cannot use/import GLTFLoader and OrbitControls from threejs in my project


Hello so I am trying to build a simple threeJs project. I want to load a 3dModel with GLTFLoader but I cannot import it. Then I have tried to import OrbitControls and I got the same error. I need a little bit of help and can someone explain to me what I am doing wrong? Ass you will see, I have copied only the necessary files into my project folder. Is this a bad thing? Is this the reason for why it's not working?

I want to specify that I have copied those files from a folder that I have download it from three.js website. both files are from -three/examples/jsm/loaders/GLTFLoader.js -three/examples/jsm/controlers/OrbitControls.js

this is my ar.js file

    import * as THREE from "../scripts/three.module.js";
import { GLTFLoader } from "../scripts/GLTFLoader";
import { OrbitControls } from "../scripts/OrbitControls";

const canvas = document.getElementById("webgl");
canvas.style.width = "600";

let scene, camera, renderer;
let obj;

init();
animate();

function init() {
  scene = new THREE.Scene();

  camera = new THREE.PerspectiveCamera(
    70,
    window.innerWidth / window.innerHeight,
    0.01,
    60
  );

  renderer = new THREE.WebGLRenderer({
    canvas: canvas,
  });
  renderer.setPixelRatio(window.devicePixelRatio);
  renderer.setSize(window.innerWidth, window.innerHeight);

  //   /////////////// this is just a test to see if everything works/////////////////
  //   const geometry = new THREE.BoxBufferGeometry(0.3, 0.3, 0.3);
  //   const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
  //   const cube = new THREE.Mesh(geometry, material);
  //   cube.position.set(0, 0, -1);
  //   scene.add(cube);

  let loader = new GLTFLoader();
  loader.load(
    "../assets/3dmodel/firstPinBlue.gltf",
    function (gltf) {
      obj = gltf.scene;
      obj.scale.set(0.3, 0.3, 0.3);
      obj.position.set(0, 0, -4);
      scene.add(gltf.scene);
    },
    undefined,
    function (error) {
      console.log(error);
    }
  );

  const light = new THREE.AmbientLight();
  scene.add(light);

  window.addEventListener("resize", onWindowResize, false);
}

const controls = new OrbitControls(camera, renderer.domElement);

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

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

function animate() {
  renderer.setAnimationLoop(render);
  controls.update();
}

function render() {
  renderer.render(scene, camera);
}

this is the error that I get ERROR IMG


Solution

  • Try loading Three from a CDN like this:

    * {
      box-sizing: border-box;
      margin: 0;
      padding: 0;
    }
    
    canvas {
      display: block;
    }
    <script type="module">
      import * as THREE from "https://cdn.jsdelivr.net/npm/[email protected]/build/three.module.js";
      import { OrbitControls } from "https://cdn.jsdelivr.net/npm/[email protected]/examples/jsm/controls/OrbitControls.js";
    
      const renderer = new THREE.WebGLRenderer();
      renderer.setSize(window.innerWidth, window.innerHeight);
      document.body.appendChild(renderer.domElement);
    
      const cameraMin = 0.0001;
    
      const aspect = window.innerWidth / window.innerHeight;
      const camera = new THREE.PerspectiveCamera(75, aspect, cameraMin, 1000);
      const controls = new OrbitControls(camera, renderer.domElement);
    
      const scene = new THREE.Scene();
    
      camera.position.z = 5;
    
      const cube = new THREE.Mesh(
        new THREE.BoxBufferGeometry(),
        new THREE.MeshNormalMaterial()
      );
    
      scene.add(cube);
    
      (function animate() {
        requestAnimationFrame(animate);
    
        renderer.setSize(window.innerWidth, window.innerHeight);
        camera.aspect = window.innerWidth / window.innerHeight;
        camera.updateProjectionMatrix();
    
        controls.update();
    
        renderer.render(scene, camera);
      })();
    </script>
