An accurate 3D visualization could have been a lot simpler than this. The actors are most likely modeled physically as simple cylinders; all the character animations are extraneous. And there's plenty of subtle effects in the seekers' vision cones, the reflective floor, the uneven box landscape outside, etc.
So, as tlb said, I'm curious if all of that was added for the public release, or if the researchers set it up while running the experiments. It seems like it would be fun.
