ThreeWP is a WordPress plugin that integrates the Three.js library and its addons into your WordPress site using a custom bundle file. This setup allows you to create and manage custom 3D models, animations, and interactive graphics directly within your WordPress theme or custom JavaScript code.
The source code for the minified JavaScript bundle file used in this plugin is publicly available at the following URL: https://github.com/rondevs/threejs-custom-bundler
After activating the plugin, Use the [use_threewp] shortcode to enable Three.js for specific pages. Three.js and its addons will be available for use in your theme or custom JavaScript files. You need to manually add your Three.js code to create and manage 3D content.
Add Custom JavaScript:
– Add your Three.js initialization and rendering code to your theme’s JavaScript file or use a custom script. Here’s a basic example:
document.addEventListener(‘DOMContentLoaded’, function () {
if (typeof ThreeWP !== ‘undefined’) {
// Destructure THREE and THREE_ADDONS from ThreeWP
const { THREE, OrbitControls } = ThreeWP;
// Create a scene
const scene = new THREE.Scene();
// Setup a camera
const camera = new THREE.PerspectiveCamera(
75,
window.innerWidth / window.innerHeight,
0.1,
1000,
);
// Setup a renderer
const renderer = new THREE.WebGLRenderer();
// Give the renderer a width and height
renderer.setSize(window.innerWidth, window.innerHeight);
// Append the renderer into the html body
document.body.appendChild(renderer.domElement);
// Set camera position
camera.position.z = 2;
// Load a texture
const textureLoader = new THREE.TextureLoader();
const texture = textureLoader.load(
'https://threejsfundamentals.org/threejs/resources/images/wall.jpg',
); // Replace with your image URL
// Create geometry
const geometry = new THREE.BoxGeometry(1, 1, 1);
// Create material
const material = new THREE.MeshStandardMaterial({ map: texture });
// Combine into mesh
const sphere = new THREE.Mesh(geometry, material);
scene.add(sphere);
const light = new THREE.AmbientLight(0xffffff);
scene.add(light);
// Set up OrbitControls
const controls = new OrbitControls(
camera,
renderer.domElement,
);
// Optional: Adjust controls settings (e.g., damping, auto-rotation)
controls.enableDamping = true; // Adds smoothness when dragging
controls.dampingFactor = 0.03;
controls.autoRotate = true;
controls.autoRotateSpeed = 2;
function animate(t = 0) {
requestAnimationFrame(animate);
controls.update();
renderer.render(scene, camera);
}
animate();
// Responsive
window.addEventListener('resize', () => {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize(window.innerWidth, window.innerHeight);
});
} else {
console.error('Three.js could not be loaded.');
}
});
NOTE: Destructure THREE and the addons to access from ThreeWP bundle.
Responsive Design: Adjust the size of the Three.js container or renderer according to your design requirements. Handle window resizing events to keep the 3D content responsive.
Documentation: Refer to the Three.js documentation for detailed information on creating more complex scenes, objects, and animations.
defer attribute to the Three.js script for improved performance and load times.*Introduced custom bundle file integration for Three.js and essential addons like OrbitControls, GLTFLoader, EffectComposer, and BloomPass etc.
*This version enhances the plugin’s capabilities and provides a more comprehensive setup for integrating Three.js with WordPress.
