Shadow mapping (Williams 1978) has been used extensively in 3D games and applications for producing shadowing effects. However, shadow mapping has inherent aliasing problems, so using standard shadow mapping is not enough to produce high-quality shadow rendering in complex and large-scale scenes. In this chapter we present an advanced shadow-mapping technique that produces antialiased and real-time shadows for large-scale environments. We also show the implementation details of our technique on modern programmable GPUs.
