Quaternion(Vector3D, Double)
Initializes a new instance of the Quaternion structure.
public:
Quaternion(System::Windows::Media::Media3D::Vector3D axisOfRotation, double angleInDegrees);
public Quaternion (System.Windows.Media.Media3D.Vector3D axisOfRotation, double angleInDegrees);
new System.Windows.Media.Media3D.Quaternion : System.Windows.Media.Media3D.Vector3D * double -> System.Windows.Media.Media3D.Quaternion
Public Sub New (axisOfRotation As Vector3D, angleInDegrees As Double)
Parameters
- angleInDegrees
- Double
Angle to rotate around the specified axis, in degrees.
Remarks
The W property of the quaternion is computed automatically.

Quaternion(Double, Double, Double, Double)
Initializes a new instance of the Quaternion structure.
public:
Quaternion(double x, double y, double z, double w);
public Quaternion (double x, double y, double z, double w);
new System.Windows.Media.Media3D.Quaternion : double * double * double * double -> System.Windows.Media.Media3D.Quaternion
Public Sub New (x As Double, y As Double, z As Double, w As Double)
Parameters
- x
- Double
Value of the new Quaternion's X coordinate.
- y
- Double
Value of the new Quaternion's Y coordinate.
- z
- Double
Value of the new Quaternion's Z coordinate.
- w
- Double
Value of the new Quaternion's W coordinate.
Remarks
For the axis (x, y, z) and angle of rotation theta, the w
value for the quaternion is:
w = cos(theta/2)
Note that if you use the Vector3D constructor, the fourth parameter is the angle, in degrees, and the w calculation is performed for you.
