Hi,
if you have problems with multiple lightsources in your scenegraph not
glEnableling/glDisableing correctly this may be a solution for you.
First lets recap the error:

osg::Light* l2 = new osg::Light();

The new depth peeling example also does silhuette rendering.
Maybe that's what you're looking for...

Hi Mike,
I'm running Kubuntu 7.10 right now and OSG works as expected.
My guess is that the new 3d desktop is screwing things up w.r.t the x

Thanks for all your help Gerrick. I'm past my problems setting up the

No problem.
Whenever you create your texture, just set the subloadcallback:

Wasn't this discussed very recently? You might try searching the archives.
One possible solution would be to render the object twice. Once in fill mode
but render in the background color. Only need to render front faces in this
pass. The other rendering must be in wireframe mode, backfaces only,

Hi Santosh,
These isn't a frame management issue, its entirely a database
optimization issue.
If you model does have LOD's then you can use the LODScale to select
low res LOD children than would otherwise be chosen, but this isn't
quite the what you are looking for by the sound of it - rather you

Hi Robert -- I think he wants to specify a target framerate and have the
scene graph automatically adjust so that the target is achieved regardless

No, OSG does not provide any such capability.

Hi David,
thanks a lot for your suggestion. With the svn osg version everything
works fine!
Not finding anything in the archives I did guess that no bugs were around.
I'll switch to osg 2.x as soon as Delta3D guys finish the porting to the
new osg.
Thanks,

I can confirm similar (but slightly different) behaviour.

a brief moment, but then fullscreen returns. This seems to happen only
the first time I press the 'f' key. Nothing happens on any subsequent

Hey guys, I've got a few questions related to getting 3DS models to

still getting no texture (blank, white quad). Can anyone see
