| 摘 要： | 提出了一种用于服装设计的二维/三维映射算法.该算法基于弹簧质点变形模型,服装裁剪片二维到三维映射及三维到二维映射可以在该模型中得到统一的实现.在服装裁剪片二维到三维的映射过程中,二维裁剪片被放置在人体模型附近的初始位置,在缝合力的作用下,裁剪片自动变形并缝合到人体模型上.在服装裁剪片三维到二维映射的过程中,三维裁剪片被初始映射到指定的平面内,在弹性变形力的作用下,逐步变形并得到最终的二维裁剪片.在进行服装裁剪片二维到三维映射的过程中,考虑了干涉检验的问题.

| Abstract: | A 2D/3D transformation method used for computer aided garment design is presented in this paper. The method is based on spring-mass model. 2D to 3D and 3D to 2D transformations for cloth patterns can be implemented within the same model. In 2D to 3D transformation, 2D cloth patterns are located in their initial positions near the mannequin. Under the applying of sewing force, the cloth patterns are deformed and sewn together on the mannequin automatically. In 3D to 2D transformation, 3D cloth patterns are mapped on a given plane initially. Under the applying of elastic deformable forces, the initial mapped 2D cloth patterns will be deformed and the final shapes of the 2D cloth patterns can be obtained. In 2D/3D transformation for cloth patterns, collision detection is also considered. |
