Member Function Documentation

virtual void osg::TexGen::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::TexGen::compare ( const StateAttribute sa) const
inlinevirtual

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

Implements osg::StateAttribute.

References COMPARE_StateAttribute_Parameter, and COMPARE_StateAttribute_Types.

Mode osg::TexGen::getMode ( ) const
inline
virtual bool osg::TexGen::getModeUsage ( StateAttribute::ModeUsage ) const
inlinevirtual

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

References osg::StateAttribute::ModeUsage::usesTextureMode().

Plane& osg::TexGen::getPlane ( Coord  which)
const Plane& osg::TexGen::getPlane ( Coord  which) const
virtual bool osg::TexGen::isTextureAttribute ( ) const
inlinevirtual

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.

TexGen  ,
TEXGEN   
)
void osg::TexGen::setMode ( Mode  mode)
inline
void osg::TexGen::setPlane ( Coord  which,
const Plane plane 
)
void osg::TexGen::setPlanesFromMatrix ( const Matrixd matrix)

Set the tex gen planes from specified matrix. Typical usage would be to pass in a projection matrix to set up projective texturing.
