Abstract: An electronic device includes at least one sensor, a display, and a processor. The processor is configured to determine a dimension of a physical object along an axis based on a change in position of the electronic device when the electronic device is moved from a first end of the physical object along the axis to a second end of the physical object along the axis. A method includes capturing and displaying imagery of a physical object at an electronic device, and receiving user input identifying at least two points of the physical object in the displayed imagery. The method further includes determining, at the electronic device, at least one dimensional aspect of the physical object based on the at least two points of the physical object using a three-dimensional mapping of the physical object.

Abstract: In a system having a user-portable display device, a method includes maintaining a lightfield data structure representing at least a portion of a four-dimensional (4D) lightfield for a three-dimensional (3D) world in association with a first pose of the user-portable display device relative to the 3D world. The method further includes determining a second pose of the user-portable display device relative to the 3D world, the second pose comprising an updated pose of the user-portable display device. The method additionally includes generating a display frame from the lightfield data structure based on the second pose, the display frame representing a field of view of the 3D world from the second pose.
