• Three-dimensional garment model
• Automatic alignment
• Penetration detection
• Mesh deformation

In recent years, researches on virtual fitting are mostly based on the data of garment pieces through Computer Aided Design. However, three-dimensional garment models are more intuitive, integrated and easy to access and manage. Therefore, we propose and design a method to automatically align virtual humans with three-dimensional garment models. Firstly, we basically align two models through three-dimensional geometric calculation and postural alteration of virtual humans. Then, we detect the penetration phenomena and define the points of the garment model penetrating into the human model as penetration points. Based on the penetration detection, we use Poisson mesh deformation to adjust the penetration points by imitating the adjustment process of dragging clothes. Finally, the results obtained from alignment can be directly used for physical-based simulation. Experimental results show that the method we propose can achieve good effects of alignment, and has good versatility and practicality.
