This paper reviews the basic concepts of rays, ray tracing algorithms, and radio propagation
modeling using ray tracing methods. We focus on the fundamental concepts and the …

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 …

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 …

In this paper, we present Brook for GPUs, a system for general-purpose computation on
programmable graphics hardware. Brook extends C to include simple data-parallel …

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 most significant deficiency of most of today's interactive ray tracers is that they are
restricted to static walkthroughs. This restriction is due to the static nature of the acceleration …

Recursive ray tracing is a simple yet powerful and general approach for accurately
computing global light transport and rendering high quality images. While recent algorithmic …

Significant advances have been achieved for realtime ray tracing recently, but realtime
performance for complex scenes still requires large computational resources not yet …

We propose new approaches to ray tracing that greatly reduce the required number of
operations while strictly preserving the geometrical correctness of the solution. A …
