deferred class Vector from Geom2d inherits Geometry from Geom2d
|
|
|
|
--- Purpose : The abstract class Vector describes the common
|
|
-- behavior of vectors in 2D space.
|
|
-- The Geom2d package provides two concrete
|
|
-- classes of vectors: Geom2d_Direction (unit vector)
|
|
-- and Geom2d_VectorWithMagnitude.
|
|
|
|
uses Ax2d from gp,

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 -Pi and Pi. The orientation is from this
|
|
-- vector to vector Other.
|
|
-- Raises VectorWithNullMagnitude if one of the two vectors is a vector with
|
|
-- null magnitude because the angular value is indefinite.

--- Purpose : Returns the Magnitude of <me>.

|
|
--- Purpose : Returns the X coordinate of <me>.
