Details

The Hunyuan3D-2.1 project is structured around a modular pipeline for 3D shape and texture generation, driven by user input and managed through a flexible API. The process begins with user interaction via a Gradio UI or REST API, which feeds into an Input Processing & Data Loading component. This component prepares data for the core 3D Shape Generation Pipeline, which leverages advanced diffusion models to create initial 3D meshes. These meshes then undergo refinement and conversion in the Mesh Post-processing & Conversion component before being passed to the Texture Synthesis Pipeline for realistic PBR texture application, utilizing a Differentiable Rendering Engine. Finally, the processed 3D assets are delivered back to the User Interface & API Layer for visualization and export. A central Model & Configuration Management component provides essential configurations and model instances across all stages of the pipeline, ensuring consistent and controlled operations.
