Poly_Polygon3D Class Reference

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.

 Poly_Polygon3D (const TColgp_Array1OfPnt &Nodes)
 onstructs a 3D polygon defined by the table of points, Nodes.

 Poly_Polygon3D (const TColgp_Array1OfPnt &Nodes, const TColStd_Array1OfReal &Parameters)
 Constructs a 3D polygon defined by
the table of points, Nodes, and the parallel table of
parameters, Parameters, where each value of the table
Parameters is the parameter of the corresponding point
on the curve approximated by the constructed polygon.
Warning
Both the Nodes and Parameters tables must have the
same bounds. This property is not checked at construction time.

Standard_Real Deflection () const
 Returns the deflection of this polygon

void Deflection (const Standard_Real D)
 Sets the deflection of this polygon to D. See more on deflection in Poly_Polygon2D

Standard_Integer NbNodes () const
 Returns the number of nodes in this polygon.
Note: If the polygon is closed, the point of closure is
repeated at the end of its table of nodes. Thus, on a closed
triangle the function NbNodes returns 4.

const TColgp_Array1OfPntNodes () const
 Returns the table of nodes for this polygon.

Standard_Boolean HasParameters () const
 Returns the table of the parameters associated with each node in this polygon.
HasParameters function checks if parameters are associated with the nodes of this polygon.

const TColStd_Array1OfRealParameters () const
 Returns true if parameters are associated with the nodes
in this polygon.

TColStd_Array1OfRealChangeParameters () const
 Returns the table of the parameters associated with each node in this polygon.
ChangeParameters function returnes the array as shared. Therefore if the table is selected by
reference you can, by simply modifying it, directly modify
the data structure of this polygon.
