GPU-Based Nonlinear Ray Tracing
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
In this paper, we present a mapping of nonlinear ray tracing to the GPU which avoids any data transfer back to main memory. The rendering process consists of the following parts: ray setup according to the camera parameters, ...
Voronoi-Based Foveated Volume Rendering
(The Eurographics Association, 2019)
Foveal vision is located in the center of the field of view with a rich impression of detail and color, whereas peripheral vision occurs on the side with more fuzzy and colorless perception. This visual acuity fall-off can ...
Evaluation of Visualizations for Interface Analysis of SPH
(The Eurographics Association, 2014)
We present a GPU-accelerated visualization application that employs methods from computer graphics and visualizationto analyze SPH simulations from the field of material science. To this end, we extract the isosurfacethat ...
GPU-assisted Multi-field Video Volume Visualization
(The Eurographics Association, 2006)
GPU-assisted multi-field rendering provides a means of generating effective video volume visualization that can convey both the objects in a spatiotemporal domain as well as the motion status of these objects. In this ...
Programmable Graphics Hardware for Interactive Visualization
(Eurographics Association, 2002)
Shadow Mapping Based on Dual Depth Layers
(Eurographics Association, 2003)
Shadow maps are a widely used means for the generation of shadows although they exhibit aliasing artifacts and problems of numerical precision. In this paper we extend the concept of a single shadow map by introducing dual ...
Real-Time Advection and Volumetric Illumination for the Visualization of 3D Unsteady Flow
(The Eurographics Association, 2005)
This paper presents an interactive technique for the dense texture-based visualization of unsteady 3D flow, taking into account issues of computational efficiency and visual perception. High efficiency is achieved by a ...
Smart Hardware-Accelerated Volume Rendering
(The Eurographics Association, 2003)
For volume rendering of regular grids the display of view-plane aligned slices has proven to yield both good quality and performance. In this paper we demonstrate how to merge the most important extensions of the original ...
Visualization of Advection-Diffusion in Unsteady Fluid Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Advection has been the standard transport mechanism in flow visualization. Diffusion, in contrast, has not been considered important in visual flow field analysis so far, although it is inherent to many physical processes. ...
Topology-Preserving lambda_2-based Vortex Core Line Detection for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2008)
We propose a novel vortex core line extraction method based on the lambda_2 vortex region criterion in order to improve the detection of vortex features for 3D flow visualization. The core line is defined as a curve that ...
