Abstract

This paper proposes a method of interactive virtual camera control in 3D character animation authoring. This method allows a novice user to interactively create a 3D character animation by recommending appropriate distance and orientation for a virtual camera based on the Grammar of the Film Language. We conducted an experimental evaluation in which 18 university students created 3D character animations using the Digital Movie Director (DMD) system with this method. The results showed improvement in the efficiency of setting the virtual camera, as well as in overall creation efficiency. Time spent writing dialogue increased, suggesting more time was available for creative thinking. The value of recall and precision were 0.77 and 0.84, respectively, for users who employed virtual camera settings covered by the method. Moreover, the ratio of shots that violated the Grammar decreased.
