VCG - Random Field 2D

Description

Outputs random vectors, uniformly distributed on [-1,1]^2. Useful for sampling on a grid. Do not use directly as random field; discontinuous output. The state of the random number generator is shared across copies of this functor.

Details


The Random Field 2D model creates a field of random velocities uniformly distributed in $[-1,1]^2$ for the purpose of sampling. It is not directly usable as a random field, as the output is discontinous.
The sate of the random number generator is shared across copies of this functor.
