Hi Alex, The OpenFlight plugin does not support multi-threaded usage, but does have a reentrant mutex to marshal access through it - effectively serializing access to it. There was a point when the OpenFlight plugin didn't yet have this serializing feature. Which version of the OSG are you using? When using the DatabasePager it runs its own background thread for doing the file reading and data prep, there is only currently one thread that it runs, so typically reading from plugins is still still single-threaded. > Oh yea - I am using the plugin in src/osgPlugins/OpenFlight, not the > one in src/osgPlugins/flt. Out of curiosity, why is there two > different plugins for the same file type? OSG-2.0 only has the new OpenFlight plugin, the old flt plugin has been removed. In 1.2 we kept the flt plugin around for cases where the new plugin wasn't quite mature enough. Robert.
