服装样片二、三维转换算法

服装样片二、三维之间进行转换的算法，使得服装样片二、三维转换得到统一实现。服装样片二维到三维和三维到二维的转换，满足转换前后，二维样片和三维样片的面积应近似相等，边界线相互对应且长度保持相等，关键点的位置应相互对应的条件。此过程应用Delaunay三角化技术、散乱数据插值技术，目的就是求出二、三维服装样片之间相互对应的中间点。最后利用可视化技术，给出了转换结果的直观效果，验证了该方法的可实施性。

Two-Dimension, Three-Dimension Transformation Algorithm of the Garment Pieces

In this paper, a two-dimension, three-dimension transformation algorithm used for the garment pieces is presented. The algorithm has realized the shift from two-dimension to three-dimension. The shift from two-dimension to three-dimension of the garment pieces contents their area, length of boundary lines and position of key points approximately equal. It applies the techniques of Delaunay triangular mesh generation, scattered data interpolation with the purpose of finding the corresponding medium point between the two and three dimension of garment piece. At last, we generate the visual effects of transformation result to the algorithm in application of visualization and meanwhile discussed it implementation.
