Defines one or many relationships between sets of three particles. ```javascript var a = 0, b = 1, c = 2 var single = AngleConstraint.cre

Defines one or many relationships between an infinite axis and single particles. Orientaiton of the axis is defined by 2 points: `axisA` and `axi

Defines an infinite bounding plane which constrains all particles in the system. ```javascript var origin = [1.0, 2.0, 5.0] var normal =

Defines an axis-aligned bounding box which constrains all particles in the system to its bounds. ```javascript var min = [-10.0, -10.0, -

Base class for defining particle constraints. @class Constraint @constructor @param {Int} size Number of indices to be stored

Defines a directional force that affects all particles in the system. ```javascript var gravity = DirectionalForce.create([0.0, -0.1, 0.0])
