Enhanced Sphere Tracing
(The Eurographics Association, 2014)
In this paper we present several performance and quality enhancements to classical sphere tracing: First, we propose a safe, over-relaxation-based method for accelerating sphere tracing. Second, a method for dynamically ...
Stateless Level of Detail Lighting for Automotive Visualization
(The Eurographics Association, 2014)
Car models typically consist of highly specular surfaces including sharp angles. Renderings of such models contain very fine, sharp lighting features, that both make Level-of-Detail switches well visible and result in ...
Efficient Glossy Global Illumination with Interactive Viewing
(Blackwell Publishers Ltd and the Eurographics Association, 2000)
The ability to perform interactive walkthroughs of global illumination solutions including glossy effects is a challenging open problem. In this paper we overcome certain limitations of previous approaches. We first introduce ...
Grid Based Final Gather for Radiosity on Complex Clustered Scenes
(Blackwell Publishers, Inc and the Eurographics Association, 2002)
Radiosity methods handle large scenes and complex objects using clustering techniques. To reconstruct a high quality image, usually a second very time consuming final gather pass is applied which exactly recomputes the ...
Data‐Parallel Decompression of Triangle Mesh Topology
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We propose a lossless, single‐rate triangle mesh topology codec tailored for fast data‐parallel GPU decompression. Our compression scheme coherently orders generalized triangle strips in memory. To unpack generalized ...
Using Subdivision on Hierarchical Data to Reconstruct Radiosity Distribution
(Blackwell Publishers Ltd and the Eurographics Association, 1997)
Computing global illumination by finite element techniques usually generates a piecewise constant approximation of the radiosity distribution on surfaces. Directly displaying such scenes generates artefacts due to ...
Bitmask Soft Shadows
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
Recently, several real-time soft shadow algorithms have been introduced which all compute a single shadow map and use its texels to obtain a discrete scene representation. The resulting micropatches are backprojected onto ...
Bounded Radiosity - Illumination on General Surfaces and Clusters
(Blackwell Publishers Ltd and the Eurographics Association, 1997)
Traditionally, Radiosity algorithms have been restricted to scenes made from planar patches. Most algorithms for computing form factors and the subdivision criterion for hierarchical methods implicitly assume planar patches. ...
Faster Ray-Traced Shadows for Hybrid Rendering of Fully Dynamic Scenes by Pre-BVH Culling
(The Eurographics Association, 2015)
With ever increasing ray traversal and hierarchy construction performance the application of ray tracing to problems often tackled by rasterization-based algorithms is becoming a viable alternative. This is especially ...
An Efficient Solution to Structured Optimization Problems using Recursive Matrices
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a linear algebra framework for structured matrices and general optimization problems. The matrices and matrix operations are defined recursively to efficiently capture complex structures and enable advanced ...
