Projection Selection in Graphics Education
The purpose of this research is re-verification of the validity of projection selection in graphics education through understanding the historical development. In this paper we will especially pay attention to the difference between axonometric drawing and perspective drawing. For this purpose we examined several texts and typical drawings concerning to the selection of drawing method after Renaissance till the early 20<th> century. As a result, the following became clear. (1) Although a perspective depends to a viewpoint, we can draw the same figure if a viewpoint is defined, even if who draws. That is, a perspective expresses the spatial relationship between objects both objectively and quantitatively. (2) Axonometric drawing has different historical development process between orthogonal axonometric drawing and oblique axonometric drawing. (3) Oblique axonometric drawing has developed in the easy form of a simple perspective in early stage. Therefore, the oblique axonometric drawing needs to be understood to be near a perspective. (4) The theory of orthogonal axonometric drawing is established in the 19th century based on one of orthogonal projection followed to descriptive geometry. Therefore it needs to be understood as one sort of orthogonal projection opposed to oblique axonometry. (5) Many experts used unordinary selection of drawing especially in 20<th> century. We have to know und understand their reason and apply to graphic education.
