This is a simple two dimensional gravity simulator, consisting of several projects. More projects can be added using the same engine. The following simple test projects were used while configuring the physics and collision rules.
Once the physics was is place, I created more serious applications for it:
Solar System Liniar - The solar system, with all the planets starting off in a straight line
Solar System Randomised - The solar system, with planets starting of in randomised positions.
Coallese - 100 random spheres between 500 and 3000 km in diameter over a large area.
The content of this Wiki deals mostly with the solar system program.
