Hi all
I am trying to use osgDB::Registry cache to avoid loading the same models
multiple times.
Caching works ok, reduces the memory usage as expected.
I enable caching with :
Code:
osgDB::Options* opt = osgDB::Registry::instance()->getOptions();
if (opt == NULL)
{
opt = new osgDB::Options();
}
opt->setObjectCacheHint(osgDB::Options::CACHE_ALL);
osgDB::Registry::instance()->setOptions(opt);
I read an ive file with :
Code:
osg::ref_ptr<osg::Node> node = osgDB::readNodeFile(f);
(a quick question : if i enable caching globally like the above chunk of code,
do i have to pass options parameter to the overloaded readNodeFile function ?)
But whenever i read an ive file with switch ability more than once; a switching
action during runtime alters all of the models.
For eg. when i load two traffic lights, the second one is retrieved from cache.
And if i change the switch on any of them, the other one gets affected too!
Any hints guys ?
PS : I was trying to read osgCal animated meshes in my OSG code a while ago.
And i implemented a map to not to load the same animated mesh from file more
than once. But at the time, i had the same problem : when an animation was
triggered, all of the animated mesh instances got affected. I overcame this
problem by caching osgCal::CoreModel instead of osgCal::Model
Thanks in advance
