How can I create 3D models using C++ and OpenGL?

To create 3D models in C++ with OpenGL, you'll need to set up an OpenGL context and use libraries like GLM for math and Assimp for model loading.

What libraries do I need to install?

You should install GLFW for window management, GLEW for OpenGL function loading, and GLM for mathematics.

Can you give me a simple code example?

Sure! Here's a basic example to initialize OpenGL and create a window:

#include <GL/glew.h>
#include <GLFW/glfw3.h>

int main() {
    glfwInit();
    GLFWwindow* window = glfwCreateWindow(800, 600, "3D Model", NULL, NULL);
    glfwMakeContextCurrent(window);
    glewInit();
    while (!glfwWindowShouldClose(window)) {
        glClear(GL_COLOR_BUFFER_BIT);
        glfwSwapBuffers(window);
        glfwPollEvents();
    }
    glfwTerminate();
    return 0;
}

How do I load a 3D model into this?

You can use the Assimp library to load 3D models. After loading, you'll need to extract the vertex data and send it to OpenGL for rendering.
