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.
The unified shader model uses the same hardware resources for both vertex and fragment processing. In the field of 3D computer graphics, the unified shader model (known in Direct3D 10 as "Shader Model 4.0") refers to a form of shader hardware in a graphical processing unit (GPU) where all of the shader stages in the rendering pipeline (geometry, vertex, pixel, etc.) have the same capabilities.
In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...
This shader works by replacing all light areas of the image with white, and all dark areas with a brightly colored texture. In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene—a process known as shading.
Direct3D 12 version 1703 – With the Windows 10 Creators Update (version 1703), released on April 11, 2017, the Direct3D 12 runtime has been updated to support Shader Model 6.0 and DXIL. and Shader Model 6.0 requires Windows 10 Anniversary Update (version 1607), WDDM 2.1. New graphical features are Depth Bounds Testing and Programmable MSAA.
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 ...
The shader assembly language in Direct3D 8 and 9 is the main programming language for vertex and pixel shaders in Shader Model 1.0/1.1, 2.0, and 3.0. It is a direct representation of the intermediate shader bytecode which is passed to the graphics driver for execution.
As the number of profile and shader types cropped up, Microsoft has switched to use the term "Shader Model" to group a set of profiles found in a generation of GPUs. [9] Cg supports some of the newer profiles up to Shader Model 5.0 as well as translation to glsl or hlsl.
