Port morphtargets/face example to vite.js

Hello,

I’m trying to port this example (three.js examples) to vite.js.

At this point we are doing this because we later want to deal with other glb/gltf models and control them in interactive art situations.

My main.js file is like that:

import * as THREE from 'three';
import Stats from 'three/addons/libs/stats.module.js';
import { OrbitControls } from 'three/addons/controls/OrbitControls.js';
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
import { KTX2Loader } from 'three/addons/loaders/KTX2Loader.js';
import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';
import { RoomEnvironment } from 'three/addons/environments/RoomEnvironment.js';
import { GUI } from 'three/addons/libs/lil-gui.module.min.js';

init();

function init() {

  let mixer;

  const clock = new THREE.Clock();

  const container = document.createElement( 'div' );
  document.body.appendChild( container );

  const camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 20 );
  camera.position.set( - 1.8, 0.8, 3 );

  const scene = new THREE.Scene();

  const renderer = new THREE.WebGLRenderer( { antialias: true } );
  renderer.setPixelRatio( window.devicePixelRatio );
  renderer.setSize( window.innerWidth, window.innerHeight );
  renderer.toneMapping = THREE.ACESFilmicToneMapping;

  container.appendChild( renderer.domElement );

  const ktx2Loader = new KTX2Loader()
    .setTranscoderPath( 'three/examples/jsm/libs/basis/' )
    .detectSupport( renderer );

  new GLTFLoader()
    .setKTX2Loader( ktx2Loader )
    .setMeshoptDecoder( MeshoptDecoder )
    .load( './models/facecap.glb', ( gltf ) => {

      const mesh = gltf.scene.children[ 0 ];

      scene.add( mesh );

      mixer = new THREE.AnimationMixer( mesh );

      mixer.clipAction( gltf.animations[ 0 ] ).play();

      // GUI

      const head = mesh.getObjectByName( 'mesh_2' );
      const influences = head.morphTargetInfluences;

      const gui = new GUI();
      gui.close();

      for ( const [ key, value ] of Object.entries( head.morphTargetDictionary ) ) {

        gui.add( influences, value, 0, 1, 0.01 )
          .name( key.replace( 'blendShape1.', '' ) )
          .listen();

      }

    } );

  const environment = new RoomEnvironment( renderer );
  const pmremGenerator = new THREE.PMREMGenerator( renderer );

  scene.background = new THREE.Color( 0x666666 );
  scene.environment = pmremGenerator.fromScene( environment ).texture;

  const controls = new OrbitControls( camera, renderer.domElement );
  controls.enableDamping = true;
  controls.minDistance = 2.5;
  controls.maxDistance = 5;
  controls.minAzimuthAngle = - Math.PI / 2;
  controls.maxAzimuthAngle = Math.PI / 2;
  controls.maxPolarAngle = Math.PI / 1.8;
  controls.target.set( 0, 0.15, - 0.2 );

  const stats = new Stats();
  container.appendChild( stats.dom );

  renderer.setAnimationLoop( () => {

    const delta = clock.getDelta();

    if ( mixer ) {

      mixer.update( delta );

    }

    renderer.render( scene, camera );

    controls.update();

    stats.update();

  } );

  window.addEventListener( 'resize', () => {

    camera.aspect = window.innerWidth / window.innerHeight;
    camera.updateProjectionMatrix();

    renderer.setSize( window.innerWidth, window.innerHeight );

  } );

}

When I run the server (npm run dev) I get this error in the console: Uncaught SyntaxError: Unexpected identifier ‘html’

I’m trying to understand what’s wrong, but so far I have no success…

Any clues?

It’s most likely something with your vite config - there’s no html in the code you’ve shared, so the error is unrelated to it.
