Three.js Import 3d Model


i have followed a couple of tutorials to import a 3d model. I have succeeded importing using A-Frame Tags, but when i try doing it with Three.js its not working. I have copy pasted the following code from a tutorial i found on youtube. https://www.youtube.com/watch?v=1TeMXIWRrqE

      let scene, camera, renderer;
      function init() {
        scene = new THREE.Scene();
        scene.background = new THREE.Color(0xdddddd);
        camera = new THREE.PerspectiveCamera(40,window.innerWidth/window.innerHeight,1,5000);
        camera.rotation.y = 45/180*Math.PI;
        camera.position.x = 800;
        camera.position.y = 100;
        camera.position.z = 1000;

        controls = new THREE.OrbitControls(camera);
        controls.addEventListener('change', renderer);

        hlight = new THREE.AmbientLight (0x404040,100);
        scene.add(hlight);

        directionalLight = new THREE.DirectionalLight(0xffffff,100);
        directionalLight.position.set(0,1,0);
        directionalLight.castShadow = true;
        scene.add(directionalLight);
        light = new THREE.PointLight(0xc4c4c4,10);
        light.position.set(0,300,500);
        scene.add(light);
        light2 = new THREE.PointLight(0xc4c4c4,10);
        light2.position.set(500,100,0);
        scene.add(light2);
        light3 = new THREE.PointLight(0xc4c4c4,10);
        light3.position.set(0,100,-500);
        scene.add(light3);
        light4 = new THREE.PointLight(0xc4c4c4,10);
        light4.position.set(-500,300,500);
        scene.add(light4);
        renderer = new THREE.WebGLRenderer({antialias:true});
        renderer.setSize(window.innerWidth,window.innerHeight);
        document.body.appendChild(renderer.domElement);
        
        let loader = new THREE.GLTFLoader();
        loader.load('Model/scene.gltf', function(gltf){
          car = gltf.scene.children[0];
          car.scale.set(0.5,0.5,0.5);
          scene.add(gltf.scene);
          animate();
          
        });
      }
      function animate() {
        renderer.render(scene,camera);
        requestAnimationFrame(animate);
      
      }
      init();
    </script>
  </body>
</html>

The error it gives me...

    at new THREE.OrbitControls (OrbitControls.js:1101)
    at init (index.html:22)
    at index.html:62

Thanks in advance.


Solution

  • You're missing an argument when initiating new THREE.OrbitControls(); It's expecting a camera and an HTMLElement, but you're only passing the camera. See the docs here. You can fix it by adding the renderer's canvas:

    renderer = new THREE.WebGLRenderer({antialias:true});
    document.body.appendChild(renderer.domElement);
    controls = new THREE.OrbitControls(camera, renderer.domElement);
