random

float  random(float|intposition)

vector  random(float|intposition)

vector2  random(int position)

vector4  random(float|intposition)

Generate 1D, 2D, 3D, or 4D noise based on a 1D position.

float  random(float|intxpos, float|intypos)

vector  random(float|intxpos, float|intypos)

vector4  random(float|intxpos, float|intypos)

Specify a 2D position in the noise field using two numbers.

float  random(vector position)

vector  random(vector position)

vector4  random(vector position)

Specify a 3D position in the noise field using a vector.

float  random(vector4 position)

vector  random(vector4 position)

vector4  random(vector4 position)

Specify a 4D position in the noise field using a vector4.

Generate a random number based on the integer position in N dimensional space (where N is 1 to 4 dimensions). Unlike the noise functions, the random functions do not smoothly interpolate the random values between integer lattice points. The random() functions are very efficient ways of doing something like noise(floor(position)).

While random() takes floats, it only varies the random effect for integer changes. To have a random result that varies with even the smallest float changes, use rand().

The result of this is in the half-open interval [0, 1).
