stb_perlin_fbm_noise3	back to summary
public static native float stb_perlin_fbm_noise3(float x, float y, float z, float lacunarity, float gain, int octaves) Computes Fractal Brownian Motion noise. Calls `perlin_noise3` `octaves` times, so this parameter will affect runtime. Parameters x:float the x coordinate y:float the y coordinate z:float the z coordinate lacunarity:float spacing between successive octaves (use exactly 2.0 for wrapping output) gain:float relative weighting applied to each successive octave octaves:int number of "octaves" of `noise3()` to sum

public static native float stb_perlin_fbm_noise3(float x, float y, float z, float lacunarity, float gain, int octaves)

Computes Fractal Brownian Motion noise. Calls perlin_noise3 octaves times, so this parameter will affect runtime.

Parameters

x:float: the x coordinate
y:float: the y coordinate
z:float: the z coordinate
lacunarity:float: spacing between successive octaves (use exactly 2.0 for wrapping output)
gain:float: relative weighting applied to each successive octave
octaves:int: number of "octaves" of noise3() to sum

stb_perlin_noise3	back to summary
public static native 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:float the x coordinate y:float the y coordinate z:float the z coordinate x_wrap:int 0, or a power of two value that specifies the x wraparound coordinate y_wrap:int 0, or a power of two value that specifies the y wraparound coordinate z_wrap:int 0, or a power of two value that specifies the z wraparound coordinate
