一. 例子
按照下面的步驟完成后就可以得倒如下的例子?? Github
二. 準備資源庫
資源庫圖片.png
資源庫可以在這下載
三. 配置 OpenGL 環(huán)境
1.創(chuàng)建項目 Xcode -> macOS -> App
項目創(chuàng)建.png
2.AppDelegate.h、AppDelegate.m豪嗽、main.m、ViewController.h、 ViewController.m 刪除
刪除.png
3.創(chuàng)建 main.cpp文件
創(chuàng)建.png
4.添加OpenGl.framework 和 GLUT.framework
添加.png
5.添加前面準備的庫
5.1將庫圖入其中如下圖選擇

5.2完成后如下圖
截屏2020-07-02下午2.54.57.png
6.配置路徑GLTools.h,glew.h Bulid Settings Header Search path GLTool.h glew.h

四.添加代碼測試

}
void setupRC()
{

GLfloat vVerts[] = {
-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;
}
