Mac OSX下搭建OpenGL超级宝典5（蓝宝书）开发环境（运行第一个三角形程序）

1.下载OpenGL超级宝典5（蓝宝书）的资源，链接如下：http://pan.baidu.com/s/1c02PtYC，解压得到SB5文件夹，里面有书籍的课程源码以及GLTools库。

2.依次点击Xcode-->Preferences-->Locations-->Sources Trees,再点“+”号按钮添加Name:  GLTOOLS_INCLUDE,  Display Name:  GLTools include Folder, Path: ~/Desktop/SB5/src/GLTools/include(本人解压的SB5文件夹在桌面，读者可以根据自己情况添加)。

3.Xcode下新建一个Cocoa工程，命名Triangle，删除项目下得AppDelegate.*两个文件和main.m文件。

4.点击项目-->TARGETS-->Build Settings-->Header Search Paths,添加 $(GLTOOLS_INCLUDE)；然后同样的点击项目-->TARGETS-->Build Phases-->Link Binary With Libraries,点击“+”号添加，GLUT.framework,OpenGL.framework,点击Add Other添加桌面/SB5/Src/GLTools/libGLTools.a文件

5.右击项目-->New File-->C++ File,新增一个Triangle.cpp(不需要头文件)，将下面代码拷贝：

//
//  Triangle.cpp
//  Triangle

// Triangle.cpp
// Our first OpenGL program that will just draw a triangle on the screen.

#include <GLTools.h>            // OpenGL toolkit
#include <GLShaderManager.h>    // Shader Manager Class

#ifdef __APPLE__
#include <glut/glut.h>          // OS X version of GLUT
#else
#define FREEGLUT_STATIC
#include <GL/glut.h>            // Windows FreeGlut equivalent
#endif

GLBatch    triangleBatch;
GLShaderManager    shaderManager;

///////////////////////////////////////////////////////////////////////////////
// Window has changed size, or has just been created. In either case, we need
// to use the window dimensions to set the viewport and the projection matrix.
void ChangeSize(int w, int h)
{
    glViewport(0, 0, w, h);
}

///////////////////////////////////////////////////////////////////////////////
// This function does any needed initialization on the rendering context.
// This is the first opportunity to do any OpenGL related tasks.
void SetupRC()
{
    // Blue background
    glClearColor(0.0f, 0.0f, 1.0f, 1.0f );

    shaderManager.InitializeStockShaders();

    // Load up a triangle
    GLfloat vVerts[] = { -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();
}

///////////////////////////////////////////////////////////////////////////////
// Called to draw scene
void RenderScene(void)
{
    // Clear the window with current clearing color
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);

    GLfloat vRed[] = { 1.0f, 0.0f, 0.0f, 1.0f };
    shaderManager.UseStockShader(GLT_SHADER_IDENTITY, vRed);
    triangleBatch.Draw();

    // Perform the buffer swap to display back buffer
    glutSwapBuffers();
}

///////////////////////////////////////////////////////////////////////////////
// Main entry point for GLUT based programs
int main(int argc, 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));
        return 1;
    }

    SetupRC();

    glutMainLoop();
    return 0;
}

6.cmd + R运行，就可以看到：

OK,第一个三角形成功出现（PS:本人第一次写博客，咳咳，很多不完善，见谅哦）。
