Spatial-temporal antialiasing

摘要

A framework for discussing the motion blur image generationnprocess is formulated. Previous work is studied in the context of thisnframework. Due to the implicit assumptions on low temporal frequenciesnin most motion blur algorithms, issues involved in large screen spacenmovements and fast illumination changes in time have not been adequatelynaddressed so far. A new approach that does not make these assumptions isnintroduced to solve the spatial-temporal geometric and shading aliasingnproblems separately. Based on newly developed adaptive algorithms in thenspatial-temporal domain, an implementation of the new approach isndeveloped to efficiently deliver high-quality motion blurred images inngeneral computer graphics production environments
