Abstract

Virtual studios typically use a layering method to achieve
occlusion. A virtual object can be manually set in the foreground or
background layer by a human controller, allowing it to appear in front of
or behind an actor. Single point actor tracking systems have been used in
virtual studios to automate occlusions. However, the suitability of single
point tracking diminishes when considering more ambitious applications
of an interactive virtual studio. As interaction often occurs at the extremities of the actor's body, the automated occlusion ordered by single point tracking is insuffcient and multiple-point actor tracking is justified. We describe ongoing work towards an automatic occlusion system based on multiple-point skeletal tracking that is compatible with existing virtual studios. We define a set of occlusions required in the virtual studio; describe methods for achieving them; and present our preliminary results.
