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.
