Abstract
Placement by one or more input mechanisms of a touch point on a multi-touch display device that is displaying a three-dimensional object is detected. A two-dimensional location of the touch point on the multi-touch display device is determined, and the touch point is matched with a three-dimensional contact point on a surface of the three-dimensional object that is projected for display onto the image plane of the camera at the two-dimensional location of the touch point. A change in applied pressure at the touch point is detected, and a target depth value for the contact point is determined based on the change in applied pressure. A solver is used to calculate a three-dimensional transformation of the three-dimensional object using an algorithm that reduces a difference between a depth value of the contact point after object transformation and the target depth value.
