(LaTeX) Abstract:

In this paper we present several methods that can greatly improve
image quality when using the shadow mapping algorithm.
Shadow artifacts introduced by shadow mapping
are mainly due to low resolution shadow maps and/or the limited
numerical precision used when performing the shadow test.
These problems especially arise when the light source's viewing
frustum, from which the shadow map is generated, is not adjusted
to the actual camera view.
We show how a tight fitting frustum can be computed such that
the shadow mapping algorithm concentrates on the visible parts of the
scene and takes advantage of nearly the full available precision.
Furthermore, we recommend uniformly spaced depth values
in contrast to perspectively spaced depths in order to equally sample
the scene seen from the light source.
