摘要:

我们提出 FashionEngine,这是一个交互式 3D 人体生成与编辑系统,可通过自然语言、视觉感知和手绘草图等用户友好的多模态控制创建 3D 数字人。FashionEngine 通过三个关键组件实现 3D 人体制作自动化:1)预训练 3D 人体扩散模型,从 2D 图像训练数据中学习在语义 UV 潜空间中对 3D 人体建模,为多样化生成和编辑任务提供强先验。2)Multimodality-UV Space 在规范的 UV 对齐空间中编码人体服装的纹理外观、形状拓扑和文本语义,将用户多模态输入与隐式 UV 潜空间忠实地对齐,以实现可控的 3D 人体编辑。该多模态-UV 空间在文本、图像和草图等不同用户输入之间共享,从而支持各种联合多模态编辑任务。3)Multimodality-UV Aligned Sampler 学习从扩散先验中采样高质量且多样化的 3D 人体。大量实验验证了 FashionEngine 在条件生成/编辑任务上的最先进性能。此外,我们为 FashionEngine 提供了交互式用户界面,在统一框架中支持条件与无条件生成任务,以及姿势/视角/形状控制、文本、图像和草图驱动的 3D 人体编辑和 3D 虚拟试穿等编辑任务。项目页面位于:https://taohuumd.github.io/projects/FashionEngine。

英文摘要:

We present FashionEngine, an interactive 3D human generation and editing system that creates 3D digital humans via user-friendly multimodal controls such as natural languages, visual perceptions, and hand-drawing sketches. FashionEngine automates the 3D human production with three key components: 1) A pre-trained 3D human diffusion model that learns to model 3D humans in a semantic UV latent space from 2D image training data, which provides strong priors for diverse generation and editing tasks. 2) Multimodality-UV Space encoding the texture appearance, shape topology, and textual semantics of human clothing in a canonical UV-aligned space, which faithfully aligns the user multimodal inputs with the implicit UV latent space for controllable 3D human editing. The multimodality-UV space is shared across different user inputs, such as texts, images, and sketches, which enables various joint multimodal editing tasks. 3) Multimodality-UV Aligned Sampler learns to sample high-quality and diverse 3D humans from the diffusion prior. Extensive experiments validate FashionEngine's state-of-the-art performance for conditional generation/editing tasks. In addition, we present an interactive user interface for our FashionEngine that enables both conditional and unconditional generation tasks, and editing tasks including pose/view/shape control, text-, image-, and sketch-driven 3D human editing and 3D virtual try-on, in a unified framework.
