class Polygon3D from Poly inherits TShared from MMgt
|
|
|
|
---Purpose: 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.

|
|
|
Create(Nodes: Array1OfPnt from TColgp)
|
|
returns mutable Polygon3D from Poly;
|
|
---Purpose: onstructs a 3D polygon defined by the table of points, Nodes.
|
|
|
|
Create(Nodes: Array1OfPnt from TColgp;
|
|
Parameters: Array1OfReal from TColStd)
|
|
returns mutable Polygon3D from Poly;
|
|
---Purpose: 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.

Deflection(me) returns Real;
|
|
---Purpose: Returns the deflection of this polygon
|
|
Deflection(me : mutable; D : Real);
|
|
---Purpose: Sets the deflection of this polygon to D. See more on deflection in Poly_Polygon2D
|
|
|
|
NbNodes(me) returns Integer;
|
|
---Purpose: 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.

---C++: inline

|
Nodes(me) returns Array1OfPnt from TColgp
|
|
---Purpose: Returns the table of nodes for this polygon.
|
|
---C++: return const &
|
|
raises NullObject from Standard;
|
|
|
|
|
|
HasParameters(me) returns Boolean from Standard;
|
|
---Purpose: 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.
|
|
|
|
Parameters(me) returns Array1OfReal from TColStd
|
|
---Purpose: Returns true if parameters are associated with the nodes
|
|
-- in this polygon.
|
|
---C++: return const &
|
|
raises NullObject from Standard;
|
|
|
|
ChangeParameters(me) returns Array1OfReal from TColStd
|
|
---Purpose: 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.
