Poly_PolygonOnTriangulation Class Reference

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

Public Member Functions

Standard_EXPORT Poly_PolygonOnTriangulation (const TColStd_Array1OfInteger &Nodes)
 Constructs a 3D polygon on the triangulation of a shape,
defined by the table of nodes, <nodes>.
.
Standard_EXPORT Poly_PolygonOnTriangulation (const TColStd_Array1OfInteger &Nodes, const TColStd_Array1OfReal &Parameters)
 Constructs a 3D polygon on the triangulation of a shape, defined by:
- the table of nodes, Nodes, and the table of parameters, <parameters>.
where:
- a node value is an index in the table of nodes specific
to an existing triangulation of a shape
- and a parameter value is the value of the parameter of
the corresponding point on the curve approximated by
the constructed polygon.
Warning
The tables Nodes and Parameters must be the same size.
This property is not checked at construction time.
.
Standard_EXPORT Standard_Real Deflection () const
 Returns the deflection of this polygon
.
Standard_EXPORT void Deflection (const Standard_Real D)
 Sets the deflection of this polygon to D.
See more on deflection in Poly_Polygones2D.
.
Standard_Integer NbNodes () const
 Returns the number of nodes for 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.
.
Standard_EXPORT const TColStd_Array1OfIntegerNodes () const
 Returns the table of nodes for this polygon. A node value
is an index in the table of nodes specific to an existing
triangulation of a shape.
.
Standard_EXPORT Standard_Boolean HasParameters () const
 Returns true if parameters are associated with the nodes in this polygon.
.
Standard_EXPORT Handle_TColStd_HArray1OfReal Parameters () const
 Returns the table of the parameters associated with each node in this polygon.
Warning
Use the function HasParameters to check if parameters
are associated with the nodes in this polygon.
