DGGT: Feedforward 4D Reconstruction of Dynamic Driving Scenes using Unposed Images

CVPR 2026

Autonomous driving needs fast, scalable 4D reconstruction and re-simulation for training and evaluation, yet most methods for dynamic driving scenes still rely on per-scene optimization, known camera calibration, or short frame windows, making them slow and impractical. We revisit this problem from
