        Parameters
        ----------
        min_pt : :obj:`numpy.ndarray` of float
            The minimum x, y, and (optionally) z points.

        max_pt : :obj:`numpy.ndarray` of float
            The maximum x, y, and (optionally) z points.

        frame : :obj:`str`

        Raises
        ------
        ValueError
            If max_pt is not strictly larger than min_pt in all dims.
