    • Fullsphere Irradiance Factorization for Real-Time All-Frequency Illumination for Dynamic Scenes 

      Michael, D.; Chrysanthou, Y. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Computation of illumination with soft-shadows from all-frequency environment maps, is a computationally expensive process. Use of pre-computation add the limitation that receiver s geometry must be known in advance, since ...

    • High-Quality Screen-Space Ambient Occlusion using Temporal Coherence 

      Mattausch, Oliver; Scherzer, Daniel; Wimmer, Michael (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Ambient occlusion is a cheap but effective approximation of global illumination. Recently, screen-space ambient occlusion (SSAO) methods, which sample the frame buffer as a discretization of the scene geometry, have become ...

    • Progressive Point-Light-Based Global Illumination 

      Dammertz, H.; Keller, A.; Lensch, H. P. A. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a physically based progressive global illumination system that is capable of simulating complex lighting situations robustly by efficiently using both light and eye paths. Specifically, we combine three distinct ...

    • Teaching Quaternions is not Complex 

      McDonald, J. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Quaternions are used in many fields of science and computing, but teaching them remains challenging. Students can have a great deal of trouble understanding essentially what quaternions are and how they can represent ...

    • 3D Surface Reconstruction Using a Generalized Distance Function 

      Poranne, R.; Gotsman, C.; Keren, D. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We define a generalized distance function on an unoriented 3D point set and describe how it may be used to reconstruct a surface approximating these points. This distance function is shown to be a Mahalanobis distance in ...

    • A Survey of Procedural Noise Functions 

      Lagae, A.; Lefebvre, S.; Cook, R.; DeRose, T.; Drettakis, G.; Ebert, D.S.; Lewis, J.P.; Perlin, K.; Zwicker, M. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Procedural noise functions are widely used in computer graphics, from off-line rendering in movie production to interactive video games. The ability to add complex and intricate details at low memory and authoring cost is ...

    • Generalized Use of Non-Terminal Symbols for Procedural Modeling 

      Krecklau, L.; Pavic, D.; Kobbelt, L. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present the new procedural modeling language, (Generalized Grammar), which adapts various concepts from general purpose programming languages to provide high descriptive power with well-defined semantics and a simple ...
