Hi all, I'm working on a project that procedurally generates a series of spaces (think tunnels and caverns) and would really like reverb that can match the player's position. I'd like more than just a good overall reverb for the entire space, or even a few open/closed spaces to choose from.

Ideally, I'd like to have the program analyze the surrounding space and create a convolution impulse response in realtime. The space is rather low-fi (pixelated so the # of data points we're talking about is very small, not like trying to accurately model every crevice and surface of a real cave).

I found this interesting link that suggests this would be possible:

But there are really no tech details about the "raycasting" method used. Any ideas?
