Abstract
A mixed reality (MR) system is disclosed. The MR system may determine a first predicted head pose corresponding to a time that virtual reality imagery is rendered, determine a second predicted head pose corresponding to a selected point in time during a camera shutter period, and combine the virtual reality imagery with the stereoscopic imagery based on the first predicted head pose and the second predicted head pose. A simulator that employs remote (e.g., cloud) rendering is also disclosed. The simulator/client device may determine a first pose (e.g., vehicle pose and/or head pose), receive video imagery rendered by a remote server based on the first pose, and apply a timewarp correction to the video imagery based on a comparison of the first pose and a second pose.
