Point3DAnimationBase.GetCurrentValueCore Method

Definition

Namespace:

System.Windows.Media.Animation

Assembly:

PresentationCore.dll

Calculates a value that represents the current value of the property being animated, as determined by the Point3DAnimation.

protected:
 abstract System::Windows::Media::Media3D::Point3D GetCurrentValueCore(System::Windows::Media::Media3D::Point3D defaultOriginValue, System::Windows::Media::Media3D::Point3D defaultDestinationValue, System::Windows::Media::Animation::AnimationClock ^ animationClock);

protected abstract System.Windows.Media.Media3D.Point3D GetCurrentValueCore (System.Windows.Media.Media3D.Point3D defaultOriginValue, System.Windows.Media.Media3D.Point3D defaultDestinationValue, System.Windows.Media.Animation.AnimationClock animationClock);

abstract member GetCurrentValueCore : System.Windows.Media.Media3D.Point3D * System.Windows.Media.Media3D.Point3D * System.Windows.Media.Animation.AnimationClock -> System.Windows.Media.Media3D.Point3D

Protected MustOverride Function GetCurrentValueCore (defaultOriginValue As Point3D, defaultDestinationValue As Point3D, animationClock As AnimationClock) As Point3D

Parameters

defaultOriginValue

Point3D

The origin value provided to the animation if the animation does not have its own start value.

defaultDestinationValue

Point3D

The destination value provided to the animation if the animation does not have its own destination value.

animationClock

AnimationClock

The AnimationClock which can generate the CurrentTime or CurrentProgress value to be used by the animation to generate its output value.

Returns

Point3D

The calculated value of the property, as determined by the current animation.

Remarks

The value of the defaultOriginValue parameter depends on the animation's position in the composition chain:

• If the animation is in the first position in a composition chain and it replaces another animation, defaultOriginValue is the output of that animation at the time it was replaced.

• If the animation is in the first position in a composition chain and no animation exists to replace, defaultOriginValue is the base value of the animated property.

• If this animation is not in the first position of a composition chain, then defaultOriginValue is the value that is returned by the previous animation in the composition chain that has an AnimationClock that is not Stopped.

The value of the defaultDestinationValue parameter depends on whether there is a previous property Trigger composition layer.

• If there is a previous property Trigger composition layer, defaultDestinationValue is the output from that layer.

• If there is no previous composition layer, defaultDestinationValue is the base value of the property that you are animating.
