Hi Carsten,
I tried it your way. I used MaterialGroup::renderEnter/Leave as draft for my
implementation.
Action::ResultE onEnterMaterialGroup( CNodePtr& pNode, Action * action )
{
RenderAction *ra = dynamic_cast<RenderAction *>(action);
MaterialGroupPtr mg = MaterialGroupPtr::dcast(pNode);
Action::ResultE r = mg->renderEnter(action);
osg::ChunkMaterialPtr m =
SelectionHelper::getInstance()->getIDMaterial(osg::getContainerId(pNode));
ra->setMaterial(m.getCPtr(), action->getActNode());
return r;
}
Action::ResultE onLeaveMaterialGroup( CNodePtr& pNode, Action * action )
{
RenderAction *ra = dynamic_cast<RenderAction *>(action);
MaterialGroupPtr mg = MaterialGroupPtr::dcast(pNode);
return mg->renderLeave(action);
}
The problem is
mg->renderEnter(action) and
mg->renderLeave(action)
are protected. Ideas?
Thanks,
Michael
