ReGDiff: Guided Diffusion in Regulated Latent Space for Metamaterial Discovery

ReGDiff introduces a two-step method — RAS for latent space regulation and SRR for short-range repulsion during sampling — to generate geometrically valid, novel, and diverse metamaterial voxel structures, outperforming baselines on MetaTruss and MetaShell datasets with significant improvements in geometric rationality, novelty, and diversity.
