    • Rendering Soft Shadows using Multilayered Shadow Fins 

      Cai, Xiao-Hua; Jia, Yun-Tao; Wang, Xi; Hu, Shi-Min; Martin, Ralph R. (The Eurographics Association and Blackwell Publishing Ltd., 2006)
      Generating soft shadows in real time is difficult. Exact methods (such as ray tracing, and multiple light source simulation) are too slow, while approximate methods often overestimate the umbra regions. In this paper, we ...

    • Speed-up Technique for a Local Automatic Colour Equalization Model 

      Artusi, A.; Gatta, C.; Marini, D.; Purgathofer, W.; Rizzi, A. (The Eurographics Association and Blackwell Publishing Ltd., 2006)
      In this paper we propose a speed-up technique for a local automatic colour equalization operator derived from a model of the human vision system. This method is characterized by local and global filtering effects, that ...

      Mudge, Mark; Ryan, Nick; Scopigno, Roberto (The Eurographics Association and Blackwell Publishing Ltd., 2006)

    • Virtual Reality Course-A Natural Enrichment of Computer Graphics Classes 

      Zara, J. (The Eurographics Association and Blackwell Publishing Ltd., 2006)
      This paper shows how the Virtual Reality (VR) course can naturally extend and practice a wide range of Computer Graphics (CG) principles and programming techniques. Thanks to real-time processing requirements, attention ...

    • A Weighted Error Metric and Optimization Method for Antialiasing Patterns 

      Laine, S.; Aila, T. (The Eurographics Association and Blackwell Publishing Ltd., 2006)
      Displaying a synthetic image on a computer display requires determining the colors of individual pixels. To avoid aliasing, multiple samples of the image can be taken per pixel, after which the color of a pixel may be ...
