    摘要: In one embodiment, a user's perception of three-dimensional (3-D) structure of points in a point cloud is enhanced by use of a flashlight virtual object. The flashlight virtual object has a field of view that includes an inner cone that encloses an inner zone and an outer cone that encloses an outer zone. A current position and orientation of the flashlight virtual object within the 3-D space of the point cloud is found. It is determined whether the any points of the point cloud fall within the inner cone of the flashlight virtual object, and, if so, the points of the point cloud that fall within the inner cone are highlighted. It is further determined whether any points of the point cloud fall within the outer cone of the flashlight virtual object, and, if so, the points of the point cloud that fall within the outer cone are highlighted.

    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.
