轴测投影中各夹角参数之间的关系

The Relationship between Each Intersection Angle Parameters in the Axonometric Projection

空间直角坐标系的三个轴互相垂直。把坐标系向轴测投影面投影时,坐标轴与轴测投影面的垂线的三个夹角,坐标轴与投影方向的三个夹角以及投影方向与轴测投影面的夹角,都直接影响到轴测投影的结果,因此讨论各个夹角之间的关系是必要的。本文讨论了相关七个夹角参数之间的关系。

The three axes of the coordinate system of right angle of the space are vertical. When doing the coordinate system the projection to the axonometric projection plane , the three intersection angles of the coordinate axes and the orthogonal line of the axonometric projection plane, the three intersection angles of the coordinate axes and the projection direction, and the intersection angle of the projection direction and the axonometric projection plane ,will all influence the results of the axonometric projection directly. So it is necessary to discuss the relationship between the each intersection angle. This article discusses the relation between the seven intersection angle parameters.
