PhysLDM: A Latent Diffusion Model for High-Fidelity Deformable Simulation

PhysLDM proposes a unified latent diffusion paradigm for one-shot high-fidelity deformable body simulation. At its core is a holistic spatiotemporal VAE that avoids the staircase artifacts of standard temporal compression, achieving approximately 2.48 mm reconstruction precision on meter-scale scenes with up to 78x token compression.
