Multi-Layered Unseen Garments Draping Network

While recent AI-based draping networks have significantly advanced the ability to simulate the appearance of clothes worn by 3D human models, the handling of multi-layered garments remains a challenging task. This paper presents a model for draping multi-layered garments that are unseen during the training process. Our proposed framework consists of three stages: garment embedding, single-layered garment draping, and untangling. The model represents a garment independent to its topological structure by mapping it onto the $UV$ map of a human body model, allowing for the ability to handle previously unseen garments. In the single-layered garment draping phase, the model sequentially drapes all garments in each layer on the body without considering interactions between them. The untangling phase utilizes a GNN-based network to model the interaction between the garments of different layers, enabling the simulation of complex multi-layered clothing. The proposed model demonstrates strong performance on both unseen synthetic and real garment reconstruction data on a diverse range of human body shapes and poses.
