deferred class Geometry from Geom2d inherits TShared from MMgt
|
|
|
|
--- Purpose :
|
|
-- The general abstract class Geometry in 2D space describes
|
|
-- the common behaviour of all the geometric entities.
|
|
--
|
|
-- All the objects derived from this class can be move with a
|
|
-- geometric transformation. Only the transformations which
|
|
-- doesn't modify the nature of the geometry are available in
|
|
-- this package.
|
|
-- The method Transform which defines a general transformation
|
|
-- is deferred. The other specifics transformations used the
|
|
-- method Transform.
|
|
-- All the following transformations modify the object itself.
|
|
-- Warning
|
|
-- Only transformations which do not modify the nature
|
|
-- of the geometry can be applied to Geom2d objects:
|
|
-- this is the case with translations, rotations,
|
|
-- symmetries and scales; this is also the case with
|
|
-- gp_Trsf2d composite transformations which are
|
|
-- used to define the geometric transformations applied
|
|
-- using the Transform or Transformed functions.
|
|
-- Note: Geometry defines the "prototype" of the
|
|
-- abstract method Transform which is defined for each
|
|
-- concrete type of derived object. All other
|
|
-- transformations are implemented using the Transform method.

Mirror (me : mutable; P : Pnt2d)
|
|
--- Purpose : Performs the symmetrical transformation of a Geometry
|
|
-- with respect to the point P which is the center of the
|
|
-- symmetry and assigns the result to this geometric object.
|
|

Mirror (me : mutable; A : Ax2d)
|
|
--- Purpose : Performs the symmetrical transformation of a Geometry
|
|
-- with respect to an axis placement which is the axis of the symmetry.
|
|
is static;
|
|
|
|
|
|
|
|
Rotate (me : mutable; P : Pnt2d; Ang : Real)
|
|
--- Purpose : Rotates a Geometry. P is the center of the rotation.
|
|
-- Ang is the angular value of the rotation in radians.
|
|
is static;
|
|
|
|
|
|
Scale (me : mutable; P : Pnt2d; S : Real)
|
|
--- Purpose : Scales a Geometry. S is the scaling value.
|
|
is static;
|
|
|
|
|
|
Translate (me : mutable; V : Vec2d)
|
|
--- Purpose : Translates a Geometry. V is the vector of the tanslation.
|
|
is static;
|
|
|
|
Translate (me : mutable; P1, P2 : Pnt2d)
|
|
--- Purpose : Translates a Geometry from the point P1 to the point P2.
|
|
is static;
|
|
|
|
Transform (me : mutable; T : Trsf2d)
|
|
--- Purpose : Transformation of a geometric object. This tansformation
|
|
-- can be a translation, a rotation, a symmetry, a scaling
|
|
-- or a complex transformation obtained by combination of
|
|
-- the previous elementaries transformations.
|
|
-- (see class Transformation of the package Geom2d).
|
|
is deferred;
|
|
|
|
|
|
|
|
|
|
--- Purpose : The following transformations have the same properties
|
|
-- as the previous ones but they don't modified the object
|
|
-- itself. A copy of the object is returned.
