Abstract
A method for activating a virtual haptic geometry based on a position of a portion of an instrument relative to a target feature comprises detecting a presence of a reference point of an instrument within a threshold distance of a target feature. A virtual haptic geometry corresponding to the target feature is activated in response to the detected presence of the reference point of the instrument within the threshold distance.
