Examples

The following example shows how to place a button, a 2-D object, on a 3-D object. Note that you must set the IsVisualHostMaterial attached property on the material on which you wish to have the 2-D visual placed.

<Viewport3D>
    <Viewport3D.Camera>
        <PerspectiveCamera Position="0, 0, 4"/>
    </Viewport3D.Camera>
    
    <!-- Button on 3D -->
    <Viewport2DVisual3D>
        <!-- Give the plane a slight rotation -->
        <Viewport2DVisual3D.Transform>
            <RotateTransform3D>
                <RotateTransform3D.Rotation>
                    <AxisAngleRotation3D Angle="40" Axis="0, 1, 0" />
                </RotateTransform3D.Rotation>
            </RotateTransform3D>
        </Viewport2DVisual3D.Transform>
        
        <!-- The Geometry, Material, and Visual for the Viewport2DVisual3D -->
        <Viewport2DVisual3D.Geometry>
            <MeshGeometry3D Positions="-1,1,0 -1,-1,0 1,-1,0 1,1,0"
                            TextureCoordinates="0,0 0,1 1,1 1,0" TriangleIndices="0 1 2 0 2 3"/>
        </Viewport2DVisual3D.Geometry>

        <Viewport2DVisual3D.Material>
            <DiffuseMaterial Viewport2DVisual3D.IsVisualHostMaterial="True" Brush="White"/>
        </Viewport2DVisual3D.Material>                               
        
        <Button>Hello, 3D</Button>
    </Viewport2DVisual3D>
    
    <!-- Lights -->
    <ModelVisual3D>
        <ModelVisual3D.Content>
            <DirectionalLight Color="#FFFFFFFF" Direction="0,0,-1"/>
        </ModelVisual3D.Content>
    </ModelVisual3D>
</Viewport3D>

Remarks

Viewport2DVisual3D enables you to place interactive 2-D content on a 3-D object. Its counterpart is the Viewport3DVisual class, which is a 2-D visual with 3-D children.

Viewport2DVisual3D is introduced in the .NET Framework version 3.5.

HasAnimatedProperties	Gets a value that indicates whether this Visual3D has any animated properties. (Inherited from Visual3D)
IsSealed	Gets a value that indicates whether this instance is currently sealed (read-only). (Inherited from DependencyObject)
Material	Gets or sets the material that describes the appearance of the 3-D object.
Transform	Gets or sets the transformation that is applied to the 3-D object. (Inherited from Visual3D)

Gets or sets a value that specifies whether a material should be interactive.

Methods

AddVisual3DChild(Visual3D)	Defines the parent-child relationship between two 3-D visuals. (Inherited from Visual3D)
ApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior)	Applies the effect of a given AnimationClock to a given dependency property. The effect of the new AnimationClock on any current animations is determined by the value of the `handoffBehavior` parameter. (Inherited from Visual3D)
ApplyAnimationClock(DependencyProperty, AnimationClock)	Applies the effect of a given AnimationClock to a given dependency property. (Inherited from Visual3D)
BeginAnimation(DependencyProperty, AnimationTimeline, HandoffBehavior)	Initiates an animation sequence for the DependencyProperty object, based on both the specified AnimationTimeline and HandoffBehavior. (Inherited from Visual3D)
BeginAnimation(DependencyProperty, AnimationTimeline)	Initiates an animation sequence for the DependencyProperty object, based on the specified AnimationTimeline. (Inherited from Visual3D)
CheckAccess()	Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject)
ClearValue(DependencyProperty)	Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject)

GetType()	Gets the Type of the current instance. (Inherited from Object)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject)
GetVisual3DChild(Int32)	Returns the specified Visual3D in the parent Visual3DCollection. (Inherited from Visual3D)
InvalidateProperty(DependencyProperty)	Re-evaluates the effective value for the specified dependency property. (Inherited from DependencyObject)

OnVisualParentChanged(DependencyObject)	Called when the parent of the 3-D visual object is changed. (Inherited from Visual3D)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject)
RemoveVisual3DChild(Visual3D)	Removes the parent-child relationship between two 3-D visuals. (Inherited from Visual3D)
SetCurrentValue(DependencyProperty, Object)	Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject)
SetIsVisualHostMaterial(Material, Boolean)	Sets the value of the IsVisualHostMaterial attached property to a specified element.
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject)
