    • Sampled and Prefiltered Anti-Aliasing on Parallel Hardware 

      Thomas, Auzinger (2015-05)
      A fundamental task in computer graphics is the generation of two-dimensional images. Prominent examples are the conversion of text or three-dimensional scenes to formats that can be presented on a raster display. Such a ...
    • Sampling and Variance Analysis for Monte Carlo Integration in Spherical Domain 

      Singh, Gurprit (HAL, 2015-09)
      This dissertation introduces a theoretical framework to study different sampling patterns in the spherical domain and their effects in the evaluation of global illumination integrals. Evaluating illumination (light ...
    • Scalable Comparative Visualization 

      Schmidt, Johanna (2016-06-28)
      The comparison of two or more objects is getting an increasingly important task in data analysis. Visualization systems successively have to move from representing one phenomenon to allowing users to analyze several ...
