Module Mathutils :: Class Quaternion

Class Quaternion

The Quaternion object

This object gives access to Quaternions in Blender.

Method Summary
New quaternion object.	`__init__(list, angle)` Create a new quaternion object from initialized values.
	`conjugate()` Set the quaternion to it's conjugate.
	`identity()` Set the quaternion to the identity quaternion.
	`inverse()` Set the quaternion to it's inverse
	`negate()` Set the quaternion to it's negative.
	`normalize()` Normalize the quaternion.
Euler object	`toEuler()` Return Euler representation of the quaternion.
Matrix object	`toMatrix()` Return a matrix representation of the quaternion.

Class Variable Summary
	`angle`: A scalar representing the amount of rotation in degrees.
	`axis`: Vector representing the axis of rotation.
	`magnitude`: The magnitude of the quaternion.
	`w`: The w value.
	`x`: The x value.
	`y`: The y value.
	`z`: The z value.

Method Details

init(list=None, angle=None)
(Constructor)

Create a new quaternion object from initialized values.

Example:

 quat = Mathutils.Quaternion()

Parameters:: list - A 3d or 4d list to initialize quaternion. 4d if intializing, 3d if will be used as an axis of rotation.
(type=PyList of int/float); angle - An arbitrary rotation amount around 'list'. List is used as an axis of rotation in this case.
(type=float (optional))

Returns:

It depends wheter a parameter was passed:

(list/angle): Quaternion object initialized with the given values;
(): An identity 4 dimensional quaternion.

(type=New quaternion object.)

conjugate()

Set the quaternion to it's conjugate.

identity()

Set the quaternion to the identity quaternion.

inverse()

Set the quaternion to it's inverse

negate()

Set the quaternion to it's negative.

normalize()

Normalize the quaternion.

toEuler()

Return Euler representation of the quaternion.

Returns:: Euler representation of the quaternion.
(type=Euler object)

toMatrix()

Return a matrix representation of the quaternion.

Returns:: A rotation matrix representation of the quaternion.
(type=Matrix object)
