Stretch ‘n’ cut: Method for observing and ungrouping complex virtual objects in 3D space using elastic band metaphor

We propose a system which realizes gesture-based separation, and the observation of a group of parts from complex virtual objects in 3D space. One practical application of our system is for training purposes such as learning the structures of complex 3D object such as the human body or industrial products. By using an “elastic band” metaphor, our method enables users to (1) observe the relationship (connection and its strength) between the parts and (2) separate a part of the object efficiently.
