API Reference

v1

three-vrm v1 has been released!

three-vrm v1 supports VRM1.0, which is a new version of VRM format (the previous version of VRM is also supported, don't worry!). It also adopts the GLTFLoader plugin system which is a relatively new feature of GLTFLoader.

There are a lot of breaking changes! See the migration guide for more info.

How to Use

from HTML

You will need:

• Three.js build
• GLTFLoader
• A build of @pixiv/three-vrm
  • .module ones are ESM, otherwise it's UMD and injects its modules into global THREE
  • .min ones are minified (for production), otherwise it's not minified and it comes with source maps

You can import all of them via CDN. See the example below.

Code like this:

<script type="importmap">
  {
    "imports": {
      "three": "https://cdn.jsdelivr.net/npm/three@0.164.1/build/three.module.js",
      "three/addons/": "https://cdn.jsdelivr.net/npm/three@0.164.1/examples/jsm/",
      "@pixiv/three-vrm": "three-vrm.module.js"
    }
  }
</script>

<script type="module">
  import * as THREE from 'three';
  import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
  import { VRMLoaderPlugin } from '@pixiv/three-vrm';

  const scene = new THREE.Scene();

  const loader = new GLTFLoader();

  // Install GLTFLoader plugin
  loader.register((parser) => {
    return new VRMLoaderPlugin(parser);
  });

  loader.load(
    // URL of the VRM you want to load
    '/models/VRM1_Constraint_Twist_Sample.vrm',

    // called when the resource is loaded
    (gltf) => {
      // retrieve a VRM instance from gltf
      const vrm = gltf.userData.vrm;

      // add the loaded vrm to the scene
      scene.add(vrm.scene);

      // deal with vrm features
      console.log(vrm);
    },

    // called while loading is progressing
    (progress) => console.log('Loading model...', 100.0 * (progress.loaded / progress.total), '%'),

    // called when loading has errors
    (error) => console.error(error),
  );
</script>

via npm

Install three and @pixiv/three-vrm :

npm install three @pixiv/three-vrm

Code like this:

import * as THREE from 'three';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader';
import { VRMLoaderPlugin } from '@pixiv/three-vrm';

const scene = new THREE.Scene();

const loader = new GLTFLoader();

// Install GLTFLoader plugin
loader.register((parser) => {
  return new VRMLoaderPlugin(parser);
});

loader.load(
  // URL of the VRM you want to load
  '/models/VRM1_Constraint_Twist_Sample.vrm',

  // called when the resource is loaded
  (gltf) => {
    // retrieve a VRM instance from gltf
    const vrm = gltf.userData.vrm;

    // add the loaded vrm to the scene
    scene.add(vrm.scene);

    // deal with vrm features
    console.log(vrm);
  },

  // called while loading is progressing
  (progress) => console.log('Loading model...', 100.0 * (progress.loaded / progress.total), '%'),

  // called when loading has errors
  (error) => console.error(error),
);
