# How to: Apply Material to the Front and Back of a 3D Object
The following example shows how to apply a <xref:System.Windows.Media.Media3D.Material> to the front and back of a 3D object and animate the object to show both sides of the object. The <xref:System.Windows.Media.Media3D.GeometryModel3D.Material%2A> property of a <xref:System.Windows.Media.Media3D.GeometryModel3D> is used to apply a red <xref:System.Windows.Media.Brush> to the front side of the object and the <xref:System.Windows.Media.Media3D.GeometryModel3D.BackMaterial%2A> property of the <xref:System.Windows.Media.Media3D.GeometryModel3D> is used to apply a blue <xref:System.Windows.Media.Brush> to the back side of the object. The code below shows the application of the materials to the object:
