| Abstract: |
| A new, easy and simple description to conic method in Computer-Aided Geometric Design was advanced thereby to unite all the expressions of the conic equations under the different conditions and restrictions. Thus, the sufficient and necessary conditions of unique existence of conic for the standard situation was obtained. The general equation and the parametric equation of the corresponding conic were deduced in this paper. |
