GPU-Based Hyperstreamlines for Diffusion Tensor Imaging
(The Eurographics Association, 2006)We propose a new approach for the visualization of hyperstreamlines, which offers potential for better scalability than the conventional polygon-based approach. Our method circumvents the bandwidth bottleneck between the ... -
GPUFLIC: Interactive and Accurate Dense Visualization of Unsteady Flows
(The Eurographics Association, 2006)The paper presents an efficient and accurate implementation of Unsteady Flow LIC (UFLIC) on the Graphics Processing Unit (GPU). We obtain the same, high quality texture representation of unsteady two-dimensional flows as ... -
Hardware-accelerated Extraction and Rendering of Point Set Surfaces
(The Eurographics Association, 2006)Point-based models are gaining lately considerable attention as an alternative to traditional surface meshes. In this context, Point Set Surfaces (PSS) were proposed as a modeling and rendering method with important ... -
GPU-Accelerated Volume Splatting With Elliptical RBFs
(The Eurographics Association, 2006)Radial Basis Functions (RBFs) have become a popular rendering primitive, both in surface and in volume rendering. This paper focuses on volume visualization, giving rise to 3D kernels. RBFs are especially convenient for ... -
Combining Silhouettes, Surface, and Volume Rendering for Surgery Education and Planning
(The Eurographics Association, 2005)We introduce a flexible combination of volume, surface, and line rendering.We employ object-based edge detection because this allows a flexible parametrization of the generated lines. Our techniques were developed mainly ... -
Interactive Visualization for Neck-Dissection Planning
(The Eurographics Association, 2005)In this paper, we present visualization techniques for neck dissection planning. These interventions are carried out to remove lymph node metastasis in the neck region. 3d visualization is intended to explore and to quantify ... -
BioBrowser: A Framework for Fast Protein Visualization
(The Eurographics Association, 2005)This paper presents a protein visualization system called BioBrowser, which provides high quality images at interactive frame rates for molecules of extreme size and complexity. This is achieved by a shift in the tessellation ... -
Spatialized Transfer Functions
(The Eurographics Association, 2005)Multi-dimensional transfer functions are an efficient way to visualize features in scalar volume data produced by CT or MRI scanners. However, the optimal transfer function is difficult to find in general. We present an ... -
Interactive Methods for Exploring Particle Simulation Data
(The Eurographics Association, 2005)In this work, we visualize high-dimensional particle simulation data using a suite of scatterplot-based visualizations coupled with interactive selection tools. We use traditional 2D and 3D projection scatterplots as well ... -
Extending and Simplifying Transfer Function Design in Medical Volume Rendering Using Local Histograms
(The Eurographics Association, 2005)Direct Volume Rendering (DVR) is known to be of diagnostic value in the analysis of medical data sets. However, its deployment in everyday clinical use has so far been limited. Two major challenges are that the current ... -
Discovering High-level Parameters for Visualization Design
(The Eurographics Association, 2005)In most graphics and visualization applications, the effects of the mapping parameters on the output domain are multidimensional, non-linear and discontinuous. The complexity of such mapping often makes it difficult for a ... -
Mail Explorer - Spatial and Temporal Exploration of Electronic Mail
(The Eurographics Association, 2005)In today s world, e-mail has become one of the most important means of communication in business and private lives due to its efficiency. However, the problems start as soon as mail volumes go beyond the scope of human ... -
MoireTrees: Visualization and Interaction for Multi-Hierarchical Data
(The Eurographics Association, 2005)Visualizing hierarchical data is one of the core areas of information visualization. Most of these techniques focus on single hierarchies hierarchies with a single root element and a single path to each element. In contrast, ... -
Spline-Based Gradient Filters For High-Quality Refraction Computations in Discrete Datasets
(The Eurographics Association, 2005)Based on the finding that refraction imposes significantly higher demands onto gradient filters than illumination and shading, we evaluate the family of spline filters as a good alternative to the cubic filters, which so ... -
Version-Centric Visualization of Code Evolution
(The Eurographics Association, 2005)The source code of software systems changes many times during the system lifecycle. We study how developers can get insight in these changes in order to understand the project context and the product artifacts. For this ... -
Visualisation and Analysis of Large and Complex Scale-free Networks
(The Eurographics Association, 2005)Scale-free networks appear in many application domains such as social and biological networks [BA99, BB03, BO04]. Roughly speaking, scale-free networks have power-law degree distribution, ultra-short average path length ... -
Visualization of Computer-Modeled Forests for Forest Management
(The Eurographics Association, 2005)Forest management is a costly and time-consuming activity. Remote sensing has the potential to improve the process by making it cheaper and more efficient, but only if appropriate characteristics can be determined from ... -
Non-manifold Mesh Extraction from Time-varying Segmented Volumes used for Modeling a Human Heart
(The Eurographics Association, 2005)We present a new algorithm extracting and fairing surfaces from segmented volumes composed of multiple materials. In a first pass, the material boundaries in the volume are smoothed considering signed distance functions ... -
Isosurface Extraction Using Fixed-Sized Buckets
(The Eurographics Association, 2005)We present a simple and output optimal algorithm for accelerated isosurface extraction from volumetric data sets. Output optimal extraction algorithms perform an amount of work dominated by the size of the (output) isosurface ... -
