abstract = "Shadow maps and shadow volumes are common techniques
for computing real-time shadows. We optimize the
performance of a hardware-accelerated shadow mapping
algorithm by rasterizing the light frustum into the
stencil buffer, in a manner similar to the shadow
volume algorithm. The pixel shader code that performs
shadow tests and illumination computations is applied
only to the pixels that are inside the light frustum.
We also use deferred shading to further limit the
operations to visible pixels. Our technique can be
easily plugged into existing applications, and is
especially useful for dynamic scenes that contain
several local light sources. In our test scenarios, the
overall frame rate was up 2.2 times higher than for our
comparison methods.",
