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.

Abstract: An HMD device identifies a pose of the device and identifies a subset of a plurality of camera viewpoints of a light-field based on the pose. The HMD device interpolates image data of the light-field based on the pose and the subset of the plurality of camera viewpoints to generate an interpolated view; and displays at the HMD device an image based on the interpolated view. By interpolating based on the subset of camera viewpoints, the HMD device can reduce processing overhead and improve the user experience.

Abstract: Systems and method relating to creating a virtual reality, such as a three-dimensional virtual reality, representation of physical scene. In this aspect, such a method may comprise gathering information from an array of cameras positioned on a two-dimensional planar surface. In this particular aspect, one or more of the cameras may be positioned at a different angle relative to the two-dimensional planar surface based at least in part on a respective distance of each of the one or more cameras from a midpoint of the planar surface. Furthermore, in this general aspect the method may further comprise processing the gathered information at least in part to render a virtual reality representation of the physical scene.
