CubicEase Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Represents an easing function that creates an animation that accelerates and/or decelerates using the formula f(t) = t3.
System.Windows::DependencyObject
System.Windows.Media.Animation::EasingFunctionBase
System.Windows.Media.Animation::CubicEase
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
The CubicEase type exposes the following members.
| Name | Description | |
|---|---|---|
 | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
| EasingMode | Gets or sets a value that specifies how the animation interpolates. (Inherited from EasingFunctionBase.) |
| Name | Description | |
|---|---|---|
 | CheckAccess | Determines whether the calling thread has access to this object. (Inherited from DependencyObject.) |
| ClearValue | Clears the local value of a dependency property. (Inherited from DependencyObject.) |
| Ease | Transforms normalized time to control the pace of an animation. (Inherited from EasingFunctionBase.) |
 | EaseInCore | Provides the logic portion of the easing function that you can override to produce the EaseIn mode of the custom easing function. (Overrides EasingFunctionBase::EaseInCore(Double).) |
| Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetAnimationBaseValue | Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadLocalValue | Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.) |
| SetValue | Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
You can control whether the animation accelerates, decelerates, or both by specifying the EasingMode. The following graph demonstrates the different values of EasingMode, where f(t) represents the animation progress and t represents time.
The formula used for this function is the following.
f(t) = t3
In addition to using the easing functions included in the run-time, you can create your own custom easing functions by inheriting from EasingFunctionBase.
The following example applies a CubicEase easing function to a DoubleAnimation to create a decelerating animation.
