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.
