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 ... -
A Simple and Novel Seed-Set Finding Approach for Iso-Surface Extraction
(The Eurographics Association, 2005)Iso-surface extraction is one of the most important approaches for volume rendering, and iso-contouring is one of the most effective methods for iso-surface extraction. Unlike most other methods having their search domain ... -
Interactive rendering of massive terrains on PC clusters
(The Eurographics Association, 2005)We describe a parallel framework for interactive smooth rendering of massive terrains. We define a parallelization scheme for level of detail algorithms in cluster-based environments. The scheme relies on modern PC clusters ... -
VIS-a-VE: Visual Augmentation for Virtual Environments in Surgical Training
(The Eurographics Association, 2005)Photo-realistic rendering combined with vision techniques is an important trend in developing next generation surgical simulation devices. Training with simulator is generally low in cost and more efficient than traditional ... -
VisBiz: A Business Process Visualization Case Study
(The Eurographics Association, 2005)Business process management involves many parameters and relationships and is modeled as complex business process workflows. A common way to analyze the process data is by using flowcharts. Visual analysis of a largescale ... -
Transfer Functions for Imaging Spectroscopy Data using Principal Component Analysis
(The Eurographics Association, 2005)In this paper we present a new application of the principal component analysis (PCA) to generate multidimensional transfer functions. These transfer functions are needed in the volumetric visualization of spectral data to ... -
High-Quality Volume Rendering with Resampling in the Frequency Domain
(The Eurographics Association, 2005)This work introduces a volume rendering technique that is conceptually based on the shear-warp factorization. We propose to perform the shear transformation in the frequency domain. Unlike the standard shear-warp algorithm, ... -
Visualization for Validation and Improvement of Three-dimensional Segmentation Algorithms
(The Eurographics Association, 2005)The Berkeley DrosophilaTranscription Network Project (BDTNP) is developing a suite of methods that will allow a quantitative description and analysis of three dimensional (3D) gene expression patterns in an animal with ... -
High-Quality Rendering of Compressed Volume Data Formats
(The Eurographics Association, 2005)Rendering directly from packed or compressed volume data formats using graphics hardware has advantages in terms of memory consumption and bandwidth, but results in lower-quality images due to the prohibitive cost of ... -
Illustrative Context-Preserving Volume Rendering
(The Eurographics Association, 2005)In volume rendering it is very difficult to simultaneously visualize interior and exterior structures while preserving clear shape cues. Very transparent transfer functions produce cluttered images with many overlapping ... -
ArcTrees: Visualizing Relations in Hierarchical Data
(The Eurographics Association, 2005)In this paper we present, ARCTREES, a novel way of visualizing hierarchical and non-hierarchical relations within one interactive visualization. Such a visualization is challenging because it must display hierarchical ... -
Tiled Parallel Coordinates for the Visualization of Time-Varying Multichannel EEG Data
(The Eurographics Association, 2005)The field of visualization assists data interpretation in many areas, but some types of data are not manageable by existing visualization techniques. This holds in particular for time-varying multichannel EEG data. No ... -
The i-Disc - A Tool To Visualize and Explore Topic Maps
(The Eurographics Association, 2005)We present the i-Disc, a tool to interactively visualize and explore medium sized topic maps. Topic maps contain two basic structures: the topic hierarchy and the associations between topics. Our system presents the topic ... -
Scalable, Robust Visualization of Very Large Trees
(The Eurographics Association, 2005)The TreeJuxtaposer system [MGT*03] allowed visual comparison of large trees with guaranteed visibility of landmarks and Focus+Context navigation. While that system allowed exploration and comparison of larger datasets than ... -
Vector Field Analysis and Visualization through Variational Clustering
(The Eurographics Association, 2005)Scientific computing is an increasingly crucial component of research in various disciplines. Despite its potential, exploration of the results is an often laborious task, owing to excessively large and verbose datasets ... -
Dense Geometric Flow Visualization
(The Eurographics Association, 2005)We present a flow visualization technique based on rendering geometry in a dense, uniform distribution. Flow is integrated using particle advection. By adopting ideas from texture-based techniques and taking advantage of ... -
Real-Time Advection and Volumetric Illumination for the Visualization of 3D Unsteady Flow
(The Eurographics Association, 2005)This paper presents an interactive technique for the dense texture-based visualization of unsteady 3D flow, taking into account issues of computational efficiency and visual perception. High efficiency is achieved by a ... -
Dynamically Modelling Interaction
(The Eurographics Association, 2005)Technological advances are increasing the use of dynamic or changing displays, in many forms of interface. The increasing amount of information held on the Internet and in private government and commercial databases also ...
