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.
Abstract (Swedish)
En rastrerare med stöd för analytisk rörelseoskärpa integreras med shadow mapping. Shadow maps med analytisk synlighetsinformation används för detta, vilket leder till situationer där både projiceringarna till shadow map:en och djupjämförelserna kan vara tidsberoende. Djupjämförelserna utförs analytiskt över tiden för mottagare som är statiska i förhållande till kameran. För dynamiska mottagare används point sampling istället. Problem som uppstår på grund av tidsberoende, begränsad precision och nödvändiga förenklingar undersöks, och potentiella lösningar diskuteras.
