Three.js is a JavaScript library and API for creating, displaying and animating 3D graphics in a web browser. It leverages WebGL and boasts features like effects, scenes, cameras, animations etc. On the other hand, Spline is a 3D design tool that provides a codeless and designer-friendly interface for building 3D experiences. It offers collaboration features, simplifies importing, and supports diverse export formats, thus enhancing user experience.

Three.js vs Spline

Key Differences Between Three.js and Spline

  • Coding: Three.js utilizes JavaScript and GLSL for 3D modeling, whereas Spline offers a codeless design paradigm.
  • User Interface: Spline has an interactive and simplified user interface, in contrast to Three.js’s more technical and code-oriented approach.
  • Collaboration: Unlike Three.js, Spline facilitates collaboration, allowing real-time fine-tuning and commenting.

What Is Three.js and Who’s It For?

Three.js is a cross-browser JavaScript library and API that enables the creation and display of animated 3D computer graphics in a web browser, without the need for any plugins. It was first released by Ricardo Cabello on Github in 2010 and leverages WebGL for accelerated GPU optimization. High-level libraries like Three.js simplify the development of complex 3D animations. It’s intended for both developers and designers wanting to add interactive 3D elements to their webpages.

Three.js vs Spline: Pricing Breakdown

While Three.js maintains its open source advantage at no cost, Spline starts at $9 per month with added features for professional and team use.

Three.js

Maintaining its commitment to the open-source community, Three.js operates under the MIT License, granting free use and access to its powerful and robust 3D web animation capabilities.

Spline

Spline offers a freemium tier while introducing subscription packages starting at $9/month/user for a personal plan, escalating to $12/month/user for a team plan that offers unlimited files, projects, folders, and the removal of the Spline logo.

Code Examples for Three.js & Spline

Three.js

This snippet uses three.js to create a rotating 3D icosahedron with textured faces. Ensure three.js library is linked in your HTML file.

var scene = new THREE.Scene();var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 );var renderer = new THREE.WebGLRenderer();renderer.setSize( window.innerWidth, window.innerHeight );document.body.appendChild( renderer.domElement );var geometry = new THREE.IcosahedronGeometry();var material = new THREE.MeshBasicMaterial( {color: 0x00ff00, wireframe: true} );var ico = new THREE.Mesh( geometry, material );scene.add( ico );camera.position.z = 5;function animate() {requestAnimationFrame( animate );ico.rotation.x += 0.01;ico.rotation.y += 0.01;renderer.render( scene, camera );}animate();

Spline

This Spline code creates a 3D cubic spline with five points. The THREE.SplineCurve3 needs the three.js library to function perfectly.

var points = [new THREE.Vector2(0, 0),new THREE.Vector2(1, 1),new THREE.Vector2(2, 0.5),new THREE.Vector2(3, 0.5),new THREE.Vector2(4, 1),];var path = new THREE.SplineCurve3(points);var tubeGeometry = new THREE.TubeGeometry(path, 100, 2, 8, false);var mesh = new THREE.Mesh(tubeGeometry, new THREE.MeshBasicMaterial({color: 0xff0000}));scene.add(mesh);

Three.js or Spline: Pick Your Power Tool

In the sphere of 3D creation and AR/VR, we turn the lights on two towering tech: Three.js and Spline. But which one best provides for your particular needs? Let’s sieve through a few spheres:

Web Developers and 3D Animators

The seasoned web developer or 3D animator hungry for granular control may lean towards Three.js. With its potent set of tools, including multiple effects, cameras, lights, shaders, and its support for Virtual and Augmented Reality via WebXR, Three.js is a vast landscape for intricate animation and modeling projects.
