vector curlnoise2d(float x, float y)
vector curlnoise2d(vector xyt)
Computes a divergence free vector field based on the cross product of the derivatives of two Perlin noise functions.
The resulting vectors all lie along the X-Y plane.
Note
This is not the same as projecting a curlnoise
to a plane.
See noise and randomness in the VEX language guide for more information.
