Noise (vuo.noise)

Nodes for generating (pseudo)random numbers using various techniques.

Gradient noise (including Perlin noise and simplex noise) is useful for creating natural-looking movement and textures.

Uniformly distributed random numbers are useful for picking from a set of options. When a random number is generated from a uniform distribution, the number falls between a given minimum and maximum. Each number between the minimum and the maximum has an equal chance of being picked.

Many of these nodes can work with various types of numbers — Integers, Reals, 2D Points, 3D Points, 4D Points — because their ports have changeable data types. To change the type of number in the calculation, change the port’s data type. (For example, right-click on the port and select from the Set Data Type submenu.)
