ShaderLab is a declarative language for writing shaders used in the Unity3D game engine.

ShaderLab is a declarative language used in all shaders for Unity3D. By itself, ShaderLab can only be used to write simplistic fixed function shaders that are compatible with older devices. However, it is often used in conjunction with and inside of CGPROGRAM snippets to write more complex surface shaders or vertex and fragment shaders.
