英文摘要： With the continuous proposed requirements on the aspects including quantity, quality, modeling efficiency in the application of computer entertainment, character animation, digital clothing customization, and Internet 3D model datasets, 3D garment modeling has been faced the significant challenges in terms of various garment shape styles and complicated data types. Thus, how to effectively edit and create large-scale and various 3D garments has become a hot research problem. The project will conduct research on the methods for 3D garment creation and editing by shape analysis and digital geometry processing. Based on the shape analysis and processing methods, the new technological approaches and theories for 3D garment modeling will be proposed. The major research issues are as follows: Firstly, we first develop the fine-grained description model for various characteristics of 3D garment style shape and fabric anisotropy which automatically to merge by the subspace clustering method. Secondly, we further propose a style and material-aware 3D garment editing method to solve the problems including style preservation, adaptive conformal transformation, and wrinkle details processing. Thirdly, we study and focus on the kernel function of connection relationship between clothing design components and garment structures. It can automatically generate a new garment model by learning the style design components parameters with the nuclear mapping optimization algorithm. Finally, the project will verify that the above method and algorithm theory. The research will help to solve the problems of significant growing of 3D garments in terms of quality and quality, and provide theoretical and technical support for the recent trend of the 3D garment numbers with the application in 3D network customization, virtual reality, and computer game and animation design.
