Hello,thanks for your contribution ! I have learned pyroomacoustics for a while. Lines 2206 to 2220 https://github.com/LCAV/pyroomacoustics/blob/0ccf8ae06f818f00a43a712038607e6744c13d08/pyroomacoustics/room.py#L2206 and lines 2277 to 2301 https://github.com/LCAV/pyroomacoustics/blob/0ccf8ae06f818f00a43a712038607e6744c13d08/pyroomacoustics/room.py#L2277 of the room.py are related to ray tracing code,I would like to know whether there are literatures or other references for the ray tracing method.How did you write the rt_needed code? Thanks a lot.

Hi, this is a good question indeed, and the documentation should be clearer.

The simulator is heavily based upon Dirk Schroeder's PhD thesis:

Dirk Schroeder, Physically based real-time auralization of interactive virtual environments, 2011.

I have also found the wayverb documentation to be very detailed and useful. It is a different project implementing a similar simulator.
