Abstract: A system includes a head mounted display (HMD) device comprising at least one display and at least one sensor to provide pose information for the HMD device. The system further includes a sensor integrator module coupled to the at least one sensor, the sensor integrator module to determine a motion vector for the HMD device based on the pose information, and an application processor to render a first texture based on pose of the HMD device determined from the pose information. The system further includes a motion analysis module to determine a first velocity field having a pixel velocity for at least a subset of pixels of the first texture, and a compositor to render a second texture based on the first texture, the first velocity field and the motion vector for the HMD, and to provide the second texture to the display of the HMD device.

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.
