    • Three-dimensional Reconstruction and Visualization of the Cerebral Cortex in Primates 

      Demelio, Sergio; Bettio, Fabio; Gobbetti, Enrico; Luppino, Giuseppe (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 ...
    • 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 ...
    • Vector and Tensor Field Topology Simplification on Irregular Grids 

      Tricoche, Xavier; Scheuermann, Gerik; Hagen, Hans; Clauss, Stefan (The Eurographics Association, 2001)
      Topology-based visualization of planar turbulent flows results in visual clutter due to the presence of numerous features of very small scale. In this paper, we attack this problem with a topology simplification method for ...
    • Virtual Colon Flattening 

      Bartroli, A. Vilanova; R.Wegenkittl,; König, A.; Gröller, E.; Sorantin, E. (The Eurographics Association, 2001)
      We present a new method to visualize virtual endoscopic views. We propose to flatten the organ by the direct projection of the surface onto a set of cylinders. Two sampling strategies are presented and the introduced ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
