| Abstract: | This paper discribes the method of graphing space geometry by affine transformation. In the process of translation of graphic ring into graphic ellipse or graphic ellipse into graphic ring, it is the key to determine long and short axes, General method isn't easy to solve the problem accurately. Determining main direction by affine transformation, this paper discribing method, can accurately find out long and short axes.f |
