Örnekler
Aşağıdaki örnekte, 3B bir görünümde oluşturma gösterilmektedir SpotLight .
<!-- A SpotLight is used to light the scene. The InnerConeAngle and OuterConeAngle are used
to control the size of the light cone created by the SpotLight. The Direction and Position
properties determine where the SpotLight is pointing in the scene. In this example, the Position
of the SpotLight is set so that the SpotLight is only illuminating the upper right-hand corner
of the 3D object. -->
