Permutation tables

{ perm : Array Int

, permMod12 : Array Int

}

Permutation table that is needed to generate the noise value.

permutationTableGenerator : Generator PermutationTable

Generate the permutation tables that are needed to calculate the noise value.

permutationTableFromInt : Int -> PermutationTable

Convenience function to generate a PermutationTable using an Int as a seed

noise2d : PermutationTable -> Float -> Float -> Float

Generates a noise value between -1 and 1 based on the given x and y value and a seeded permutation table.

noise3d : PermutationTable -> Float -> Float -> Float -> Float

Generates a noise value between -1 and 1 based on the given x, y and z value and a seeded permutation table.

noise4d : PermutationTable -> Float -> Float -> Float -> Float -> Float

Generates a noise value between -1 and 1 based on the given x, y, z and w value and a seeded permutation table.
