New HLSL shaders, ray-generation, closest-hit, any hit, and miss, that are used describe computationally what DXR is doing when rendering raytracing. These shaders utilize the TraceRay function in HLSL to trace rays in the environment. When the ray interacts with the generated plane it can call on one of many selected hit or miss shaders.
Nvidia RTX (also known as Nvidia GeForce RTX under the GeForce brand) is a professional visual computing platform created by Nvidia, primarily used in workstations for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production, as well as being used in mainstream PCs for gaming.
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 these images. This article lists notable ray-tracing software.
A sample graph tree for Nvidia OptiX. In order to render a complex scene or trace different paths for any ray OptiX takes advantage of GPGPU computing by exploiting Nvidia CUDA platform. Since the process of shooting rays and setting their behavior is highly customizable, OptiX may be used in a variety of other applications aside from ray tracing.
Nvidia introduced their GeForce RTX and Quadro RTX GPUs September 2018, based on the Turing architecture that allows for hardware-accelerated ray tracing. The Nvidia hardware uses 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.
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 ...
Key elements include dedicated artificial intelligence processors ("Tensor cores") and dedicated ray tracing processors ("RT cores"). Turing leverages DXR, OptiX, and Vulkan for access to ray tracing. In February 2019, Nvidia released the GeForce 16 series GPUs, which utilizes the new Turing design but lacks the RT and Tensor cores.
