double  zFar = 1.0,
bool  writeMask = true
 

osg::Depth::Depth const Depth dp,
const CopyOp copyop = CopyOp::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.
