This paper presents an interactive morphing framework to empower users to conveniently and effectively control the whole morphing process. Although research on mesh morphing has reached a state where most computational problems have been solved in general, the novelty of our framework lies in the integration of global-level and local-level user control through the use of components, and the incorporation of deduction and assistance in user interaction. Given two polygonal meshes, users can choose to specify their requirements either at the global level over components or at the local level within components, whichever is more intuitive. Based on user specifications, the framework proposes several techniques to deduce implied correspondences and add assumed correspondences at both levels. The framework also supports multi-level interpolation control --- users can operate on a component as a whole or on its individual vertices to specify trajectories. On the whole, in the multi-level component-based framework, users can choose to specify any number of requirements at each level and the system can complete all other tasks to produce final morphs. Therefore, user control is greatly enhanced and even an amateur can use it to design morphing with ease.
