摘要
所有二次曲线皆为射影形,它们之间存在建立透射结构的可能性。本文从二次曲线问透射性质,分析了建立透射结构的条件,以及各种典型位置的透射结构形式,从而提出了对应曲线的作图。
Conic sections of different kind are projection graph, in which there are possibility to set perspective construction. According to the perspective character of conic sections, this paper analyses the condition setting perspective construction and the construction form of typical positions, Therefore, the homologous thread drawing is advanced.
