| 摘 要： | 给出了一种新的二维细分图形变形算法。该算法将曲线细分算法和2D图形的变形算法结合起来,并把2D图形的变形升级到3D空间内处理。通过计算并连接对应特征点,建立空间三角面片,从而可以直观地反映初末图形特征点之间的对应关系。通过判断3D三角面片是否相交,易于推断出变形中有无自交和萎缩现象。试验结果反映出该算法变形效果自然,是一种新的有效的2D图形的变形算法。

| Abstract: | A new algorithm for 2D shape morphing is presented,which is base on subdivision.The algorithm combined the curve subdivision method and 2D shape morphing method and solved the problem of 2D shape morphing in 3D space.The algorithm which established 3D triangular meshes through connecting the corresponding vertices could reflect the corresponding relations between the vertices clearly and could estimate the morphing sequence whether it produced bad effects through checking 3D meshes.The algorithm which can a... |
