Black Hole Renderer

Semi-realistic Swarzchild black hole renderer using ray marching and the Schwarzschild metric.

Implemented in the Taichi programming language, which is embedded in Python.

Effects to-add:

• Bugfixes
  • The function orbital_velocity is in a different reference frame than coordinate_orbital_period

Effects added:

• Video rendering
• Motion blur
• CameraAnimation movement animation
• Black hole spinning over time
• Perlin noise to the accretion disk to provide texture and detail
• Ray tracing the accretion disk
• Gravitational redshift
• Relativistic doppler shift
• Gravitational lensing
• Blackbody radiation of accretion disk
• Volume rendering of accretion disk
• Relativistic beaming

A Note on CameraAnimation Animation

CameraAnimation animation works by importing camera settings from a .glb file. Only some .glb files are supported. To make sure your .glb file is supported, export with these Blender settings:
