Black Hole

A black hole and its accretion disk, ray-traced in a shader. Light bends around it, so the far side of the disk shows above and below the hole. Drag to orbit, scroll or pinch to zoom.

Distances are in Schwarzschild radii. The disk starts at the innermost stable orbit, three of them out. Arrow keys orbit, plus and minus zoom. The picture drops resolution on its own when the GPU cannot keep up.
