An object of configurable options.

equation
Function
An implicitly defined surface f(x,y,z) = 0 that body is constrained to e.g. function(x,y,z) { x*x + y*y + z*z - r*r } corresponds to a sphere of radius r pixels.
period
Number
The spring-like reaction when the constraint is violated.
dampingRatio
Number
The damping-like reaction when the constraint is violated.
Methods

applyConstraint(targets, source, dt)

Adds a surface impulse to a physics body.

Parameters
targets
Array.Body
Array of bodies to apply force to.
source
Body
Not applicable
dt
Number
Delta time
