Question

Three.js版本： 82

我在这里看这个例子：https://threejs.org/examples/#webgl_helpers

请注意，模型周围有黄色框。我使用的是79版，并使用 THREE.EdgesHelper 来勾画我在Blender中制作的3D对象，但是THREE.EdgesHelper被 THREE.EdgesGeometry 取代。我想看一个这样的例子，我能找到的唯一一个链接在上面。

我潜入行和 BoxHelper 对象，但我没有注意到任何可以让我摆脱那些黄色框的东西。

JSFiddle：https://jsfiddle.net/4nbjvmpe/

以下是JSFiddle的代码：

HTML

<script src="https://threejs.org/build/three.min.js"></script>
<script src="https://threejs.org/examples/js/controls/OrbitControls.js"></script>

CSS

body {
    background-color: #000;
    margin: 0px;
    overflow: hidden;
}

的JavaScript

var mesh, renderer, scene, camera, controls;

init();
animate();

function init() {

    // renderer
    renderer = new THREE.WebGLRenderer();
    renderer.setSize( window.innerWidth, window.innerHeight );
    document.body.appendChild( renderer.domElement );

    // scene
    scene = new THREE.Scene();

    // camera
    camera = new THREE.PerspectiveCamera( 40, window.innerWidth / window.innerHeight, 1, 10000 );
    camera.position.set( 20, 20, 20 );

    // controls
    controls = new THREE.OrbitControls( camera );

    // ambient
    scene.add( new THREE.AmbientLight( 0x222222 ) );

    // light
    var light = new THREE.DirectionalLight( 0xffffff, 1 );
    light.position.set( 20, 20, 0 );
    scene.add( light );

    // geometry
    var geometry = new THREE.SphereGeometry( 5, 12, 8 );

    // material
    var material = new THREE.MeshPhongMaterial( {
        color: 0x00ffff, 
        shading: THREE.FlatShading,
        transparent: true,
        opacity: 0.7,
    } );

    // mesh
    mesh = new THREE.Mesh( geometry, material );
    scene.add( mesh );

    // CUSTOM
    // This is where I create the outline mesh.
    var group = new THREE.Group();
    scene.add( group );
    group.updateMatrixWorld(true);
    var edges = new THREE.EdgesGeometry(geometry);
    var line = new THREE.LineSegments(edges);
    group.add(line);
    line.material.depthTest = true;
    line.material.opacity = 0.25;
    line.material.transparent = false;
    this.outlineMesh = new THREE.BoxHelper(line);
    scene.add(this.outlineMesh);
}

function animate() {
    requestAnimationFrame( animate );
    renderer.render( scene, camera );
}

Answer 1

只需评论this.outlineMesh = new THREE.BoxHelper(line);和scene.add(this.outlineMesh);即可。你会得到你想要的东西。
