ABSTRACT
Reflection occlusion(RO) method can yield the self-occluded effect when using environment maps to produce a reflection scene. In most modern renderers the common approaches to achieve RO are the ray-trace method and the static reflection maps method. We propose screen-space reflection occlusion(SSRO) method to compute RO in screen-space like screen-space ambient occlusion in [Bavoil et al. 2008] and screen-space directional occlusion in [Ritschel et al. 2009]. Our different strategies for both calculating the occlusion value and sampling in the depth image enable SSRO to calculate RO in real-time and to deal with dynamic scenes, variational lighting environments and changing views.

Real-Time Volume-Based Ambient Occlusion
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 ...
Real-time reflection mapping with parallax
I3D '05: Proceedings of the 2005 symposium on Interactive 3D graphics and gamesWe present a novel algorithm to efficiently render accurate reflections on programmable graphics hardware. Our algorithm overcomes problems that commonly occur in environment mapping such as the lack of motion parallax and inaccuracies when objects are ...
Real-time accumulation of occlusion-based snow
This paper describes a technique to allow the real-time simulation of snowfall accumulation in a dynamic 3D environment. The implementation maps surface-bound accumulation buffers to each object in the scene, forming height-maps of accumulated snow ...
