NS-Diff: Adding a Physics Engine to Diffusion Models for Fluid and Rigid‑Body Dynamics

The CVPR 2026 paper introduces NS‑Diff, a physics‑guided video diffusion framework that combines a noise‑robust dynamics detector, a physical‑condition latent injection module, and reinforcement‑learning optimization to reduce jerk error by 43 % and fluid divergence by 33 %, achieving superior physical realism and visual quality across multiple benchmarks.
