What is a Fragment Shader?
In Computer Graphics, the term "fragment shader" refers to the four-dimensional (4D) program that defines the appearance of an object, model or geometry.
A fragment shader is the part of a shader that defines the way that vertices are colored and create the final visual output of a geometry, model or object on a screen.
An example of a spot light shader.
Fragment shader programs are capable of taking in variables defined by software (i.e. uniforms) as well as taking in vertex specific data passed down from the vertex shader (i.e. varying or in/out).
