pAvoid [pAv]

The pAvoid tool is used to create a region or area within the image that affected particles will attempt to avoid entering and/or crossing.

It has two primary controls; one that determines the distance from the region a particle should be before it begins to move away from the region, and another to determine how strongly the particle moves away from the region.

A pAvoid tool creates a `desire' in a particle to move away from a specific region. If the velocity of the particle is stronger than the combined distance and strength of the pAvoid region, the particle's desire to Avoid the region will not overcome its momentum and the particle will cross that region anyway.
