Constructor & Destructor Documentation

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

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.

Definition at line 62 of file TexGen.h.

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

Definition at line 110 of file TexGen.h.

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

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

Definition at line 78 of file TexGen.h.

Here is the call graph for this function:

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.

Definition at line 59 of file TexGen.h.

osg::TexGen::META_StateAttribute ( osg  ,
TexGen  ,
TEXGEN   
)
void osg::TexGen::setMode ( Mode  mode)
inline

Definition at line 108 of file TexGen.h.

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.
