abstract = "We present several techniques that can drastically
improve shadow quality, when using the shadow mapping
algorithm. Visual artifacts like jagged shadow
boundaries or z-fighting are mainly due to insufficient
shadow map resolution during the shadow test and/or
limited numerical precision. We show how to compute a
tight light source viewing frustum, dependent on the
current camera setup, such that nearly the full shadow
map resolution is available. Furthermore, we recommend
linear distribution of depth values instead of
perspective depth values.",
