摘要
运用代数法建立了圆环各类轴测投影图的通用数学模型，并对投影中轮廓线的可见性进行了分析，并导出了可见轮廓线端点坐标的计算公式。
This paper sets up a gerneral mathematical model of various armillary axonometric projection of a torus based on algebraic method. The visibility of its silhouetle is analyzed and formula to calculate the end points of the visible segment is derived. Hence, a proper basis for computer aided drafting is provided.
