Bent Normals and Cones in Screen-space
(The Eurographics Association, 2011)
Ambient occlusion (AO) is a popular technique for real-time as well as offline rendering. One of its benefits is a gain in efficiency due to the fact that occlusion and shading are decoupled which results in an average ...
View-independent Environment Maps
(The Eurographics Association, 1998)
Environment maps are widely used for approximating reflections in hardware-accelerated rendering applications. Unfortunately, the parameterizations for environment maps used in today s graphics hardware severely undersample ...
Real-Time Bump Map Synthesis
(The Eurographics Association, 2001)
In this paper we present a method that automatically synthesizes bump maps at arbitrary levels of detail in real-time. The only input data we require is a normal density function; the bump map is generated according to ...
