javascript - Threejs Canvas 不会调整到标签 div

Question

我已将我的标签 Canvas 放入一个 div 中，用于 Bootstrap 布局，但 Canvas 比 div 容器大，并且它不会自行调整为 div 大小。我不明白这是什么原因。现场示例:http://www.felpone.netsons.org/web-threejs/

<div class="row">


<div class="col-sm-8" style="background-color:lavenderblush;" id="ThreeJS" data-toggle="context" data-target="#context-menu"></div>



<div class="col-sm-4" style="background-color:lavender;">.col-sm-4</div>



</div>



#ThreeJS canvas {

position: static!important;
padding: 1px!important;
margin: 1px!important;
background-color: rgba(188, 188, 188, 0.44)!important;

 }

这是我的 threejs 代码:

var SCREEN_WIDTH = window.innerWidth-5, SCREEN_HEIGHT = window.innerHeight-5;

    var VIEW_ANGLE = 45, ASPECT = SCREEN_WIDTH / SCREEN_HEIGHT, NEAR = 0.01, FAR = 20000;
    camera = new THREE.PerspectiveCamera( VIEW_ANGLE, ASPECT, NEAR, FAR);
    var r = 4, phi = Math.PI/4, theta = Math.PI/4;
    camera.position.set(r*Math.cos(phi)*Math.sin(theta),r*Math.sin(phi), r*Math.cos(phi)*Math.cos(theta));

    // RENDERER
    if ( Detector.webgl )
            renderer = new THREE.WebGLRenderer( {antialias:true} );
    else
            renderer = new THREE.CanvasRenderer(); 
    renderer.setSize(SCREEN_WIDTH, SCREEN_HEIGHT);
    renderer.autoClear = false;

    // CONTAINER
    container = document.getElementById( 'ThreeJS' );
    container.appendChild( renderer.domElement );

    // EVENTS
    THREEx.WindowResize(renderer, camera);
    THREEx.FullScreen.bindKey({ charCode : 'm'.charCodeAt(0) });

    // CONTROLS
    controls = new THREE.OrbitControls( camera, renderer.domElement );
    controls.addEventListener( 'change', render );
    controls.target = new THREE.Vector3(0, 0, 0);

Answer 1

您将渲染器大小(= Canvas )设置为 (window.innerWidth-5)/(window.innerHeight-5)，几乎整页。首先在SCREEN_WIDTH和SCREEN_HEIGHT之前定义container，然后将它们替换为:

var containerStyle = getComputedStyle(container,null);
var SCREEN_HEIGHT = parseInt(containerStyle.getPropertyValue('height')),
    SCREEN_WIDTH = parseInt(containerStyle.getPropertyValue('width'));

在 THREEx.WindowResize 函数中相同:找到定义高度和宽度的位置，并将它们替换为这些值。
