Illustrating Surfaces in Volume
(The Eurographics Association, 2004)This paper presents a novel framework for illustrating surfaces in a volume. Surfaces are illustrated by drawing only feature lines, such as silhouettes, valleys, ridges, and surface hatching strokes, and are embedded in ... -
Interaction Spaces in Data and Information Visualization
(The Eurographics Association, 2004)User interaction plays an integral part in the effective visualization of data and information. Typical interaction operations include navigation, selection, and distortion. A problem that can occur when these operations ... -
Interactive High Quality Trimmed NURBS Visualization Using Appearance Preserving Tessellation
(The Eurographics Association, 2004)Trimmed NURBS models are the standard representation used in CAD/CAM systems and accurate visualization of large trimmed NURBS models at interactive frame rates is of great interest for industry. To visualize the quality ... -
Interactive TreemapsWith Detail on Demand to Support Information Search in Documents
(The Eurographics Association, 2004)This paper addresses the issue of how information visualization techniques can be used to assist full-text search in electronic documents. Our approach supports multiple term queries with interactive treemaps. We use a ... -
Interactively Visualizing Procedurally Encoded Scalar Fields
(The Eurographics Association, 2004)While interactive visualization of rectilinear gridded volume data sets can now be accomplished using texture mapping hardware on commodity PCs, interactive rendering and exploration of large scattered or unstructured data ... -
Medical Applications of Multi-Field Volume Rendering and VR Techniques
(The Eurographics Association, 2004)This paper reports on a new approach for visualizing multi-field MRI or CT datasets in an immersive environment with medical applications. Multi-field datasets combine multiple scanning modalities into a single 3D, ... -
Meshless Isosurface Generation from Multiblock Data
(The Eurographics Association, 2004)We propose a meshless method for the extraction of high-quality continuous isosurfaces from volumetric data represented by multiple grids, also called "multiblock" data sets. Multiblock data sets are commonplace in ... -
Occlusion Culling for Sub-Surface Models in Geo-Scientific Applications
(The Eurographics Association, 2004)Modern graphics cards support occlusion culling in hardware. We present a three pass algorithm, which makes efficient use of this feature. Our geo-scientific sub-surface data sets consist typically of a set of high resolution ... -
Ray Casting Curved-Quadratic Elements
(The Eurographics Association, 2004)We present a method for ray casting curved-quadratic elements in 3D. The advantages of this approach is that a curved element can be directly visualized. Conventionally, higher-order elements are tessellated with several ... -
Shape-Embedded-Histograms for Visual Data Mining
(The Eurographics Association, 2004)Scatterplots are widely used in exploratory data analysis and class visualization. The advantages of scatterplots are that they are easy to understand and allow the user to draw conclusions about the attributes which span ... -
Software Landscapes: Visualizing the Structure of Large Software Systems
(The Eurographics Association, 2004)Modern object-oriented programs are hierarchical systems with many thousands of interrelated subsystems. Visualization helps developers to better comprehend these large and complex systems. This paper presents a three-dimensional ... -
Superquadric Tensor Glyphs
(The Eurographics Association, 2004)Tensor field visualization is a challenging task due in part to the multi-variate nature of individual tensor samples. Glyphs convey tensor variables by mapping the tensor eigenvectors and eigenvalues to the orientation ... -
Surface Techniques for Vortex Visualization
(The Eurographics Association, 2004)This paper presents powerful surface based techniques for the analysis of complex flow fields resulting from CFD simulations. Emphasis is put on the examination of vortical structures. An improved method for stream surface ... -
Techniques for Visualizing Multi-Valued Flow Data
(The Eurographics Association, 2004)In this paper we discuss several techniques to display multiple scalar distributions within an image depicting a 2D flow field. We first address how internal contrast and mean luminance can effectively be used to represent ... -
Texture-Based Flow Visualization on Isosurfaces from Computational Fluid Dynamics
(The Eurographics Association, 2004)Isosurfacing, by itself, is a common visualization technique for investigating 3D vector fields. Applying texturebased flow visualization techniques to isosurfaces provides engineers with even more insight into the ... -
TimeHistograms for Large, Time-Dependent Data
(The Eurographics Association, 2004)Histograms are a very useful tool for data analysis, because they show the distribution of values over a data dimension. Many data sets in engineering (like computational fluid dynamics, CFD), however, are time-dependent. ... -
Visual Component Analysis
(The Eurographics Association, 2004)We propose to integrate information visualization techniques with factor analysis. Specifically, a principal direction derived from a principal component analysis (PCA) of the data is displayed together with the data in a ... -
Visual Triangulation of Network-Based Phylogenetic Trees
(The Eurographics Association, 2004)Phylogenetic trees are built by examining differences in the biological traits of a set of species. An example of such a trait is a biological network such as a metabolic pathway, common to all species but with subtle ... -
Visualising Organisms with Hydraulic Body Parts: A Case Study in Integrating Simulation and Visualisation Models
(The Eurographics Association, 2004)The physical structure of organisms can be modelled as a set of coupled hydraulic entities. The hydropneumatic biosimulation is a methodology that is able to simulate the behavior (like movements) of such organisms on the ... -
