| 摘 要： | 目前,在一些计算机图学的书籍中,根据其透视变换矩阵所绘的图形异常,不符合透视投影原理,不能满足工程上的需要。为此,(1)推导了符合透视投影理论的3种透视的变换矩阵。(2)分析了3种透视变换矩阵参数的合理数量。(3)分析了矩阵参数的意义、对图形的影响、并提出合理选取范围。(4)为了用计算机绘出符合工程上需要的图样,提出了有关的方程和确定参数的顺序。

| Abstract: | In this paper, we have studied the following four problems.1. The transformation matrix of perspective accord with theory of perspective has been proved.2. Analysed the number of parameters of the transformation matrix of perspective projection.3. Analysed the meanings of parameters of the transformation matrix and gave the methods of selection of parameters of the transformation matrix.4. Gave two equations for perspective drawing according to engineering. |
