[name]

模拟3维包围盒 [page:Box3] 的辅助对象.

代码示例


		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 );

构造函数

[name]( [param:Box3 box], [param:Color color] )

[page:Box3 box] -- 被模拟的3维包围盒.
[page:Color color] -- (可选的) 线框盒子的颜色. 默认为 0xffff00.

创建一个新的线框盒子用以表示指定的3维包围盒.

属性

请到基类 [page:LineSegments] 页面查看公共属性.

[property:Box3 box]

被模拟的3维包围盒.

方法

请到基类 [page:LineSegments] 页面查看公共方法.

[method:undefined updateMatrixWorld]( [param:Boolean force] )

重写基类 [page:Object3D] 的该方法以便于同时更新线框辅助对象与 [page:Box3Helper.box .box] 属性保持一致.
