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 ...
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 ...
Contextual Visualization of Actor Status in Social Networks
(The Eurographics Association, 2000)
We propose a novel information visualization approach for an analytical method applied in the social sciences. In social network analysis, social structures are formally represented as graphs, and structural properties of ...
Hierarchical Data Representations Based on Planar Voronoi Diagrams
(The Eurographics Association, 2000)
Multiresolution representation of high-dimensional scattered data is a fundamental problem in scientific visualization. This paper introduces a data hierarchy of Voronoi diagrams as a versatile solution. Given an arbitrary ...
Galilean Invariant Extraction and Iconic Representation of Vortex Core Lines
(The Eurographics Association, 2005)
While vortex region quantities are Galilean invariant, most methods for extracting vortex cores depend on the frame of reference. We present an approach to extracting vortex core lines independently of the frame of reference ...
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 ...
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 ...
Localized Flow Analysis of 2D and 3D Vector Fields
(The Eurographics Association, 2005)
In this paper we present an approach to the analysis of the contribution of a small subregion in a dataset to the global flow. To this purpose, we subtract the potential flow that is induced by the boundary of the sub-domain ...
Topology-Based Visualization of Time-Dependent 2D Vector Fields
(The Eurographics Association, 2001)
Topology-based methods have been successfully applied to the visualization of instantaneous planar vector fields. In this paper, we present the topology-based visualization of time-dependent 2D flows. Our method tracks ...
Accelerated Force Computation for Physics-Based Information Visualization
(The Eurographics Association, 2003)
Visualization of similarity is an emerging technique for analyzing relation-based data sets. A common way of computing the respective layouts in an information space is to employ a physics-based mass-spring system. Force ...
