This demo is an extension of the testing environment used in my capstone project, which was about optimizing collision detection. The simulator does not use Unity's PhysX physics engine, rather it uses hand-made physics better suited to working with the algorithms involved. I added the GUI controls for this demo. There is a zipped file of the full Unity project on github, as well as another repository for just the code. You can also read the paper detailing the research on collision detection algorithms.

Directions:

1. The Algorithm Selector chooses which collision detction algorithm is used. The default algorithm is currently 'Simple', be sure to try out one of the others. Sweep and Prune is the best performer in most cases and is the most robust.

2. Try messing with the configurations and notice when performance becomes unsatisfactory.
