Fan 'Andy' Zhang, The Chinese University of Hong Kong "Parallel-Split 
Shadow Maps on Programmable GPUs"

Friday 4th December 2009, 2-3pm GMT Room 1.10, Kilburn Building The 
University of Manchester

Like any other visual effect in real-time applications, practical shadow 
algorithms should allow developers to trade cost and quality. As a 
popular real-time shadowing technique, Shadow Mapping however cannot 
achieve this goal in complicated scenes, because it does not adequately 
trade performance cost for quality. Parallel-Split Shadow Maps (PSSMs) 
are one of the most promising shadow mapping techniques to achieve this 
goal. However, without using hardware acceleration, the performance drop 
caused by multiple rendering passes prevents this technique from being 
extensively used in mass-market applications. In this talk, we show how 
to take advantage of modern Graphics Processing Units (GPUs) to improve 
performance in PSSMs. Furthermore, a few practical issues when 
integrating PSSMs into real games are also discussed.
