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 ...
Extended Morton Codes for High Performance Bounding Volume Hierarchy Construction
(ACM, 2017)
We propose an extension to the Morton codes used for spatial sorting of scene primitives. e extended Morton codes increase the coherency of the clusters resulting from the object sorting and work be er for non-uniform ...
