Remarks

This class is used to create a perspective transform (a 3-D effect) on an object. For example, you can create the illusion that an object is rotated toward or away from you.

Image with perspective transform

Image with perspective transform applied.

Although the preceding illustration shows a perspective transform applied to a simple image, you can apply one to any UIElement, including controls. For example, you could apply the effect to a Grid that in turn contains a TextBox and Button. Despite the controls being rotated, the user could type into the TextBox and click the Button (assuming the controls are visible).

Another common scenario for using perspective transforms is to arrange objects in relation to one another to create a 3-D effect, as shown in the following illustration.

Stacking objects to create a 3-D effect

Shows stacking objects in 3d effect.

Besides creating static 3-D effects, you can animate the perspective transform properties to create moving 3-D effects.

Run this sample

PlaneProjection has 12 properties you can use to control the rotation and positioning of an object: RotationX, RotationY, RotationZ, CenterOfRotationX, CenterOfRotationY, CenterOfRotationZ, GlobalOffsetX, GlobalOffsetY, GlobalOffsetZ, LocalOffsetX, LocalOffsetY, and LocalOffsetZ. The following sample allows you to experiment with these properties.

Run this sample

NoteNote:

Perspective transforms are not equivalent to a 3-D engine, however, they can be used to make 2-D Silverlight content appear as if it is drawn on a 3-D plane.

Examples

To apply a perspective transform to a UIElement, set the UIElement object's Projection property to a PlaneProjection. The PlaneProjection defines how the transform is rendered in space. The following example shows a simple case.

Run this sample

<StackPanel Margin="35" Background="Gray">
    <StackPanel.Projection>
        <PlaneProjection RotationX="-35" RotationY="-35" RotationZ="15"  />
    </StackPanel.Projection>
    <TextBlock Margin="10">Type Something Below</TextBlock>
    <TextBox Margin="10"></TextBox>
    <Button Margin="10" Content="Click" Width="100" />
</StackPanel>
