Abstract: In one embodiment, a three-dimensional (3-D) model is aligned with a view of a physical environment captured by a camera. An augmented reality view is generated by superposing elements of the 3-D model and the view of the physical environment. At least some of the elements of the 3-D model are initially hidden within the augmented reality view. A virtual window is imposed that penetrates a surface within the augmented reality view. The virtual window clips the view of the physical environment and elements of the 3-D model that intersect the virtual window to reveal initially-hidden elements of the 3-D model located beyond the virtual window. The augmented reality view with the virtual window is displayed on a display device.

Abstract: In one embodiment, an augmented reality application generates an augmented reality view that displays three-dimensional (3-D) ground penetrating radar (GPR) data on boundary surfaces of a virtual excavation. The augmented reality application calculates an intersection of the one or more boundary surfaces of the virtual excavation and the 3-D GPR data, and extracts data items of the 3-D GPR data that intersect the one or more boundary surfaces of the virtual excavation. The augmented reality application then projects two-dimensional (2-D) images based on the extracted data items onto the one or more boundary surfaces of the virtual excavation to show subsurface features in the augmented reality view that can be manipulated (e.g., moved, rotated, scaled, have its depth changed, etc) by a user.

Abstract: 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.

Abstract: 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.
