1. A method comprising: generating, via a ray tracing algorithm, color values for a first subset of pixels of a display device allocated to a first viewpoint, the color values for the first subset of pixels based on a representation of a scene as seen from the first viewpoint; generating, via the ray tracing algorithm, color values for a second subset of the pixels of the display device allocated to a second viewpoint, the color values for the second subset of pixels based on a representation of the scene as seen from the second viewpoint, wherein the first and second subset of pixels of the display device comprise mutually exclusive pixels of the display device; and forming a composite image of the scene based on the color values generated for the first and second subset of pixels of the display device.
