可控制形状的多边形变形算法

2D polygon morphing based on polygonal shape controlling

提出了一种可控制形状的多边形变形算法。该方法在源和目标多边形上指定对应的特征点,通过特征点的位置变化来带动整个多边形变化。得到的中间多边形在特征点约束下保持原内在量相对关系的最小变化,有效去除了多余的形变。通过试验表明,该算法产生的变形序列能很好地避免萎缩、自交等不自然现象,取得了良好的变形效果。

This paper presents an approach to 2D polygon morphing based on polygonal shape controlling.The method speci-fies feature points in the source and target polygont,hen the changes of the position of the feature points bring the entire polygon changes.Under the constraint of the feature pointst,he result middle polygon gets a smallest change.Experimental re-sults show that the morphing sequence produced by the solution can avoid the shrinkage commendably and achieve better morphing effects.
