fbm1D
fbm1D(
x,options?):number
Defined in: src/modules/noise/noise.ts:517
Fractal Brownian motion, 1D: octaves of source summed at growing
frequency and shrinking amplitude, normalized by the summed absolute
amplitude so the result stays in [-1, 1] for any finite option combination
— including a negative gain, which yields a difference-of-octaves texture.
octaves is floored and capped at 32, and an overflow on any axis (runaway
gain / lacunarity / frequency, non-finite coordinate) yields 0 rather
than NaN.
This is the shape terrain, water and clouds actually sample.
