What Is OpenGL and Who’s It For?

Initiated by Silicon Graphics in 1992, OpenGL (Open Graphics Library) is a robust, low-level rendering and modelling software library. This powerful tool provides hardware-accelerated 3D graphics that have been extensively utilized in video games, CAD, and scientific applications. Primarily, OpenGL is tailored to developers and designers familiar with C++ programming and seeking to venture into the realms of 3D graphics and Augmented & Virtual Reality.

Pros of OpenGL

• Continual development and improvements since 1992
• Supported by industry leaders in hardware and software
• Widely used in various fields from gaming to science

Cons of OpenGL

• Requires advanced C++ programming skills
• Understanding of complex mathematics necessary
• Lower-level API can be more difficult to work with than higher-level alternatives

Babylon.js vs OpenGL: Pricing

Essentially, both Babylon.js and OpenGL are open-source technologies, making them free for users, although the cost may vary depending on how users choose to utilize them in their projects.

Babylon.js

Being an open-source technology, Babylon.js is freely available to users. Its repository is hosted on GitHub under the Apache License 2.0, which means you can use, modify, distribute, and even sell your software using Babylon.js without the need to pay any fees. The cost comes in the form of the development and maintenance of the projects you create with the engine.

OpenGL

Like Babylon.js, OpenGL is also open-source, hence free of charge. Developed and managed by the Khronos Group, this library is a standard in the industry for hardware-accelerated 3D graphics. The cost of using OpenGL comes into play based on how you utilize its advanced rendering properties and the potential prerequisite knowledge of C++ programming that may be required to use it effectively.

Code Examples for Babylon.js & OpenGL

Babylon.js

This code demonstrates an interactive Babylon.js scene creating a spiral of spheres. Prerequisites: Familiarity with Babylon.js and latest version of Babylon.js library installed.

var createScene = function () {
    var scene = new BABYLON.Scene(engine);
    var camera = new BABYLON.FreeCamera("camera", new BABYLON.Vector3(0, 0, -10), scene);
    for (var index = 0; index < 50; index++) {
        var sphere = BABYLON.Mesh.CreateSphere("sphere", 10, 1.0, scene);
        sphere.position.x = index;
        sphere.position.y = Math.sin(index / 3) * 10;
        sphere.position.z = Math.cos(index / 3) * 10;
    }
    return scene;
};
var engine = new BABYLON.Engine(canvas, true);
var scene = createScene();
engine.runRenderLoop(function () {
    scene.render();
});

OpenGL

The OpenGL code example provided generates a rotating 3D pyramid. Prerequisites: A foundational understanding of OpenGL, and installation of GLFW and GLEW libraries.

#include <glew.h>
#include <glfw3.h>
GLFWwindow* window;
int main(void)
{
    // 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))
    {
        glClear(GL_COLOR_BUFFER_BIT);
        // Render OpenGL here
        glRotatef(0.01f, 0.0f, 1.0f, 0.0f);
        glBegin(GL_TRIANGLES);
        glVertex3f(-0.5f, -0.5f, 0.0f);
        glVertex3f(0.5f, -0.5f, 0.0f);
        glVertex3f(0.0f, 0.5f, 0.0f);
        glEnd();
        // Swap front and back buffers
        glfwSwapBuffers(window);
        // Poll for and process events
        glfwPollEvents();
    }
    glfwTerminate();
    return 0;
}
