Methods

• fragmentShaderLib
  Returns GLSL shader code for several useful functions for shaders, especially fragment shaders.

(static) module:extras/fragmentshaderlib.fragmentShaderLib()

Returns GLSL shader code for several useful functions for shaders, especially fragment shaders. TODO: Not documented fully yet. Contains the following functions:

• float rand(float seed): Generates a randomized hash of a number, in the interval [0, 1).
• float rand(vec2 seed): Generates a randomized hash of a two-number vector, in the interval [0, 1).
• float rand(vec3 seed): Generates a randomized hash of a three-number vector, in the interval [0, 1).
• float signedrand(float seed): Generates a randomized hash of a number, in the interval [-1, 1).
• float signedrand(vec2 seed): Generates a randomized hash of a two-number vector, in the interval [-1, 1).
• float signedrand(vec3 seed): Generates a randomized hash of a three-number vector, in the interval [-1, 1).

Return Value

The GLSL shader code. (Type: string)
