Document Summary
The following cube demonstrates the four different degrees of value for shading. Don"t waste time trying to create the perfect shading value. Remember that the direction of the light shading source determines the value of the shading on the surface of the object. Shading a curved surface is very much like shading a planar surface. The only difference is that the shading gradually changes from light to dark. Curved surfaces do not have a distinct edge to separate the value tones of the shading. As an artist, one has to gradually blend the white to gray and eventually black shading on a curved surface. This principle applies to all curved surfaces whether the object is a pipe, a cylinder, an apple, whatever! The surrealist belgian artist, ren magritte (1898-1967) questioned the boxconcept of modern architecture. The picture looks very strange, because, usually, houses cannot be "heaped up" like this.
