    • 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 ...
