//! adds methods to  draw 3D Curves  and  Curves on 3D
//! Surfaces.
//!
//! The classes Curve Curve2d and Surface are drawable
//! and  can be  used  to  draw a   single  curve from
//! packages Geom or Geom2d or a surface from Geom.
//!
//! The Triangulation and Polygon from the package Poly are also supported.
