Stream3D Enables Streaming 3D Reconstruction and Generation Without Retraining

Stream3D, a collaborative effort from Harvard, MIT and HKUST, introduces a training‑free, memory‑efficient mechanism that continuously extracts reliable multi‑view evidence from video streams to drive frozen view‑conditioned 3D generators, achieving consistent, complete 3D reconstructions superior to both pure reconstruction and generation baselines.
