GLFW

下载glfw

下载地址

一般解压至项目文件夹

链接

解决方案资源管理器 右键 >> 属性 >> VC++目录

  • 包含目录 添加 include 文件夹路径
  • 库目录 添加 lib 文件夹路径

0

链接器

附加依赖项：手动输入glfw3.lib;opengl32.lib

这时就可以在cpp文件中加入#include <GLFW/glfw3.h>

GLAD

glad提供在线服务 https://glad.dav1d.de/

  • Language：C/C++
  • API gl 选择版本大于等于之前 glfw 版本的选项
  • Profile 选择 Core
  • 勾选 Generate a loader

生成，下载zip文件，获得两个包含头文件的文件夹和一个glad.c文件

包含头文件的文件夹放入 glfw 的 include 下，glad.c 也放入项目中

#include <iostream>
#include <glad/glad.h>
#include <GLFW/glfw3.h>

void framebuffer_size_callback(GLFWwindow* window, int width, int height);
void processInput(GLFWwindow* window);

int main()
{
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    //glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);

    GLFWwindow* window = glfwCreateWindow(800, 600, "LearnOpenGL", NULL, NULL);
    if (window == NULL)
    {
        std::cout << "Failed to create GLFW window" << std::endl;
        glfwTerminate();
        return -1;
    }
    glfwMakeContextCurrent(window);
    if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
    {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }

    glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
    while (!glfwWindowShouldClose(window))
    {

        processInput(window);

        glClearColor(0.2f, 0.3f, 0.3f, 1.0f);
        glClear(GL_COLOR_BUFFER_BIT);

        glfwSwapBuffers(window);
        glfwPollEvents();
    }
    glfwTerminate();
    return 0;
}

void framebuffer_size_callback(GLFWwindow* window, int width, int height)
{
    glViewport(0, 0, width, height);
}

void processInput(GLFWwindow* window)
{
    if (glfwGetKey(window, GLFW_KEY_ESCAPE) == GLFW_PRESS)
        glfwSetWindowShouldClose(window, true);
}

运行成功获得一个如下图窗口，可通过Esc关闭
