How 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.

- kabla 13y agoThe algorithm calculates all possible specular reflections up to some order. I really don't think I can explain it any better than this paper: https://mediatech.aalto.fi/~samuli/publications/laine2009aa_paper.pdf https://mediatech.aalto.fi/~samuli/publications/laine2009aa_...
- cocoflunchy 13y agoThanks, I'm going to read up on this.

- sp332 13y agoIt 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.
