What is a Vector Field?

A vector field is a uniform grid of vectors that influence and control the directional velocity of a particle.

Below you'll see the vector field represented by a bounding box in a brownish color and an array of arrows. Each one of these arrows represents the direction and intensity of a vector. These vectors influence the motion of the particles.

In this case, the center vectors are forming a clockwise rotation while the other vectors form a counterclockwise rotation.
