This is an image of an actor, Kevin J. Ryan, that I motion captured performing some fight sequences (with my classmate, John Helton) in the fall semester. At the time, the footage was shot as a test, but I now plan to include it in the final film (it's the fight between Sam and Manoj, my secondary characters).
The markers are very reflective and appear to glow because of the camera flash. Note that the fingers are not mocapped and need to be animated by hand.
(Btw, Kevin's a great actor to work with, and I highly recommend him for both mocap and live-action shoots).
