Abstract: A method for rendering a view from a lightfield includes identifying a ray associated with a portion of the view and selecting a set of camera views from a plurality of camera views representing the lightfield based on an intersection point of the ray with a plane. Each camera view has an associated contribution region disposed on the plane. The associated contribution region overlaps contribution regions associated with other camera views of the set of camera views at the intersection point. The method also includes determining a characteristic of the ray based on a contribution factor for each camera view of the set of camera views. The contribution factor is determined based on the relative position of the intersection point within the associated contribution region.

Abstract: Systems and methods are described for generating a virtual reality experience including generating a user interface with a plurality of regions on a display in a head-mounted display device. The head-mounted display device housing may include at least one pass-through camera device. The systems and methods can include obtaining image content from the at least one pass-through camera device and displaying a plurality of virtual objects in a first region of the plurality of regions in the user interface, the first region substantially filling a field of view of the display in the head-mounted display device. In response to detecting a change in a head position of a user operating the head-mounted display device, the methods and systems can initiate display of updated image content in a second region of the user interface.
