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

osg::TexEnv::META_StateAttribute ( osg  ,
TexEnv  ,
TEXENV   
)

virtual bool osg::TexEnv::isTextureAttribute (  )  const [inline, virtual]

Return true if StateAttribute is a type which controls texturing and needs to be issued w.r.t to specific texture unit.

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.

void osg::TexEnv::setMode ( Mode  mode  )  [inline]

Mode osg::TexEnv::getMode (  )  const [inline]

void osg::TexEnv::setColor ( const Vec4 color  )  [inline]

Vec4& osg::TexEnv::getColor (  )  [inline]

const Vec4& osg::TexEnv::getColor (  )  const [inline]

virtual void osg::TexEnv::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.
