three.js BoundingBoxHelper that excludes diagonal lines

When I look at my BoundingBox, I see triangles inside the box that I don't want to show. How can I remove those lines? Thanks.

    var bbox = new THREE.BoundingBoxHelper(object3d, new THREE.Color(0xFF9900));
    bbox.visible = false;
    bbox.name = "BBOX"
    bbox.update();

    object3d.children[0] = bbox;

    scene.add(bbox);

Answer №1

UPDATE: The old method with BounxingBoxHelper is no longer supported. Follow this new approach instead:

// create box helper
boxHelper = new THREE.BoxHelper( parent );
boxHelper.material.color.set( 0xffffff );
scene.add( boxHelper );

Make sure to include this in your render loop:

boxHelper.update();

Using three.js version r.85

Answer №2

As of the latest release, three.js r72, you can now use the THREE.BoxHelper class to easily create wireframe boxes without diagonals.

var helper = new THREE.BoxHelper( object );

scene.add( helper );

Answer №3

To access the dimensions of your environment, utilize a BoundingBox and transfer them to a BoxGeometry along with a wireframe material. The BoxGeometry lacks the presence of triangles within.
