Parallel-split shadow maps for large-scale virtual environments
Shadowing effects dramatically enhance the realism of virtual environments by providing useful visual cues. Shadow mapping is an efficient algorithm for real-time shadow renderin...

Quality scalability of soft shadow mapping
Recently, several soft shadow mapping algorithms have been introduced which extract micro-occluders from a shadow map and backproject them on the light source to approximately det...

Soft Shadow Maps: Efficient Sampling of Light Source Visibility
Shadows, particularly soft shadows, play an important role in the visual perception of a scene by providing visual cues about the shape and position of objects. Several recent alg...

Practical logarithmic rasterization for low-error shadow maps
Logarithmic shadow maps can deliver the same quality as competing shadow map algorithms with substantially less storage and bandwidth. We show how current GPU architectures can be...

Efficient Shadows for Sampled Environment Maps
This paper addresses the problem of efficiently calculating shadows from environment maps in the context of ray-tracing. Since accurate rendering of shadows from environment maps ...
