Bodylab is a virtual reality system for creating full-body virtual reality avatars. It provides anatomically realistic mannequins as canvases, which can be painted and textured, sculpted and deformed, adorned with objects and animated with particle effects. The artist can work from a first or third person perspective, and variety of interaction modalities are made available. To assess the system, we invite costume designers and theatrical artists to provide expert reviews. We also describe the use of Bodylab in a live dance performance. We believe Bodylab to be the first virtual reality tool for in virtuo painting and sculpting of full-body avatars.
