    • A Methodology for Comparing Direct Volume Rendering Algorithms Using a Projection-Based Data Level Approach 

      Kim, Kwansik; Pang, Alex (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 ...
    • New Approaches for Particle Tracing on Sparse Grids 

      Teitzel, Christian; Ertl, Thomas (Springer and The Eurographics Association, 1999)
      Flow visualization tools based on particle methods continue to be an important utility of flow simulation. Additionally, sparse grids are of increasing interest in numerical simulations. In [14] we presented the advontages ...
    • On Simulated Annealing and the Construction of Linear Spline Approximations for Scattered Data 

      Kreylos, Oliver; Hamann, Bernd (Springer and The Eurographics Association, 1999)
      We describe a method to create optimal linear spline approximations to arbitrary functions of one or two variables, given as scattered data without known connectivity.We start with an initial approximation consisting of a ...
    • Parallel Multipipe Rendering for Very Large Isosurface Visualization 

      Udeshi, Tushar; Hansen, Charles D. (Springer and The Eurographics Association, 1999)
      In exploratory scientific visualization, isosurfaces are typi- cally created with an explicit polygonal representation for the surface using a technique such as Marching Cubes. For even moderate data sets, Marchching Cubes ...
    • Parallel Ray Casting of Visible Human on Distributed Memory Architectures 

      Bajaj, Chandrajit; Ihm, Insung; Koo, Gee-bum; Park, Sanghun (Springer and The Eurographics Association, 1999)
      This paper proposes a new parallel ray-casting scheme for very large volume data on distributed-memory architectures. Our method, based on data compression, attempts to enhance the speedup of parallel rendering by quickly ...
    • Procedural Shape Generation for Multi-dimensional Data Visualization 

      Ebert, David S.; Rohrer, Randall M.; Shaw, Christopher D.; Panda, Pradyut; Kulda, James M.; Roberts, D. Aaron (Springer and The Eurographics Association, 1999)
      Visualization of multi-dimensional data is a challenging task. The goal is not the display of multiple data dimensions, but user comprehension of the multi-dimensional data. This paper explores several techniques for ...
    • Real-Time Maximum Intensity Projection 

      Mroz, Lukas; König, Andreas; Gröller, Eduard (Springer and The Eurographics Association, 1999)
      Maximum Intensity Projection (MIP) is a volume rendering technique which is used to extract high-intensity structures from volumetric data. At each pixel the highest data value encountered along the corresponding viewing ...
    • Skeletal Images as Visual Cues in Graph Visualization 

      Herman, I.; Marshall, M.S.; Melancon, G.; Duke, D.J.; Delest, M.; Domenger, J.-P. (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 ...
    • VISSION: An Object Oriented Dataflow System for Simulation and Visualization 

      Telea, Alexandru; Wijk, Jarke J. van (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 by Examples: Mapping Data to Visual Representations using Few Correspondences 

      Alexa, Marc; Müller, Wolfgang (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 Global Flow Structures Using Multiple Levels of Topology 

      Leeuw, Wim de; Liere, Robert van (Springer and The Eurographics Association, 1999)
      The technique for visualizing topological information in fluid flows is well known. However, when the technique is used in complex and information rich data sets, the result will be a cluttered image which is difficult to ...
    • Visualization of Grinding Processes 

      Fiege, Markus; Scheuermann, Gerik; Münchhofen, Michael; Hagen, Hans (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 ...
    • Visualization of Molecules with Positional Uncertainty 

      Rheingans, Penny; Joshi, Shrikant (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 ...
    • VIVENDI - A Virtual Endoscopy System for Virtual Medicine 

      Bartz, Dirk; Skalej, Martin (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 ...
    • Where Weather Meets the Eye - A Case Study on a Wide Range of Meteorological Visualizations for Diverse Audiences 

      Haase, H.; Bock, M.; Hergenröther, E.; Knöpfle, C.; Koppert, H.-J.; Schröder, F.; Trembilski, A.; Weidenhausen, J. (Springer and The Eurographics Association, 1999)
      Sophisticated visualisation enables experts as well as lay persons to extract knowledge from complex data. This is particularly true for visualising the massive amounts of data involved in meteorological observations and ...
