GLSL shaders themselves are simply a set of strings that are passed to the hardware vendor's driver for compilation from within an application using the OpenGL API's entry points. Shaders can be created on the fly from within an application, or read-in as text files, but must be sent to the driver in the form of a string.
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.
Renderman Shading Language (abbreviated RSL) is a component of the RenderMan Interface Specification, and is used to define shaders.The language syntax is C-like.. A shader written in RSL can be used without changes on any RenderMan-compliant renderer, such as Pixar's PhotoRealistic RenderMan, DNA Research's 3Delight, Sitexgraphics' Air or an open source solution such as Pixie or Aqsis.

A procedural image made in Shadertoy with distance fields, modeled, shaded, lit and rendered in realtime. Shadertoy is an online community and platform for computer graphics professionals, academics [1] and enthusiasts who share, learn and experiment with rendering techniques and procedural art through GLSL code.
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.
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.
Mednafen (My Emulator Doesn't Need A Frickin' Excellent Name), formerly known as Nintencer, is an OpenGL and SDL multi-system free software wrapper that bundles various original and third-party emulation cores into a single package, and is driven by command-line input. [2] [3] It is distributed under the terms of the GPL-2.0-or-later license. [4]
