Abstract
Examples are disclosed that relate to depth-aware late-stage reprojection. One example provides a computing system configured to receive and store image data, receive a depth map for the image data, processing the depth map to obtain a blurred depth map, and based upon motion data, determine a translation to be made to the image data. Further, for each pixel, the computing system is configured to translate an original ray extending from an original virtual camera location to an original frame buffer location to a reprojected ray extending from a translated camera location to a reprojected frame buffer location, determine a location at which the reprojected ray intersects the blurred depth map, and sample a color of a pixel for display based upon a color corresponding to the location at which the reprojected ray intersects the blurred depth map.
