摘要
轴测投影的直观遵循形象思维的同一律,而要遵循同一律,又必须遵循相似原则、连续原则、接近原则(三原则),符合三原则的图形看上去位于同一平面。因此可根据三原则将轴测投影中空间元素的相对位置区分开来。投影面的垂直面可转化成投射线与平面的共面问题,当一个平面内有两条相交直线与另一平面具有连续相似接近的性质时,二平面才看上去共面。符合三原则的图形看上去还可组成一个整体图形,而人眼倾向于将一个图形知觉成结构特征数目最少的那种形式,即遵循简化原理,因此可根据三原则和简化原理减少图形空间特征数目,以利感知、记忆和理解。
Visualization of a axonometric projection conforms to the law of identity of imaginal thinking, If conforming to the law of identity, it have to conforms to the principle of similarity、continuity and proximity(three principles).The figures that conform to three principles look to be located to the same plane. There for, on the basis of the three principles .We can differentiate the relative location of space figure elements of axonometric projections .The perpendicular plane to a projection plane can be transformed into the coplanar problem of the projection and the plane. while there are continuity、similarity or proximity between any two intersecting lines of a plane and that of another plane, the two planes look to be coplanar. Figures that conform to three principles look to form a entirety figures, while eyes tend to perceive a figure to be the form that the number of structure characteristics are the least. That is , it conforms to the principle of simplification. So on the basis of the three principles and simplification, we can reduce the number of space structure characteristics, that is beneficial to perception、memory and comprehension.
