public:
property Rotation3DKeyFrameCollection^ KeyFrames {
	Rotation3DKeyFrameCollection^ get ();
	void set (Rotation3DKeyFrameCollection^ value);
}
<object>
  <Rotation3DKeyFrameCollection .../>
</object>

Property Value

Type: System.Windows.Media.Animation::Rotation3DKeyFrameCollection
The collection of Rotation3DKeyFrame objects that define the animation. The default value is Empty.

In the following example, Rotation3DAnimationUsingKeyFrames is used to make a 3D object rotate while its axis of rotation animates resulting in a "wobble". This animation uses the following key frames:

  1. LinearRotation3DKeyFrame is used to create a smooth, linear interpolation between values.

  2. DiscreteRotation3DKeyFrame is used to create sudden "jumps" between values (no interpolation).

  3. SplineRotation3DKeyFrame is used to create a variable transition between values depending on the KeySpline property. In the example below, this part of the animation starts off slow but toward the end of the time segment, speeds up exponentially.
