GPS 1.0
Gravitational Particle Simulator
--------------------------------

This is a little numerical analysis project. Basically
it uses a numerical method to simulate the behaviour
of some particles that follow the gravitational interaction
laws. The numerical method used to approximate the
differential equations is a 4th order Runge Kutta method.

The interface is very simple to use and so there is no on-line
help. 

You can drag the mouse in the 3D area holding down the first 
mouse button to move the viewpoint in the XY plane

You can drag the mouse in the 3D area holding the third 
mouse button to move the viewpoint in the ZY plane

If you hold the SHIFT key while dragging you will move
the lookat position instead of the viewpoint

Some examples are provided under the demos directory

I hope you will enjoy this toy.

Any comment or suggestion will be greatly appreciated.
