Hey, I'm workin on that project as well.

We thougt of tracking via video only and want to use 2 Cameras. From that data we need to figure out the person's 3D coordinates in the prepared room.
Do you believe pd can handle that?
I've found some patches which track motion in 2D (gridflow) but our project seems far more complex.

Once we get the position and can follow the probant's motion, the sound-calculating shouldn't be too complicated.

best regards
from Bremen
