Abstract
Techniques are disclosed for interactive editing of virtual three-dimensional scenes. In the disclosed techniques, rendering is divided into (1) an interactive phase during which a user interactively edits a virtual scene while preview image frames are rendered using a modified ray tracing technique, and (2) a refinement phase during which full ray tracing is performed to show the user a final rendered image frame. The modified ray tracing technique may limit the number of bounces of light rays and/or the computations performed at each bounce, thereby reducing computational expense relative to a full ray tracing technique. Further, the modified ray tracing technique may be user-selectable and associated with a particular department within an animation studio.
