Returns the bbox of a geometry, or a component of the bbox.


## Description

It takes 1, 2 or 3 arguments.

`bbox(input_index_or_node_path, bbox_vector, vector_component)`

- `input_index_or_node_path` is a number or a string
- `bbox_vector` is a string, either 'min' or 'max'
- `vector_component` is a string, either 'x', 'y' or 'z'

## Usage

- `bbox(0)` - returns the bbox of the input node, as a THREE.Box3
- `bbox('/geo1/box')` - returns the bbox of the node /geo1/box, as a THREE.Box3
- `bbox('/geo1/box', 'min')` - returns the min vector of the bbox, as a THREE.Vector3
- `bbox('/geo1/box', 'min', 'x')` - returns the x component of min vector of the bbox, as a number
