3D Space Debris Cascade

This simulator renders low-Earth-orbit debris in full 3D: every object follows a true inclined orbital plane around a rendered Earth, and you can orbit the camera to see the shell from any angle. Because two orbital planes only ever cross along a single line through Earth's center, collisions cluster at those crossing nodes rather than spreading evenly — a geometric effect the flat 2D view can't show. Tune launch rate, fragmentation and inclination spread, and toggle active debris removal, to watch the shell either stabilize or spiral into a Kessler-syndrome cascade.
