Abstract
The technology described herein is directed to a Bezier manipulation tool that facilitates a handle-movement paradigm for cohesive manipulation of a selected group of Bezier handles. In some implementations, the Bezier manipulation tool manipulates a selected group of Bezier handles by collectively selecting and synchronously (or concurrently) manipulating multiple handles. For example, when the Bezier manipulation tool detects a user-initiated manipulation of a reference handle of a selected group of Bezier handles, angular and radial length movements of the reference handle occurring as a result of the user-initiated manipulation are calculated relative to an anchor point associated with the reference handle. The Bezier manipulation tool cohesively manipulates other Bezier handles of the selected group of Bezier handles in accordance with the angular and radial length movements of the reference handle, e.g. {delta-theta, delta-r}, concurrent with the user-initiated manipulation of the reference handle.
