Generates a Simplex or Perlin noise value in 1-4 dimensions.
Simplex noise is closely related to Perlin noise. It is widely used for procedural content generation.
There are many webpages which discuss Perlin and Simplex noise in detail.
Contents
Function
Generates Simplex noise from 1 dimension.
Synopsis
value = love.math.noise( x )
Arguments
number x- The number used to generate the noise value.
Returns
number value- The noise value in the range of [0, 1].
Function
Generates Simplex noise from 2 dimensions.
Synopsis
value = love.math.noise( x, y )
Arguments
number x- The first value of the 2-dimensional vector used to generate the noise value.
number y- The second value of the 2-dimensional vector used to generate the noise value.
Returns
number value- The noise value in the range of [0, 1].
Function
Generates Perlin noise (Simplex noise in version 0.9.2 and older) from 3 dimensions.
Synopsis
value = love.math.noise( x, y, z )
Arguments
number x- The first value of the 3-dimensional vector used to generate the noise value.
number y- The second value of the 3-dimensional vector used to generate the noise value.
number z- The third value of the 3-dimensional vector used to generate the noise value.
Returns
number value- The noise value in the range of [0, 1].
Function
Generates Perlin noise (Simplex noise in version 0.9.2 and older) from 4 dimensions.
Synopsis
value = love.math.noise( x, y, z, w )
Arguments
number x- The first value of the 4-dimensional vector used to generate the noise value.
number y- The second value of the 4-dimensional vector used to generate the noise value.
number z- The third value of the 4-dimensional vector used to generate the noise value.
number w- The fourth value of the 4-dimensional vector used to generate the noise value.
Returns
number value- The noise value in the range of [0, 1].
