										<h2>代码示例</h2>
							 | 
						|
								
							 | 
						|
										<code>
							 | 
						|
										const box = new THREE.Box3();
							 | 
						|
										box.setFromCenterAndSize( new THREE.Vector3( 1, 1, 1 ), new THREE.Vector3( 2, 1, 3 ) );
							 | 
						|
								
							 | 
						|
										const helper = new THREE.Box3Helper( box, 0xffff00 );
							 | 
						|
										scene.add( helper );
							 | 
						|
										</code>

										[page:Box3 box]  -- 被模拟的3维包围盒.<br />
							 | 
						|
										[page:Color color] --  (可选的) 线框盒子的颜色. 默认为 0xffff00.<br /><br />
							 | 
						|
								
							 | 
						|
										创建一个新的线框盒子用以表示指定的3维包围盒.
