deferred class Vector from Geom inherits Geometry from Geom
---Purpose : The abstract class Vector describes the common
-- behavior of vectors in 3D space.
-- The Geom package provides two concrete classes of
-- vectors: Geom_Direction (unit vector) and Geom_VectorWithMagnitude.
uses Ax1 from gp,
Ax2 from gp,
Pnt from gp,

raises ConstructionError from Standard,

is
Reverse (me : mutable);
---Purpose : Reverses the vector <me>.
Reversed (me) returns mutable like me
---Purpose :
-- Returns a copy of <me> reversed.
is static;
Angle (me; Other : Vector) returns Real
---Purpose : Computes the angular value, in radians, between this
-- vector and vector Other. The result is a value between 0 and Pi.
-- Exceptions
-- gp_VectorWithNullMagnitude if:
-- - the magnitude of this vector is less than or equal to
-- gp::Resolution(), or
-- - the magnitude of vector Other is less than or equal
-- to gp::Resolution().
raises VectorWithNullMagnitude;
AngleWithRef (me; Other , VRef : Vector) returns Real
---Purpose : Computes the angular value, in radians, between this
-- vector and vector Other. The result is a value
-- between -Pi and Pi. The vector VRef defines the
-- positive sense of rotation: the angular value is positive
-- if the cross product this ^ Other has the same
-- orientation as VRef (in relation to the plane defined
-- by this vector and vector Other). Otherwise, it is negative.
-- Exceptions
-- Standard_DomainError if this vector, vector Other
-- and vector VRef are coplanar, except if this vector
-- and vector Other are parallel.
-- gp_VectorWithNullMagnitude if the magnitude of
-- this vector, vector Other or vector VRef is less than
-- or equal to gp::Resolution().
raises DomainError,
VectorWithNullMagnitude;
Coord (me; X, Y, Z : out Real);
---Purpose : Returns the coordinates X, Y and Z of this vector.
Magnitude (me) returns Real
---Purpose : Returns the Magnitude of <me>.
is deferred;
SquareMagnitude (me) returns Real
---Purpose : Returns the square magnitude of <me>.
is deferred;
X (me) returns Real;
---Purpose : Returns the X coordinate of <me>.
Y (me) returns Real;
---Purpose : Returns the Y coordinate of <me>.
Z (me) returns Real;
---Purpose : Returns the Z coordinate of <me>.
Cross (me : mutable; Other : Vector)
---Purpose :
-- Computes the cross product between <me> and <Other>.
raises ConstructionError
---Purpose :
-- Raised if <me> is a "Direction" and if <me> and <Other>
-- are parallel because it is not possible to build a
-- "Direction" with null length.
is deferred;
Crossed (me; Other : Vector) returns mutable like me
---Purpose :
-- Computes the cross product between <me> and <Other>.
-- A new direction is returned.
raises ConstructionError
---Purpose :
-- Raised if <me> is a "Direction" and if the two vectors
-- are parallel because it is not possible to create a
-- "Direction" with null length.
is deferred;
CrossCross (me : mutable; V1, V2 : Vector)
---Purpose :
-- Computes the triple vector product <me> ^(V1 ^ V2).
raises ConstructionError
---Purpose :
-- Raised if <me> is a "Direction" and if V1 and V2 are parallel
-- or <me> and (V1 ^ V2) are parallel
is deferred;
CrossCrossed (me; V1, V2 : Vector) returns mutable like me
---Purpose :
-- Computes the triple vector product <me> ^(V1 ^ V2).
raises ConstructionError
---Purpose :
-- Raised if <me> is a direction and if V1 and V2 are
-- parallel or <me> and (V1 ^ V2) are parallel
is deferred;
Dot (me; Other : Vector) returns Real;
---Purpose : Computes the scalar product of this vector and vector Other.
DotCross (me; V1, V2 : Vector) returns Real;
---Purpose :
-- Computes the triple scalar product. Returns me . (V1 ^ V2)
Vec (me) returns Vec;
---Purpose : Converts this vector into a gp_Vec vector.
---C++: return const&

gpVec : Vec is protected;
