最近似乎OBJMTLLoader has been removed(r74?),但我无法找到有关如何使用这两个替换类的任何文档。这是我目前的代码(改编自Three.js Cookbook):
<script src="../libs/three.r74.js"></script>
<script src="../libs/MTLLoader.js"></script>
<script src="../libs/OBJMTLLoader.js"></script>
<script>
var legoManMesh = null;
function init(){ /* Create my scene here */ }
var loader = new THREE.OBJMTLLoader();
loader.load("../assets/models/lego.obj", "../assets/models/lego.mtl",
function (obj) {
legoManMesh = obj;
init();
}
);
</script>
(顺便说一下,当从r69转到r74时,上面的代码失败了“TypeError:loader.setCrossOrigin不是函数”)

以下是演示如何在r74中加载.obj和.mtl文件的代码:
var mesh = null;
var mtlLoader = new THREE.MTLLoader();
mtlLoader.setPath( "https://threejs.org/examples/models/obj/walt/" );
mtlLoader.load( 'WaltHead.mtl', function( materials ) {
materials.preload();
var objLoader = new THREE.OBJLoader();
objLoader.setMaterials( materials );
objLoader.setPath( "https://threejs.org/examples/models/obj/walt/" );
objLoader.load( 'WaltHead.obj', function ( object ) {
mesh = object;
mesh.position.y = -50;
scene.add( mesh );
} );
} );
