module Occluder_node:sig..end
Osg.Occluder_node is a Osg.Group node which allows
Osg.Occluder_nodeing between children.
Typical uses would be for objects which might need to be rendered differently at different times, for instance a OccluderNode could be used to represent the different states of a traffic light.
