Nvidia OptiX (OptiX Application Acceleration Engine) is a ray tracing API that was first developed around 2009. [1] The computations are offloaded to the GPUs through either the low-level or the high-level API introduced with CUDA. CUDA is only available for Nvidia's graphics products. Nvidia OptiX is part of Nvidia GameWorks. OptiX is a high ...
Nvidia explains ray tracing in a video released Thursday, just in time for a new driver for GeForce GTX GPUs and new demos demonstrating the technology, according to a press release. The explainer ...
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.
In September 2018, Nvidia introduced their GeForce RTX and Quadro RTX GPUs, based on the Turing architecture, with hardware-accelerated ray tracing using a separate functional block, publicly called an "RT core". This unit is somewhat comparable to a texture unit in size, latency, and interface to the processor core.
The graphics card maker is readying itself to take on a $250 billion industry.
Instead of replacing rasterization entirely, however, the information gathered from ray-tracing can be used to augment the shading with information that is much more photo-realistic, especially in regards to off-camera action. Nvidia said the ray-tracing performance increased about 8 times over the previous consumer architecture, Pascal.
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 ...
It is a form of short-distance ray tracing done in a pixel shader. [ citation needed ] Relief mapping is highly comparable in both function and approach to another displacement texture mapping technique, Parallax occlusion mapping , considering that they both rely on ray tracing, though the two are not to be confused with each other, as ...
