PartCrafter is a pioneering open source project focused onGenerate editable multi-part 3D models from a single RGB image. Its core innovations are reflected in three areas:
- Structured generation techniques: Breaking away from the traditional holistic modeling approach and using combined latent space to represent each 3D part independently (e.g., backrest, seat, legs of a chair, etc.)
- Hierarchical Attention Mechanisms: Simultaneous global consistency (stylistic uniformity) and local detail accuracy between parts through a pre-trained 3D mesh diffusion transformer (DiT)
- Large-scale data support: Based on a training set of 130,000 3D objects (100,000 of which contain multi-part annotations), it is possible to hypothesize the rational structure of the invisible parts of a picture
Compared to traditional tools that can only generate a single overall model, PartCrafter's output can be directly imported into Blender and other software forPart level editing(e.g., adjusting chair leg lengths individually), which can be valuable in areas such as game asset creation and product prototyping.
