I, too, am interested in this. Currently, I am caching everything except
nodes, but this doesn't cache the geometry. Here is the code:
//Set cache options
osg::ref_ptr<osgDB::ReaderWriter::Options> options = new
osgDB::ReaderWriter::Options;
if (m_bCache){
//Cache everything except Nodes.
options.get()->setObjectCacheHint(
(osgDB::ReaderWriter::Options::CacheHintOptions)
(osgDB::ReaderWriter::Options::CacheHintOptions::CACHE_IMAGES |
osgDB::ReaderWriter::Options::CacheHintOptions::CACHE_HEIGHTFIELDS
|
osgDB::ReaderWriter::Options::CacheHintOptions::CACHE_ARCHIVES |
osgDB::ReaderWriter::Options::CacheHintOptions::CACHE_OBJECTS));
}else{
//Don't cache
options.get()->setObjectCacheHint(
osgDB::ReaderWriter::Options::CACHE_NONE);
}
m_pModelGraph = osgDB::readNodeFile(m_poModel->GetPath(), options.get());
This gives me individual control over switch nodes, articulates, and
animations, but doesn't cache the geometry :(

Subject: Re: [osg-users] Cloning everything but Geode's/Drawables
I did look at that, but copying the top level node deep would copy
everything deep, and copying to top level node would copy everything
shallow. I really want to deep copy everything BUT the geodes. I don't see
how to do that without deep copying everything and then going back and
replacing all the geodes with the instances in the first node. I was hoping
to not have to do that.
