Hunyuan3D-2.1 is a generative 3D framework and image-to-3D pipeline that transforms single 2D images into textured 3D geometries. It functions as an asset generator that produces high-quality 3D meshes and textures using a flow-matching system.
The project includes a specialized synthesizer for creating photorealistic textures with physically based rendering properties. These tools allow for the simulation of metallic reflections and light interactions on generated models.
The system covers 3D asset pipeline automation through a sequence of shape generation and mesh refinement. It also provides utilities for fine-tuning pre-trained weights and training code to customize the generation process for specific applications.
