- <p class="desc">Helper object to visualize a [page:Box3].</p>
- <h2>Code Example</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>
- <h2>Constructor</h2>
- <h3>[name]( [param:Box3 box], [param:Color color] )</h3>
- <p>
- [page:Box3 box] -- the Box3 to show.<br />
- [page:Color color] -- (optional) the box's color. Default is 0xffff00.<br /><br />
- Creates a new wireframe box that represents the passed Box3.
- </p>
- <h2>Properties</h2>
- <p>See the base [page:LineSegments] class for common properties.</p>
- <h3>[property:Box3 box]</h3>
- <p>The Box3 being visualized.</p>
- <h2>Methods</h2>
- <p>See the base [page:LineSegments] class for common methods.</p>
- <h3>[method:undefined updateMatrixWorld]( [param:Boolean force] )</h3>
- <p>
- 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.
- </p>
- <h3>[method:undefined dispose]()</h3>
- <p>
- Frees the GPU-related resources allocated by this instance. Call this
- method whenever this instance is no longer used in your app.
