6.15 DIRECTED FORCE

The DIRECTED FORCE method can be used for generating force fields with arbitrary and variable directions. Thus, it can be used for simulating wind, turbulence etc.

The DIRECTED FORCE requires only one parameter, which describes the direction of the force field during the animation. When the animation is played, the method evaluates a point and a corresponding direction from the parameter curve. The distance between the evaluated point and the particles is used for determining the strength for the force. Thus, the closer the particle is the parameter object, the stronger the force.
