我已经完成了一个简单的html来使用three.js及其gltfloader.js加载gltf模型,它在Mozilla上完美运行,但即使没有错误也没有在ie11上显示。我曾尝试使用es6-promise pollyfill,但似乎无法正常工作。我需要它才能在Internet Explorer上工作。我将代码放在此处,主要是示例代码中的复制粘贴。

    <html>
        <head>
            <meta http-equiv="X-UA-Compatible" content="IE=edge" />
            <title>My first three.js app</title>
            <style>
                body { margin: 0; }
                canvas { width: 100%; height: 100% }
            </style>
        </head>
        <body>
            <script src="js/three.js"></script>
            <script src="js/GLTFLoader.js"></script>
            <script src="js/OrbitControl.js"></script>
            <script src="js/es6-promise.min.js"></script>
            <script src="js/es6-promise.js"></script>
            <script src="js/es6-promise.auto.js"></script>      

            <script>
                var scene = new THREE.Scene();
                var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 );
                var controls = new THREE.OrbitControls( camera );
                var renderer = new THREE.WebGLRenderer();
                renderer.setSize( window.innerWidth, window.innerHeight );
                document.body.appendChild( renderer.domElement );
                controls.screenSpacePanning = true;

                scene.background = new THREE.Color( 0xefe3a7 );
                camera.position.z = 5;
                controls.update();

                var geometry = new THREE.BoxGeometry( 1, 1, 1 );
                var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
                var cube = new THREE.Mesh( geometry, material );
                scene.add( cube );

                var animate = function () {
                    requestAnimationFrame( animate );

                    renderer.render( scene, camera );
                };

                    light = new THREE.HemisphereLight( 0xbbbbff, 0x444422 );
                    light.position.set( 0, 1, 0 );
                    scene.add( light );

                // Instantiate a loader
                var loader = new THREE.GLTFLoader();


                // Load a glTF resource
                loader.load(
                    // resource URL
                    'DUCK/Duck.gltf',
                    // called when the resource is loaded
                    function ( gltf ) {

                        scene.add( gltf.scene );

                        gltf.animations; // Array<THREE.AnimationClip>
                        gltf.scene; // THREE.Scene
                        gltf.scenes; // Array<THREE.Scene>
                        gltf.cameras; // Array<THREE.Camera>
                        gltf.asset; // Object

                    },
                    // called while loading is progressing
                    function ( xhr ) {

                        console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );

                    },
                    // called when loading has errors
                    function ( error ) {

                        console.log( 'An error happened' );

                    }

                );
                animate();
            </script>
        </body>
    </html>

编辑:该框仅供参考,表明只有gltf模型不起作用,该框在ie11上显示正常。

编辑2 :Threejs网站上的gltf loader example在ie11上也不起作用。这是否意味着加载程序与ie11不兼容?

答案 0 :(得分:0)

这是我的解决方法:

  1. 在html中导入ES6支持polyfill

    <script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.auto.js"></script>

  2. 如果您的页面仍未显示gltf模型,则可能需要执行以下操作: 更改GLTFLoader.js中的功能 parse

    var json = JSON.parse(content)

    var json = eval('('+content+')')
