Light Filter

This example shows how to implement a custom filter as a self-installing plug-in that handles light objects. The Light filter plug-in is installed when the example workgroup is installed and automatically added to the filter menu of the Scene Explorer view. The light filter plug-in provides two filters: LightOnFilter and LightOffFilter. When the LightOnFilter is the active selection filter, the Scene Explorer will only display the light objects that have the intensity parameter value > 0. When the LightOffFilter is the active selection filter, the Scene Explorer will only display the light objects that have the intensity parameter value set to 0.
