In this project, we propose a novel 3D morphing technique that avoids creating a merged embedding that contains the faces, edges and vertices of two given embeddings. This novel 3D morphing technique dynamically adds or removes vertices to gradually transform the connectivity of 3D polyhedrons from a source model into a target model and simultaneously creates the intermediate shapes.

中文摘要在本专题研究计画中，我们提出一项新的三维物体变形技术，此变形技术所能处理的资料型态为two-manifold 之三维网格物体，此技术不需产生一个共有的高复杂度的网格物体或对原始物体进行重新网格化以产生相同连接关系，取而代之的是直接进行来源与目的物体之间几何与连接结构之转换，我们称此项新技术称为渐进式连接结构之转换(progressive connectivity transformation)，此技术藉由动态增加或移除顶点的方式从来源物体到目的物体逐渐地进行连接结构转换同时使用线性位置内差来产生一序列中间物体。
