Computing the antipenumbra of an area light source
We define the antiumbra and the antipenumbra of a convex area light source shining through a sequence of convex areal holes in three dimensions. The antiumbra is the volume from w...

Estimation of the Size and Location of Multiple Area Light Sources
Most illuminant estimation algorithms worked on point light sources or directional light sources. Little attempt has been made, however, to estimate area light sources. In this pa...

Real-time Computation of Area Shadows - A Geometrical Algorithm
The computation of soft shadows created by area light sources is a well-known problem in computer graphics. Due to the complexity of the problem, soft shadows commonly are generat...

A fast shadow algorithm for area light sources using backprojection
The fast identification of shadow regions due to area light sources is necessary for realistic rendering and for discontinuity meshing for global illumination. A new shadow-determ...

Incremental Updates to Scenes Illuminated by Area Light Sources
Abstract: An object space algorithm for computing shadows in dynamic scenes illuminated by area light sources is presented. A mesh with the shadow boundaries as well as other disco...
