Subtractive Shadows: A Flexible Framework for Shadow Level of Detail
Abstract. We explore the implications of reversing the process of shadow computation for real-time applications that model complex reflectance and lighting (such as that specified ...

The Soft Shadow Occlusion Camera
A fundamental challenge for existing shadow map based algorithms is dealing with partially illuminated surfaces. A conventional shadow map built with a pinhole camera only determi...

Application of the two-sided depth test to CSG rendering
Shadow mapping is a technique for doing real-time shadowing. Recent work has shown that shadow mapping hardware can be used as a second depth test in addition to the z-test. In th...

Generating perceptually-correct shadows for mixed reality
Even though shadows are important for photometric consistency in Mixed Reality (MR) [1]. When human cannot perceive the inconsistency of artificial shadows which are not physicall...

ShadowCuts: Photometric Stereo with Shadows
We present an algorithm for performing Lambertian photometric stereo in the presence of shadows. The algorithm has three novel features. First, a fast graph cuts based method is u...
