    • Geodesic Flow on Polyhedral Surfaces 

      Polthier, Konrad; Schmies, Markus (Springer and The Eurographics Association, 1999)
      On a curved surface the front of a point wave evolves in concentric circles which start to overlap and branch after a certain time. This evolution is described by the geodesic flow and helps us to understand the geometry ...

    • Exploring Instationary Fluid Flows by Interactive Volume Movies 

      Glau, Thomas (Springer and The Eurographics Association, 1999)
      Volume rendering offers the unique ability to represent inner object data and to realize enclosed structures ""at first glance"". Unlike software-based methods, the use of more and more available specialpurpose hardware ...

    • Fast Volume Rotation using Binary Shear-Warp Factorization 

      Csebfalvi, Balazs (Springer and The Eurographics Association, 1999)
      This paper presents a fast volume rotation technique based on binary shear-warp factorization. Unlike many acceleration algorithms this method does not trade image quality for speed and does not require any specialized ...

    • Internet-Based Front-End to Network Simulator 

      He, Taosong (Springer and The Eurographics Association, 1999)
      We present a Java-based interactive visual interface to network simulators. Having successfully incorporated network visualization technologies, our system provides an effective front-end interface supporting real time ...

    • Geometric Methods for Vortex Extraction 

      Sadarjoen, I. Ari; Post, Frits H. (Springer and The Eurographics Association, 1999)
      This paper presents two vortex detection methods which are based on the geometric properties of streamlines. Unlike traditional vortex detection methods, which are based on point-samples of physical quantities, one of our ...

    • Interactive Direct Volume Rendering of Time-Varying Data 

      Clyne, John; Dennis, John M. (Springer and The Eurographics Association, 1999)
      Previous efforts aimed at improving direct volume rendering performance have focused largely on time-invariant, 3D data. Little work has been done in the area of interactive direct volume rendering of timevarying data, ...

    • Efficient Ray Intersection for Visualization and Navigation of Global Terrain using Spheroidal Height-Augmented Quadtrees 

      Wartell, Zachary; Ribarsky, William; Hodges, Larry (Springer and The Eurographics Association, 1999)
      We present an algorithm for efficiently computing ray intersections with multi-resolution global terrain partitioned by spheroidal height-augmented quadtrees. While previous methods support terrain defined on a Cartesian ...

    • Advances in Quality Control of Intraoperative Radiotherapy 

      Walter, Stefan; Straßmann, Gerd; Schmitt, Marco (Springer and The Eurographics Association, 1999)
      Intraoperative radiotherapy is the kind of radiotherapy where the remains of a surgically not completely removed tumour are irradiated at the open situ of the patient. The current main drawback of this radiotherapy is the ...

    • Analysis and Visualization of the Brain Shift Phenomenon in Neurosurgery 

      Lürig, C.; Hastreiter, P.; Nimsky, C.; Ertl, T. (Springer and The Eurographics Association, 1999)
      In this paper we present a method for analyzing the brain shift. The brain shift is a brain deformation phenomenon, that occurs during surgical operations on the opened head. This deformation makes navigation within the ...
