Pixel shaders range from simply always outputting the same color, to applying a lighting value, to doing bump mapping, shadows, specular highlights, translucency and other phenomena. They can alter the depth of the fragment (for Z-buffering), or output more than one color if multiple render targets are active. In 3D graphics, a pixel shader ...
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 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.
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.
The API was expanded with geometry shaders in OpenGL 3.2, tessellation shaders in OpenGL 4.0 and compute shaders in OpenGL 4.3. These OpenGL APIs are found in the extensions: ARB vertex shader; ARB fragment shader; ARB shader objects; ARB geometry shader 4; ARB tessellation shader; ARB compute shader
Pixel Shader 3.0, and Direct3D 10 or OpenGL 3 support [16] Modern Direct3D 11.1, OpenGL 4.4, or Vulkan GPU [8] Input device(s) Any PC input device – mouse and keyboard by default for Wii, mouse by default for GameCube: Original Nintendo GameCube controller with USB adapter [19]
Direct3D 11.0 features include: Support for Shader Model 5.0, Dynamic shader linking, addressable resources, additional resource types, [72] subroutines, geometry instancing, coverage as pixel shader input, programmable interpolation of inputs, new texture compression formats (1 new LDR format and 1 new HDR format), texture clamps to limit WDDM ...
The shaders support shader model 4.0 features. Architecturally, the GMA X3500 is very similar to the GMA X3000, [ 12 ] with both graphics cores running at 667 MHz . The major difference between them is that the GMA X3500 supports Shader Model 4.0 and DirectX 10 , whereas the earlier X3000 supports Shader Model 3.0 and DirectX 9 . [ 12 ]
