Shaders are simple programs that describe the traits of either a vertex or a pixel. Vertex shaders describe the attributes (position, texture coordinates, colors, etc.) of a vertex, while pixel shaders describe the traits (color, z-depth and alpha value) of a pixel. A vertex shader is called for each vertex in a primitive (possibly after ...
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 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.
[citation needed] In version 1.53, it added support for Cg shaders. [5] Version 1.55 added support for the MSU1 enhancement chip [6] found on the SD2SNES [7] The emulator PocketSNES for Pocket PCs is based on Snes9X. [8] There is also an unofficial Snes9x port compiled with Emscripten which runs inside a web browser. [9] [10]
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. HLSL is analogous to the GLSL shading ...
In 3D computer graphics, Phong shading, Phong interpolation,[ 1] or normal-vector interpolation shading[ 2] is an interpolation technique for surface shading invented by computer graphics pioneer Bui Tuong Phong. Phong shading interpolates surface normals across rasterized polygons and computes pixel colors based on the interpolated normals and ...
Video Shader is a graphics card feature that ATI advertises on their R300 and R400 cards. The R500 card is advertised as having Video Shader HD. Video shader is a feature that describes ATI's process of using Pixel Shaders to improve quality of video playback. It can also be used to perform post-processing, like adding a film grain, or adding ...
