    • Topology-Based Visualization of Time-Dependent 2D Vector Fields 

      Tricoche, Xavier; Scheuermann, Gerik; Hagen, Hans (The Eurographics Association, 2001)
      Topology-based methods have been successfully applied to the visualization of instantaneous planar vector fields. In this paper, we present the topology-based visualization of time-dependent 2D flows. Our method tracks ...

      Coomans, Marc; Timmermans, Harry (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 

      Li, Xinyue; Shen, Han-Wei (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 ...

    • Visualization of directed associations in e-commerce transaction data 

      Hao, Ming C.; Dayal, Umeshwar; Hsu, Meichun; Sprenger, Thomas; Gross, Markus H. (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 ...

    • Automotive Soiling Simulation Based On Massive Particle Tracing 

      Roettger, Stefan; Schulz, Martin; Bartelheimer, Wolf; Ertl, Thomas (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 

      Harding, Chris; Kakadiaris, Ioannis A.; Casey, John F.; Loftin, R. Bowen (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 ...

    • Visualization of Thermal Flows in an Automotive Cabin with Volume Rendering Method 

      Ono, Kenji; Matsumoto, Hideki; Himeno, Ryutaro (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 ...

    • Preserving the Mental Map using Foresighted Layout 

      Diel, Stepahn; Görg, Carsten; Kerren, Andreas (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 ...

    • Volume Rendering Data with Uncertainty Information 

      Djurcilov, Suzana; Kim, Kwansik; Lermusiaux, Pierre F. J.; Pang, Alex (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 ...

    • Voxel Column Culling: Occlusion Culling for Large Terrain Models 

      Zaugg, Brian; Egbert, Parris K. (The Eurographics Association, 2001)
      We present Voxel Column Culling, an occlusion culling algorithm for real-time rendering of large terrain models. This technique can greatly reduce the number of polygons that must be rendered every frame, allowing a larger ...

    • A Hardware-Assisted Visibility-Ordering Algorithm With Applications To Volume Rendering 

      Krishnan, Shankar; Silva, Cláudio T.; Wei, Bin (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 

      Liu, Zhiyan; Finkelstein, Adam; Li, Kai (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 ...

    • Visualization of Generalized Voronoi Diagrams 

      Telea, Alexandru; Wijk, Jarke J. van (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 ...

    • Multiresolution Maximum Intensity Volume Rendering by Morphological Pyramids 

      Roerdink, Jos B.T.M. (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 ...

    • Subdivision Surfaces for Scattered-data Approximation 

      Bertram, Martin; Hagen, Hans (The Eurographics Association, 2001)
