3/12/2014

This class represents an easing function that creates an animation that accelerates or decelerates using the formula f(t) = t3.

Syntax

class IXRCubicEase : public IXREasingFunctionBase

Inheritance Hierarchy

IXRDependencyObject

    IXREasingFunctionBase

        IXRCubicEase

Methods

This class provides no new methods. All its methods are inherited from IXREasingFunctionBase.

Thread Safety

Members of this class are thread safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

You can control whether the animation accelerates, decelerates, or both, by passing one of the XREasingMode enumerated values to the inherited IXREasingFunctionBase::SetEasingMode method. The following graph demonstrates the different values of the easing mode, where f(t) represents the animation progress and t represents time.

When you create a class instance, use an IXRCubicEasePtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.

You can apply this easing function to an animation in Microsoft Silverlight 3 XAML. For information about the differences between XAML in Silverlight for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and Silverlight for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the CubicEase Class on MSDN.

There are several other easing functions besides IXRCubicEase, which you can explore using the following sample:
