'./js/three.module.js'

直接从官网的example里面下载下来就行了。

文档: https://threejs.org/docs/index.html#api/en/loaders/TextureLoader

var texturePainting = new THREE.TextureLoader().load( './image/earth.jpg' );
var materialPainting = new THREE.MeshBasicMaterial( { color: 0xffffff, map: texturePainting } ); //基础材质

//上面两行是贴图材质的写法
mesh = new THREE.Mesh(
     new THREE.SphereBufferGeometry( 100, 42, 42 ),
     materialPainting
);

官方文档的demo还有一个异步的加载

var texture = new THREE.TextureLoader().load( 'textures/land_ocean_ice_cloud_2048.jpg' );

// immediately use the texture for material creation
var material = new THREE.MeshBasicMaterial( { map: texture } );
