Method Detail

createNewInstance

public Vector2D_F32 createNewInstance()

Description copied from class: GeoTuple

Creates a new tuple instance of the same type.

Specified by:

createNewInstance in class GeoTuple<Vector2D_F32>

Returns:

new tuple instance.

set

public void set(Vector2D_F32 orig)

copy

public Vector2D_F32 copy()

Description copied from class: GeoTuple_F32

Generic copy routine. It is recommended that this be overridden with a faster implementation.

Overrides:

copy in class GeoTuple_F32<Vector2D_F32>

Returns:

An exact copy of this GeoTuple.

normalize

public void normalize()

minus

public void minus(Point2D_F32 a,
                  Point2D_F32 b)

In-place minus operation. this = a - b.

Parameters:

a - Point

b - Point

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

dot

public float dot(Vector2D_F32 a)

Dot product between this and 'a' = this.x * a.x + this.y * a.y

Parameters:

a - A vector

Returns:

dot product.

acute

public float acute(Vector2D_F32 a)

Returns the acute angle between the two vectors. Computed using the dot product.

Parameters:

a - Vector

Returns:

Acute angle in radians between 'this' and 'a'.
