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...

Detailed Description

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.

Constructor & Destructor Documentation

◆ Poly_Polygon3D() [1/3]

Poly_Polygon3D::Poly_Polygon3D	(	const Standard_Integer	theNbNodes,
		const Standard_Boolean	theHasParams
	)

◆ Poly_Polygon3D() [3/3]

Poly_Polygon3D::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.

Member Function Documentation

◆ ChangeNodes()

TColgp_Array1OfPnt& Poly_Polygon3D::ChangeNodes ( )

inline

Returns the table of nodes for this polygon.

◆ ChangeParameters()

TColStd_Array1OfReal& Poly_Polygon3D::ChangeParameters ( ) const

inline

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.

◆ Copy()

virtual Handle< Poly_Polygon3D > Poly_Polygon3D::Copy ( ) const

virtual

Creates a copy of current polygon.

◆ Deflection() [1/2]

Standard_Real Poly_Polygon3D::Deflection ( ) const

inline

Returns the deflection of this polygon.

◆ Deflection() [2/2]

void Poly_Polygon3D::Deflection ( const Standard_Real theDefl )

inline

Sets the deflection of this polygon. See more on deflection in Poly_Polygon2D.

◆ DumpJson()

virtual void Poly_Polygon3D::DumpJson	(	Standard_OStream &	theOStream,
		Standard_Integer	theDepth = `-1`
	)		const

virtual

Dumps the content of me into the stream.

◆ HasParameters()

Standard_Boolean Poly_Polygon3D::HasParameters ( ) const

inline

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.

◆ NbNodes()

Standard_Integer Poly_Polygon3D::NbNodes ( ) const

inline

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.

◆ Nodes()

const TColgp_Array1OfPnt& Poly_Polygon3D::Nodes ( ) const

inline

Returns the table of nodes for this polygon.

◆ Parameters()

const TColStd_Array1OfReal& Poly_Polygon3D::Parameters ( ) const

inline

Returns true if parameters are associated with the nodes in this polygon.
