    • Real-Time Concurrent Linked List Construction on the GPU 

      Yang, Jason C.; Hensley, Justin; Gruen, Holger; Thibieroz, Nicolas (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We introduce a method to dynamically construct highly concurrent linked lists on modern graphics processors. Once constructed, these data structures can be used to implement a host of algorithms useful in creating complex ...

    • SafeGI: Type Checking to Improve Correctness in Rendering System Implementation 

      Ou, Jiawei; Pellacini, Fabio (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Historically, rendering system development has been mainly focused on improving the numerical accuracy of the rendering algorithms and their runtime efficiency. In this paper, we propose a method to improve the correctness ...

    • Semi-Stochastic Tilings for Example-Based Texture Synthesis 

      Schloemer, Thomas; Deussen, Oliver (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We investigate semi-stochastic tilings based on Wang or corner tiles for the real-time synthesis of example-based textures. In particular, we propose two new tiling approaches: (1) to replace stochastic tilings with ...

    • Sparsely Precomputing The Light Transport Matrix for Real-Time Rendering 

      Huang, Fu-Chung; Ramamoorthi, Ravi (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Precomputation-based methods have enabled real-time rendering with natural illumination, all-frequency shadows, and global illumination. However, a major bottleneck is the precomputation time, that can take hours to days. ...

    • Spectralization: Reconstructing spectra from sparse data 

      Rump, Martin; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Traditional RGB reflectance and light data suffers from the problem of metamerism and is not suitable for rendering purposes where exact color reproduction under many different lighting conditions is needed. Nowadays many ...

    • Two Methods for Fast Ray-Cast Ambient Occlusion 

      Laine, Samuli; Karras, Tero (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Ambient occlusion has proven to be a useful tool for producing realistic images, both in offline rendering and interactive applications. In production rendering, ambient occlusion is typically computed by casting a large ...

    • Visibility Editing For All-Frequency Shadow Design 

      Obert, Juraj; Pellacini, Fabio; Pattanaik, Sumanta (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present an approach for editing shadows in all-frequency lighting environments. To support artistic control, we propose to decouple shadowing from lighting and focus on providing intuitive controls to edit the former. ...
