    • Adding a scalar value to texture-based vector field representations by local contrast analysis 

      Sanna, A.; Zunino, C.; Montrucchio, B.; Montuschi, P. (The Eurographics Association, 2002)
      Several algorithms can effectively represent vector fields by texture-based representations, visualizing at most all information on the field: direction, orientation, and local magnitude. An open problem still remains the ...

    • Secondary Task Display Attributes - Optimizing Visualizations for Cognitive Task Suitability and Interference Avoidance 

      Chewar, C. M.; McCrickard, D. Scott; Ndiwalana, Ali; North, Chris; Pryor, Jon; Tessendorf, David (The Eurographics Association, 2002)
      We found that established display design guidelines for focal images cannot be extended to images displayed as a secondary task in a dual-task situation. This paper describes an experiment that determines a new ordering ...

    • Shear-Warp Deluxe: The Shear-Warp Algorithm Revisited 

      Sweeney, Jon; Mueller, Klaus (The Eurographics Association, 2002)
      Despite continued advances in volume rendering technology, the Shear-Warp algorithm, although conceived as early as 1994, still remains the world s fastest purely software-based volume rendering algorithm. The impressive ...

    • AUFLIC: An Accelerated Algorithm For Unsteady Flow Line Integral Convolution 

      Liu, ZhanPing; II, Robert James Moorhead (The Eurographics Association, 2002)
      UFLIC (Unsteady Flow Line Integral Convolution) is an effective texture synthesis technique to visualize unsteady flow with enhanced temporal coherence, but it is time-consuming to generate. This paper presents an accelerated ...

    • A Continuous Skeletonization Method Based on Level Sets 

      Rumpf, Martin; Telea, Alexandru (The Eurographics Association, 2002)
      A robust and efficient method in 2D and 3D for the calculation of skeletons for arbitrary objects is presented. The method is based on the calculation of the distance function with respect to the object boundary. This is ...

    • A Novel Approach To Vortex Core Region Detection 

      Jiang, Ming; Machiraju, Raghu; Thompson, David (The Eurographics Association, 2002)
      In this paper we present a simple and efficient vortex core region detection algorithm based on ideas derived from combinatorial topology. These ideas originated from Sperner s lemma, which by itself is of little value to ...

    • Octreemizer: A Hierarchical Approach for Interactive Roaming Through Very Large Volumes
