Constructor & Destructor Documentation

osg::TexEnv::TexEnv ( Mode  mode = MODULATE)
osg::TexEnv::TexEnv ( const TexEnv texenv,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
) [inline]

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

virtual void osg::TexEnv::apply ( State ) const [virtual]

apply the OpenGL state attributes.

The render info for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.

Reimplemented from osg::StateAttribute.

virtual int osg::TexEnv::compare ( const StateAttribute sa) const [inline, virtual]

Return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

Implements osg::StateAttribute.
