hm, maybe I am wrong, but it appears you have only taken direct reflections into account. This is appropriate for small wave lenghts only since bass frequencies to not "see" smaller objects as obstacles but go aorund them easily. Is that calculated?
yes, actually. i recent did this with success, however it takes a loooooong time to generate an impulse response. i mean relatively long, 8-10 minutes. basically I made a ripple tank in the same manner as paul falstad's ripple tank (www.falstad.com/ripple/) and set the source to emit a white noise burst for a small number of frames, then i created a 'mic' to capture the height/brightness data at some arbitrary point. obviously added various walls and curves to the environment. once the data was recorded to a text file i used matlab to convert the samples into a wav file, and then logic pro x for easy convolution. this is a pretty rough way of doing it but it did work. the impulse responses always sounded sort of like you were underwater.
This is so awesome! :D
What software did you use to create this video?

Could this be used to generate an artificial impulse response from any point in the room for convolution reverb??

How can I make this kind of simulation using my own 2d plane?
