Tridimensional visualization of the Verhulst dynamics -'Time Ships', a Tribute to Stephen Baxter- [Visualisation tridimensionnelle de la dynamique de Verhulst -'Les Vaisseaux du Temps', un hommage à Stephen Baxter-].

The Verhulst dynamics is defined using the following iteration:

                    X  = 0.5
                     0

                    X  = RX   (1 - X   )
                     n     n-1      n-1

Here, in this computation, the growing rate 'R' is no longer constant but changes its value periodically using the following arbitrary cycle:

R1 ==> R2 ==> R3 ==> R1 ==> R1 ==> R2 ==> R2 ==> R3 ==> R3 ==> R1 ==> R1 ==> R1 ==> R2 ==> R2 ==> R2 ==> R3 ==> R3 ==> R3 ==> R1 ==> R1 ==> R1 ==> R1 ==> R2 ==> R2 ==> R2 ==> R2 ==> R3 ==> R3 ==> R3 ==> R3

where {R1,R2,R3} are respectively the three coordinates of the current point inside the following domain [3.212,3.370]x[3.500,3.616]x[3.000,4.000]. Only the points corresponding to a dynamical system with a negative Lyapunov exponent are displayed.
