In our test Scene, we have 2 objects moving towards each other. Once they collide, they go away from each other and, when they reach a given distance, they start to move back against each other again. You can simply check how the collision is the one doing the work by changing what it does on the callback function defined in core.cpp (void cb()).

Bruno was in charge of the test scene, callback system, and Sphere's implementation.

Karina was in charge of creating Sphere Manager and iSphere structure.
