[Opensg-users] IDBuffer

[Michael Raab]

Hi Carsten,

 

I'm trying to convert our IdBuffer selection handling from 1.8 to 2.0. In 1.8 used custom renderEnter/renderLeave functions to achieve the id-coded rendering, i.e.

 

    this->_ract->registerEnterFunction(OSG::Geometry::getClassType(),
                                OSG::osgTypedFunctionFunctor2CPtrRef<
                                    OSG::Action::ResultE,
                                    OSG::CNodePtr,
                                    OSG::Action *                      >(
                                    IDBufferSelectionHelper::onEnterGeometry ) );

with

 

class IDBufferSelectionHelper {

static osg::Action::ResultE onEnterGeometry( osg::CNodePtr& pNode, osg::Action * action );

}

 

Is it possible to achieve this with OpenSG 2.0, too? I tried something like this:

    this->_ract->registerEnterFunction(OSG::Geometry::getClassType(),
        boost::bind(&IDBufferSelectionHelper::onEnterGeometry, this));

with

class IDBufferSelectionHelper {

static OSG::Action::ResultE onEnterGeometry( const OSG::NodeCore* core, OSG::Action * action );

}

 

But to me it seems that the called object needs to inherit from NodeCore? Could you please give me a hint if and how this is solvable?

 

Thanks,

Michael
