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.

virtual osg::TexEnv::~TexEnv void   )  [protected, virtual]
 


Member Function Documentation

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.

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.

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

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

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

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.
