Abstract

Virtual environments for rehearsal are useful because of their potential for distributed working and repeatability. During a rehearsal, actors’ avatars must represent the actions and intentions defined by both the script and the director. In live rehearsals, assessment by the director of the actors’ performance is by observation alone. However, in a virtual rehearsal environment it is possible to provide assistance in the appraisal process by analysing the avatars’ motion during the rehearsal because of the digital encoding. The system described here begins with observations of events that occur at the animation engine level and progressively abstracts and refines these observations to provide a high-level behaviour and performance assessment for the director to analyse in terms of high-level “artistic” concepts. This then allows the directions to be issued that will enhance the performance in the next rehearsal.
