Hunyuan3D-Omni - Tencent Mixed-Year Open Source 3D Model Generation Framework

What is Hunyuan3D-Omni?

Hunyuan3D-Omni (Hybrid 3D-Omni) is an open source 3D asset generation framework by Tencent Hybrid 3D team, which realizes accurate 3D model generation through multiple control signals. Based on Hunyuan3D 2.1 architecture, it introduces a unified control encoder that can handle multiple control signals such as point cloud, skeletal pose, bounding box, etc. to avoid signal confusion. The framework adopts a progressive, difficulty-aware sampling strategy for training, prioritizing the sampling of more difficult signals to improve the robustness of the model to missing inputs.Hunyuan3D-Omni supports multiple control modes, such as bounding box, skeletal pose, point cloud, voxel, etc., which can generate a character model with a specific pose, a model that conforms to the bounding box constraints, etc., and effectively solves the distortion of the traditional 3D generation, It effectively solves the problems of distortion and lack of details in traditional 3D generation. It has a broad application prospect in the fields of game, movie and television, design, etc., providing creators with more precise control ability and improving the accuracy and robustness of 3D asset generation.
