4K4D

Real-time 4D view synthesis at 4K resolution (CVPR 2024) — the widely-cited seed (~1.8K★) of the zju3dv volumetric-video line from Xiaowei Zhou's group at the State Key Lab of CAD&CG. Successor FreeTimeGS (CVPR 2025) places free 4D Gaussian primitives at any time and place for real-time dynamic-scene reconstruction; siblings Street Gaussians and StreetCrafter carry the approach into driving-scene reconstruction.
