Color rendering indices in global illumination methods
Human perception of material colors depends heavily on the nature of the light sources that are used for illumination. One and the same object can cause highly different color impr...

Real time volumetric shadows using polygonal light volumes
This paper presents a more efficient way of computing single scattering effects in homogeneous participating media for real-time purposes than the currently popular ray-marching b...

A unified framework for scene illuminant estimation
Most illuminant estimation algorithms work with the assumption of one specific type of the light source (e.g. point light source or directional light source). This assumption brin...

Bitmask Soft Shadows
Recently, several real-time soft shadow algorithms have been introduced which all compute a single shadow map and use its texels to obtain a discrete scene representation. The res...

Rendering Soft Shadows using Multilayered Shadow Fins
Generating soft shadows in real time is difficult. Exact methods (such as ray tracing, and multiple light source simulation) are too slow, while approximate methods often overesti...

Splatting with Shadows
In this paper we describe an efficient approach to add shadows to volumetric scenes. The light emitted by the lightsource is properly attenuated by the intervening volumetric struc...

Between umbra and penumbra
Computing shadow boundaries is a difficult problem in the case of non-point light sources. A point is in the umbra if it does not see any part of any light source; it is in full l...

Design and simulation of opera lighting and projection effects
A major problem challenging opera designers is the inability to coordinate lighting, projection systems, and set designs in the preliminary planning phase. New computer graphics t...

Soft Shadow Maps for Linear Lights
Soft shadows and penumbra regions generated by extended light sources such as linear and area lights are visual effects that significantly contribute to the realism of a scene. In ...
