“A 3D n-body gravity sandbox: glowing planets orbit in real 3D space; orbit the camera, fling new bodies, watch slingshots and merges.”
Real-time Newtonian n-body physics in WebGL — orbit and zoom the camera, drag-release to fling glowing planets that leave 3D trails, slingshot, and merge on collision in a starfield.
