斜投影法在画法几何中的应用
The Application of Oblique Projection Method in Descriptive Geometry
-
摘要: 介绍了斜投影法的概念,通过改变投射线与投影面之间的夹角,可使光线从某一特定的角度照射空间物体,使其在投影面上的落影具有重影性,从而起到简化画法几何作图的目的.Abstract: This paper introduces the concepts of oblique projection method.The angle between projection line and projection plan changed and projection line lit the solid from special direction,so the shadow in projection plan overlap,the drawing has been simplified in descriptive geometry.
