Claim 0:
1. A computer-implemented method for real-time shadow rendering using cached shadow maps and deferred shading, the method comprising, for at least each key frame of video output:
determining, by one or more processors, a viewpoint for a current key frame based on user input;
filtering, by the one or more processors, a texel of a frame-specific shadow map based on a dynamic mask wherein the texel is filtered, for a shadowed light, from a static shadow map and a dynamic shadow map or from the static shadow map only, based on the dynamic mask value for the texel; and
rendering, by the one or more processors, the current key frame based on the frame-specific shadow map and a deferred-shadow rendering algorithm.
