一、代码

const canvas = document.querySelector('canvas.webgl')

// Scene
const scene = new THREE.Scene()

 */
const dracoLoader = new DRACOLoader()
dracoLoader.setDecoderPath('/draco/')

const gltfLoader = new GLTFLoader()
gltfLoader.setDRACOLoader(dracoLoader)

let mixer = null

gltfLoader.load(
    '/models/hamburger.glb',
    (gltf) =>
    {
        scene.add(gltf.scene)
    }
)

/**

 */

// Controls

const clock = new THREE.Clock()
let previousTime = 0

const tick = () =>

    const elapsedTime = clock.getElapsedTime()
    const deltaTime = elapsedTime - previousTime

    if(mixer)
    {
        mixer.update(deltaTime)
    }

    // Update controls
    controls.update()

    // Render
    renderer.render(scene, camera)

总结

想学建模，但是没时间！想学three.js，但是忘得差不多了！不想工作，这可怎么办呢。
