[name]

Helper object to visualize a [page:Box3].

Code Example


		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 );

Constructor

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

[page:Box3 box] -- the Box3 to show.
[page:Color color] -- (optional) the box's color. Default is 0xffff00.

Creates a new wireframe box that represents the passed Box3.

Properties

See the base [page:LineSegments] class for common properties.

[property:Box3 box]

The Box3 being visualized.

Methods

See the base [page:LineSegments] class for common methods.

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

This overrides the method in the base [page:Object3D] class so that it also updates the wireframe box to the extent of the [page:Box3Helper.box .box] property.

[method:undefined dispose]()

Frees the GPU-related resources allocated by this instance. Call this method whenever this instance is no longer used in your app.
