Efficient Incoherent Ray Traversal on GPUs Through Compressed Wide BVHs
(ACM, 2017)
We present a GPU-based ray traversal algorithm that operates on compressed wide BVHs and maintains the traversal stack in a compressed format. Our method reduces the amount of memory traffic significantly, which translates ...
Interactive Stable Ray Tracing
(ACM, 2017)
Interactive ray tracing applications running on commodity hard- ware can su er from objectionable temporal artifacts due to a low sample count. We introduce stable ray tracing, a technique that improves temporal stability ...
CPU-Style SIMD Ray Traversal on GPUs
(ACM, 2018)
In this paper we describe and evaluate an implementation of CPUstyle SIMD ray traversal on the GPU. We show how spreading moderately wide BVHs (up to a branching factor of eight) across multiple threads in a warp can improve ...
Ray/Ribbon Intersections
(ACM Association for Computing Machinery, 2022)
We present a new ray tracing primitive-a curved ribbon, which is embedded inside a ruled surface. We describe two such surfaces. Ribbons inside doubly ruled bilinear patches can be intersected by solving a quadratic equation. ...
