Post-rendering 3D warping

Abstract

A pair of rendered images and tbek Z-buffers contain almost all of the information necessary tore-render from nearby viewpoints. For the small changes in viewpoint that occur in a fraction of a second, this information is sufficient for high quafity re-rendering with cost independent of scene complexity. Re-rendenng from previously computed views allows an order-of-magnitude increase in apparent frame rate over that provided by conventional rendering alone. It can also compensate for system latency in local or remote display.
