We describe Embree, an open source ray tracing framework for x86 CPUs. Embree is
explicitly designed to achieve high performance in professional rendering environments in …

Ray tracing is an inherent part of photorealistic image synthesis algorithms. The problem of
ray tracing is to find the nearest intersection with a given ray and scene. Although this …

We discuss the mapping of elementary ray tracing operations---acceleration structure
traversal and primitive intersection---onto wide SIMD/SIMT machines. Our focus is on …

We present a novel approach to ray tracing execution on commodity graphics hardware
using CUDA. We decompose a standard ray tracing algorithm into several data‐parallel …

This paper proposes a massively parallel hardware architecture for efficient tracing of
incoherent rays, eg for global illumination. The general approach is centered around …

Arnold is a physically based renderer for feature-length animation and visual effects.
Conceived in an era of complex multi-pass rasterization-based workflows struggling to keep …

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 …

Ray‐traced global illumination (GI) is becoming widespread in production rendering but
incoherent secondary ray traversal limits practical rendering to scenes that fit in memory …

Virtual Reality (VR) places demanding requirements on the rendering pipeline: the
rendering is stereoscopic and the refresh rate should be as high as 95 Hz to make VR …

We propose a novel massively parallel construction algorithm for Bounding Volume
Hierarchies (BVHs) based on locally-ordered agglomerative clustering. Our method builds …
