Use mouse wheel to zoom animation (canvas is matched to the browser window).
α determines point brightness.
Dynamics of *N = 1 048 576* independent points is plotted.
Press *Stop* button to investigate strange attractor. For small force *F* or big
damping *δ* values you will get simple regular attractors.
GPU based simulation of the
Duffing oscillator.
Equations of the particle motion are

* x' = v,
*

v' = -δv - x - x^{3} + F sin(ωt).

The script uses the
4-th order
Runge-Kutta integration algorithm.
