Further, it can also ... http://vgtc.org/wpmu/vis09/2009/10/10/markerless-view-independent-registration-of-multiple-distorted-projectors-on-extruded-surfaces-using-an-uncalibrated-camera/ Authors Maarten H.

Roerdink Tobias Isenberg DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.138 Abstract We present a technique for the illustrative rendering of 3D line data at interactive frame rates. We create depth-dependent halos around lines to emphasize tight line bundles while less structured lines are de-emphasized. Moreover, the depth-dependent halos combined with depth cueing via ... http://vgtc.org/wpmu/vis09/2009/10/10/depth-dependent-halos-illustrative-rendering-of-dense-line-data/ Authors Gustavo M.

This has a significant impact on their private and professional lives. We present a physiologically-based model for simulating ... http://vgtc.org/wpmu/vis09/2009/10/10/a-physiologically-based-model-for-simulation-of-color-vision-deficiency-2/ Authors Gustavo M.

However, obtaining a semi-transparent result with the layers clearly revealed is difficult and may involve tedious adjustment on opacity and other rendering parameters. Furthermore, the visual ... http://vgtc.org/wpmu/vis09/2009/10/10/perception-based-transparency-optimization-for-direct-volume-rendering/ Authors Johnson Chuang Daniel Weiskopf Torsten Möller DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.150 Download Slides Abstract We propose a new perception-guided compositing operator for color blending. The operator maintains the same rules for achromatic compositing as standard operators (such as the over operator), but it modifies the computation of the chromatic channels. Chromatic compositing aims at preserving the hue of the ... http://vgtc.org/wpmu/vis09/2009/10/10/hue-preserving-color-blending/ Authors Hari Krishnan Christoph Garth Kenneth I. Joy DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.190 Download Slides Abstract Time and streak surfaces are ideal tools to illustrate time-varying vector ?elds since they directly appeal to the intuition about coherently moving particles. However, ef?cient generation of high-quality time and streak surfaces for complex, large and time-varying vector ?eld data has been elusive due ... http://vgtc.org/wpmu/vis09/2009/10/10/time-and-streak-surfaces-for-flow-visualization-in-large-time-varying-data-sets/ Authors Kai Bürger Florian Ferstl Holger Theisel Rüdiger Westermann DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.154 Download Slides Abstract In this paper we present techniques for the visualization of unsteady flows using streak surfaces, which allow for the first time an adaptive integration and rendering of such surfaces in real-time. The techniques consist of two main components, which are both realized on the ... http://vgtc.org/wpmu/vis09/2009/10/10/interactive-streak-surface-visualization-on-the-gpu/
