| Abstract: | The matrix of projection, determined only by arbitrary centre and plane of projection from general conception of projection and three-dimensional projective coordinate, has been established. By means of general matrix of projection, var ious kinds of projection are summarized, and a method is presented to judge any kind of projection. As a result, a new algebraic method has been applied to the study of the theory of projection, and a new technique has been developed for the computer to draw figures of projection. |
