Packages
org.jbox2d.collision This package contains the broad and narrow phase collision algorithms.
org.jbox2d.common This package contains various math and utility functions used by all of JBox2d, including vectors (Vec2), matrices (Mat22), transforms (XForm), colors (Color3f), and CCD sweeps (Sweep), as well as the global settings for the simulation (Settings).
org.jbox2d.dynamics This package handles non-collision aspects of simulation.
org.jbox2d.dynamics.contacts This package performs contact handling, and is essentially internal to JBox2d.
org.jbox2d.dynamics.joints This package deals with all things joint-related.
org.jbox2d.testbed The JBox2d 2.0 testbed, implemented using Processing.
org.jbox2d.testbed.tests This package containst all the testbed examples, which extend org.jbox2d.testbed.AbstractExample.
