    • Points Reloaded: Point-Based Rendering Revisited 

      Sainz, Miguel; Pajarola, Renato; Lario, Roberto (The Eurographics Association, 2004)
      The increasing popularity of points as rendering primitives has led to a variety of different rendering algorithms, and in particular the different implementations compare like apples to oranges. In this paper we revisit ...
