摘要
坐标的使用是OpenGL开发的重要基础，而OpenGL中的坐标系统种类较多，使用起来也更为复杂，因此本文阐述分析了OpenGL中各种坐标系统的区别和联系、坐标系统相互之间转换的实质以及坐标单位的确定等坐标使用的常见问题对深入理解OpenGL坐标使用具有一定的指导意义。
The use of coordinate is importance to development in OpenGL.Because OpenGL has plenty varieties of systems of coordinate, it＇s application more complex and difficult.The text made an exposition of difference and relational about different systems of coordinate, and it analyze the substance of translation in different systems of OpenGL＇s coordinate and unit of these coordinate.It is of instructional meaning to understand the use of coordinate in OpenGL.
