Reference

Noise Noise is the bread and butter of ambient, and the package provides a long range of different noise functions, both for creating matrices and arrays of noise and for taking full control with the tidy interface.
noise_perlin() gen_perlin()	Perlin noise generator
noise_simplex() gen_simplex()	Simplex noise generator
noise_worley() gen_worley()	Worley (cell) noise generator
noise_cubic() gen_cubic()	Cubic noise generator
noise_value() gen_value()	Value noise generator
noise_white() gen_white()	White noise generator
noise_blue()	Blue noise generator
Patterns Pattern generators are useful for modifying noise values and get interesting effects, such as marble, and wood rings.
gen_spheres()	Generate a pattern of concentric spheres
gen_waves()	Generate a wave pattern
gen_checkerboard()	Generate a checkerboard pattern
Noise modifiers The raw noise values are not the end of it. ambient provides a range of functions to either modify the input, output or the generators themselves for new effects such as fractal noise.
fracture()	Create fractals of a noise or pattern
fbm()	Fractional Brownian Motion fractal
billow()	Billow (cloud-like, lumpy) fractal
ridged() spectral_gain()	Ridged-Multi fractal
clamped()	Clamped fractal
curl_noise()	Generate curl noise
gradient_noise()	Calculate the gradient of a scalar field
trans_affine() rotate() stretch() shear() translate() reflect()	Apply linear transformation to a long_grid
blend() normalise() normalize() cap()	Simply value modifications
Utilities While ambient is mostly about generating noise patterns it does come with a few utilities, wrapped around the long_grid class, which make it easy to work flexibly with the generated values
long_grid() grid_cell() as.array(<long_grid>) as.matrix(<long_grid>) as.raster(<long_grid>) slice_at()	Create a long format grid
