直接调用工厂函数

* 模块加载方法 * @param {string} name 模块名称 * @param {string} path 外部脚本的加载路径

* Add class with compatibility for SVG since classList is not supported on * SVG elements in IE

* @param {THREE.BufferGeometry} geometry * @param {GLTF.Primitive} primitiveDef * @param {GLTFParser} parser * @return {Promise<THREE.BufferGeom

* Call callbacks, potentially run async with the main animation thread.

* Call the begin method of an animation in a separate function so it can * benefit from JIT compiling while still having a try/catch block.

* Camelcase a property name into its JavaScript notation (e.g. * "background-color" ==> "backgroundColor"). Camelcasing is used to * normalize p

* Check if an animation should be paused / resumed.

* Check if an animation should be finished, and if so we set the tweens to * the final value for it, then call complete.

* Check if an animation should be stopped, and if so then set the STOPPED * flag on it, then call complete.
