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 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 ...
ARB vertex shader; ARB fragment shader; ARB shader objects; ARB geometry shader 4; ARB tessellation shader; ARB compute shader; GLSL shaders can also be used with Vulkan, and are a common way of using shaders in Vulkan. GLSL shaders are precompiled before use, or at runtime, into a binary bytecode format called SPIR-V, usually using offline ...

In August 2019, Nvidia announced Minecraft RTX, an official Nvidia-developed patch for the game Minecraft adding real-time DXR ray tracing exclusively to the Windows 10 version of the game. The whole game is, in Nvidia's words, "refit" with path tracing , which dramatically affects the way light, reflections, and shadows work inside the engine.
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.
Cg (short for C for Graphics) and High-Level Shader Language (HLSL) are two names given to a high-level shading language developed by Nvidia and Microsoft for programming shaders. Cg/HLSL is based on the C programming language and although they share the same core syntax, some features of C were modified and new data types were added to make Cg ...
The High-Level Shader Language [1] or High-Level Shading Language [2] (HLSL) is a proprietary shading language developed by Microsoft for the Direct3D 9 API to augment the shader assembly language, and went on to become the required shading language for the unified shader model of Direct3D 10 and higher.
