I=MM

这是错误的。

其实：设S为O系下O‘系的坐标，那么有：
O系下O‘系的描述=M*O’系下O‘系的描述，即：
S=M*I
S=M
所以M是O系下O‘系的坐标，即左边坐标系下，右边坐标系的坐标。

比如，O系下O'系的原点在（3，0，0）’处，那么有：
M=
1003
0100
0010
0001

假设O‘系中有一个点（3，0，0，1）‘，那么，O系中，它在：
M*P‘=（6，0，0，0）

上午正想准备，看到了，
收藏了！

模型变换是对坐标系的变换！

还有一个库GLUI也许可以满足你的要求:
/**
GLUI is a GLUT-based C++ user interface library which provides controls such as buttons, checkboxes, radio
buttons, spinners, and listboxes to OpenGL applications. It is window-system independent, relying on GLUT to
handle all system-dependent issues, such as window and mouse management.
**/
当然还有很多很优秀的GUI库.如smartwin++,wxWidgets等.每种都有其不同的设计特点.按需学习了~~~
