Shadows are the dark companions of lights, and although both can exist on their
own, they shouldn't exist without each other in games. Achieving good visual
results in rendering shadows is considered one of the particularly dicult tasks
of graphics programmers.
For this edition of GPU Pro, we accepted only one article for this section. The
article “Real-Time Deep Shadow Maps” represents the state of the art in real-
time deep shadow maps. The article covers an implementation that only requires
a single rendering pass from the light without introducing any approximations. It
covers a novel lookup scheme that exploits spatial coherence for ecient filtering
of deep shadow maps.
