Light Class

Model3D object that represents lighting applied to a 3-D scene.

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)

'Declaration
Public MustInherit Class Light _
	Inherits Model3D
'Usage
Dim instance As Light
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

Because lights are models themselves, you can apply transformations and animations to them, just as with other models.

The following excerpts show examples of two Light types, DirectionalLight and AmbientLight.
