New Hierarchical Flow Matching method generates 3D point clouds

Researchers have introduced Hierarchical Flow Matching (HFM), a novel method for generating 3D point clouds. HFM addresses limitations in existing flow-based and diffusion models by employing a two-level approach that captures both global shape topology and local geometric details. This method decomposes generation into latent flow matching for overall shape and conditional point flow matching for detailed reconstruction, enabling efficient sampling with minimal Euler steps.
