Reconstructing space-time in 4D: 2D video turned into per-frame 3D gaussians
bilawalsidhu · x · 2026-09-23
Bilawal Sidhu demos a 'mad science' experiment: geolocated 2D video converted to per-frame 3D gaussians, each left precisely where and when it happened — effectively reconstructing space and time in 4D. He jokes it's how higher-dimensional beings might see us, invoking Vonnegut's 'great millipedes' line. More recipes and tools are promised via his Substack 'Map the World' (46k+ subscribers).
