Hi OpenSG users,
in my application i have a fairly big library of models which i use
as prototypes
to build different pieces of a scene. Till the time being I just cloned the
prototype nodes and dragged then into the scene, but since the number of
traversed nodes is growing and growing, I am planning to make some model
optimization.
The first step is to unshare all the geometry cores to apply the other
optimizations (i.e. flushing of transformations inside the geometries).
I have written a small optimizer to unshared the geo cores which basically
looks like:
osg::MFNodePtr parents = curNode->getCore()->getParents();
printf ("Node %s has %d parents\n", osg::getName (curNode),
parents.size());
if (parents.size()>1) // unshare this baby
{
osg::GeometryPtr core = osg::GeometryPtr::dcast
(curNode->getCore());
osg::GeometryPtr newCore = core->clone ();
beginEditCP( newCore );
OSG::separateProperties( newCore );
endEditCP( newCore );
beginEditCP( curNode, osg::Node::CoreFieldMask );
curNode->setCore (newCore);
endEditCP( curNode, osg::Node::CoreFieldMask );
printf ("splitted\n");
}
As long as I just do the optimize and dump the model, all seems to work
fine: the geometries are unshared.
My problem is that my app is working in a cluster environment, so when I do:
Node= prototypeNode->clone ();
Optimize (Node);
clientsceneRoot->addChild (Node);
in the server window doesn't appear any geometry. Probably I am messing up
with the change lists, but I can't see where is my problem...
thanks
E.
