This repository will contain the official implementation of the paper: PartCrafter: Structured 3D Mesh Generation via Compositional Latent Diffusion Transformers. PartCrafter is a structured 3D generative model that jointly generates multiple parts and objects from a single RGB image in one shot. Here is our Project Page.
