The model utilizes a novel training approach that "unlocks the potential of the diffusion prior".

Researchers Junzhe Zhu and Peiye Zhuang have introduced HiFA, a novel high-fidelity text-to-3D method with advanced diffusion guidance. The method utilizes the diffusion prior and a novel training approach to maximize the potential of the diffusion prior, enabling advanced photorealism and improved multi-view consistency. Additionally, the method applies auxiliary depth supervision for NeRF-rendered images and regularizes the density field of NeRFs, enhancing 3D geometry representation.

And here are some 3D meshes the team generated using the proposed method:
