【OpenGL】xcode+glfw画三角形

环境搭建

1. 执行brew install glfw

2. 项目中Build Settings中header Search Paths中添加glfw的include路径

3. 项目中Build Phases中的Link Binary With Libraries中添加glfw的lib文件（路径/opt/homebrew/Cellar/glfw/3.4/lib/libglfw.3.4.dylib）及opengl.framework

代码实现

#include <GLFW/glfw3.h>int main(void)
{GLFWwindow* window;/* Initialize the library */if (!glfwInit())return -1;/* Create a windowed mode window and its OpenGL context */window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);if (!window){glfwTerminate();return -1;}/* Make the window's context current */glfwMakeContextCurrent(window);/* Loop until the user closes the window */while (!glfwWindowShouldClose(window)){/* Render here */glClear(GL_COLOR_BUFFER_BIT);glBegin(GL_TRIANGLES);glVertex2f(0, 0.5f);glVertex2f(-0.5f, -0.5f);glVertex2f(0.5f, -0.5f);glEnd();/* Swap front and back buffers */glfwSwapBuffers(window);/* Poll for and process events */glfwPollEvents();}glfwTerminate();return 0;
}
