Abstract: A computer-implemented method for designing a three-dimensional (3D) mesh in a 3D scene. The method comprises displaying a 3D mesh in a 3D scene and providing a global orientation and selecting, with a pointing device, one or more vertices of the 3D mesh, thereby forming a set of one or more vertices. The method comprises computing at least one picking zone that surrounds each vertex of the set. The method comprises providing a first manipulator for controlling a displacement of each vertex of the set along one or more NUV directions and determining whether the pointing device is maintained within the picking zone. If not, the method comprises providing a second manipulator for controlling a displacement of the one or more vertices of the set along one or more directions defined by the global orientation. The method improves user interactions for switching back and forth a first and second manipulators.
