使用Visual Studio 2005搭建opengl开发环境

使用Visual Studio 2005搭建opengl开发环境

1. 到http://www.xmission.com/~nate/glut.html 下载 glut-3.7.6-bin.zip，按如下方式安装解压出来的文件
glut32.dll ->C:\Windows\System or C:\WinNT\System
glut32.lib -> C:\ProgramFiles\Microsoft Visual Studio 8\VC\PlatformSDK\lib
glut.h -> C:\ProgramFiles\Microsoft Visual Studio 8\VC\PlatformSDK\include\gl
 
2. glut.h和stdlib.h一起使用会出现这个错误：error C2381: 'exit' :redefinition; __declspec(noreturn) differs
所以我们得修改glut.h，注释掉146行，并加入一条新的语句，改后的代码为：

Cpp代码  

1      // extern _CRTIMP void __cdecl exit(int); 

2      _CRTIMP
__declspec(noreturn) void __cdecl exit(int); 

 
3. 新建一个Win 32 Console Application工程，添加一个drawcircle.cpp文件，其内容为：

Cpp代码  

3      #include <stdio.h> 

4      #include <stdlib.h> 

5      #include <math.h> 

6      #include <GL/glut.h>

20     
21       if (d == 0) {  

22           printf("zero lengthvector");  

23           return;  

24       }  

25       v[0]/= d; v[1] /= d; v[2] /= d;  

26   }  

27     
28   void drawtriangle(float*v1,

41     
42       if (depth == 0) {  

43           glColor3f(v1[0]*v1[0], v1[1]*v1[1],v1[2]*v1[2]);

50           return;  

51       }  

52       v12[0] = v1[0]+v2[0];  

53       v12[1] = v1[1]+v2[1];  

54       v12[2] = v1[2]+v2[2];  

55       normalize(v12);  

56       subdivideCircle(radius,v1, v12, depth - 1);

76           depth = depth % 5;  

77       }  

78       circleRadius+=cnt;  

79       glClear(GL_COLOR_BUFFER_BIT);  

80       drawCircle(circleRadius);  

81       glutSwapBuffers();  

82   }   
83     
84   static

85   {

4. 工程 --> 右键 --> Properties，打开工程配置对话框，

a. 选择Configuration下拉框 ,选择 AllConfiguration



b. In the left pane, select the linker subtree and then click the Input
option. Add the following code to the
Additional Dependencies text in theright pane.
Copy and Paste: opengl32.lib  glu32.lib glut32.lib



5. 编译运行，如果成功，可以看到一个三维动画
