noise2

public float noise2(int iter,
 float x,
 float y,
 float det,
 float scale,
 float low,
 float high)

Parameters:

iter - number of iterations of scaled noise (same as "octaves")

x - x-coordinate

y - y-coordinate

det - amount of detail retained from each scaled iteration, aka "persistence"

scale - the effective distance between coordinate points, referred to as "inc" in our code

low - lower bound, typically for a pixel value

high - upper bound, typically for a pixel value

Returns:

the noise value at (x, y, z), the value of "noiz"

noise3

public float noise3(int iter,
 float x,
 float y,
 float z,
 float det,
 float scale,
 float low,
 float high)

Parameters:

iter - number of iterations of scaled noise (same as "octaves")

x - x-coordinate

y - y-coordinate

z - z-coordinate, incrementing z drives the animation over a 2D bitmap in x and y

det - amount of detail retained from each scaled iteration, aka "persistence"

scale - the effective distance between coordinate points, referred to as "inc" in our code

low - lower bound, typically for a pixel value

high - upper bound, typically for a pixel value

Returns:

the noise value at (x, y, z), the value of "noiz"
