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. More...

Public Member Functions  
Poly_Polygon3D (const TColgp_Array1OfPnt &Nodes)  
onstructs a 3D polygon defined by the table of points, Nodes. More...  
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. More...  
Standard_Real  Deflection () const 
Returns the deflection of this polygon. More...  
void  Deflection (const Standard_Real D) 
Sets the deflection of this polygon to D. See more on deflection in Poly_Polygon2D. More...  
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. More...  
const TColgp_Array1OfPnt &  Nodes () const 
Returns the table of nodes for this polygon. More...  
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. More...  
const TColStd_Array1OfReal &  Parameters () const 
Returns true if parameters are associated with the nodes in this polygon. More...  
TColStd_Array1OfReal &  ChangeParameters () 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. More...
