An Optimized Soft Shadow Volume Algorithm with Real-Time Performance
(The Eurographics Association, 2003)
In this paper, we present several optimizations to our previously presented soft shadow volume algorithm. Our optimizations include tighter wedges, heavily optimized pixel shader code for both rectangular and spherical ...
Interactive Rendering of Atmospheric Scattering Effects Using Graphics Hardware
(The Eurographics Association, 2002)
To create realistic images using computer graphics, an important element to consider is atmospheric scattering, that is, the phenomenon by which light is scattered by small particles in the air. This effect is the cause ...
SPAF: Sub-texel Precision Anisotropic Filtering
(The Eurographics Association, 2001)
Texture mapping is a technique which most effectively improves the realism of computer-generated scenes in 3D Graphics. Trilinear filtering of the mip-mapped textue has been popular as a texture filtering method but it ...
Low Latency Photon Mapping Using Block Hashing
(The Eurographics Association, 2002)
For hardware accelerated rendering, photon mapping is especially useful for simulating caustic lighting effects on non-Lambertian surfaces. However, an efficient hardware algorithm for the computation of the k nearest ...
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 ...
