You should reset the result properties to be an 'empty' bounding box. For example, what if I do this:
`var obb = ObjectOrientedBoundingBox.fromPoints(undefined, result);`
or, more likely,
`var obb = ObjectOrientedBoundingBox.fromPoints([], result);`
where `result` is a valid bounding box. `obb` and `result` should both be 'empty'.
