| dc.description.abstract | The majority of computer graphics images are generated as part of a sequence of animation frames. The usual approach for producing these images is to render each frame as if it were a single, isolated image. A technique is described which exploits spatial-temporal coherence between frames to speed up the generation of a ray-traced animation sequence. The concept is that the information gained when ray-tracing a particular frame in a sequence may be used to speed up the generation of adjacent frames, reprojecting samples from one frame to the next. This approach promises significant savings when ray-tracing animations which have moving and rotating viewpoints, objects and/or light sources. The algorithm is tested on an animation with many reflective surfaces, yet it still attains up to 96% savings over full ray-tracing in terms of the number of rays cast. | en |
