    • Optimized Route for Crowd Evacuation 

      Wong, Sai-Keung; Wang, Yu-Shuen; Tang, Pao-Kun; Tsai, Tsung-Yu (The Eurographics Association, 2016)
      An evacuation plan helps people move away from an area or a building. To achieve a fast evacuation, we present an algorithm to compute the optimal route for each local region. The idea is to reduce congestion and to maximize ...
    • Optimized Sampling for View Interpolation in Light Fields with Overlapping Patches 

      Schedl, David C.; Bimber, Oliver (The Eurographics Association, 2018)
      Optimized sampling masks that reduce the complexity of camera arrays while preserving the quality of light fields captured at high directional sampling resolution are presented. We propose a new quality metric that is based ...
    • An Optimized Soft Shadow Volume Algorithm with Real-Time Performance 

      Assarsson, Ulf; Dougherty, Michael; Mounier, Michael; Akenine-Möller, Tomas (The Eurographics Association, 2003)
      In this paper, we present several optimizations to our previously presented soft shadow volume algorithm. Our optimizations include tighter wedges, heavily optimized pixel shader code for both rectangular and spherical ...
    • OPTIMIZED SOFTWARE DISTRIBUTION IN SATELLITE GRAPHICS SYSTEMS 

      Cullmann, Norbert (The Eurographics Association, 1980)
      Interactive computer graphics requires satellite systems. The two software techniques used today with these systems ('fixed-function' and 'programmable satellite') showed to be unsatisfactory. This paper points out refined ...
    • Optimized Sub-Sampling of Point Sets for Surface Splatting 

      Wu, Jainhua; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Using surface splats as a rendering primitive has gained increasing attention recently due to its potential for high-performance and high-quality rendering of complex geometric models. However, as with any other rendering ...
    • Optimized Topological Surgery for Unfolding 3D Meshes
