Class PhysicalMedium

java.lang.Object
  net.algart.model3d.common.movement.model.PhysicalMedium

All Implemented Interfaces:

Item

public final class PhysicalMedium
extends java.lang.Object
implements Item

Physical medium: an item which acts to any other item, which have a velocity, by PhysicalMediumResistanceRule interaction. It is supposed that the physical medium slows down the movement of any item, namely, acts to it with the resistance force F=−σvd, where d is some size of that item and σ is the parameter of this object: resistance coefficient.

This class is not thread-safe, but is thread-compatible and can be synchronized manually if multithread access is necessary.
