I'm putting together a game that will be played mostly with three dimensional gravity.
By that I mean multiple planets/stars/moons behaving realistically, and path plotting and path prediction in the gravity field.
Do you know of a physics engine that is capable of dealing with multiple bodies all attracted to one another?
I don't need scenegraph management, or rendering, just core physics. (collision detection would be a bonus, as would rigid body dynamics).
My background is in physics, so I would be able to write an engine that uses Verlet integration or RK4 (or even Euler integration, if I had to) but I'd much rather adapt an off the shelf solution.
