These functions are similar to wnoise and vnoise. However, they are marginally less efficient in computation and don’t have the same characteristics. The bounds on the noise are roughly (-1, 1). Only 3D noise is supported. However, this noise has the ability to compute turbulence with roughness and attenuation on the noise.
