Feature-Preserving Volume Filtering
(The Eurographics Association, 2002)
In this paper a feature-preserving volume filtering method is presented. The basic idea is to minimize a threecomponent global error function penalizing the density and gradient errors and the curvature of the unknown ...
Adding a scalar value to texture-based vector field representations by local contrast analysis
(The Eurographics Association, 2002)
Several algorithms can effectively represent vector fields by texture-based representations, visualizing at most all information on the field: direction, orientation, and local magnitude. An open problem still remains the ...
Secondary Task Display Attributes - Optimizing Visualizations for Cognitive Task Suitability and Interference Avoidance
(The Eurographics Association, 2002)
We found that established display design guidelines for focal images cannot be extended to images displayed as a secondary task in a dual-task situation. This paper describes an experiment that determines a new ordering ...
Comparison of Morphological Pyramids for Multiresolution MIP Volume Rendering
(The Eurographics Association, 2002)
We recently proposed a multiresolution representation for maximum intensity projection (MIP) volume rendering based on morphological adjunction pyramids which allow progressive refinement and have the property of perfect ...
Visualization of Bibliographic Networks with a Reshaped Landscape Metaphor
(The Eurographics Association, 2002)
We describe a novel approach to visualize bibliographic networks that facilitates the simultaneous identification of clusters (e.g., topic areas) and prominent entities (e.g., surveys or landmark papers). While employing ...
Shear-Warp Deluxe: The Shear-Warp Algorithm Revisited
(The Eurographics Association, 2002)
Despite continued advances in volume rendering technology, the Shear-Warp algorithm, although conceived as early as 1994, still remains the world s fastest purely software-based volume rendering algorithm. The impressive ...
AUFLIC: An Accelerated Algorithm For Unsteady Flow Line Integral Convolution
(The Eurographics Association, 2002)
UFLIC (Unsteady Flow Line Integral Convolution) is an effective texture synthesis technique to visualize unsteady flow with enhanced temporal coherence, but it is time-consuming to generate. This paper presents an accelerated ...
A Continuous Skeletonization Method Based on Level Sets
(The Eurographics Association, 2002)
A robust and efficient method in 2D and 3D for the calculation of skeletons for arbitrary objects is presented. The method is based on the calculation of the distance function with respect to the object boundary. This is ...
A Novel Approach To Vortex Core Region Detection
(The Eurographics Association, 2002)
In this paper we present a simple and efficient vortex core region detection algorithm based on ideas derived from combinatorial topology. These ideas originated from Sperner s lemma, which by itself is of little value to ...
Octreemizer: A Hierarchical Approach for Interactive Roaming Through Very Large Volumes
(The Eurographics Association, 2002)
We have developed a hierarchical paging scheme for handling very large volumetric data sets at interactive frame rates. Our system trades texture resolution for speed and uses effective prediction strategies. We have tested ...
