摘要
本文建立了圆环斜二测投影的数学模型,并对投影中轮廓的可见性进行了分析,导出了可见轮廓线端点坐标的计算公式,同时还给出了用计算机绘制图形所需的框图。
The mathematical pattern of cabinet drawing of ring is set Up in this paper. The visibility of projection borderline curve is analysed, and the calculating formula of the end coordinates of visible borderline curve is also developed.Meanwhile, the necessary frame graph for computer drafting program are presented.
