In this paper, we consider accelerated rendering of high quality walkthrough animation sequences along predefined paths. To improve rendering performance we use a combination of: a hybrid ray tracing and Image-Based Rendering (IBR) technique, and a novel perception-based antialiasing technique. In our rendering solution we derive as many pixels as possible using inexpensive IBR techniques without affecting the animation quality. A perception-based spatiotemporal Animation Quality Metric (AQM) is used to automatically guide such a hybrid rendering. The Image Flow (IF) obtained as a by-product of the IBR computation is an integral part of the AQM. The final animation quality is enhanced by an efficient spatiotemporal antialiasing, which utilizes the IF to perform a motion-compensated filtering. The filter parameters have been tuned using the AQM predictions of animation quality as perceived by the human observer. These parameters adapt locally to the visual pattern velocity.
