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.
