Allen,
Thanks very much! I had seen traffic about the database pager, but I
thought it was an alternate way to load terrain data (more of a lower
level "hands-on" approach). This tells me I glossed over the wrong
material ;-)
Although new to OSG, I am most certainly not new to software

I sent you a personal email Richard with a few suggestions.
What I believe Richard was getting at, is there any global settings that should
be made to the system. What I instantly thought of was this :
osgDB::DatabasePager* pPager =
osgDB::Registry::instance()->getOrCreateDatabasePager();
Occurs on OSG 2.x on FreeBSD 6.2.
Definitely a FreeBSD-specific problem.
Already tried single-threading.

Hi, Brede,
Actually, no. I was just looking for the place to migrate my custom
code that writes the object flags to the comment field of the converted
node. In particular, we are using the daylight, dusk and night flags. I'll
add it in readRecord(), as before. I believe OSG still doesn't pr
Hi Yefei,
If my memory is correct I believe this flag is used by Creator for the
"Calculate shading" operation. Using this flag to enable flat shading
didn't work very well.
Do you have a model that renders incorrectly?

Hello, Brede,
I did an update on OSG yesterday, and noticed that in the OpenFlight
plugin, it used to set the shade model of an object to flat shaded when
the flag FLAT_SHADED was set, but the latest version does not do it
any more. Was this left out by intention?
Thanks,

Hi guys,
I implemented an osgDB::Registry::ReadCallback to catch when an LOD page
gets loaded. Now the issue I have is distinguishing if the node that I
get in readNode() came from an LOD page since the ReadCallback gets
executed for anything that gets loaded as a node.
The only option I see is
Ok, before we get anymore bad blood here let me just say I did not
frame my original question properly, which has lead to a
misunderstanding and elevated blood pressures. I basically got my
answer (and then some), but I did not mean to cause a goading war.

Hi Richard,
You shouldn't have to do any performance tuning with VPB dataset, they
are supposed to built well balanced in the first place. If there is a
problem then its not a general problem but something very specific
about your system and the way you've set things up - from the little

If I set the CullMask of the camera to 0x10 the traversal mask will be

It seems that if the traversalMask gets set to 0x10 it shoul

Sorry for turning this into a troubleshooting thread. Bringing it back to

I hope to be able to test this on Windows soon and give you some feedback on
that front.

Thanks for that. I thought it would be easier to derive from existing zip

Way too little information to be able to know what is up with

Hi Stephane,
The OSG's FBO implementation doesn't yet support anti-aliasing, but it
shouldn't be difficult extension to add support for. I do have this
on my TODO list, just unfortunately quite within grasp as I've been so
swamped with other work.

It will default to 64bit if your OS is 64bit.
