class SG_EXPORT osg::GeoState: public Object

Encapsulates OpenGL state modes and attributes.

Inheritance:

Public Classes
enum AttributeType

Public Methods
GeoState()
static GeoState* instance()
virtual Object* clone() const
virtual bool isSameKindAs(Object* obj)
const char* className() const
void setGlobalDefaults(): set all the modes to on or off so that it defines a complete state, typically used for a default global state
void setAllToInherit(): set all the modes to inherit, typically used to signifiy nodes which inherit all of their modes for the global state

Documentation

Encapsulates OpenGL state modes and attributes. Used to specificy textures etc of osg::GeoSet's which hold references to a single osg::GeoState. GeoState can be shared between GeoSet's and is recommend if possible as it minimize expensive state changes in the graphics pipeline.
