Optional makeEmpty in THREE.Box3

[sunag]

Hi.
This solve problems with to collect parallel objects(no relationship) in THREE.Box3.
Otherwise would have to create a Box3 for each object or add all in an single Object3D

var meshes = [mesh1, mesh2, ..[n].. ]
var bbox = new THREE.Box3();

for(var i = 0; i < meshes.length; i++) {
	bbox.setFromObject( meshes[i], false ); // false = not call `makeEmpty`
}

Instead, why not add the method

Box3.expandByObject( object )

and rewrite setFromObject() to call the new method.

and rewrite setFromObject() to call the new method.

@WestLangley added!

[WestLangley]

Why did you remove makeEmpty() here?

[sunag]

Sry my distraction... I will add.

I'm not 100% sure about the consistency of this change. Box3 .setFromObject() will be the only method that allows an optional empty operation. But what about the other .setFrom*() methods?

[WestLangley]

@Mugen87 We have expandBy*() and setFrom*() now. See the coments above, and ignore the post title.

I see...

Need to update the docs for the new .expandByObject() method.
