创建Mac 环境下的OpenGL工程

1.创建Mac程序: Xcode-> (File -> New ->Progect)  Cocoa APP -> 填写程序名,选择工程存储地址创建

001

2.删除文件 : AppDelegate.h,AppDelegate.m,ViewController.h,ViewController.m,main.m

再导入文件OpenGL 工程文件文件 “include”文件夹和“libGLTools.a”文件

002

3. 添加系统文件库“GLUT.framework”和“OpenGL.framework”库文件 “libGLTools.a”文件是(拖入工程时)系统默认导入的, 如果没有也要添加进去.

003

4.创建“main.cpp”文件:

GLShaderManager shaderManager;

voidChangeSize(intw,inth)

{

    glViewport(0,0, w, h);

}

voidSetupRC()

{

    glClearColor(0.0f,0.0f,1.0f,1.0f);

    shaderManager.InitializeStockShaders();

    GLfloatvVerts[] = {

        -0.5f,0.0f,0.0f,

        0.5f,0.0f,0.0f,

        0.0f,0.5f,0.0f,

    };

    triangleBatch.Begin(GL_TRIANGLES,3);

    triangleBatch.CopyVertexData3f(vVerts);

    triangleBatch.End();

}

voidRenderScene(void) {

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT);

    GLfloatvRed[] = {1.0f,0.0f,0.0f,1.0f};

    shaderManager.UseStockShader(GLT_SHADER_IDENTITY,vRed);

    triangleBatch.Draw();

    glutSwapBuffers();

}

intmain(intargc,char* argv[])

{

    gltSetWorkingDirectory(argv[0]);

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_RGBA|GLUT_DEPTH|GLUT_STENCIL);

    glutInitWindowSize(800,600);

    glutCreateWindow("Triangle");

    glutReshapeFunc(ChangeSize);

    glutDisplayFunc(RenderScene);

    GLenum err = glewInit();

    if(GLEW_OK!= err) {

        fprintf(stderr,"glew error:%s\n",glewGetErrorString(err));

        return1;

    }

    SetupRC();

    glutMainLoop();

    return 0;

}

5.运行工程: 会出现错误提示,将对应位置的的<> 系统引入, 根据提示全部更改为""直接引入就可以了, 只有错误提示的地方需要更改,其他地方引用照旧. 运行效果如下
