    • Adaptive Sampling for On-The-Fly Ray Casting of Particle-based Fluids 

      Hochstetter, Hendrik; Orthmann, Jens; Kolb, Andreas (The Eurographics Association, 2016)
      We present a fast and accurate ray casting technique for unstructured and dynamic particle sets. Our technique focuses on efficient, high quality volume rendering of fluids for computer animation and scientific applications. ...
    • Bandwidth-Efficient BVH Layout for Incremental Hardware Traversal 

      Liktor, Gabor; Vaidyanathan, Karthik (The Eurographics Association, 2016)
      The memory footprint of bounding volume hierarchies (BVHs) can be significantly reduced using incremental encoding, which enables the coarse quantization of bounding volumes. However, this compression alone does not ...
    • DIRT: Deferred Image-based Ray Tracing 

      Vardis, Konstantinos; Vasilakis, Andreas-Alexandros; Papaioannou, Georgios (The Eurographics Association, 2016)
      We introduce a novel approach to image-space ray tracing ideally suited for the photorealistic synthesis of fully dynamic environments at interactive frame rates. Our method, designed entirely on the rasterization pipeline, ...
    • Efficient Stackless Hierarchy Traversal on GPUs with Backtracking in Constant Time 

      Binder, Nikolaus; Keller, Alexander (The Eurographics Association, 2016)
      The fastest acceleration schemes for ray tracing rely on traversing a bounding volume hierarchy (BVH) for efficient culling and use backtracking, which in the worst case may expose cost proportional to the depth of the ...
    • Filtering Distributions of Normals for Shading Antialiasing 

      Kaplanyan, Anton S.; Hill, Stephen; Patney, Anjul; Lefohn, Aaron (The Eurographics Association, 2016)
      High-frequency illumination effects, such as highly glossy highlights on curved surfaces, are challenging to render in a stable manner. Such features can be much smaller than the area of a pixel and carry a high amount of ...
    • Masked Software Occlusion Culling 

      Hasselgren, Jon; Andersson, Magnus; Akenine-Möller, Tomas (The Eurographics Association, 2016)
      Efficient occlusion culling in dynamic scenes is a very important topic to the game and real-time graphics community in order to accelerate rendering. We present a novel algorithm inspired by recent advances in depth culling ...
    • Photon Splatting Using a View-Sample Cluster Hierarchy 

      Moreau, Pierre; Sintorn, Erik; Kämpe, Viktor; Assarsson, Ulf; Doggett, Michael (The Eurographics Association, 2016)
      Splatting photons onto primary view samples, rather than gathering from a photon acceleration structure, can be a more efficient approach to evaluating the photon-density estimate in interactive applications, where the ...
    • Watertight Ray Traversal with Reduced Precision 

      Vaidyanathan, Karthik; Akenine-Möller, Tomas; Salvi, Marco (The Eurographics Association, 2016)
      Reduced precision bounding volume hierarchies and ray traversal can significantly improve the efficiency of ray tracing through low-cost dedicated hardware. A key approach to enabling reduced precision computations during ...
