Alibaba Announces RichDreamer: A Generalizable Normal-Depth Diffusion Model for Detail Richness in Text-to-3D
In the context of text-to-3D, the key challenge lies in lifting 2D diffusion to 3D generation. The existing methods face difficulties in creating geometry due to the absence of a geometric prior and the intricate interplay of materials and lighting in natural images.
Practical Solutions and Value:
The proposed Normal-Depth diffusion model, RichDreamer, aims to provide a robust geometric foundation for high-fidelity text-to-3D geometry generation. It overcomes challenges by learning a joint distribution of normal and depth information, effectively describing scene geometry. The model showcases remarkable generalization abilities and is fine-tuned to learn diverse distributions of normal and depth in real-world scenes.
To address mixed illumination effects in generated materials, an albedo diffusion model is introduced to impose data-driven constraints on the albedo component, contributing to more accurate and detailed results.
The integration of the proposed Normal-Depth diffusion model into the Fantasia3D pipeline enhances geometric reconstructions and demonstrates superior performance in both geometry and textured model generation compared to state-of-the-art approaches.
The research team presents a pioneering approach to 3D generation, setting a new standard in the field. Future directions include extending the approach to text-to-scene generation and exploring additional aspects of appearance modeling.
