Visualization of a thin accretion disk around a Schwarzschild black hole

Simulate a thin accretion disk around a black hole on your Android device. The visualizations are based on Einstein's general theory of relativity for a Schwarzschild black hole. The apparent distortion of the disk is due to light rays that follow the curved spacetime.

Because of the heavy use of the GPU the visualization might be slow or even show nothing on older devices. That might be due to the insufficient precision of the graphics chip.

In contrast to the 'Gargantua' black hole from the movie 'Interstellar', the black hole has no proper spin, but it takes the lensing effect and the Doppler shift into account which let the left part of the disk appear much brighter than the rest.
