VGGRPO: 4D Latent Rewards for World‑Consistent Video Generation (ECCV 2026)

VGGRPO introduces a latent‑space geometry model and two 4D rewards—camera‑motion smoothness and geometry‑reprojection consistency—to eliminate drift and improve structural coherence in video diffusion models without altering their pretrained architecture, achieving state‑of‑the‑art results on static and dynamic benchmarks.
