Member Function Documentation

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

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

Function osg::Depth::getFunction (   )  const [inline]

virtual bool osg::Depth::getModeUsage (  ModeUsage &  usage  )  const [inline, virtual]

Return the modes associated with this StateAttribute. Reimplemented from osg::StateAttribute.

bool osg::Depth::getWriteMask (   )  const [inline]

double osg::Depth::getZFar (   )  const [inline]

double osg::Depth::getZNear (   )  const [inline]

osg::Depth::META_StateAttribute (  osg  , Depth  , DEPTH  )

void osg::Depth::setFunction (  Function  func  )  [inline]

void osg::Depth::setRange (  double  zNear, double  zFar )  [inline]

void osg::Depth::setWriteMask (  bool  mask  )  [inline]

void osg::Depth::setZFar (  double  zFar  )  [inline]

void osg::Depth::setZNear (  double  zNear  )  [inline]
