Detailed Description

Describes a coordinate system in a plane (2D space). A coordinate system is defined by: - its origin (also referred to as its "Location point"), and - two orthogonal unit vectors, respectively, called the "X Direction" and the "Y Direction". A gp_Ax22d may be right-handed ("direct sense") or left-handed ("inverse" or "indirect sense"). You use a gp_Ax22d to: - describe 2D geometric entities, in particular to position them. The local coordinate system of a geometric entity serves for the same purpose as the STEP function "axis placement two axes", or - define geometric transformations. Note: we refer to the "X Axis" and "Y Axis" as the axes having: - the origin of the coordinate system as their origin, and - the unit vectors "X Direction" and "Y Direction", respectively, as their unit vectors.

Constructor & Destructor Documentation

GAx22d.GAx22d

(

)

Creates an object representing the reference co-ordinate system (OXY).

GAx22d.GAx22d	(	GPnt2d	P,
		GDir2d	Vx,
		GDir2d	Vy
	)

Creates a coordinate system with origin P and where: - Vx is the "X Direction", and - the "Y Direction" is orthogonal to Vx and oriented so that the cross products Vx^"Y Direction" and Vx^Vy have the same sign. Raises ConstructionError if Vx and Vy are parallel (same or opposite orientation).

GAx22d.GAx22d	(	GPnt2d	P,
		GDir2d	V,
		boolean	Sense
	)

Creates - a coordinate system with origin P and "X Direction" V, which is: - right-handed if Sense is true (default value), or - left-handed if Sense is false

GAx22d.GAx22d	(	GPnt2d	P,
		GDir2d	V
	)

Creates - a coordinate system with origin P and "X Direction" V, which is: - right-handed if Sense is true (default value), or - left-handed if Sense is false

GAx22d.GAx22d	(	GAx2d	A,
		boolean	Sense
	)

Creates - a coordinate system where its origin is the origin of A and its "X Direction" is the unit vector of A, which is: - right-handed if Sense is true (default value), or - left-handed if Sense is false.

GAx22d.GAx22d

(

GAx2d

A

)

Creates - a coordinate system where its origin is the origin of A and its "X Direction" is the unit vector of A, which is: - right-handed if Sense is true (default value), or - left-handed if Sense is false.

Member Function Documentation

GPnt2d GAx22d.Location

(

)

Returns the "Location" point (origin) of <me>.

GAx22d GAx22d.Mirrored

(

GPnt2d

P

)

Performs the symmetrical transformation of an axis placement with respect to the point P which is the center of the symmetry. Warnings : The main direction of the axis placement is not changed. The "XDirection" and the "YDirection" are reversed. So the axis placement stay right handed.

GAx22d GAx22d.Mirrored

(

GAx2d

A

)

Performs the symmetrical transformation of an axis placement with respect to an axis placement which is the axis of the symmetry. The transformation is performed on the "Location" point, on the "XDirection" and "YDirection". The resulting main "Direction" is the cross product between the "XDirection" and the "YDirection" after transformation.

GAx22d GAx22d.Rotated	(	GPnt2d	P,
		double	Ang
	)

Rotates an axis placement. <A1> is the axis of the rotation . Ang is the angular value of the rotation in radians.

GAx22d GAx22d.Scaled	(	GPnt2d	P,
		double	S
	)

Applies a scaling transformation on the axis placement. The "Location" point of the axisplacement is modified. Warnings : If the scale <S> is negative : . the main direction of the axis placement is not changed. . The "XDirection" and the "YDirection" are reversed. So the axis placement stay right handed.

void GAx22d.SetAxis

(

GAx22d

A1

)

Assigns the origin and the two unit vectors of the coordinate system A1 to this coordinate system.

void GAx22d.SetLocation

(

GPnt2d

P

)

Changes the "Location" point (origin) of <me>.

void GAx22d.SetXAxis

(

GAx2d

A1

)

Changes the XAxis and YAxis ("Location" point and "Direction") of <me>. The "YDirection" is recomputed in the same sense as before.

void GAx22d.SetXDirection

(

GDir2d

Vx

)

Assigns Vx to the "X Direction" of this coordinate system. The other unit vector of this coordinate system is recomputed, normal to Vx , without modifying the orientation (right-handed or left-handed) of this coordinate system.

void GAx22d.SetYAxis

(

GAx2d

A1

)

Changes the XAxis and YAxis ("Location" point and "Direction") of <me>. The "XDirection" is recomputed in the same sense as before.

void GAx22d.SetYDirection

(

GDir2d

Vy

)

Assignsr Vy to the "Y Direction" of this coordinate system. The other unit vector of this coordinate system is recomputed, normal to Vy, without modifying the orientation (right-handed or left-handed) of this coordinate system.

GAx22d GAx22d.Transformed

(

GTrsf2d

T

)

Transforms an axis placement with a Trsf. The "Location" point, the "XDirection" and the "YDirection" are transformed with T. The resulting main "Direction" of <me> is the cross product between the "XDirection" and the "YDirection" after transformation.

GAx22d GAx22d.Translated

(

GVec2d

V

)

Translates an axis plaxement in the direction of the vector <V>. The magnitude of the translation is the vector's magnitude.

GAx22d GAx22d.Translated	(	GPnt2d	P1,
		GPnt2d	P2
	)

Translates an axis placement from the point <P1> to the point <P2>.

GAx2d GAx22d.XAxis

(

)

Returns an axis, for which - the origin is that of this coordinate system, and - the unit vector is either the "X Direction" of this coordinate system. Note: the result is the "X Axis" of this coordinate system.

(

)

Returns the "XDirection" of <me>.

GAx2d GAx22d.YAxis

(

)

Returns an axis, for which - the origin is that of this coordinate system, and - the unit vector is either the "Y Direction" of this coordinate system. Note: the result is the "Y Axis" of this coordinate system.
