Hi Guys. I'm a mocap guy from down under. I like what I have read about Optitrack. I would like to know more about how you achive the calibration of multiple cameras to create 3d point data, or is this done in a post calculation. I too would like to see your system come together and use it. The big boys are way to expensive, and it still takes alot of work to get the mocap on screen after $250,000 or so.
Cheers
