From the lecture I have learnt more about shadows. Appling Shadows is not the only method that can make the plane drawing looks like 3 dimensional. But compare to the transparent drawing it is less confuse and more impressive.
Apply shadow to objects in a space or whatever the environment, we could use different shadows and this will help to illustrate a clearly space relationship among each object. The picture above is a good example. Shadows as solids, therefore we can know the object’s shape accurate. Particularly, the different shades from light to dark enable us to understand which objects are near you or far from you. Same as the custom texture we are doing at the moment.
