Hi Christian,
Also you could try to activate caching and sharing of nodes/textures:
Here is some snippet from my code:
<snip>
{
osgDB::SharedStateManager::ShareMode mode =
osgDB::SharedStateManager::SHARE_NONE;// =
osgDB::SharedStateManager::SHARE_ALL;
mode = mConfig.mGlobalState.mShareStates ?
static_cast<osgDB::SharedStateManager::ShareMode>(mode |
osgDB::SharedStateManager::SHARE_STATESETS) : mode;
mode = mConfig.mGlobalState.mShareTextures
?static_cast<osgDB::SharedStateManager::ShareMode>(mode |
osgDB::SharedStateManager::SHARE_TEXTURES) : mode;
osgDB::Registry::instance()->getOrCreateSharedStateManager()->setShareMode(mode);
}
{
//setup caching
osgDB::Options::CacheHintOptions opts;
opts = static_cast<osgDB::Options::CacheHintOptions>(opts
|osgDB::Options::CACHE_IMAGES);
opts = static_cast<osgDB::Options::CacheHintOptions>(opts
|osgDB::Options::CACHE_NODES);
opt->setObjectCacheHint(static_cast<osgDB::Options::CacheHintOptions>(opts));
osgDB::Registry::instance()->setOptions(opt);
}
</snip>
Cheers

Hi,
when I use osgDB::readNodeFile on several objects, and those objects
all reference the same texture file on disk - is it possible to make
OSG use the same texture on all loaded subgraphs? Currently it seems
like I have the same texture loaded over and over, consuming precious
texture memory (and also rescaling the texture to powers of 2 multiple
times...)
Can osgUtil::Optimizer somehow recognize identical texture file names
and make the entire scene graph use the same texture handles?
Christian
