The common limitation of PP line drawing methods is when the object is zoomed-out, the line pixels dominates the outlook of characters. Our PP line drawing material has depth adaptation logic in it to handle this issue (Figure 6). This depth adaptation by default is on. If users want to turn it off to have the fixed width lines regardless of the depth of objects, they can do it by turning off the “Use Depth Adaptation” switch in the PP line drawing material instance (Figure 5).
