Abstract: Embodiments of the present disclosure relate to continuous and/or binocular time warping methods to account for head movement of the user without having to re-render a displayed image. Continuous time warping allows for transformation of an image from a first perspective to a second perspective of the viewer without having to re-render the image from the second perspective. Binocular time warp refers to the late-frame time warp used in connection with a display device including a left display unit for the left eye and a right display unit for the right eye where the late-frame time warp is performed separately for the left display unit and the right display unit. Warped images are sent to the left and the right display units where photons are generated and emitted toward respective eyes of the viewer, thereby displaying an image on the left and the right display units at the same time.
