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, ...
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 ...
Employing Complex GPU Data Structures for the Interactive Visualization of Adaptive Mesh Refinement Data
(The Eurographics Association, 2006)
We present a framework for interactively visualizing volumetric Adaptive Mesh Refinement (AMR) data. For this purpose we employ complex data structures to map the entire AMR dataset to graphics memory. This allows to apply ...
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 ...
