osg::Depth::Depth (    )

osg::Depth::Depth (  const Depth &    dp, const CopyOp &    copyop = CopyOp::SHALLOW_COPY )  [inline]

Copy constructor using CopyOp to manage deep vs shallow copy.

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.

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

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

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

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

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

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

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

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

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

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