> How could this scheme improve if we had access to the internals of the 3d scene? For example, could we adjust our sampling pattern based on depth information? If we had access to the internals, we could determine the visual salience of every object[1] and move the sampling pattern closer to the most salient one. Since that object is more likely to attract the viewer's attention, it would focus the rendering on those parts of the scene that the viewer actually cares about.
