Ray tracing has long been a method of choice for off‐line rendering, but traditionally was too
slow for interactive use. With faster hardware and algorithmic improvements this has recently …

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 present two novel parallel algorithms for rapidly constructing bounding volume
hierarchies on manycore GPUs. The first uses a linear ordering derived from spatial Morton …

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

Though a large variety of efficiency structures for ray tracing exist, kd-trees today seem to
slowly become the method of choice. In particular, kd-trees built with cost estimation …

the present invention relates generally to methods and systems for image rendering in and
by digital computing systems, such as computer graphics methods and systems for motion …

With ray traversal performance reaching the point where real-time ray tracing becomes
practical, ray tracing research is now shifting away from faster traversal, and towards the …

Automatic activity recognition is an active research topic which aims to identify human
activities automatically. A significant challenge is to recognize new activities effectively. In …

We present a highly parallel, linearly scalable technique of kd‐tree construction for ray
tracing of dynamic geometry. We use conventional kd‐tree compatible with the high …

We present HLBVH and SAH-optimized HLBVH, two high performance BVH construction
algorithms targeting real-time ray tracing of dynamic geometry. HLBVH provides a novel …
