## Quaternion class

Quaternion is usually used to perform rotation in computer graphics.



The Quaternion type exposes the following members:

### Constructors

| [`__init__(self)`](/3d/python-net/aspose.threed.utilities/quaternion/__init__/#) | Constructs a new instance of Quaternion |


### Properties
| Property | Description |
| :- | :- |
| [length](/3d/python-net/aspose.threed.utilities/quaternion/length) | Gets the length of the quaternion |
| [IDENTITY](/3d/python-net/aspose.threed.utilities/quaternion/identity) | The Identity quaternion. |
| [w](/3d/python-net/aspose.threed.utilities/quaternion/w) | The w component. |
| [x](/3d/python-net/aspose.threed.utilities/quaternion/x) | The x component. |
| [y](/3d/python-net/aspose.threed.utilities/quaternion/y) | The y component. |
| [z](/3d/python-net/aspose.threed.utilities/quaternion/z) | The z component. |
