PartDiffuser: New framework generates detailed 3D meshes via part-wise diffusion

Researchers have introduced PartDiffuser, a novel semi-autoregressive diffusion framework designed for generating detailed 3D meshes from point clouds. This method addresses limitations in existing autoregressive models by segmenting meshes into parts and employing autoregression between these parts for global topological consistency, while using a parallel discrete diffusion process within each part for high-fidelity geometric details. Based on the Diffusion Transformer (DiT) architecture, PartDiffuser incorporates a part-aware cross-attention mechanism and uses point clouds for hierarchical geometric conditioning, effectively separating global and local generation tasks. Experiments indicate that PartDiffuser surpasses current state-of-the-art models in generating detailed 3D meshes suitable for real-world applications. AI
