well, thanks for answering,
actually, the image gets distorted... Just to highlight, we're using camera
space coordinates.. so, the plane corners are something like
OSG::Pnt3f( -w, -h, -near );
OSG::Pnt3f( w, -h, -near );
OSG::Pnt3f( w, h, -near );
OSG::Pnt3f( -w, h, -near );
where w and h measure both half the size of width and height of my
projection plane in camera space.. so, they map each corner of the
projection plane.. we set those very same corners for both decorators... as
follow:
_decoLeft = OSG::ProjectionCameraDecorator::create();
_decoLeft->setDecoratee( _mainCamera );
_decoLeft->setLeftEye( true );
_decoLeft->setEyeSeparation( 0.06f );
_decoLeft->editMFSurface()->push_back( OSG::Pnt3f( -w, -h, -near )
);
_decoLeft->editMFSurface()->push_back( OSG::Pnt3f( w, -h, -near )
);
_decoLeft->editMFSurface()->push_back( OSG::Pnt3f( w, h, -near )
);
_decoLeft->editMFSurface()->push_back( OSG::Pnt3f( -w, h, -near )
);
_decoLeft->setUser( userNode );
_leftViewport->setCamera( _decoLeft );
_decoRight = OSG::ProjectionCameraDecorator::create();
_decoRight->setDecoratee( _mainCamera );
_decoRight->setLeftEye( false );
_decoRight->setEyeSeparation( 0.06f );
_decoRight->editMFSurface()->push_back( OSG::Pnt3f( -w, -h, -near )
);
_decoRight->editMFSurface()->push_back( OSG::Pnt3f( w, -h, -near )
);
_decoRight->editMFSurface()->push_back( OSG::Pnt3f( w, h, -near )
);
_decoRight->editMFSurface()->push_back( OSG::Pnt3f( -w, h, -near )
);
_decoRight->setUser( userNode );
_rightViewport->setCamera( _decoRight );
this produces distorted images... any hints?
thanks
