Abstract

This paper presents two algorithms that enhance the existing techniques for screen space shadowing and deliver more appealing visual results. The first solution, called Spatial Depth Buffer Multi-sampling (SDBMS), uses higher resolution depth buffers for multi sampling. The second algorithm is called Multipass Occlusion Testing (MPOT) and uses multi pass sampling with variable step sizes while ray marching.

Screen-space bias compensation for interactive high-quality global illumination with virtual point lights
I3D '11: Symposium on Interactive 3D Graphics and Games

In this paper we present a method that targets high-quality global illumination at interactive frame rates. As many techniques in this context, our method is based on instant radiosity, which represents the indirect illumination in a scene with a set of ...
The alchemy screen-space ambient obscurance algorithm
HPG '11: Proceedings of the ACM SIGGRAPH Symposium on High Performance Graphics

Ambient obscurance (AO) produces perceptually important illumination effects such as darkened corners, cracks, and wrinkles; proximity darkening; and contact shadows. We present the AO algorithm from the Alchemy engine used at Vicarious Visions in ...
Screen Space Anisotropic Blurred Soft Shadows by Efficient Separable Filtering Method
CW '13: Proceedings of the 2013 International Conference on Cyberworlds

Shadow mapping is an efficient method to generate shadows in real time computer graphics and has broad variations from hard to soft shadow synthesis. Soft shadowing based on shadow mapping is a blurring technique on a shadow map or on screen space. ...
