关于参数曲线的几何变换的一个注记

Note on geometric transformation of parameter curve

二维、三维图形的基本的几何变换可以通过齐次坐标在形式上统一起来,但是对于参数曲线的基本的几何变换,常用的教材并没有使用齐次坐标来加以统一处理,本文对参数曲线的基本的几何变换在什么条件下可以用齐次坐标在形式上进行统一处理加以讨论．

Fundamental geometric transformation of two and three-dimensional graphics may be unified in form through homogeneous coordinates. But to geometric transformation of parameter curve, the homogeneous coordinates didn＇ t be discussed in ordinary textbook. In this paper, the author will discuss the condition which makes the Fundamental geometric transformation of parameter curve be unified through homogeneous coordinates.
