This class defines an animation segment that has its own target x-y point values and interpolation method for an IXRPointAnimationUsingKeyFrames animation.

Syntax

class IXRPointKeyFrame : public IXRDependencyObject

Methods

Method	Description
IXRPointKeyFrame::GetKeyTime	Retrieves the time at which the target x-y point values for this key frame are reached.
IXRPointKeyFrame::GetValue	Retrieves the target x-y point values for this key frame.
IXRPointKeyFrame::SetKeyTime	Sets the time at which the target x-y point values for this key frame are reached.
IXRPointKeyFrame::SetValue	Sets the target x-y point values for this key frame.

Remarks

IXRPointKeyFrame is a class that defines key frames by using x-y point values for three techniques of key frame animation: IXRDiscretePointKeyFrame, IXRLinearPointKeyFrame, and IXRSplinePointKeyFrame.

To animate an x-y point by using key frames, you can define an IXRPointAnimationUsingKeyFrames animation and populate its key-frames collection with one or more objects that define the key frames, such as IXRDiscretePointKeyFrame, IXRLinearPointKeyFrame, or IXRSplinePointKeyFrame
