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 ...
Timeline Scheduling for Out-of-Core Ray Batching
(ACM, 2017)
We present a timeline based scheduling method for Monte Carlo ray tracing of out-of-core models on distributed memory clusters. We abstract different setups of various compute and memory devices into a graph-based ...
Dual Streaming for Hardware-Accelerated Ray Tracing
(ACM, 2017)
Hardware acceleration for ray tracing has been a topic of great interest in computer graphics. However, even with proposed custom hardware, the inherent irregularity in the memory access pattern of ray tracing has limited ...
Spatiotemporal Variance-Guided Filtering: Real-Time Reconstruction for Path Traced Global Illumination
(ACM, 2017)
We introduce a reconstruction algorithm that generates a tempo- rally stable sequence of images from one path-per-pixel global illumination. To handle such noisy input, we use temporal accu- mulation to increase the e ...
Vectorized Production Path Tracing
(ACM, 2017)
This paper presents MoonRay, a high performance production rendering architecture using Monte Carlo path tracing developed at DreamWorks Animation. MoonRay is the first production path tracer, to our knowledge, designed ...
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 ...
Accelerated Single Ray Tracing for Wide Vector Units
(ACM, 2017)
Utilizing the vector units of current processors for ray tracing single rays through Bounding Volume Hierarchies has been accomplished by increasing the branching factor of the acceleration structure to match the vector ...
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 ...
STBVH: A Spatial-Temporal BVH for Efficient Multi-Segment Motion Blur
(ACM, 2017)
We present the STBVH, a newapproach for rendering multi-segment motion blur using a bounding volume hierarchy (BVH) that stores both spatial linearly interpolated bounds and temporal bounds. The approach is designed for ...
Exploiting Budan-Fourier and Vincent's Theorems for Ray Tracing 3D Bézier Curves
(ACM, 2017)
We present a new approach to finding ray-cubic Bézier curve intersections by leveraging recent achievements in polynomial studies. Compared with the state-of-the-art adaptive linearization, it increases performance by 5-50 ...
