Member Function Documentation

virtual void osg::BlendFunc::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::BlendFunc::compare (  const StateAttribute &    sa )  const [inline, virtual]

return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs. Implements osg::StateAttribute.

virtual void osg::BlendFunc::getAssociatedModes (  std::vector< GLMode > &    modes )  const [inline, virtual]

return the modes associated with this StateSet Reimplemented from osg::StateAttribute.

const int osg::BlendFunc::getDestination (    )  const [inline]

const int osg::BlendFunc::getSource (    )  const [inline]

osg::BlendFunc::META_StateAttribute (  osg   , BlendFunc   , BLENDFUNC    )
