Quaternions allow you to interpolate between rotation transformations applied to an object, thereby making it easier to compute smooth animations of rotations. A quaternion represents an axis of rotation and a rotation around that axis. It's possible to individually define the axis and angle of rotation of the starting and ending positions of a rotated object ,but the intermediate positions of that object during an animation are computationally uncertain. By determining a quaternion that represents the original orientation of a 3-D object and one that represents its destination orientation, you can smoothly interpolate between those orientations.
In XAML, the delimiter between the values of a Quaternion can be either a comma or a space.
Some cultures might use the comma character as the decimal delimiter instead of the period character. XAML processing for invariant culture defaults to en-US in most XAML processor implementations, and expects the period to be the decimal delimiter. You should avoid using the comma character as the decimal delimiter if specifying a Quaternion in XAML, because that will clash with the string type conversion of a Quaternion attribute value into its components.
