The VX Lab at NC State studies how visual technologies affect human emotion, thinking and behavior. Our interests span computer graphics, human-computer interfaces, visualization, psychology and design. We post news from both ourselves and others here.
Morgan McGuire, Michael Mara, David LuebkeThis paper presents a set of architecture-aware performance and integration improvements for a recent screenspace ambient obscurance algorithm. These improvements collectively produce a 7 x performance increase at 2560 x1600, generalize the algorithm to both forward and deferred renderers, and eliminate the radius- and scene-dependence of the previous algorithm to provide a hard real-time guarantee of fixed execution time.
