This project evolved over round about two decades, one of them revisioned with svn and eventually git. But time went on, I made a lot of experiences, with Planeworld and with 3rdparty libraries, so head over to Planeworld Next Generation (PWNG)
planeworld is a 2D simulation engine and a passion project. The main goal of its development is best explained by the following examplary scenerio: Start a rocket from a plantery surface with simulated physics, such as rigid body dynamics, fuel system, planetary atmosphere, etc. Reach another celestial body, like a moon, using realistic trajectory planning, incorporating n-Body dynamics for the star system. Land on the target body and drive around with a rover, which is also simulated with springs and dampers, suspension, tire flex and more. The engine should allow for (Lua) scripting and remote missions with simulated communication and patchable onboard computers.
