Accelerating Raycasting Utilizing Volume Segmentation of Industrial CT Data
(The Eurographics Association, 2009)
We propose a flexible acceleration technique for raycasting targeted at industrial CT data and the context of material deficiency checking. Utilizing volume segmentation that is typically employed for object analysis, GPU ...
GPU-based Visualisation of Protein Secondary Structure
(The Eurographics Association, 2008)
The increasing number of protein 3D structure information available makes the high-quality visualisation of this information play a more and more important role. Beside element-based representations the secondary-structurebased ...
Implementing FastMap on the GPU: Considerations on General-Purpose Computation on Graphics Hardware
(The Eurographics Association, 2005)
In this paper we focus on the implications of implementing generic algorithms on graphics hardware. As an example, we ported the dimensionality reduction algorithm FastMap to fragment programs and thus accelerated it by ...
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, ...
Interactive Visualization with Programmable Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2002)
One of the main scientific goals of visualization is the development of algorithms and appropriate data models which facilitate interactive visual analysis and direct manipulation of the increasingly large data sets which ...
Enhancing the Interactive Visualization of Procedurally Encoded Multifield Data with Ellipsoidal Basis Functions
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
Functional approximation of scattered data is a popular technique for compactly representing various types of datasets in computer graphics, including surface, volume, and vector datasets. Typically, sums of Gaussians or ...
OpenManip: An Extensible Cross-Scene-Graph Framework for Direct Object Manipulation
(The Eurographics Association, 2003)
In this paper we describe a framework that exploits 3D widgets in order to allow for the direct manipulation of scene graph objects. The design of the frameworks is inspired by the OpenInventor manipulator functionality, ...
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)

An E-Learning Course on Scientific Visualization
(The Eurographics Association, 2007)
In this paper we present an e-learning course on scientific visualization. Based on over ten years of teaching experiences in this field, we have created a multimedia online course which we use as additional material for ...
