| Abstract: | The paper,in terms of the nature and principles of the axonometry projection,has given an explanation of how to set up a general axonometry coordinate system on the graphical screen of the computer.It describes the way of measure for the three-dimensional coordinate on the two-dimensional graphical screen and the reduction formula between the two coordinate systems.Meanwhile the author takes an example to show its simplicity when people draw the curved surface graph. |
