 Abstract: Soft shadows and penumbra regions generated by extended light sources such as
linear and
area lights are visual effects that significantly con-tribute to the
realism of a scene. In interactive
applications, shadow computations are mostly performed by either the
shadow volume or the shadow map
algorithm. Variants of these methods for soft shadows exist, but they
require a significant number of
samples on the light source, thereby dramatically increasing rendering
times.\\In this paper we present
a modification to the shadow map algorithm that allows us to render soft
shadows for linear light
sources of a high visual fidelity with a very small number of light
source samples. This algorithm is
well suited for both software and hardware rendering.
