Babylon.js and React Three Fiber are two feature-packed technologies for generating 3D graphics in a web browser. Babylon.js is a real-time 3D engine developed by Microsoft, leveraging HTML5 and WebGL. It offers a range of features, including key frame animation and physics engines. React Three Fiber, on the other hand, is a React renderer for three.js. It allows you to create a 3D scene graph efficiently and flexibly, offering excellent performance and supporting all features of Threejs.

Babylon.js and React Three Fiber compared

Key Differences Between Babylon.js and React Three Fiber

  • Original Developer: Babylon.js is a side project of Microsoft employees, while React Three Fiber is an independent project based on three.js.
  • Coding Language: Babylon.js is written in TypeScript and JavaScript, while React Three Fiber is a React-based renderer for three.js.
  • Rendering Method: Babylon.js uses physically based and post-processing rendering methods, while React Three Fiber utilises HTML5 Canvas and WebGL APIs.
  • Use of Physics Engines: Babylon.js incorporates physics engines like Cannon.js and Oimo for real-world simulations, while React Three Fiber depends on React’s scheduling capabilities to improve performance.

Babylon.js vs React Three Fiber: Pricing

Neither Babylon.js nor React Three Fiber comes with a cost, instead, they both can be accessed freely under their respective licensing terms.

Babylon.js

Babylon.js is open-source software, developed and maintained by Microsoft and various contributors. It operates under the Apache License 2.0 and its source code can be found on GitHub. Hence, there’s no direct cost attached to this powerful 3D engine.

React Three Fiber

React Three Fiber, a 3D rendering library for React based on Three.js, is also a free technology. It can be installed via npm and utilized freely. This library essentially brings the power of 3D graphics to the React ecosystem at no actual cost.

Code Examples for Babylon.js & React Three Fiber

Babylon.js: Interactive 3D Sphere

This Babylon.js snippet creates an interactive 3D sphere. Users can rotate this sphere, giving them a 360-degree view. To execute this code, ensure you’ve imported the Babylon.js module.

    // Import Babylon.js
    import * as BABYLON from 'babylonjs';

    // Set up environment
    var canvas = document.getElementById("renderCanvas");
    var engine = new BABYLON.Engine(canvas, true);

    // Scene creation
    var createScene = function () {
        var scene = new BABYLON.Scene(engine);
        var camera = new BABYLON.ArcRotateCamera("camera1", 0, 0, 0, new BABYLON.Vector3(0, 0, -0), scene);

        //Var setting - radius, segments etc.
        var sphere = BABYLON.MeshBuilder.CreateSphere("sphere", {segment:16, diameter:2}, scene);

        return scene;
    };

    // Call the scene
    var scene = createScene();

    // Loop render for continuous rendering
    engine.runRenderLoop(function () {
        scene.render();
    });

React Three Fiber: Rotating Cube with Shadows

Here’s a React Three Fiber code snippet for a rotating cube with cast shadows. The execution of this code requires a working React application and the installation of @react-three/fiber and @react-three/drei.

    // Importing dependencies
import React from 'react'
import { Canvas } from '@react-three/fiber'
import { OrbitControls, Box, softShadows } from '@react-three/drei'
