Inheriting render states
The state set of a node will affect the current node and its children. For example, the osg::PolygonMode attribute set to node transformation1 will make all of its children display as outlined. However, a child node's state set can override its parent's, that is, the rendering states will be inherited from the parent node unless a child node changes the behavior. The following image shows how different polygon mode states are traversed an imaginary scene graph:
Sometimes you may want different behaviors. For example, in common 3D editor software, users can load multiple models from files and render all of them as textured, ...
