Here's a video of our attempt to remake the implementation of RVO (made by Stephen J. Guy, et al. http://gamma.cs.unc.edu/RVO2/).
The movement of the agents are working and most of them seem to be moving towards the opposite side of the circle (as specified as the goal for the agent). However, the agents doesn't seem to be avoiding each other nor do they change direction during the simulation, which they should do at some point.
But the simulation does run at a reasonable fps, so the computations aren't too heavy on the CPU.
