轴测投影变换矩阵的研究

THE STUDY ON TRANSFORMATION MATRIXES OF AXONOMETRIC PROJECTION

在本文中,根据空间物体、投影方向、投影面和坐标系的关系,推导了包括正轴测投影和斜轴测投影的统一轴测投影变换阵。根据该变换矩阵可以导出各种轴测投影变换矩阵。根据物体的形状确定投影方向,并根据该变换矩阵可以获得物体的最清晰的轴测图。

In this paper,according to the relation between object,direction of projection,projec-tion plane and coordinate system,the general transformation matrix of projection which in-cludes orthogonal axonometric projection and oblique axonometric projection was deduced.According to this general matrix,other transformation matrices of axonometric projectionmay be obtained.According to the shape of any object,the direction of projection may bedetermined.Therefore,a clear axonometric projection drawing of objects can be obtained.
