My view is that Lean is several layers deep. The most visible layer is its set of practices.

我认为精益有几个层次。

Layer one on top of the other, and allow certain layers to be visible to certain types of devices.

将每个层放置在其他层的上面，并让某些层对于某些类型的设备是可见的。

The all-carbon formula doesn't need to be thickly spread to do its work, and it simply lets visible light through -- it could layer on top of a traditional solar cell to catch many more of the sun's rays.

ENGADGET: All-carbon solar cell draws power from near-infrared light, our energy future is literally that much brighter

So, this approach requires one more layer of effort: converting the height map (or at least its visible tiles) into a "normal map" which is smooth and natural enough to be subjected to lighting effects and then displayed on screen.
