Improved Two-Level BVHs Using Partial Re-Braiding
(ACM, 2017)
We propose a novel approach for improving the quality of two-level BVHs (i.e., a two-level data structure that uses a top-level BVH built over second-level object BVHs). After building an individual, high-quality BVH for ...
Sub-triangle opacity masks for faster ray tracing of transparent objects
(ACM, 2020)
We propose an easy and simple-to-integrate approach to accelerate ray tracing of alpha-tested transparent geometry with a focus on Microsoft® DirectX® or Vulkan® ray tracing extensions. Pre-computed bit masks are used to ...
Compressed-Leaf Bounding Volume Hierarchies
(ACM, 2018)
We propose and evaluate what we call Compressed-Leaf Bounding Volume Hierarchies (CLBVH), which strike a balance between compressed and non-compressed BVH layouts. Our CLBVH layout introduces dedicated compressed multi-leaf ...
PLOC++ : Parallel Locally-Ordered Clustering for Bounding Volume Hierarchy Construction Revisited
(ACM Association for Computing Machinery, 2022)
We propose a novel version of the GPU-oriented massively parallel locally-ordered clustering (PLOC) algorithm for constructing bounding volume hierarchies (BVHs). Our method focuses on removing the weaknesses of the original ...
