osg::TexEnvFilter::TexEnvFilter ( const TexEnvFilter texenv,
const CopyOp copyop = CopyOp::SHALLOW_COPY

Member Function Documentation

virtual void osg::TexEnvFilter::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::TexEnvFilter::compare ( const StateAttribute sa) const [inline, virtual]

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

Implements osg::StateAttribute.

virtual bool osg::TexEnvFilter::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.
