Accelerated pan and zoom for ray traced animation

Abstract

Ray tracing generates realistic images but is computationally intensive, especially when generating animation sequences. Many techniques have been developed, including exploitation of temporal coherence between successive frames to accelerate animation. This paper presents an efficient pan and zoom algorithm called the Panimation and RSVP algorithm, respectively. This new pan and zoom algorithm integrates the object animation acceleration technique of Jevans with the new pan and zoom algorithms and shows an order of magnitude performance improvement. Short animation sequences are presented to show our results.
