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 ...
Vertex-based Anisotropic Texturing
(The Eurographics Association, 2001)
MIP mapping is a common method used by graphics hardware to avoid texture aliasing. In many situations, MIP mapping over-blurs in one direction to prevent aliasing in another. Anisotropic texturing reduces this blurring ...
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 ...
Statistical Simulation of Rigid Bodies
(ACM SIGGRAPH / Eurographics Association, 2009)
We describe a method for replacing certain stages of rigid body simulation with a statistically-based approximation. We begin by collecting statistical data regarding changes in linear and angular momentum for collisions ...
Automatic Shader Level of Detail
(The Eurographics Association, 2003)
Current graphics hardware can render procedurally shaded objects in real-time. However, due to resource and performance limitations, interactive shaders can not yet approach the complexity of shaders written for film ...
Perlin Noise Pixel Shaders
(The Eurographics Association, 2001)
While working on a method for supporting real-time procedural solid texturing, we developed a general purpose multipass pixel shader to generate the Perlin noise function. We implemented this algorithm on SGI workstations ...
Tile-Based Texture Mapping on Graphics Hardware
(The Eurographics Association, 2004)
Texture mapping has been a fundamental feature for commodity graphics hardware. However, a key challenge for texture mapping is how to store and manage large textures on graphics processors. In this paper, we present a ...
An Effective Hardware Architecture for Bump Mapping Using Angular Operation
(The Eurographics Association, 2003)
In this paper, we propose an effective bump mapping algorithm that utilizes the reference space with the polar coordinate system and also propose a new hardware architecture associated with the proposed bump mapping ...
The Ray Engine
(The Eurographics Association, 2002)
Assisted by recent advances in programmable graphics hardware, fast rasterization-based techniques have made significant progress in photorealistic rendering, but still only render a subset of the effects possible with ray ...
Quasi-Linear Depth Buffers With Variable Resolution
(The Eurographics Association, 2001)
In this paper we present new class of variable-resolution depth buffers, providing a flexible trade-off between depth precision in the distant areas of the view volume and performance. These depth buffers can be implemented ...
