Very insteresting project! I wonder if wearing a suit with different color for each limb could replace the use of reflective markers. The software should calculate the "bounding box" for each colored area and from that calculate the orientation of the limb. ( I know, I'm making things too easy!!! ; )  )

P.S.

I suggest DAZ, as reseller.
