//! This class Provides a polygon in 3D space. It is generally an approximate representation of a curve.
//! A Polygon3D is defined by a table of nodes. Each node is
//! a 3D point. If the polygon is closed, the point of closure is
//! repeated at the end of the table of nodes.
//! If the polygon is an approximate representation of a curve,
//! you can associate with each of its nodes the value of the
//! parameter of the corresponding point on the curve.
