Analytical motion blurred shadows
Abstract: A rendering framework supporting analytical visibility is extended with shadow mapping. Shadow maps containing analytical visibility data are used, leading to cases where both the projections to the shadow map and the depth tests can be time-dependent. For receivers that are static with respect to the camera, the depth tests are solved analytically over time. For dynamic receivers, point sampling is used. Problems arising from time-dependence, limited precision and necessary simplifications are investigated, and potential solutions are discussed.
