    • Analysis of Sample Correlations for Monte Carlo Rendering 

      Singh, Gurprit; Öztireli, Cengiz; Ahmed, Abdalla G. M.; Coeurjolly, David; Subr, Kartic; Deussen, Oliver; Ostromoukhov, Victor; Ramamoorthi, Ravi; Jarosz, Wojciech (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Modern physically based rendering techniques critically depend on approximating integrals of high dimensional functions representing radiant light energy. Monte Carlo based integrators are the choice for complex scenes and ...
    • Capacity Constrained Voronoi Tessellation Revisited 

      Ahmed, Abdalla G. M.; Deussen, Oliver (The Eurographics Association, 2017)
      Capacity Constrained Voronoi Tessellation is an important concept that greatly influenced recent research on point sampling. The original concept was based on discretizing the sampled domain, and the algorithm was prohibitively ...
    • Colored AA Bitmaps 

      Ahmed, Abdalla G. M.; Deussen, Oliver (The Eurographics Association, 2017)
      AA Bitmaps are ornamental monochrome bitmaps. We present an algorithm for colorizing a certain family of AA Bitmaps that relies on modular arithmetics.
    • Sampling with Pinwheel Tiles 

      Ahmed, Abdalla G. M. (The Eurographics Association, 2019)
      We outline an adaptive sampling framework based on Conway's pinwheel tiles. It offers a unique feature that the generated tiles have infinite number of orientation angles, minimizing the strong auto-correlations found on ...
    • Voronoi Tree Maps with Circular Boundaries 

      Ahmed, Abdalla G. M. (The Eurographics Association, 2018)
      Voronoi tree maps are an important milestone in information visualization, representing a substantial advancement of the original tree maps concept. We address a less-studied variant of Voronoi tree maps that uses ...
