I saw this image the other day in Jane and Mark Burry’s  excellent book The New Mathematics of Architecture and thought: “I can do that.  I don’t really know what it means, but let’s figure out a good story.”  Something about acoustic optimization, reverberation time, blah blah blah. 

With this solid methodology in place, and unencumbered by any real knowledge, I put together this little tool that works as a generalized one bounce raytracer.  Key to the construction of this family is this assumption of an ideal reflection of a ray.  That is, an incoming ray is perfectly reflected off a surface relative to a normal line from the surface.

  1. This is awesome.

    3 or more bounces would be ideal. Either way, my acoustical engineer will love this.
