摘要
本文根据正轴侧投影原理，建立了三维矿图绘制的数学模型．并提出了解决三维图形隐藏线的消除及阴影线填充的处理方法。
In this paper based on the principle of orthogonal axonometric projection the mathematical model for three dimensional mine map plotting has been established and the methods used to handle the problems of eliminating the concealed lines and filling the shadow lines have also been presented.
