摘要
本文建立了圆环斜二测投影的数学模型,并对投影中轮廓线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,为计算机辅助绘图提供了依据。
he mathematical model of ring′s cabinet drawing is developed. The visibility of its silhouette is analyzed and the formula to calculate the end points of the visible segment is derived. Hence, a proper basis for computer aided drafting is provided.
