Hi Robert,
I have changed the code a bit.
Now I create my statset (_myPreCreatedStateSet) at class construction.
I no longer clone bin 10.
I now only do this inside the inner check:
if( binList.find(10) != binList.end() )
{
binList[9] = new osgUtil::RenderBin();
binList[9]->setStateSet( _myPreCreatedStateSet );
(binList[9]->getRenderBinList())[9] = binList[10];
}
The only thing that annoy me now is the call to new().
Creating one bin as a member variable in my class and using it instead of the
call to new cause the system to crash. Double buffering I guess.
So maybe I can fix this by having two RenderBin instances in my class, and use
them every other call?
But, I suspect that it may not be enough? Would I need two per cull call that
is ran per frame? Say that I in the future render with 4 different cameras and
cull the world 4 times. Would I then need 4*2 bin instances to use instead of
calling new()?
Regards,
Viggo
