Visualization For Public-Resource Climate Modeling
(The Eurographics Association, 2004)Climateprediction.net aims to harness the spare CPU cycles of a million individual users PCs to run a massive ensemble of climate simulations using an up-to-date, full-scale 3D atmosphere-ocean climate model. Although it ... -
DTI Visualization with Streamsurfaces and Evenly-Spaced Volume Seeding
(The Eurographics Association, 2004)Experimental evidence has shown that water diffusion is anisotropic in organized tissues such as white matter or muscles. Diffusion Tensor Imaging is a non-invasive MR technique that measures water diffusion. DTI is used ... -
A Cluster-Space Visual Interface for Arbitrary Dimensional Classification of Volume Data
(The Eurographics Association, 2004)In volume visualization, users typically specify transfer functions to classify the data and assign visual attributes to each material class. Higher-dimensional classification makes it easier to differentiate material ... -
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 ... -
Volume Visualization and Visual Queries for Large High-Dimensional Datasets
(The Eurographics Association, 2004)We propose a flexible approach for the visualization of large, high-dimensional datasets. The raw, highdimensional data is mapped into an abstract 3D distance space using the FastMap algorithm, which helps, together with ... -
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 ... -
Efficient Isosurface Tracking Using Precomputed Correspondence Table
(The Eurographics Association, 2004)Feature tracking is a useful method for visualizing and analyzing time-varying scalar fields. It allows scientists to focus on regions of interest and track their evolution and interaction over time. To allow the user to ... -
Visualization of Anatomic Tree Structures with Convolution Surfaces
(The Eurographics Association, 2004)We present a method for visualizing anatomic tree structures, such as vasculature and bronchial trees based on clinical CT- or MR data. The vessel skeleton as well as the diameter information per voxel serve as input. Our ... -
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, ... -
A Botanically Inspired High-Dimensional Visualization with Multivariate Glyphs
(The Eurographics Association, 2004)It is difficult for the average viewer to assimilate and comprehend huge amounts of high-dimensional data. It is important to present data in a way that allows the user a high level understanding of the overall organization ... -
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 ... -
Efficient Display of Background Objects for Virtual Endoscopy using Flexible First-Hit Ray Casting
(The Eurographics Association, 2004)Many applications of virtual endoscopy require the display of background objects behind the semi-transparent surface of the investigated organ. This paper deals with pre-processing and visualization of background objects ... -
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 ... -
Generalized Distance Transforms and Skeletons in Graphics Hardware
(The Eurographics Association, 2004)We present a framework for computing generalized distance transforms and skeletons of two-dimensional objects using graphics hardware. Our method is based on the concept of footprint splatting. Combining different splats ... -

Auralization I: Vortex Sound Synthesis
(The Eurographics Association, 2004)Auralization is the process of extracting and displaying meaningful information in the form of sound from data. Through not only visualization but also auralization, users may have better understandings of the data, ... -
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 ... -
Visualization of Cardio-CT Data on Standard PC Hardware
(The Eurographics Association, 2004)In the last years, texture based volume rendering on the PC platform has proven very successful. Many methods that could formerly only be done with software renderers can now be done completely by the graphics hardware. ... -
Occlusion Culling for Sub-Surface Models in Geo-Scientific Applications
