Illusion of three dimensions As Gombrich said, "Art is illusion, and it is to create illusions", the world of artists is full of illusion. Especially, there is impossibility in the field of painting and graphic design because you must express a three-dimensional on a two-dimensional plane. An artist makes every effort to overcome this impossibility. Perspective (perspective drawing) is one of the most well-known methods. Other than that, various methods have been developed to express thickness and depth of shapes and relative positional relationship between the shapes. Perspective is truly the closest to our everyday sight experiences when solids and spaces are expressed using it. The method of perspective was enough when the description of landscapes and things similar to photographs are the main stream of paintings and designs. But, recently the way of the naturalism thinking remains just as a part in the whole world of arts. Only perspective can not respond to our needs to describe various expressions. Then what kind of methods are available to introduce
feelings of solid and space other than perspective? Let's consider this
in this section.
