摘要
鉴于绘制透视图的工作量大、作图复杂、若使用一种透视轴测尺进行绘制,则可使作图大大简化。本文首先应用画法几何方法,论证了透视坐标计算式,再进一步详细推导出透视轴测尺的计算式。
Seeing that the description of perspective drawing is very complex and waste most time, but the use of perspective axonometric scale permits to simplify the description of perspective drawing. This paper demonstrates perspective projection by use of the method of descriptive geometry at first, and calculating formula of perspetive coordinate, for reasons given, the calculating formula of perspective axonometric scale is derived in detail.
