three.js 加载了大对象osgb，请问如何添加到场景中

var loader = new THREE.XHRLoader();// loader.load( 'skinned/UCS_config.json', function ( text ) {loader.setResponseType("blob");loader.load('data/Production_1/Data/Model/Model.lob', function (text) {//var config = JSON.parse( text );var blob = text;if(blob instanceof Blob){var reader = new FileReader();reader.readAsBinaryString(blob);var imgFlag;// 当读取操作成功完成时调用.reader.onload = function(evt){if(evt.target.readyState == FileReader.DONE){var imgFlag = evt.target.result;document.getElementById("info").innerHTML=imgFlag.toString();//这是错误的，，，imgFlag 是我获取的二进制osgb流，，如何添加到场景中？？？请问各位//var material = new THREE.MeshBasicMaterial( {color: 0xffff00, side: THREE.DoubleSide} );//var plane = new THREE.Mesh( imgFlag, material );// scene.add( plane );// window.URL = window.URL || window.webkitURL;// var source = window.URL.createObjectURL(blob);//console.log(source)}}}});
