WebGl / Three.js-场景未加载

问题描述 投票:0回答:1

我正在尝试渲染基本的Three.js场景。

这是代码:

<!DOCTYPE html>

<html>

<head>
    <title>Example 01.02 - First Scene</title>
    <script type="text/javascript" src="../libs/three.js"></script>
    <style>
        body {
            /* set margin to 0 and overflow to hidden, to go fullscreen */
            margin: 0;
            overflow: hidden;
        }
    </style>
</head>
<body>

<!-- Div which will hold the Output -->
<div id="WebGL-output">
</div>

<!-- Javascript code that runs our Three.js examples -->
<script type="text/javascript">

    // once everything is loaded, we run our Three.js stuff.
    function init() {

        // create a scene, that will hold all our elements such as objects, cameras and lights.
        var scene = new THREE.Scene();

        // create a camera, which defines where we're looking at.
        var camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 0.1, 1000);

        // create a render and set the size
        var renderer = new THREE.WebGLRenderer();
        renderer.setClearColorHex();
        renderer.setClearColor(new THREE.Color(0xEEEEEE));
        renderer.setSize(window.innerWidth, window.innerHeight);

        // show axes in the screen
        var axes = new THREE.AxisHelper(20);
        scene.add(axes);

        // create the ground plane
        var planeGeometry = new THREE.PlaneGeometry(60, 20);
        var planeMaterial = new THREE.MeshBasicMaterial({color: 0xcccccc});
        var plane = new THREE.Mesh(planeGeometry, planeMaterial);

        // rotate and position the plane
        plane.rotation.x = -0.5 * Math.PI;
        plane.position.x = 15;
        plane.position.y = 0;
        plane.position.z = 0;

        // add the plane to the scene
        scene.add(plane);

        // create a cube
        var cubeGeometry = new THREE.BoxGeometry(4, 4, 4);
        var cubeMaterial = new THREE.MeshBasicMaterial({color: 0xff0000, wireframe: true});
        var cube = new THREE.Mesh(cubeGeometry, cubeMaterial);

        // position the cube
        cube.position.x = -4;
        cube.position.y = 3;
        cube.position.z = 0;

        // add the cube to the scene
        scene.add(cube);

        // create a sphere
        var sphereGeometry = new THREE.SphereGeometry(4, 20, 20);
        var sphereMaterial = new THREE.MeshBasicMaterial({color: 0x7777ff, wireframe: true});
        var sphere = new THREE.Mesh(sphereGeometry, sphereMaterial);

        // position the sphere
        sphere.position.x = 20;
        sphere.position.y = 4;
        sphere.position.z = 2;

        // add the sphere to the scene
        scene.add(sphere);

        // position and point the camera to the center of the scene
        camera.position.x = -30;
        camera.position.y = 40;
        camera.position.z = 30;
        camera.lookAt(scene.position);

        // add the output of the renderer to the html element
        document.getElementById("WebGL-output").appendChild(renderer.domElement);

        // render the scene
        renderer.render(scene, camera);
    }
    window.onload = init;

</script>
</body>
</html>

这是一个HTML文件,我将其拖放到浏览器中。在与该文件相同的目录中,我有一个名为libs的文件夹,在内部有three.jsthree.mini.js库。

我从其网站下载了three.js zip文件,里面有很多文件。但是由于这些库是代码所需的库,因此我只放置了这两个javascript文件,而忽略了zip文件中包含的所有其他文件。

[当我将html文件拖放到浏览器上时,我唯一看到的是空白的空白图像。

编辑:JS控制台错误:

*Failed to load resource: net::ERR_FILE_NOT_FOUND
*Uncaught ReferenceError: THREE is not defined at init (test.html:29)

您是否尝试按照描述的here在本地运行事物?

我个人使用的是python版本:

如果您安装了Python,则足以从命令行(从您的工作目录)运行此命令:// Python 2.xpython -m SimpleHTTPServer// Python 3.xpython -m http.server这将为当前目录中位于8000端口下本地主机的文件提供服务,即在地址栏中键入:http://localhost:8000/

然后,您可以访问文件浏览到本地主机(由于网络浏览器上的资源访问策略发生变化,因此现在必须这样做)。>>

[在测试您的代码之后,实际上我只是删除了renderer.setClearColorHex();第36行,并将其放置在包含three.min.js的文件夹中,当我从文件夹中打开它时,它工作正常。
