openGL，glut庫安裝(vs2013)

最近要開始做三維重建，需要使用opencv 和 openGL,第一次使用OpenGL，當然要從裝glut庫來開始。

安裝步驟如下：

1.将glut.h，放在vs2013安裝目錄的include下，建立一個GL目錄（沒有的話）：例如我的路徑是： C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include\GL

2.将glut.lib和glut32.lib放在vs2013安裝目錄的lib下：例如我的路徑是：C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\lib

3.将glut.dll和glut32.dll放在系統的系統目錄下面：例如我的路徑是：C:\Windows\System32 和C:\Windows\SysWOW64（最好兩個都複制一遍）

這裡給出一個OpenGL的例子程式，用來驗證自己是不是搞定OpenGL了，如下（複制到建立的win32項目下即可）
