一种绘制透视图的"交汇法"

根据“交汇法”绘制轴测图的基本原理,把它推广、应用到绘制透视图,并从理论上结合用直观图示的方法给予了验证。特别是将这种方法与AutoCAD结合,既充分利用了已有的正投影图的图形资源,又充分发挥了AutoCAD的优越性,克服了传统绘图方法的缺点,使透视图的绘制变得轻松、快捷。通过对不同条件的分析及与传统方法的比较,更扩展了该法的适用范围。

A Method of Perspective Drawing by Einschneiderfahren

Based on the basic principle of axonometric projection by method of einschneiderfahren, this paper used it in perspective drawing. The method is testified intuitively. Especially combining with AutoCAD, the einschneiderfahren not only makes full use of the figure resource of orthography, but also gives play to the superiority of AutoCAD and conquers the disadvantages of traditional drawing method, facilitating the perspective drawing. By analyzing different conditions and comparing with the traditional method, it extends the useful scope of this method.
