look forward to when we get full powered PC games done in JS. We're not there yet, I know - but it's little steps like this that'll get us there.

I agree, the speeds you can achieve with JavaScript are astounding. They are far superior to Python, it's a shame JS doesn't have that well of a support for scientific calculations.

#5How do you choose the angles at which you send the beams and the number of beams? It appears to be somewhat random, even though I'm sure it's not.

If anyone could list what support there is that'd be really interesting.

The algorithm calculates all possible specular reflections up to some order. I really don't think I can explain it any better than this paper:

It doesn't calculate all beams that originate from one point. It calculates only the beams which originate from one of the points and eventually reach the other point. It only looks random because the walls are placed at odd angles.
