enum osg::Fog::Mode |
osg::Fog::Fog | ( | ) |
Copy constructor using CopyOp to manage deep vs shallow copy.
virtual osg::Fog::~Fog | ( | ) | [protected, virtual] |
virtual void osg::Fog::apply | ( | State & | state | ) | const [virtual] |
apply the OpenGL state attributes. The global state for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.
Implements osg::StateAttribute.
virtual int osg::Fog::compare | ( | const StateAttribute & | sa | ) | const [inline, virtual] |
return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.
Implements osg::StateAttribute.
