摘　　要：根据透视学的基本原理,充分利用视线交点法(工程师法)和量点法的优点,设计了一种全新的透视画法。该法无需根据平面图先确定画面和站点等的位置及视角的大小,而是根据透视投影的空间几何关系,建立相应的数学模型。以反向思维的方法,在一系列参数中,依自己的意愿确定几个关键的参数,即可画出表达效果理想的透视图。本方法作图十分方便,尤其在CAD中作图,更能显示其优越性。Based on the basic principle of perspective drawing, a new method for prospective drawing has been developed in this paper with full use of the advantages from method of sight line intersection (engineer method) and measuring point method. By this method the math model is based on spatial relation of perspective projection without relying on the perspective point of drawing plane and visual angle. With reverse thinking, an ideal perspective drawing could be obtained by confirming some key parameters among a series of parameters. This method is convenient for drawing, especially in CAD.
