Three.js - VRML 加载器 [英] Three.js - VRML Loader

问题描述

我正在尝试将 Three.js 与 VRML (WRL) 模型一起使用.我想知道的是模型加载了各种颜色(彩色).如何将纯色模型加载为原始文件?

我的例子是:http://dev.logicarts.com.br/semapro/projeto-3d/teste-1.html

代码:

<a href="http://threejs.org" target="_blank">three.js</a>——vrml 格式加载器测试 -<!--model from <a href="http://cs.iupui.edu/~aharris/webDesign/vrml/" target="_blank">VRML 2.0 教程</a>,-->
<script src="js/three.min.js"></script><script src="js/OrbitControls.js"></script><script src="js/VRMLLoader.js"></script><script src="js/Detector.js"></script><script src="js/stats.min.js"></script><脚本>if (!Detector.webgl) Detector.addGetWebGLMessage();var 容器，统计数据；var 相机、控件、场景、渲染器；无功十字架；在里面();动画()；函数初始化(){camera = new THREE.PerspectiveCamera( 60, window.innerWidth/window.innerHeight, 0.01, 1e10 );相机.位置.z = 6;控件 = 新的 THREE.OrbitControls( 相机 );control.rotateSpeed = 5.0;control.zoomSpeed = 5;control.noZoom = false;control.noPan = false;场景 = 新的 THREE.Scene();场景添加(相机)；//光var dirLight = new THREE.DirectionalLight(0xffffff);dirLight.position.set( 200, 200, 1000 ).normalize();相机.添加( dirLight );相机.添加( dirLight.target );var loader = new THREE.VRMLLoader();loader.addEventListener('加载'，函数(事件){场景.添加(事件.内容)；});loader.load("3d/conjunto-carcaca.wrl");//渲染器renderer = new THREE.WebGLRenderer( { antialias: false } );renderer.setSize( window.innerWidth, window.innerHeight );container = document.createElement('div');document.body.appendChild(容器);container.appendChild(renderer.domElement);统计=新统计()；stats.domElement.style.position = '绝对';stats.domElement.style.top = '0px';container.appendChild(stats.domElement);//window.addEventListener('resize', onWindowResize, false );}函数 onWindowResize() {camera.aspect = window.innerWidth/window.innerHeight;相机.updateProjectionMatrix();renderer.setSize( window.innerWidth, window.innerHeight );control.handleResize();}函数动画(){requestAnimationFrame( 动画 );控制更新()；renderer.render(场景，相机)；stats.update();}

解决方案

如果你在 scene.add(event.content); 语句下添加这段代码，你场景中的所有对象都会转动红色.

scene.traverse(函数(对象){如果(对象实例THREE.Mesh){object.material.color.setHex(0xff0000);}});

I'm trying to use the Three.js with VRML (WRL) models. What I am wondering is that the model is loaded with variations of colors (colored). How can I load the model in solid color as the original file?

My example is: http://dev.logicarts.com.br/semapro/projeto-3d/teste-1.html

The code:

<div id="info">
    <a href="http://threejs.org" target="_blank">three.js</a> -
    vrml format loader test -
    <!--model from <a href="http://cs.iupui.edu/~aharris/webDesign/vrml/" target="_blank">VRML 2.0 Tutorial</a>,-->
    </div>

    <script src="js/three.min.js"></script>

    <script src="js/OrbitControls.js"></script>

    <script src="js/VRMLLoader.js"></script>

    <script src="js/Detector.js"></script>
    <script src="js/stats.min.js"></script>

    <script>

        if ( ! Detector.webgl ) Detector.addGetWebGLMessage();

        var container, stats;

        var camera, controls, scene, renderer;

        var cross;

        init();
        animate();

        function init() {

            camera = new THREE.PerspectiveCamera( 60, window.innerWidth / window.innerHeight, 0.01, 1e10 );
            camera.position.z = 6;

            controls = new THREE.OrbitControls( camera );

            controls.rotateSpeed = 5.0;
            controls.zoomSpeed = 5;

            controls.noZoom = false;
            controls.noPan = false;

            scene = new THREE.Scene();
            scene.add( camera );

            // light

            var dirLight = new THREE.DirectionalLight( 0xffffff );
            dirLight.position.set( 200, 200, 1000 ).normalize();

            camera.add( dirLight );
            camera.add( dirLight.target );

            var loader = new THREE.VRMLLoader();
            loader.addEventListener( 'load', function ( event ) {

                scene.add(event.content);

            } );
            loader.load( "3d/conjunto-carcaca.wrl" );

            // renderer

            renderer = new THREE.WebGLRenderer( { antialias: false } );
            renderer.setSize( window.innerWidth, window.innerHeight );

            container = document.createElement( 'div' );
            document.body.appendChild( container );
            container.appendChild( renderer.domElement );

            stats = new Stats();
            stats.domElement.style.position = 'absolute';
            stats.domElement.style.top = '0px';
            container.appendChild( stats.domElement );

            //

            window.addEventListener( 'resize', onWindowResize, false );

        }

        function onWindowResize() {

            camera.aspect = window.innerWidth / window.innerHeight;
            camera.updateProjectionMatrix();

            renderer.setSize( window.innerWidth, window.innerHeight );

            controls.handleResize();

        }

        function animate() {

            requestAnimationFrame( animate );

            controls.update();
            renderer.render( scene, camera );

            stats.update();

        }

    </script>

解决方案

If you add this code under the scene.add(event.content); statement, all the objects in your scene will turn red.

scene.traverse (function (object)
{
    if (object instanceof THREE.Mesh) {
        object.material.color.setHex( 0xff0000 );
    }
});
