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).
This package makes up the BoxWrap2d library for Processing, a simple layer on top of JBox2d to ease construction, simulation, and display of physical worlds when using Processing.
