VISSION: An Object Oriented Dataflow System for Simulation and Visualization
(Springer and The Eurographics Association, 1999)Scientific visualization and simulation speciification and monitoring are sometimes addressed by object-oriented environments. Even though object orientation powerfully and elegantly models many application domains, ... -
Visualization of Molecules with Positional Uncertainty
(Springer and The Eurographics Association, 1999)Designing new and better chemotherapeutic wmpounds requires an understanding of the mechanism by which the drugs exert their biological effects. This involves consideration of the geometry of the active site, determination ... -
Visualization by Examples: Mapping Data to Visual Representations using Few Correspondences
(Springer and The Eurographics Association, 1999)In this paper we propose a new approach for the generation of visual scales for the visualization of scalar and multivariate data. Based on the specification of only a few correspondences between the data set and elements ... -
Visualization of Grinding Processes
(Springer and The Eurographics Association, 1999)In grinding technology, the application ofsupcrabrasivcs and increasing demands for higher productivity and higher quality require an appropriate selection of optimum set-up parameters. An efficient way to determine and ... -
VIVENDI - A Virtual Endoscopy System for Virtual Medicine
(Springer and The Eurographics Association, 1999)Virtual Medicine is an emerging and challenging field in Computer Graphics. Numerous visualization methods are used to model and render data of different modalities. In this paper, we present a new endoscopy system for ... -
Skeletal Images as Visual Cues in Graph Visualization
(Springer and The Eurographics Association, 1999)The problem of graph layout and drawing is fundamental to many approaches to the visualization of relational information structures. As the data set grows, the visualization problem is compounded by the need to reconcile ... -
A Methodology for Comparing Direct Volume Rendering Algorithms Using a Projection-Based Data Level Approach
(Springer and The Eurographics Association, 1999)Identifying and visualizing uncertainty together with the data is a well recognized problem. One of the culprits that introduce uncertainty in the visualization pipeline is the visualization algorithm itself. Uncertainties ... -
Efficiently Rendering Large Volume Data Using Texture Mapping Hardware
(Springer and The Eurographics Association, 1999)Volume rendering with texture mapping hardware is a fast volume rendering method available on high-end workstations. However, limited texture memory often prevents the method from being used to render large volume data ... -
A Comparison of Error Indicators for Multilevel Visualization on Nested Grids
(Springer and The Eurographics Association, 1999)Multiresolution visualization methods have recently become an indispensable ingredient of real time interactive post processing. Here local error indicators serve as criteria where to refine the data representation on the ... -
A Client-side Approach towards Platform Independent Molecular Visualization over the World Wide Web
(Springer and The Eurographics Association, 1999)A web-based, entirely platform independent Molecular Visualization System has been developed using state of the Internet programming techniques. This system offers the visualization of various molecular models, molecular ... -
Attribute-Based Feature Tracking
(Springer and The Eurographics Association, 1999)Visualization of time-dependent data is an enormous task because of the vast amount of data involved. However, most of the time the scientist is mainly interested in the evolution of certain features. Therefore, it suffices ... -
Geodesic Flow on Polyhedral Surfaces
(Springer and The Eurographics Association, 1999)On a curved surface the front of a point wave evolves in concentric circles which start to overlap and branch after a certain time. This evolution is described by the geodesic flow and helps us to understand the geometry ... -
Exploring Instationary Fluid Flows by Interactive Volume Movies
(Springer and The Eurographics Association, 1999)Volume rendering offers the unique ability to represent inner object data and to realize enclosed structures ""at first glance"". Unlike software-based methods, the use of more and more available specialpurpose hardware ... -
Fast Volume Rotation using Binary Shear-Warp Factorization
(Springer and The Eurographics Association, 1999)This paper presents a fast volume rotation technique based on binary shear-warp factorization. Unlike many acceleration algorithms this method does not trade image quality for speed and does not require any specialized ... -
Internet-Based Front-End to Network Simulator
(Springer and The Eurographics Association, 1999)We present a Java-based interactive visual interface to network simulators. Having successfully incorporated network visualization technologies, our system provides an effective front-end interface supporting real time ... -
Geometric Methods for Vortex Extraction
(Springer and The Eurographics Association, 1999)This paper presents two vortex detection methods which are based on the geometric properties of streamlines. Unlike traditional vortex detection methods, which are based on point-samples of physical quantities, one of our ... -
Interactive Direct Volume Rendering of Time-Varying Data
(Springer and The Eurographics Association, 1999)Previous efforts aimed at improving direct volume rendering performance have focused largely on time-invariant, 3D data. Little work has been done in the area of interactive direct volume rendering of timevarying data, ... -
Efficient Ray Intersection for Visualization and Navigation of Global Terrain using Spheroidal Height-Augmented Quadtrees
(Springer and The Eurographics Association, 1999)We present an algorithm for efficiently computing ray intersections with multi-resolution global terrain partitioned by spheroidal height-augmented quadtrees. While previous methods support terrain defined on a Cartesian ... -
Advances in Quality Control of Intraoperative Radiotherapy
(Springer and The Eurographics Association, 1999)Intraoperative radiotherapy is the kind of radiotherapy where the remains of a surgically not completely removed tumour are irradiated at the open situ of the patient. The current main drawback of this radiotherapy is the ... -
Analysis and Visualization of the Brain Shift Phenomenon in Neurosurgery
(Springer and The Eurographics Association, 1999)In this paper we present a method for analyzing the brain shift. The brain shift is a brain deformation phenomenon, that occurs during surgical operations on the opened head. This deformation makes navigation within the ...
