摘要:
In one embodiment, a flashlight virtual object is provided that has a field of view. Any portions of the representation that fall within the field of view of the flashlight virtual object are highlighted. The position and orientation of the flashlight virtual object is manipulated in three-dimensional (3-D) space using a pointing device that captures motion in two-dimensions, by translation of the flashlight virtual object about one or more of a plurality of user-selectable two-dimensional (2-D) planes, rotation of the flashlight virtual object about one or more of a plurality of user-selectable points, translation of the flashlight virtual object along, or parallel to, one or more of a plurality of user-selectable axis and/or automated movement to a nearest point.
