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 ...
Adaptive Temporal Antialiasing
(ACM, 2018)
We introduce a pragmatic algorithm for real-time adaptive supersampling in games. It extends temporal antialiasing of rasterized images with adaptive ray tracing, and conforms to the constraints of a commercial game engine ...
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 ...
