Role and delivery

Development of software projecting mapped imagery ONTO a performer’s body for the A2H music video. The silhouette is tracked live by an Asus Xtion depth camera and the projected image is registered to it frame by frame, in C++ with libCinder. Projecting onto a moving body is a registration problem: the camera gives a silhouette, the projector must lay an image onto it, and the two devices do not see from the same point. They have to be calibrated against each other, then kept aligned despite the performer’s movement — otherwise the light spills onto the set.
