Acquisition and Display of Real-Time Atmospheric Data on Terrain
(The Eurographics Association, 2001)This paper investigates the integrated acquisition, organization, and display of data from disparate sources, including the display of data acquired in real-time. In this case real-time acquisition and display refers to ... -
Adaptive Volume Rendering using Fuzzy Logic Control
(The Eurographics Association, 2001)This paper presents an automatic error tolerance specification system to control the performance of hierarchical volume rendering. Rather than requiring the user to provide an explicit error tolerance numerically, we let ... -
Automotive Soiling Simulation Based On Massive Particle Tracing
(The Eurographics Association, 2001)In the automotive industry Lattice-Boltzmann type flow solvers like PowerFlow from Exa Corporation are becoming increasingly important. In contrast to the traditional finite volume approach PowerFlow utilizes a hierachical ... -
A Case Study in Multi-Sensory Investigation of Geoscientific Data
(The Eurographics Association, 2001)In this paper, we report our ongoing research into multi-sensory investigation of geoscientific data. Our Geoscientific Data Investigation System (GDIS) integrates three-dimensional, interactive computer graphics, touch ... -
Case Study: Visualization and Information Retrieval Techniques for Network Intrusion Detection
(The Eurographics Association, 2001)We describe our efforts to analyze network intrusion detection data using information retrieval and visualization tools. By regarding Telnet sessions as documents, which may or may not include attacks, a session that ... -
Comparative Visualization of Instabilities in Crash-Worthiness Simulations
(The Eurographics Association, 2001)Since crash-worthiness simulations get more and more important as part of the car development process in order to reduce the cost of development, enhance the product quality, and minimize the time-to-market, the reliability ... -
DDDiver: 3D Interactive Visualization of Entity Relationships
(The Eurographics Association, 2001)In this paper we present DDDiver, a tool for the interactive visualization and editing of Object-Oriented databases. It was developed to visualize and manipulate large loosely-structured data sets with multiple relation ... -
Extraction of Crack-free Isosurfaces from Adaptive Mesh Refinement Data
(The Eurographics Association, 2001)Adaptive mesh refinement (AMR) is a numerical simulation technique used in computational fluid dynamics (CFD). It permits the efficient simulation of phenomena characterized by substantially varying scales in complexity ... -
Fast Multiresolution Extraction of Multiple Transparent Isosurfaces
(The Eurographics Association, 2001)In this paper, we present a multiresolution algorithm which is capable to render multiple transparent isosurfaces under real time constraints. To this end, the underlying 3D data set is covered with a hierarchical tetrahedral ... -
A Hardware-Assisted Visibility-Ordering Algorithm With Applications To Volume Rendering
(The Eurographics Association, 2001)We propose a hardware-assisted visibility ordering algorithm. From a given viewpoint, a (back-to-front) visibility ordering of a set of objects is a partial order on the objects such that if object A obstructs object B, ... -
I/O-Conscious Volume Rendering
(The Eurographics Association, 2001)Most existing volume rendering algorithms assume that data sets are memory-resident and thus ignore the performance overhead of disk I/O. While this assumption may be true for high-performance graphics machines, it does ... -
Improved visualization in virtual colonoscopy using image-based rendering
(The Eurographics Association, 2001)Virtual colonoscopy (VC) is a patient-friendly alternative for colorectal endoscopic examination. We explore visualization aspects of VC such as surface in view, navigation and communication of a diagnosis. A series of ... -
Interacting with Stock Market Data in a Virtual Environment
(The Eurographics Association, 2001)Virtual Environment technology enables new styles of user interfaces that provide multi-sensory interactions. For example, interfaces can be designed which immerse the user in a 3D space and provide multi-sensory feedback. ... -
Interactive and Multi-modal Visualization for Neuroendoscopic Interventions
(The Eurographics Association, 2001)Based on the VIVENDI-framework for virtual endoscopy, we present a system for the interactive and multi-modal representation of important anatomical structures for neuroendoscopic interventions. A serious problem of ... -
Multiresolution Maximum Intensity Volume Rendering by Morphological Pyramids
(The Eurographics Association, 2001)We propose a multiresolution representation for maximum intensity projection (MIP) volume rendering, based on morphological pyramids which allow progressive refinement and have the property of perfect reconstruction. The ... -
Nonlinear Diffusion in Graphics Hardware
(The Eurographics Association, 2001)Multiscale methods have proved to be successful tools in image denoising, edge enhancement and shape recovery. They are based on the numerical solution of a nonlinear diffusion problem where a noisy or damaged image which ... -
Preserving the Mental Map using Foresighted Layout
(The Eurographics Association, 2001)First we introduce the concept of graph animations as a sequence of evolving graphs and a generic algorithm which computes a Foresighted Layout for dynamically drawing these graphs while preserving the mental map. The ... -
Progressive View-Dependent Isosurface Propagation
(The Eurographics Association, 2001)This paper proposes a new isosurface extraction algorithm that extracts portions of the isosurface in a view-dependent manner by ray casting and propagation. The algorithm casts rays through a volume to find visible active ... -
The Rendering of Unstructured Grids Revisited
(The Eurographics Association, 2001)In this paper we propose a technique for resampling scalar fields given on unstructured tetrahedral grids. This technique takes advantage of hardware accelerated polygon rendering and 2D texture mapping and thus avoids any ... -
Salient Representation of Volume Data
(The Eurographics Association, 2001)We introduce a novel method for identification of objects of interest in volume data. Our approach conveys the information contained in two essentially different concepts, the object s boundaries and the narrow solid ...
