Hey,
I noticed while debugging a deadlock in ossimPlanet that OpenThreads
uses PTHREAD_MUTEX_NORMAL (rather than PTHREAD_MUTEX_RECURSIVE) mutexes.
As a result, a mutex locked more than once from the same thread thread
will block, which is often not the behavior desired. Is this intentional?

I think I could get a good performance boost rendering shadow maps if
I didn't sort anything. Since shadow texels are either on or off with
no medium gray, I shouldn't matter what order in which geometry is
rendered. Is there a way I can completely disable sorting when

Hey Yong,
You can use "osgconv" to scale it down and resave it for future use.
Simply specify "-s SX SY SZ" on the command line. Run "osgconv --help"
to see all the arguments.
Hope this helps,

One of the models in the scene is too big compared with others, so I need to
scale it down. I tried to do it with osgviewer, since I'm not sure about the
syntax.

OpenFlight uses UserData internally to pass material/shader/etc pools to

I have just checked in some changes to DOFTransform so that it only

The osgviewer automatically positions the eye point so that model
