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.

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

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