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.
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 ...
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.
Shader Model 2.0a — GeForce FX/PCX-optimized model, DirectX 9.0a. Shader Model 2.0b — Radeon X700-X850 shader model, DirectX 9.0b. Shader Model 3.0 — Radeon X1000 and GeForce 6, DirectX 9.0c. Shader Model 4.0 — Radeon HD 2000 and GeForce 8, DirectX 10. Shader Model 4.1 — Radeon HD 3000 and GeForce 200, DirectX 10.1. Shader Model 5.0 ...
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.
Shader Model 4.0 is a feature of DirectX 10, which has been released with Windows Vista. Shader Model 4.0 allows 128-bit HDR rendering, as opposed to 64-bit HDR in Shader Model 3.0 (although this is theoretically possible under Shader Model 3.0). Shader Model 5.0 is a feature of DirectX 11.
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.
UNIGINE rendered supported Shader model 5.0 with hardware tessellation, DirectCompute, and OpenCL. It also used screen space ambient occlusion and real-time global illumination. UNIGINE used a proprietary physics engine to process events such as collision detection, rigid body physics, and dynamical destruction of objects. It also used a ...
