Polyhedral Morphing Using Feature-Based Surface Decomposition

Features:

• Simple Intuitive User Interface: As shown above, the users only need to specify a few corresponding pairs of features on the two polyhedra. They can then specify the trajectories along which these features travel during the morph using Bezier curves, as shown below.

• Fine User Control: The algorithm not only provides the user with high-level control in terms of specifying the features and trajectories, it also allows for local refinement.
• Generality: The algorithm is applicable to all simple or genus zero polyhedra and makes no assumptions about convexity or star-shape. Furthermore, it can also be applied to non-simple homeomorphic polyhedra.
