PPT-A New Technique for Real-Time Motion Blur Rendering

Steven Lu Overview Significance of realtime motion blur rendering Useful for what Slow performance of traditional methods Some of the modern more efficient methods have problems too A new method is presented . A static rendering of the scene is inset in the low er right and closeups are shown in be Strati64257ed sampling in b is very noisy at this low sample count Multidimensional Adaptive Sampling Hachisuka et al 2008 in c performs much better but still Fig.1.Motionestimationanddeblurringofharmonicrotationusingourapproach.Thispaperaddressestwofundamentalproblemswhenusingthe utteredshutter:1)howtoapplytheFStohandleabroaderclassofmotionsand2)howtoautom efficient rendering path for visible replicated objects. The key component to realize this is an efficient dynamic hardware instancing implementation that takes advantage of temporal coherence and use Shengyang Dai . and. Ying Wu.
