    A Client-side Approach towards Platform Independent Molecular Visualization over the World Wide Web 

    Bender, Michael; Hagen, Hans; Seck, Axel (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 ...

    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, ...

    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 ...

    Adaptive Volume Construction from Ultrasound Images of a Human Heart 

    Reis, Gerd; Bertram, Martin; Lengen, Rolf H. van; Hagen, Hans (The Eurographics Association, 2004)
    We present a volume modelling approach based on sequences of two-dimensional ultrasound images. Though generally applicable to arbitrary freehand ultrasound, our method is designed for the reconstruction of timevarying ...

    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 ...

    Volume Deformations in Grid-Less Flow Simulations 

    Obermaier, Harald; Hering-Bertram, Martin; Kuhnert, Jörg; Hagen, Hans (The Eurographics Association and Blackwell Publishing Ltd., 2009)
    Abstract This paper presents a novel method for the extraction and visualization of volume deformations in grid-less point based flow simulations. Our primary goals are the segmentation of different paths through a mixing ...

    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 ...

    Non-manifold Mesh Extraction from Time-varying Segmented Volumes used for Modeling a Human Heart 

    Bertram, Martin; Reis, Gerd; Lengen, Rolf H. van; Köhn, Sascha; Hagen, Hans (The Eurographics Association, 2005)
    We present a new algorithm extracting and fairing surfaces from segmented volumes composed of multiple materials. In a first pass, the material boundaries in the volume are smoothed considering signed distance functions ...

    Adaptive Smooth Scattered-data Approximation for Large-scale Terrain Visualization 

    Bertram, Martin; Tricoche, Xavier; Hagen, Hans (The Eurographics Association, 2003)
    We present a fast method that adaptively approximates large-scale functional scattered data sets with hierarchical B-splines. The scheme is memory efficient, easy to implement and produces smooth surfaces. It combines ...
