Title: Variation-Range of Axonometric Co-ordinate System in Oblique Projection
Abstract: In the parallel projection, the distortions of the oblique ones to the orthogonal projection can be described by the angle made when projecting lines and image plane cross. This paper shows the variation-range of the axonometric co-ordinate system, consisting of the image unit and the angle of adjacent image axes, in the case of the oblique projection in which the angle made by the projecting line and the image plane is constant.
