Methods

Method	Description
IXRPlaneProjection::GetCenterOfRotationX	Retrieves the x-coordinate of the center of rotation of the object to rotate.
IXRPlaneProjection::GetCenterOfRotationY	Retrieves the y-coordinate of the center of rotation of the object to rotate.
IXRPlaneProjection::GetCenterOfRotationZ	Retrieves the z-coordinate of the center of rotation of the object to rotate.
IXRPlaneProjection::GetGlobalOffsetX	Retrieves the translation distance of the object along the x-axis of the screen.
IXRPlaneProjection::GetGlobalOffsetY	Retrieves the translation distance of the object along the y-axis of the screen.
IXRPlaneProjection::GetGlobalOffsetZ	Retrieves the translation distance of the object along the z-axis of the screen.
IXRPlaneProjection::GetLocalOffsetX	Retrieves the translation distance of the object along the x-axis of the screen.
IXRPlaneProjection::GetLocalOffsetY	Retrieves the translation distance of the object along the y-axis of the object.
IXRPlaneProjection::GetLocalOffsetZ	Retrieves the translation distance of the object along the z-axis of the object.
IXRPlaneProjection::GetProjectionMatrix	Retrieves the IXRMatrix3D object that defines a 3-D transformation.
IXRPlaneProjection::GetRotationX	Retrieves the number of degrees to rotate the object around the x-axis of rotation.
IXRPlaneProjection::GetRotationY	Retrieves the number of degrees to rotate the object around the y-axis of rotation.
IXRPlaneProjection::GetRotationZ	Retrieves the number of degrees to rotate the object around the z-axis of rotation.
IXRPlaneProjection::SetCenterOfRotationX	Sets the x-coordinate of the center of rotation of the object to rotate.
IXRPlaneProjection::SetCenterOfRotationY	Sets the y-coordinate of the center of rotation of the object to rotate.
IXRPlaneProjection::SetCenterOfRotationZ	Sets the z-coordinate of the center of rotation of the object to rotate.
IXRPlaneProjection::SetGlobalOffsetX	Sets the translation distance of the object along the x-axis of the screen.
IXRPlaneProjection::SetGlobalOffsetY	Sets the translation distance of the object along the y-axis of the screen.
IXRPlaneProjection::SetGlobalOffsetZ	Sets the translation distance of the object along the z-axis of the screen.
IXRPlaneProjection::SetLocalOffsetX	Sets the translation distance of the object along the x-axis of the screen.
IXRPlaneProjection::SetLocalOffsetY	Sets the translation of the object along the y-axis of the screen.
IXRPlaneProjection::SetLocalOffsetZ	Sets the translation distance of the object along the z-axis of the screen.
IXRPlaneProjection::SetRotationX	Sets the number of degrees to rotate the object around the x-axis of rotation.
IXRPlaneProjection::SetRotationY	Sets the number of degrees to rotate the object around the y-axis of rotation.
IXRPlaneProjection::SetRotationZ	Sets the number of degrees to rotate the object around the z-axis of rotation.

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

To make an object appear as if it is projecting into three-dimensional space, you can define a perspective transformation for it by using the methods of IXRPlaneProjection.

To apply a 3-D transformation to an object that derives from IXRUIElement, create an IXRPlaneProjection object and then provide it in a call to IXRUIElement::SetProjection.

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

You can also define a perspective transformation in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the PlaneProjection Class on MSDN.
