Integrators

Integrators follow the Factory Pattern. Please read about the factory pattern to learn about creation, declaration, and extending integrators.

See also: API Reference on Integrators.

Integrators are fairly straightforward to create. Simply follow the Factory Pattern, and extend the methods .integrateVelocities() and .integratePositions().

Example:

Physics.integrator('my-integrator', function( parent ){

    return {
        
        integrateVelocities: function( bodies, dt ){

            // update the velocities of all bodies according to timestep dt
            // store previous velocities in .state.old.vel
            // and .state.old.angular.vel
        },

        integratePositions: function( bodies, dt ){

            // update the positions of all bodies according to timestep dt
            // store the previous positions in .state.old.pos
            // and .state.old.angular.pos
            // also set the accelerations to zero
        }
    };
});
