Hunyuan 3D-Part - A component-based 3D generative model launched by Tencent

What is Hunyuan 3D-Part?

Hunyuan 3D-Part is a 3D generative model developed by Tencent, composed of P3-SAM and X-Part. It achieves high-precision, controllable component-based 3D generation for the first time, supporting the automatic generation of 50+ components. Users can first generate the overall mesh using Hunyuan 3D 2.5 or 3.0, then P3-SAM automatically and accurately segments the components, and X-Part decomposes them into independent parts, outputting high-fidelity, structurally consistent part geometry while maintaining flexibility and controllability. It has wide applications in game modeling, 3D printing, and other fields, such as separating a car model into its body and wheels to facilitate game-based scrolling logic or step-by-step 3D printing. The models generated by Hunyuan 3D-Part are highly accurate, editable, and structurally sound, making them easier to edit, produce, and apply. It can be used free of charge through the Tencent Hunyuan 3D creation engine.

Main functions of Hunyuan 3D-Part

• Component-based 3D generationIt supports the automatic generation of 50+ components, which can decompose complex 3D models into independent parts, achieving high-precision and controllable component-based generation.
• Automatic component splittingThe P3-SAM model automatically and accurately performs semantic segmentation on 3D models, obtaining semantic features and bounding boxes of components.
• High-fidelity component outputThe X-Part model decomposes the overall mesh into independent parts, outputting high-fidelity, structurally consistent part geometry while maintaining flexibility and controllability.
• Multi-domain application supportIt is applicable to fields such as game modeling and 3D printing, such as optimizing component binding logic in games and step-by-step production in 3D printing.

The technical principle of Hunyuan 3D-Part

• Overall Mesh Generation: Using the Mixed 3D 2.5 or 3.0 model, generate a complete 3D model Mesh based on user input.
• Component splittingUsing the P3-SAM model, semantic segmentation is performed on the generated overall mesh, automatically identifying and extracting the semantic features and bounding boxes of each component to achieve accurate component segmentation.
• Component geometry generationThe X-Part model, based on the segmentation results, decomposes the overall mesh into independent part geometries, outputting high-fidelity, structurally consistent parts while maintaining the flexibility and controllability of the model.
