4.) Conclusions

Serveral visualization methods have been applied to the Lorenz system. The application of the 2-dimensional diagrams x(t) (section 3) give information of the long time behaviour of a complex dynamical system. Also visualizing trajectories in phase space (section 2 and 3 ) using proper ways of color-encoding is useful.
The 2-dimensional diagrams are more efficient for visualizing movements of many trajectories from or to fixed points over a long time.
The 3-dimensional visualization in phase space can give more detailed information that can not be provided by the 2-dimensional diagram as for instance visualizing a limit cycle (see section 3 for r=24.1).
On the other hand visualizing for instance 500 trajectories for r=6.0 (see section 3) in 3-D phase space would not give anything else than a dense mesh of curves.

The use of a physical model helps to interpret results given by computer graphics and allows to better unterstand the behaviour of a given complex system.
