    • 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 ...

    • 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 ...

    • Stream Surface Generation for Fluid Flow Solutions on Curvilinear Grids 

      Gelder, Allen Van (The Eurographics Association, 2001)
      A stream surface in a steady-state three-dimensional fluid flow vector field is a surface across which there is no flow. Stream surfaces can be useful for visualization because the amount of data presented in one visualization ...

    • 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 ...

    • 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 ...

    • Subdivision Surfaces for Scattered-data Approximation 

      Bertram, Martin; Hagen, Hans (The Eurographics Association, 2001)
      We propose a modified Loop subdivision surface scheme for the approximation of scattered data in the plane. Starting with a triangulated set of scattered data with associated function values, our scheme applies linear, ...

    • The Rendering of Unstructured Grids Revisited 

      Westermann, Rüdiger (The Eurographics Association, 2001)
      In this paper we propose a technique for resampling scalar fields given on unstructured tetrahedral grids. This technique takes advantage of hardware accelerated polygon rendering and 2D texture mapping and thus avoids any ...

    • Nonlinear Diffusion in Graphics Hardware 

      Rumpf, M.; Strzodka, R. (The Eurographics Association, 2001)
      Multiscale methods have proved to be successful tools in image denoising, edge enhancement and shape recovery. They are based on the numerical solution of a nonlinear diffusion problem where a noisy or damaged image which ...

    • 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 ...

    • Fast Multiresolution Extraction of Multiple Transparent Isosurfaces 

      Gerstner, Thomas (The Eurographics Association, 2001)
      In this paper, we present a multiresolution algorithm which is capable to render multiple transparent isosurfaces under real time constraints. To this end, the underlying 3D data set is covered with a hierarchical tetrahedral ...

    • Extraction of Crack-free Isosurfaces from Adaptive Mesh Refinement Data 

      Weber, Gunther H.; Kreylos, Oliver; Ligocki, Terry J.; Shalf, John M.; Hagen, Hans; Hamann, Bernd; Joy, Kenneth I. (The Eurographics Association, 2001)
      Adaptive mesh refinement (AMR) is a numerical simulation technique used in computational fluid dynamics (CFD). It permits the efficient simulation of phenomena characterized by substantially varying scales in complexity ...

    • 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 ...

    • Acquisition and Display of Real-Time Atmospheric Data on Terrain 

      Jiang, Tian-yue; Ribarsky, William; Wasilewski, Tony; Faust, Nickolas; Hannigan, Brendan; Parry, Mitchell (The Eurographics Association, 2001)
      This paper investigates the integrated acquisition, organization, and display of data from disparate sources, including the display of data acquired in real-time. In this case real-time acquisition and display refers to ...
