Figure 1 : Edit example (left to right): The user places constraints (blue) and manipulates the object by moving constraints. Our deformation model maintains continuous and discrete patterns and adapts the repetition count of discrete patterns, inserting and deleting elements as needed to minimize distortion. Discrete changes are highlighted in orange. Abstract This paper introduces a new structure-aware shape deformation technique. The key idea is to detect continuous and discrete regular

We propose a variational deformation model that preserves these structures, and a discrete algorithm that adaptively inserts or removes repeated elements in regular patterns to minimize distortion. As a tool for such structural adaptation, we introduce sliding dockers, which represent repeatable elements that fit together seamlessly for arbitrary repetition counts. We demonstrate the presented approach on a number of complex 3D models from commercial shape libraries.
