Approximate ambient occlusion for dynamic scenes using the GPU

Natural scenes contain large amounts of geometry, such as hundreds of thousands or even millions of tree leaves and grass blades. Subtle lighting effects present in such environments usually include a significant amount of occlusion effects and lighting ...

Real-time rendering can benefit from global illumination methods to make the 3D environments look more convincing and lifelike. On the other hand, the conventional global illumination algorithms for the estimation of the diffuse surface interreflection ...

Ambient occlusion is a shading method which approximates the global illumination by taking into account attenuation of light due to occlusion[Christensen 2002; Sergey et al. 1998; Andrei et al. 2003]. Screen-space ambient occlusion is a scene-...
