    • Parallel BVH Construction using Progressive Hierarchical Refinement 

      Hendrich, Jakub; Meister, Daniel; Bittner, Jiří (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose a novel algorithm for construction of bounding volume hierarchies (BVHs) for multi-core CPU architectures. The algorithm constructs the BVH by a divisive top-down approach using a progressively refined cut of ...
    • Parallel Reinsertion for Bounding Volume Hierarchy Optimization 

      Meister, Daniel; Bittner, Jiří (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We present a novel highly parallel method for optimizing bounding volume hierarchies (BVH) targeting contemporary GPU architectures. The core of our method is based on the insertion-based BVH optimization that is known to ...
    • Ray Classification for Accelerated BVH Traversal 

      Hendrich, Jakub; Pospíšil, Adam; Meister, Daniel; Bittner, Jiří (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      For ray tracing based methods, traversing a hierarchical acceleration data structure takes up a substantial portion of the total rendering time. We propose an additional data structure which cuts off large parts of the ...
    • T-SAH: Animation Optimized Bounding Volume Hierarchies 

      Bittner, Jirí; Meister, Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We propose a method for creating a bounding volume hierarchy (BVH) that is optimized for all frames of a given animated scene. The method is based on a novel extension of surface area heuristic to temporal domain (T-SAH). ...
