Yann Le Galltrying some fun relativistic warp effects
Steven Stadnicki (he/him)@ylegall This is joyous! Always love seeing the Penrose rotation. How did you render this? The first time I saw the effect it was in the longago (pre-WWW) using a ray tracer that'd been hand-modified for Lorenzian geometry.
@sstadnicki Thank you! The entire scene is a shader written in GLSL (via the openRNDR framework). It uses ray marching and signed distance fields.
