Methods for generating and displaying images associated with one or more virtual objects within an augmented reality environment at a frame rate that is greater than a rendering frame rate are described. The rendering frame rate may correspond with the minimum time to render images associated with a pose of a head-mounted display device (HMD). In some embodiments, the HMD may determine a predicted pose associated with a future position and orientation of the HMD, generate a pre-rendered image based on the predicted pose, determine an updated pose associated with the HMD subsequent to generating the pre-rendered image, generate an updated image based on the updated pose and the pre-rendered image, and display the updated image on the HMD. The updated image may be generated via a homographic transformation and/or a pixel offset adjustment of the pre-rendered image.

Late stage reprojection

The subject disclosure is directed towards an object (e.g., an aspected vector, queue, map, stack and so forth) container having an exclusive interface, a shared-read-only interface and a shared-write (and read) interface to a common set of data. Use cases during runtime determine the appropriate interface to use. No locking is needed with methods of the exclusive interface or the read-only interface. The shared-write interface is configured to have only concurrency safe methods. Also described is blocking the use of other interfaces while one interface is in use, and the use of reference counter tracking to know when no concurrent readers and/or writers remain, to allow transitioning to use a different interface.
