[page:Object3D] →
<h1>组（[name]）</h1>
<p class="desc">
它几乎和[page:Object3D Object3D]是相同的，其目的是使得组中对象在语法上的结构更加清晰。
</p>
<h2>代码示例</h2>
<code>
const geometry = new THREE.BoxGeometry( 1, 1, 1 );
const material = new THREE.MeshBasicMaterial( {color: 0x00ff00} );
const cubeA = new THREE.Mesh( geometry, material );
cubeA.position.set( 100, 100, 0 );
const cubeB = new THREE.Mesh( geometry, material );
cubeB.position.set( -100, -100, 0 );
//create a group and add the two cubes
//These cubes can now be rotated / scaled etc as a group
const group = new THREE.Group();
group.add( cubeA );
group.add( cubeB );
scene.add( group );
</code>
<h2>构造器</h2>
