|
SquareMagnitude (me) returns Real;
|
|
--- Purpose : returns 1.0
|
|
|
|
|
|
Crossed (me; Other : Vector) returns Real;
|
|
--- Purpose : Computes the cross product between <me> and <Other>.

|
Transform (me : mutable; T : Trsf2d);
|
|
|
|
---Purpose: Applies the transformation T to this unit vector, then normalizes it.
|
|
|
|
|
|
Copy (me) returns mutable like me;
|
|
---Purpose: Creates a new object which is a copy of this unit vector.
