I'm building a raytracing engine to get an approximation of the impulse response of a room, but the problem is that I don't really understand what to do after the ray tracing.
After I get all the reflections that collide with the receiver, I get all the rays with their acoustic energy and collisions time. But how do I turn this into an actual impulse response that i can hear using convolution. I was thinking in using a three band eq and turn the reflection energy into intensity, to set parameters for the eq, then send an impulse through the filter and do this for each ray; and finally sum all the impulse responses at their correct times. Please help, I'm not sure if the method I'm going to use is correct.
