b - Vector

cross

public Vector3D_F32 cross(Vector3D_F32 b)

createNewInstance

public Vector3D_F32 createNewInstance()

Description copied from class: GeoTuple

Creates a new tuple instance of the same type.

Specified by:

createNewInstance in class GeoTuple<Vector3D_F32>

Returns:

new tuple instance.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

normalize

public void normalize()

dot

public float dot(Vector3D_F32 a)

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

Parameters:

a - A vector

Returns:

dot product.

acute

public float acute(Vector3D_F32 a)

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

Parameters:
