Abstract:

Virtual reality is provided by a mobile VR device. VR scenes are displayed by serving an application's image requests from a local cache of pre-rendered image frames. As the device user moves, image frames that match a VR scene viewed from a current pose (3D position and 3D orientation of the device translated to the virtual environment) are retrieved from the cache and displayed to the user as a VR scene. The cache may include a static cache including static image frames and a dynamic object cache including dynamic object image frames. The static cache may be indexed by the device current pose. The dynamic object cache may be indexed by the dynamic object's animation stage, orientation, and relative distance from the device user's current pose for a given time or movement-based trigger. Static image frames and dynamic object image frames may be composited, and displayed as a scene.
