摘要
绘制透视图涉及到视点、视角、视高、画面的远近及偏角等参数,有些参数需凭经验确定,因此在手工绘图时十分繁琐。在量点法作图的基础上,给出了一个手工绘制透视图的新量点法,作图时无需根据平面图确定画面和站点的位置和视角大小等,即可确定建筑物的主立面在整个透视图上的比重,方法简捷且便于控制。根据此原理设计了一个透视图尺,结构简单,使用方便,适合于手工绘图。
To draw perspective is related to many parameters, such as viewpoint, visual angle, visual height, distance of picture plane and declination angle, and so on. Some of these parameters must be defined by experience, so it is a hard job in the hand drawing. Based on the measuring point method for perspective drawing, a new measuring point method is presented which can define fine proportion of main elevation of construction in perspective drawing without relying on perspective point of drawing plane and visual angle, so this method is simple and easy to control. Then the perspective ruler is designed based on the principle of this method which is simple and suitable for hand drawing.
