摘要
本文从考察计算机绘图的透视变换方法入手,分析论证了计算机绘图所用的透视变换的必要条件。通过实例验证,提出了对透视变换作出正误判断的方法。
The necessary condition of perspective transformations used in computer graphics has been analyzed and proved. By verifying some examples, a method of judging whether the perspective transformations are right or wrong has been advanced.
