Abstract
Methods and systems are provided for a reprojection engine for augmented-reality devices. The augmented-reality device projects virtual content within a real-world environment. The augmented-reality device tracks a six degrees of freedom headpose of the augmented-reality device, depth information of the virtual content, motion vectors that correspond to movement of the virtual content, and a color buffer for a reprojection engine. The reprojection engine generates a reprojection of the virtual content defined by an extrapolation of a first frame using the headpose, the depth information, motion vectors, and the color surface data structure. The reprojected virtual content continues to appear as if positioned with the real-world environment regardless of changes in the headpose of the augmented-reality device or motion of the virtual content.
