Abstract

Physically plausible illumination in real-time is oftenachieved using approximations. Recent methods approximateglobal illumination in the screen space by exploitingthe capabilities of modern graphics cards. Two of thesetechniques, screen-space ambient occlusion and screenspacedirectional occlusion, are described in this work.Screen-space directional occlusion is a generalized versionof screen-space ambient occlusion. It supports one indirectbounce of diffuse light and depends on the direction of incominglight. The main goal of this project is to furtherexperiment with these methods and improve them. Fora uniform distribution of the sampling points, the Haltonsequence is used. In order to reduce the noise, geometryawarebilateral filtering is presented. Methods are furthersped up by computing them in a lower resolution, and theyare restored to full resolution using joint bilateral upsamplingin order to create the final image.
