The two-hand interface and the resulting deformation are intuitive and hence offer an effective direct manipulation tool for creating or modifying 3D shapes. It is continuously applied to the shape, providing realtime graphic feedback. Using a new formalism based on a weighted average of screw displacements, Twister computes in realtime a smooth deformation, whose effect decays with distance from the grabbed points, simultaneously interpolating the 12 constraints. With a 6 DoF magnetic tracker in each hand, the user may grab two points on or near the surface of an object and simultaneously drag them to new locations while rotating the trackers to tilt, bend, or twist the shape near the displaced points. Furthermore, it solves for a space warp that simultaneously interpolates two sets of such displacement and orientation constraints. The Twister approach introduced here, adds the capability to impose an orientation change, adding three rotational constraints, at each displaced point.
