stb_perlin_noise3

public static float stb_perlin_noise3(float x,
                                      float y,
                                      float z,
                                      int x_wrap,
                                      int y_wrap,
                                      int z_wrap)

Computes a random value at the coordinate (x,y,z).

Adjacent random values are continuous but the noise fluctuates its randomness with period 1, i.e. takes on wholly unrelated values at integer points. Specifically, this implements Ken Perlin's revised noise function from 2002.

The "wrap" parameters can be used to create wraparound noise that wraps at powers of two. The numbers MUST be powers of two. Specify 0 to mean "don't care". (The noise always wraps every 256 due details of the implementation, even if you ask for larger or no wrapping.)

Parameters:

x - the x coordinate

y - the y coordinate

z - the z coordinate

x_wrap - 0, or a power of two value that specifies the x wraparound coordinate

y_wrap - 0, or a power of two value that specifies the y wraparound coordinate

z_wrap - 0, or a power of two value that specifies the z wraparound coordinate
