我试图学习OpenGL只是为了消磨时间，只是对计算机图形感到好奇。我在Youtube频道上看了一个速成教程FreeCodeCamp.org this
下面是窗口的基本创建代码，并绘制一些图元。（使用C++和OpenGL）

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

// Vertex Shader source code
const char* vertexShaderSource = "#version 330 core\n"
"layout (location = 0) in vec3 aPos;\n"
"void main()\n"
"{\n"
"   gl_Position = vec4(aPos.x, aPos.y, aPos.z, 1.0);\n"
"}\0";
//Fragment Shader source code
const char* fragmentShaderSource = "#version 330 core\n"
"out vec4 FragColor;\n"
"void main()\n"
"{\n"
"   FragColor = vec4(0.8f, 0.3f, 0.02f, 1.0f);\n"
"}\n\0";


int main()
{
    // Initialize GLFW
    glfwInit();

    // Tell GLFW what version of OpenGL we are using 
    // In this case we are using OpenGL 3.3
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    // Tell GLFW we are using the CORE profile
    // So that means we only have the modern functions
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    //important for macOS users because i dont know it just is
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);

    // Create a GLFWwindow object of 800 by 800 pixels, naming it "YoutubeOpenGL"
    GLFWwindow* window = glfwCreateWindow(800, 800, "YoutubeOpenGL", NULL, NULL);
    // Error check if the window fails to create
    if (window == NULL)
    {
        std::cout << "Failed to create GLFW window and fuck this shit" << std::endl;
        glfwTerminate();
        return -1;
    }
    // Introduce the window into the current context
    glfwMakeContextCurrent(window);

    //Load GLAD so it configures OpenGL
    gladLoadGL();
    // Specify the viewport of OpenGL in the Window
    // In this case the viewport goes from x = 0, y = 0, to x = 800, y = 800
    glViewport(0, 0, 800, 800);


    // Create Vertex Shader Object and get its reference
    GLuint vertexShader = glCreateShader(GL_VERTEX_SHADER);
    // Attach Vertex Shader source to the Vertex Shader Object
    glShaderSource(vertexShader, 1, &vertexShaderSource, NULL);
    // Compile the Vertex Shader into machine code
    glCompileShader(vertexShader);

    // Create Fragment Shader Object and get its reference
    GLuint fragmentShader = glCreateShader(GL_FRAGMENT_SHADER);
    // Attach Fragment Shader source to the Fragment Shader Object
    glShaderSource(fragmentShader, 1, &fragmentShaderSource, NULL);
    // Compile the Vertex Shader into machine code
    glCompileShader(fragmentShader);

    // Create Shader Program Object and get its reference
    GLuint shaderProgram = glCreateProgram();
    // Attach the Vertex and Fragment Shaders to the Shader Program
    glAttachShader(shaderProgram, vertexShader);
    glAttachShader(shaderProgram, fragmentShader);
    // Wrap-up/Link all the shaders together into the Shader Program
    glLinkProgram(shaderProgram);

    // Delete the now useless Vertex and Fragment Shader objects
    glDeleteShader(vertexShader);
    glDeleteShader(fragmentShader);


    // Vertices coordinates
    GLfloat vertices[] =
    {
        -0.5f, -0.5f * float(sqrt(3)) / 3, 0.0f, // Lower left corner
        0.5f, -0.5f * float(sqrt(3)) / 3, 0.0f, // Lower right corner
        0.0f, 0.5f * float(sqrt(3)) * 2 / 3, 0.0f, // Upper corner
    };

    // Create reference containers for the Vartex Array Object and the Vertex Buffer Object
    GLuint VAO[1], VBO[1];

    // Generate the VAO and VBO with only 1 object each
    glGenVertexArrays(1, VAO);
    glGenBuffers(1, VBO);

    // Make the VAO the current Vertex Array Object by binding it
    glBindVertexArray(VAO[0]);

    // Bind the VBO specifying it's a GL_ARRAY_BUFFER
    glBindBuffer(GL_ARRAY_BUFFER, VBO[0]);
    // Introduce the vertices into the VBO
    glBufferData(GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW);

    // Configure the Vertex Attribute so that OpenGL knows how to read the VBO
    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 3 * sizeof(float), (void*)0);
    // Enable the Vertex Attribute so that OpenGL knows to use it
    glEnableVertexAttribArray(0);

    // Bind both the VBO and VAO to 0 so that we don't accidentally modify the VAO and VBO we created
    glBindBuffer(GL_ARRAY_BUFFER, 0);
    glBindVertexArray(0);


    // Main while loop
    while (!glfwWindowShouldClose(window))
    {
        // Specify the color of the background
        glClearColor(0.07f, 0.13f, 0.17f, 1.0f);
        // Clean the back buffer and assign the new color to it
        glClear(GL_COLOR_BUFFER_BIT);
        // Tell OpenGL which Shader Program we want to use
        glUseProgram(shaderProgram);
        // Bind the VAO so OpenGL knows to use it
        glBindVertexArray(VAO[0]);
        // Draw the triangle using the GL_TRIANGLES primitive
        glDrawArrays(GL_TRIANGLES, 0, 3);
        // Swap the back buffer with the front buffer
        glfwSwapBuffers(window);
        // Take care of all GLFW events
        glfwPollEvents();
    }


    // Delete all the objects we've created
    glDeleteVertexArrays(1, VAO);
    glDeleteBuffers(1, VBO);
    glDeleteProgram(shaderProgram);
    // Delete window before ending the program
    glfwDestroyWindow(window);
    // Terminate GLFW before ending the program
    glfwTerminate();
    return 0;
}

但结果我得到的是输出

我想密码是在中间画三角形。

我试着阅读代码并在网上搜索，但我想我甚至不知道该搜索什么，因为我刚接触OpenGL，不知道某些关键字，因为我无法最佳地搜索它。
