What is 4D Raytracing? (Blackhole simulation) #SoME4

Blackhole and other spacetime simulations made in Python and GLSL. We'll delve into the basics of how relativity and spacetime are mathematically modeled, for the purposes of 4D ray-tracing. Thanks a lot for watching! Music: Fluidscape, Kevin MacLeod #blackhole #simulation #graphics #relativity
