Real-Time Ray Tracing Using Nvidia OptiX

Direct illumination and glossy effects are computed in the usual way, and diffuse effects are computed using the obscurances techniques.. The overall effect is a nice looking

We introduce several algorithms for leveraging the parallel processing power of consumer graphics hardware, ranging from the early NVIDIA GeForce 256 graphics cards to the

Conventional intersection testing in ray tracing is replaced by indexing a geometry field, such that real time inter- surface reflection is achieved on current graphics hardware..

While the core ray tracing algorithm might be embarrassingly parallel, scaling a ray tracer to render millions of pixels at real-time frame rates on a cluster remains challenging;

Improving BVH Ray Tracing Speed Using the AVX Instruction Set.

using real and complex light sources, defining a fast ray tracing algorithm to compute the reflector lighting and defining a new optimization algorithm to faster achieve the

In this paper we propose a very efficient pre-process to speed up the construction and traversal of sub-optimal, but fast-to-build hierarchies used for interactive ray tracing and

In the remainder of the paper, packet tracing refers to structure-of-arrays (SoA) based SIMD shading of small (e.g., 8-wide) packets with single-ray traversal, and stream tracing
