Detailed Description¶

It can be used to contain a 2d vector as most of the methods for points have a default z value assigned to 0.

__init__()¶

__init__(pini, pfin)

Parameters:

pini – GKPoint
pfin – GKPoint

Constructs a 3D vector using an initial and end points that will be used to calculate its coordinates.

__init__(ax, ay[, az=0.0])

Parameters:

ax – float
ay – float
az – float

Constructs a 3D vector setting the x, y and z coordinates.

angle(v2)¶

Parameters:: v2 – GKVector
Return type:: float

It returns the smallest angle between “this” and “v2” vectors in radians

angleWithTheHorizontal()¶

Return type:: float

It returns the angle this vector makes with the horizontal in radians between - GKPI and GKPI. Note: The horizontal is interpreted as the vector (1.0, 0.0)

crossProduct(v2)¶

Parameters:: v2 – GKVector
Return type:: GKVector

Returns the resulting vector of calculating the cross (vector) product between this vector and v2

dotProduct(v2)¶

Parameters:: v2 – GKVector
Return type:: float

Returns the dot (scalar) product between to vectors

fullAngle(v2)¶

Parameters:: v2 – GKVector
Return type:: float

It returns the angle between “this” and “v2” vectors in radians (0 - 2PI)

getLength()¶

Return type:: float

Gets the vector length calculated using the points or coordinates defined for the vector.

getX()¶

Return type:: float

Gets the x coordinate of this vector.

getY()¶

Return type:: float

Gets the y coordinate of this vector.

getZ()¶

Return type:: float

Gets the z coordinate of this vector.

normalize()¶

Normalizes this vector changing its length to 1.0 meter and normalizing the x,y and z coordinates

normalized()¶

Return type:: GKVector

Returns a normalized version of this vector

__mul__(d)¶

Parameters:: d – float
Return type:: GKVector

__imul__(d)¶

Parameters:: d – float
Return type:: GKVector

__add__(_point)¶

Parameters:: _point – GKPoint
Return type:: GKVector

__add__(_vector)

Parameters:: _vector – GKVector
Return type:: GKVector

__iadd__(rhs)¶

Parameters:: rhs – GKVector
Return type:: GKVector

__sub__()¶

Return type:: GKVector

Devuelve un objeto diferente.

__sub__(_point)

Parameters:: _point – GKPoint
Return type:: GKVector

__sub__(_vector)

Parameters:: _vector – GKVector
Return type:: GKVector

__isub__(rhs)¶

Parameters:: rhs – GKVector
Return type:: GKVector

rotate(center, angle)¶

Parameters:

center – GKPoint
angle – float

Rotates the vector an angle ‘angle’ in radians taking ‘center’ as the center of rotation

set(pini, pfin)¶

Parameters:

pini – GKPoint
pfin – GKPoint

Sets the origin and destination point of this vector, used to indicate the vector’s direction.

set(ax, ay[, az=0.0])

Parameters:

ax – float
ay – float
az – float

Sets the x, y and z coordinates of this vector.

setX(_x)¶

Parameters:: _x – float

Sets the x coordinate of this vector

setY(_y)¶

Parameters:: _y – float

Sets the y coordinate of this vector

setZ(_z)¶

Parameters:: _z – float

Sets the z coordinate of this vector
