An update!

For the last 2 week I've been researching for a way to do some motion capture for the little 3D short film. Although is still a long way to go, but so far, I've been making small progresses. After searching for a not so expensive system, I came up with the Brekel Kinect (Free). In short, allows you to connect your Xbox Kinect and link it to MotionBuilder for real life motion capture. This was my very first test, not everything seems to be fluid as I haven't calibrated the software yet.

There's an Ipi solution and it looks better, but I would have to invest some money on it. Will try it later and see if that is worth it.
