Function rgmsh::interface::occ::add_torus

pub unsafe extern "C" fn add_torus(
    x: f64, 
    y: f64, 
    z: f64, 
    r1: f64, 
    r2: f64, 
    tag: i32,

) -> i32

Add a torus, defined by its center (x, y, z) and its 2 radii r and r2. If tag is positive, set the tag explicitly; otherwise a new tag is selected automatically. The optional argument angle defines the angular opening (from 0 to 2*Pi). Return the tag of the wedge.
