How VGGRPO Uses 4D Latent Rewards for World‑Consistent Video Generation

VGGRPO introduces a latent‑space geometry model and two 4D rewards—camera motion smoothness and geometry reprojection consistency—to improve geometric consistency in video diffusion models without sacrificing pre‑training generalization, achieving smoother camera paths and coherent scene structures even in dynamic scenarios.
