    • Fast Generation of Approximate Blue Noise Point Sets 

      Kalantari, Nima Khademi; Sen, Pradeep (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Poisson-disk sampling is a popular sampling method because of its blue noise power spectrum, but generation of these samples is computationally very expensive. In this paper, we propose an efficient method for fast generation ...

    • Parallel Blue-noise Sampling by Constrained Farthest Point Optimization 

      Chen, Renjie; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We describe a fast sampling algorithm for generating uniformly-distributed point patterns with good blue noise characteristics. The method, based on constrained farthest point optimization, is provably optimal and may be ...

    • PixelPie: Maximal Poisson-disk Sampling with Rasterization 

      Ip, Cheuk Yiu; Yalc, M. Adil; Luebke, David; Varshney, Amitabh (ACM, 2013)
      We present PixelPie, a highly parallel geometric formulation of the Poisson-disk sampling problem on the graphics pipeline. Traditionally, generating a distribution by throwing darts and removing conflicts has been viewed ...

    • View-independent Environment Maps 

      Heidrich, Wolfgang; Seidel, Hans-Peter (The Eurographics Association, 1998)
      Environment maps are widely used for approximating reflections in hardware-accelerated rendering applications. Unfortunately, the parameterizations for environment maps used in today s graphics hardware severely undersample ...
