This program looks interesting, apparently there was a demo about around a year ago, i tried looking for alternative programs that do the same thing but couldnt find any. Does any one know of any at all?
VisualMarker is a fast and easy to use utility for converting 2D marker positions to skeletal based models. The real-time calculations provide full visual control at any stage of the capturing process. VisualMarker can use up to four video streams for motion capture, and does not require special camera calibration or large specialized room placement. VisualMarker supports not only the industry standard BioVision BVH format but also a native format for game development
