Simulation of Schwarzschild black hole using OpenGL ray marching.
- Gravitational light deflection
- Gravitational redshift of accretion disk
- Doppler effect and relativistic beaming of accretion disk
- Realistic temperature distribution
- Accretion disk(Innermost stable circular orbit, orbiting speed)
Possible future updates:
- Doppler shift, redshift of background stars
- Observer position, velocity
- Orbiting star
- C++17 compiler
- cmake 3.25+
- OpenGL 4.3+ (for compute shader)
