摘要
本文简要回顾了《画法几何》投影理论体系中的内在矛盾,针对矛盾的焦点——三维形体投影的定义提出了自己的看法,特别是给出了三维形体的分析定义,并讨论了几个投影几何的基本定理。
This paper briefs the inner contradictions of the projection theory in the Descriptive Geometry, which focus lies in what this paper
explores and expounds--the definition of the projection for 3 - dimensional shapes, especially an analytic definition is given which is most valuable
for mathematical analysis.
