Abstract
We propose 3DFaceSculptor, a general-purpose framework for interactive 3D face editing. Given a source 3D face mesh with semantic materials, and a user-specified semantic image, 3DFaceSculptor can accurately edit the source mesh following the shape guidance of the semantic image, while preserving the source topology as rigid as possible. Recent studies on generating 3D faces focus on learning neural networks to predict 3D shapes, which requires high-cost 3D training datasets. These learning-based methods are limited in compatibility and can only handle face styles involved in the training datasets. Unlike these methods, our 3DFaceSculptor is a non-training and common framework, which only requires supervision from readily-available semantic images, and is compatible with producing various face styles unlimited by datasets. In 3DFaceSculptor, based on the differentiable renderer technique, we deform the source face mesh according to the correspondences between semantic images and mesh materials. However, guiding complex 3D shapes with a simple 2D image incurs extra challenges, that is, the deformation accuracy, surface smoothness, geometric rigidity, and global synchronization of the edited mesh must be guaranteed. To address these challenges, we propose a hierarchical optimization architecture to balance the global and local shape features, and further propose various strategies and losses to improve properties of accuracy, smoothness, rigidity, and so on. Extensive experiments show that our 3DFaceSculptor is able to produce impressive results and has reached the state-of-the-art level.
