    • 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 ...

    • A Generic Solution for Hardware-Accelerated Remote Visualization 

      Stegmaier, Simon; Magallón, Marcelo; Ertl, Thomas (The Eurographics Association, 2002)
      This paper presents a generic solution for hardware-accelerated remote visualization that works transparently for all OpenGL-based applications and OpenGL-based scene graphs. Universality is achieved by taking advantage ...

    • Cell-Based First-Hit Ray Casting 

      Neubauer, A.; Mroz, L.; Hauser, H.; Wegenkittl, R. (The Eurographics Association, 2002)
      Cell-based first-hit ray casting is a new technique for fast perspective volume visualization. This technique, based on the well known ray casting algorithm, performs iso-surfacing and supports interactive threshold ...

    • Interactive Previewing for Transfer Function Specification in Volume Rendering 

      Botha, Charl P.; Post, Frits H. (The Eurographics Association, 2002)
      This paper presents a new technique for supplying meaningful visual feedback during direct volume rendering transfer function specification. The technique uses meta-data calculated during a pre-processing step to generate ...

    • Comparison of Morphological Pyramids for Multiresolution MIP Volume Rendering 

      Roerdink, Jos B.T.M. (The Eurographics Association, 2002)
      We recently proposed a multiresolution representation for maximum intensity projection (MIP) volume rendering based on morphological adjunction pyramids which allow progressive refinement and have the property of perfect ...

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

      Plate, John; Tirtasana, Michael; Carmona, Rhadamés; Fröhlich, Bernd (The Eurographics Association, 2002)
      We have developed a hierarchical paging scheme for handling very large volumetric data sets at interactive frame rates. Our system trades texture resolution for speed and uses effective prediction strategies. We have tested ...

    • 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 ...

    • 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 ...

    • Interactive Visualization and Steering of CFD Simulations 

      Kreylos, O.; Tesdall, A. M.; Hamanny, B.; Hunter, J. K.; Joy, K. I. (The Eurographics Association, 2002)
      We describe a system that supports real-time interactive visualization of computational fluid dynamics (CFD) simulations. The system allows a user to place and manipulate visualization primitives, such as isolines and ...

    • STATISTICAL COMPUTATION OF SALIENT ISO-VALUES 

      Tenginakai, Shivaraj; Machiraju, Raghu (The Eurographics Association, 2002)
      Detection of the salient iso-values in a volume dataset is often the first step towards its exploration. An error-and-trail approach is often used; new semi-automatic techniques either make assumptions about their data [4] ...

    • Parallel and Out-of-core View-dependent Isocontour Visualization Using Random Data Distribution 

      Zhang, Xiaoyu; Bajaj, Chandrajit; Ramachandran, Vijaya (The Eurographics Association, 2002)
      In this paper we describe a parallel and out-of-core view-dependent isocontour visualization algorithm that efficiently extracts and renders the visible portions of an isosurface from large datasets. The algorithm first ...
