PlaneProjection.RotationX Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets or sets the number of degrees to rotate the object around the x-axis of rotation.
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
<PlaneProjection RotationX="double"/>
Property Value
Type: System.DoubleThe number of degrees to rotate the object around the x-axis of rotation. The default is 0.
Dependency property identifier field: RotationXProperty
The RotationX, RotationY, and RotationZ properties specify the number of degrees to rotate the object in space. For example, the RotationX property specifies rotating around the horizontal axis of the object. The following illustration demonstrates how the RotationX property rotates an object around the x-axis of rotation.

The RotationY property rotates around a line drawn vertically along the object (the y-axis of rotation).

The RotationZ property rotates around a line perpendicular to the object (a line that goes directly through the plane of the object).

These rotation properties can specify a negative value, which rotates the object a number of degrees in the opposite direction. In addition, the absolute number can be greater than 360, which rotates the object more than one full rotation.
You can change where the axis of rotation are positioned and therefore change the effect of rotation. For more information, see CenterOfRotationX, CenterOfRotationY, and CenterOfRotationZ.
