We present a gesture-based user interface to Free-Form Deformation (FFD). Traditional interfaces for FFD require the manipulation of individual points in a lattice of control vertices, a process which is both time-consuming and error-prone. In our system, the user can bend, twist, and stretch/squash the model as if it were a solid piece of clay without being unduly burdened by the mathematical details of FFD. We provide the user with a small but powerful set of gesture-based “ink stroke… CONTINUE READING
