1/6 A year and a half later, I finally finished my black hole project. #madewithunreal and now powered by #Niagara, this shader/sim implements physically correct gravitational lensing, which bends the light in all kinds of groovy ways! #gamedev #realtimevfx #astronomy #UE4 #UE5
2/6 A weird phenomena of gravitational lensing is the photon-sphere. @ScienceClic hooked me up with the equations I needed to represent this. When done correctly, zooming the camera in yields the same image repeat over and over to infinity (it gets small though)!
3/6 The accretion disk was my main focus this time around. I ended up learning how to write fluid solvers because I didn't want a static texture that was just warping around the event horizon. I wanted something alive, dynamic and violent.
