准备工作：
1.资源包下载：链接: https://pan.baidu.com/s/19jAhEYW0Mxkuj2vrKNpeyg 密码: bf5h
2.代码项目实例：https://github.com/Likoo7072/OpenGL.git
开始搭建
1.Xcode -> macOS -> APP
2.添加OpenGl.framework 和GLUT.framework系统库
3 .把下载解压好的CLTools.h,glew.h,libGLTools.a资源库拖入到项目中
A：libGLTools.a 直接拖到工程的Frameworks文件里面，另外删除 AppDelegate.h ，AppDelegate.m ，main.m ，ViewController.h ViewController.m ; 创建 main.cpp
B：配置资源库的引入（"$(SRCROOT)/OpenGlShare/include"）
4.在main.cpp复制运行下面的代码
#include "GLTools.h"#include <glut/glut.h>
GLBatch triangleBatch;
GLShaderManager shaderManager;
//0,0wh
void ChangeSize(int w,int h)
{
glViewport(0,0, w, h);
}
//void SetupRC()
{
//glClearColor(0.0f,0.0f,1.0f,1.0f);
//shaderManager.InitializeStockShaders();//vVert3x,y,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();
}
//void RenderScene(void)
{
//glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL
_BUFFER_BIT);
//
GLfloat vRed[] = {1.0f,0.0f,0.0f,1.0f};
//GLT_SHADER_IDENTITY
shaderManager.UseStockShader(GLT_SHADER_IDENTITY,vRed);
//triangleBatch.Draw();//glutSwapBuffers();
}int main(int argc,char* argv[])
{
//MAC OS X
gltSetWorkingDirectory(argv[0]);
//GLUT
glutInit(&argc, argv);
/*GLUT_DOUBLEGLUT_RGBAGLUT_DEPTHGLUT_STENCIL
RGBA*/glutInitDisplayMode(GLUT_DOUBLE|GLUT_RGBA|GLUT_DEPTH|GLUT_
STENCIL);
//GLUTglutInitWindowSize(800,600);
<>“”
glutCreateWindow("Triangle");//glutReshapeFunc(ChangeSize);
glutDisplayFunc(RenderScene);//GLenum err = glewInit();if(GLEW_OK != err) {
fprintf(stderr,"glew error:%s\n",glewGetErrorString(er
r)); return 1;
}
//SetupRCSetupRC();
glutMainLoop();
return 0;
}
5.效果图
