Hi everyone, I'm new to Rhino and Grasshopper but I would like to use them to do an acoustical analysis of a performance hall I am working on for class (student here). I have the room modeled in rhino 5 and I've been looking around for how to do a ray tracing study on the space using grasshopper but the internet is a big place where nothing is ever actually explained. How does one set up a ray trace that will show reflections off all of the surfaces? I would appreciate it if anyone can get me started in the right direction.
