| Abstract: | Using differential geometry as a tool,this paper deduces the contour line equation of stereoprojection for revolutionary curved face,the visible line equation and the equation of the sharp point on the visible line. The visibilities of the contour line and the sharp point on the visible line are also analyzed.And so supply the mathematical model for computer to draw rota- tion surfaces stereograph. |
