Ray tracing is a technique that can generate near photo-realistic computer images. A wide range of free software and commercial software is available for producing ...
OptiX is a high-level, or "to-the-algorithm" API, meaning that it is designed to encapsulate the entire algorithm of which ray tracing is a part, not just the ray tracing itself. This is meant to allow the OptiX engine to execute the larger algorithm with great flexibility without application-side changes.
Ray-traced model demonstrating specular reflection. Reflection in computer graphics is used to render reflective objects like mirrors and shiny surfaces.. Accurate reflections are commonly computed using ray tracing whereas approximate reflections can usually be computed faster by using simpler methods such as environment mapping.

This recursive ray tracing of reflective colored spheres on a white surface demonstrates the effects of shallow depth of field, "area" light sources, and diffuse interreflection. (c. 2008) In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images.

Ray-traced ambient occlusion is a computer graphics technique and ambient occlusion global illumination algorithm using ray-tracing. [1] [2] [3]
This meant that ray tracing a photo-realistic scene would take tens or hundreds of hours per frame. Algorithms such as Reyes which didn't generally ray trace run much faster with almost photo-realistic results. Speed: Rendering a two-hour movie at 24 frames per second in one year allows 3 minutes rendering time per frame, on average.
