Group Assignment 1 Image Sources for Acoustic Simulations ART CONTEST RESULTS
In this assignment, students created an interactive application in Javascript to simulate the acoustics of virtual 3D environments using image sources ray tracing. This resulted in the ability to model echoes in a variety of different environments.
In some of the examples below, you can click to view the scenes interactively. This is simply for viewing; no acoustics will be provided to avoid posting solutions to problems that might be re-assigned in a future iteration of this course
"Our art submission depicts a tennis court. Our idea was that the receiver could model one
player, while the source models another. Enable transmission to see all the mistakes it is
possible to make by hitting in the net or out, and disable the transmission to see where not
to hit the ball (you don't want to hit it at right at the other player do you?!). Tennis is
tough, huh? There's an art to it."

Ellipsoidal Whisper Chamber
Most group did this task. I picked this submission to show this because of this group's lulzy sound choice (Selena Gomez "Round And Round" because of the roundness of the ellipsoid...heh...)
Notice in the videos below how the source (drawn in green so it will show out) is very far away, and when not on the foci, the sound is barely audible (you may have to turn up your speakers to hear it). But when moving to the foci, it suddenly sounds as if Selena is right next to me!
My head fighting superman with a throng of onlookers (go to the receiver's point of view to start with superman. Disable mesh edges to see my wonderful face details more clearly):
