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 offered by single point tracking is insufficient 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.
