Remarks

For more info about using PerspectiveTransform3D, see the UIElement.Transform3D property.

Adding a PerspectiveTransform3D element to a scene with no other 3-D transforms will not change the appearance of any 2-D elements. It will preserve the X and Y coordinates in the plane of Z=0. To take advantage of the perspective effect, you need to use CompositeTransform3D in conjunction with PerspectiveTransform3D.

Following the guidelines of the The Direct3D Transformation Pipeline, PerspectiveTransform3D represents a projection transform. In comparison, CompositeTransform3D represents a world or view transform. Because of this, PerspectiveTransform3D should usually be applied at the root of the XAML scene. In most cases, this would be the Page element.

Constructors

PerspectiveTransform3D()

Initializes a new instance of the PerspectiveTransform3D class.

Properties

Depth	Gets or sets the distance in pixels to the plane where z=0.
DepthProperty	Identifies the Depth dependency property.
Dispatcher	Always returns `null` in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the `DispatcherQueue` that this object is associated with. The `DispatcherQueue` represents a facility that can access the `DependencyObject` on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
OffsetX	Gets or sets the x-offset in pixels for the perspective's origin from the center of the element.
OffsetXProperty	Identifies the OffsetX dependency property.
OffsetY	Gets or sets the y-offset in pixels for the perspective's origin from the center of the element.
OffsetYProperty	Identifies the OffsetY dependency property.

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
