Constructor & Destructor Documentation

◆ TexGen() [1/2]

osg::TexGen::TexGen ( )

◆ TexGen() [2/2]

osg::TexGen::TexGen ( const TexGen texgen,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
)
inline

Copy constructor using CopyOp to manage deep vs shallow copy.

◆ ~TexGen()

virtual osg::TexGen::~TexGen ( void  )
protectedvirtual

Member Function Documentation

◆ apply()

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.

◆ compare()

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.

◆ getMode()

Mode osg::TexGen::getMode ( ) const
inline

◆ getModeUsage()

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

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

◆ getPlane() [1/2]

Plane & osg::TexGen::getPlane ( Coord  which)

◆ getPlane() [2/2]

const Plane & osg::TexGen::getPlane ( Coord  which) const

◆ isTextureAttribute()

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.

◆ META_StateAttribute()

osg::TexGen::META_StateAttribute ( osg  ,
TexGen  ,
TEXGEN   
)

◆ setMode()

void osg::TexGen::setMode ( Mode  mode)
inline

◆ setPlane()

void osg::TexGen::setPlane ( Coord  which,
const Plane plane 
)

◆ setPlanesFromMatrix()

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.
