    It is used for storing vertices, faces and morphometric data
    (curvature) of a hemisphere mesh.

    Parameters
    ----------
    subject_id : string
        Name of subject
    hemi : {'lh', 'rh'}
        Which hemisphere to load
    surf : string
        Name of the surface to load (eg. inflated, orig ...).
    subjects_dir : str | None
        If not None, this directory will be used as the subjects directory
        instead of the value set using the SUBJECTS_DIR environment variable.
    offset : float | None
        If 0.0, the surface will be offset such that the medial
        wall is aligned with the origin. If None, no offset will
        be applied. If != 0.0, an additional offset will be used.
    units : str
        Can be 'm' or 'mm' (default).
    x_dir : ndarray | None
        The x direction to use for offset alignment.

    Attributes
    ----------
    bin_curv : numpy.ndarray
        Curvature values stored as non-negative integers.
    coords : numpy.ndarray
        nvtx x 3 array of vertex (x, y, z) coordinates.
    curv : numpy.ndarray
        Vector representation of surface morpometry (curvature) values as
        loaded from a file.
    grey_curv : numpy.ndarray
        Normalized morphometry (curvature) data, used in order to get
        a gray cortex.
    faces : numpy.ndarray
        nfaces x 3 array of defining mesh triangles.
    hemi : {'lh', 'rh'}
        Which hemisphere to load.
    nn : numpy.ndarray
        Vertex normals for a triangulated surface.
    offset : float | None
        If float, align inside edge of each hemisphere to center + offset.
        If None, do not change coordinates (default).
    subject_id : string
        Name of subject.
    surf : string
        Name of the surface to load (eg. inflated, orig ...).
    units : str
        Can be 'm' or 'mm' (default).
