Apply a vector field to particles

Description

This force adjusts the velocity of particles based on a supplied vector field. The vector field can either be specified using x and y velocities, or angle and magnitude. Velocity adjustments are calculated based on a bilinear interpolation.

Training parameters

The following parameters defines the training of the force and can be passed along a call to wield()

• x : A matrix giving the velocity in the x direction at each grid point

• y : A matrix giving the velocity in the y direction at each grid point

• angle : A matrix giving the direction of the velocity at each grid point. Will only be considered if x and y are missing.

• vel : A single numeric or a matrix of the same dimensions as angle giving the magnitude of velocity at each grid point.

• xlim : The coordinate span of the vector field in the x direction.

• ylim : The coordinate span of the vector field in the y direction.
