Redundant keyword 'mutable' removed in CDL files. In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed. Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.

class Polygon2D from Poly inherits TShared from MMgt
|
|
|
|
---Purpose: Provides a polygon in 2D space (for example, in the
|
|
-- parametric space of a surface). It is generally an
|
|
-- approximate representation of a curve.
|
|
-- A Polygon2D is defined by a table of nodes. Each node is
|
|
-- a 2D point. If the polygon is closed, the point of closure is
|
|
-- repeated at the end of the table of nodes.

returns Polygon2D from Poly;
|
|
---Purpose: Constructs a 2D polygon defined by the table of points, <Nodes>.
|
|
|
|
Deflection(me) returns Real;
|
|
---Purpose: Returns the deflection of this polygon.
|
|
-- Deflection is used in cases where the polygon is an
|
|
-- approximate representation of a curve. Deflection
|
|
-- represents the maximum distance permitted between any
|
|
-- point on the curve and the corresponding point on the polygon.
|
|
-- By default the deflection value is equal to 0. An algorithm
|
|
-- using this 2D polygon with a deflection value equal to 0
|
|
-- considers that it is working with a true polygon and not with
|
|
-- an approximate representation of a curve. The Deflection
|
|
-- function is used to modify the deflection value of this polygon.
|
|
-- The deflection value can be used by any algorithm working with 2D polygons.
|
|
-- For example:
|
|
-- - An algorithm may use a unique deflection value for all
|
|
-- its polygons. In this case it is not necessary to use the
|
|
-- Deflection function.
|
|
-- - Or an algorithm may want to attach a different
|
|
-- deflection to each polygon. In this case, the Deflection
|
|
-- function is used to set a value on each polygon, and
|
|
-- later to fetch the value.
|
|
|
|
Deflection(me : mutable; D : Real);
|
|
---Purpose: Sets the deflection of this polygon to D
|
|
|
|
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.
