Conceitos essenciais
Sculpt3D integrates 3D shape and appearance information for multi-view consistent text-to-3D generation while maintaining high-quality generation capabilities.
Resumo
The content introduces Sculpt3D, a framework that enhances text-to-3D generation by incorporating 3D priors from reference objects. It addresses issues of inconsistent appearances and inaccurate shapes in 2D diffusion models. By utilizing sparse ray sampling and appearance modulation, Sculpt3D ensures multi-view consistency while preserving generative quality. Extensive experiments demonstrate significant improvements in fidelity, diversity, and multi-view consistency.
