What is PartGen?

PartGen is an advanced 3D object generation and reconstruction framework, jointly developed by the Visual Geometry Group at Oxford University and Meta AI. PartGen can identify and generate 3D objects composed of meaningful parts, based on text prompts, images, or existing 3D models. PartGen automatically extracts and reconstructs individual parts of a 3D object using a multi-view diffusion model, while considering context to ensure proper fit between components. PartGen supports 3D part editing, allowing users to modify specific parts of a 3D object based on text instructions, improving the flexibility and control of 3D modeling.

PartGen's main functions

  • 3D object generation: Generate 3D objects composed of meaningful parts from text, images, or existing 3D objects.
  • 3D section editing: Users can edit specific parts of 3D objects based on text commands, increasing flexibility.
  • Automatic partial segmentation: Identify and segment different parts of a 3D object to provide a basis for subsequent operations.
  • 3D Reconstruction: After completing the partial segmentation, the 3D structure of each part is reconstructed.

PartGen's technical principles

  • Multi-view diffusion model: The multi-view diffusion model is used to process multiple views of a 3D object, and the model can identify reasonable partial segmentation.
  • Partial segmentation network: Train a network to process multi-view images and output a segmentation mask for each part.
  • Partially completed network: For occluded or invisible parts, use a multi-view diffusion model to complete the view of these parts.
  • 3D Reconstruction Network: The completed 2D view is input into the 3D reconstruction network to restore the 3D structure of each part.
  • Context integration: During the completion and reconstruction process, the model considers the contextual information of the entire object to ensure that all parts are integrated in a coordinated manner.
