绘制透视图的视点内移法

A COMPOUND WAY FOR PERSPECTIVE

对透视基本理论进行了推导,创立了一种新的视点内移作图法。这种方法是将视点移到图纸幅面之内。不用灭点而直接在水平投影图上作图,不但所占板面很小,而且能准确地定出视点位置,从而可容易地估出视观效果。方法简单,作图迅速。

Generally speaking, most of the current method for perspective mean larger desk surfaces and are difficulty for precise estimation of visual effect. But now both of the defects motioned above can be completely overcome if one adopts the method advanced in this thesis.With a derivation on basic theory of perspective, this paper brings forword a new way-compound for perspective. This method moving the viewpoint into the frame of paper, neglecting the vanish point and directly drawing in the horzontle projective diagram.It only need a small dest surface and can locate the viewpoint accurately, thus the visual effect can be estimated precisely. Addtionally this method has the advantages of simplicity and time saving.
