# How to: Animate a 3D Rotation Using Key Frames (QuaternionAnimationUsingKeyFrames)
|
|
In the following example, <xref:System.Windows.Media.Animation.QuaternionAnimationUsingKeyFrames> is used to make a 3D object rotate. This animation uses the following key frames:
|
|
|
|
1. <xref:System.Windows.Media.Animation.LinearRotation3DKeyFrame> is used to create a smooth, linear interpolation between values.
|
|
|
|
2. <xref:System.Windows.Media.Animation.DiscreteRotation3DKeyFrame> is used to create sudden "jumps" between values (no interpolation).
|
|
|
|
3. <xref:System.Windows.Media.Animation.SplineRotation3DKeyFrame> is used to create a variable transition between values depending on the <xref:System.Windows.Media.Animation.SplineRotation3DKeyFrame.KeySpline%2A> property. In the example below, this part of the animation starts off slow but toward the end of the time segment, speeds up exponentially.
