在MAC上配置OpenGL

准备工作

• CLTools
• glew
• libGLTools.a
  百度云盘地址:http://pan.baidu.com/s/1i4PTEb7 密码 :nbgc

配置

• 打开Xcode -> macOS -> Cocoa Application 创建Mac项目;
• 添加OpenGl.framework GLUT.framework 两个系统库;
• 添加CLTools.h,glew.h,在Bulid Settings中 Header Search path 选项添加CLTool.h 和glew.h 的路径;
• 拖动libGLTools.a静态库到工程的frameworks文件夹中.
• 删除AppDelegate.h /AppDelegate.m /main.m/ViewController.h/ViewController.m,创建main.cpp文件

测试

复制代码到main.cpp文件中

#include "GLShaderManager.h"
#include "GLTools.h"
#include 

GLShaderManager shaderManager;
GLBatch triangleBatch;

void changeSize(int w,int h)
{
    glViewport(0, 0, w, h);
}

void RenderScene(void)
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT);
    GLfloat vRed[] = {1.0,0.0,0.0,1.0f};
    shaderManager.UseStockShader(GLT_SHADER_IDENTITY,vRed);
    triangleBatch.Draw();
    glutSwapBuffers();
}

void setupRC()
{
    glClearColor(0.98f, 0.40f, 0.7f, 1);
    shaderManager.InitializeStockShaders();
    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();
}

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 status = glewInit();
    if (GLEW_OK != status) {
        printf("GLEW Error:%s\n",glewGetErrorString(status));
        return 1;
        
    }
    setupRC();
    glutMainLoop();
    return  0;
}

运行,出现以下结果则证明成功
