The Three-Body Problem

Try to find a stable orbit!

How to  pause, zoom, edit, and reset the simulation:

Press space to start/stop simulation.  Press R to reset  to the last paused state.

While paused, click on a body to move it, shift-click  a body to change its velocity, press backspace to clear all velocities. 

Press 1-4 to follow a specific object with the camera.  Press escape to follow the center point of the objects.

Press tab to toggle manual zoom mode. In manual zoom mode press O to zoom in and L to zoom out. 

Dev Note:

This uses basic Euler integration to calculate the net force on each body. I want to use a better method such as Verlet, leapfrog, or a fourth-order Runge-Kutta. 

I also want to handle collisions or at least dampen the forces when a mass gets too close to another.

The smallest body has negligible mass to approximate the orbit of a planet so this still fits into the three-body problem.
