10 iterations per frame

Drag mouse to rotate model. Hold shift key or use mouse wheel to zoom it (canvas is matched to the browser window). α determines point brightness. Dynamics of N = 4 194 304 independent points is plotted.
GPU based simulation of the Rossler strange attractor. Equations of the particle motion are
    x' = -(y + z),
    y' = x + ay,
    z' = b + (x - r)z.

The script uses the 4-th order Runge-Kutta integration algorithm. It makes 10 iterations per frame with time step dt.
