//! This class provides a polygon in 3D space, based on the triangulation
//! of a surface. It may be the approximate representation of a
//! curve on the surface, or more generally the shape.
//! A PolygonOnTriangulation is defined by a table of
//! nodes. Each node is an index in the table of nodes specific
//! to a triangulation, and represents a point on the surface. If
//! the polygon is closed, the index of the point of closure is
//! repeated at the end of the table of nodes.
//! If the polygon is an approximate representation of a curve
//! on a surface, you can associate with each of its nodes the
//! value of the parameter of the corresponding point on the
//! curve.represents a 3d Polygon
