摘要: 基于投影、坐标系和向量的基本概念和基本性质,可以十分简明地导出正轴测投影由4个约束方程构成的基本方程组。为确定6个轴测参数,应在合理选定2个参数后,从该方程组求出其他4个待定的参数,从而解决了正轴测投影的基本问题。对于选定2个参数的各种情况,文中都给出了求这些参数的解析解,并通过数值计算验证了这些解析解的正确性。

Abstract: Based on the basic concepts and characters of projections, coordinate systems and vectors, the set of fundamental equations formed by 4 constrained equations for orthogonal axonometric projection can be derived concisely. For 6 parameters of orthogonal axonometric projections, 2 parameters should be given firstly, and the other 4 parameters can be solved by the set of fundamental equations. For the all cases of giving 2 parameters, the solving equations of other parameters are derived correctly, and they are justified by numerical calculations.
