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 ... -
Visualization of Thermal Flows in an Automotive Cabin with Volume Rendering Method
(The Eurographics Association, 2001)A predictive system of thermal flow with quick turnaround time in a passenger compartment has been developed. An efficient method based on the Cartesian mesh system was used to reduce the period of analysis. The computed ... -
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 ... -
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 ... -
Volume Rendering Data with Uncertainty Information
(The Eurographics Association, 2001)This paper explores two general methods for incorporating volumetric uncertainty information in direct volume rendering. The goal is to produce volume rendered images that depict regions of high (or low) uncertainty in the ... -
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 ... -
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. ... -
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 ... -
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, ... -
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 ... -
A Selective Refinement Approach for Computing the Distance Functions of Curves
(The Eurographics Association, 2001)We present an adaptive signed distance transform algorithm for curves in the plane. A hierarchy of bounding boxes is required for the input curves. We demonstrate the algorithm on the isocontours of a turbulence simulation. ... -
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 ... -
Visualization of directed associations in e-commerce transaction data
(The Eurographics Association, 2001)Many real-world e-commerce applications require the mining of large volumes of transaction data to extract marketing and sales information. This paper describes the Directed Association Visualization (DAV) system that ... -
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 ... -
Visualization of Generalized Voronoi Diagrams
(The Eurographics Association, 2001)Voronoi diagrams are an important data structure in computer science. However well studied mathematically, understanding such diagrams for different metrics, orders, and site shapes is a complex task. We propose a new ... -
Space-Efficient Boundary Representation of Volumetric Objects
(The Eurographics Association, 2001)In this paper we present a compression technique for efficiently representing boundary objects from volumetric data-sets. Exploiting spatial coherency within object contours, we are able to reduce the size of the volumetric ... -
Three-dimensional Reconstruction and Visualization of the Cerebral Cortex in Primates
(The Eurographics Association, 2001)We present a prototype interactive application for the direct analysis in three dimensions of the cerebral cortex in primates. The paper provides an overview of the current prototype system and presents the techniques used ... -
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 ... -
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 ...
