what is openGL ?

OpenGL is a graphical library of standard used for the needs of graphical programming.

OpenGL is open-source. every language of programming have supported an openGL
and openGL can work in environment of windows, linux, unix, etc.

the basic library of openGL is GLUT. for the windows, the library consist of:
- glut.h
- glut32.lib
- glut32.dll

if you dont't put that library on your windows, the output or the grapich from your
program can't be presented. so, before that, we must put it on your windows.

how we do it...?

there are 3 step how to put that library on your windows :

1. copy file glut.h in folder c:\program file\
microsoft visual studio\vc98\include\GL
2. copy file glut32.lib in folder c:\program file\
microsoft visual studio\vc98\lib
3. copy file glut32.dll in folder c:\windows\system32


if you finish,
try to open your microsoft visual studio and make some graphical programming..... :)
