Hi, this issue is solved, too.
this->_ract->registerEnterFunction(OSG::Geometry::getClassType(),
boost::bind(IDBufferSelectionHelper::onEnterGeometry, _1, _2));
boost::bind(IDBufferSelectionHelper::onEnterGeometry, _1, _2));
did the job. Thus IDbuffer selection via back buffer rendering works again.
What I would like to achieve additionally is do the selection via FrameBufferObject.
Looking at the source code and examples I have no clue to render a or several viewports to a FBO.
Can someone give a hint or some code snippet?
Thanks in advance,
Michael

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 ) );
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));
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
