透视投影是为了获得接近真实三维物体的视觉效果而在二维的纸或者画布平面上绘图或者渲染的一种方法，它也称为透视图。透视投影的绘制必须根据已有的几何规则进行。

下面是一些基本的透视投影绘图规则的术语。

Perspective (from Latin:perspicere to see through) in the graphic arts is an approximate representation, on a flat surface (such as paper), of an image as it is seen by the eye. The two most characteristic features of perspective are that objects are smaller as their distance from the observer increases; and that they are subject to foreshortening, meaning that an object's dimensions along the line of sight are shorter than its dimensions across the line of sight.
