Hi J.P.
I'm still knee deep in merging submissions so can't yet go off
reviewing user code. In principle it is possible to mange open and
closing viewers. I can point you in the right direction but have to
let you get on with it otherwise.
I understand, I'll try search for cleanup code, just not sure where to
start.
Anyone else?

Hi J.P,
The typical problem is that the scene graph has been set up to unref
texture images after apply so when it comes to reloading the texture
images there aren't the to download.
should this still happen when I'm completely reloading a scene after the
viewer and scene have been deleted completely?
It seems that OSG thinks there is still a valid texture it can use after
I've deleted the scene and CompositeViewer.
Running the attached e.g.:
./test cow.osg
Constructing PixelBufferObject for image=0x9547928
_maxTexturePoolSize=0
_maxBufferObjectPoolSize=0
Created new TextureObject, _numOfTextureObjects 1
Created new TextureObject, _numOfTextureObjects 1
now I click the X on the window and the app deletes the scene and viewer and
creates them anew:
_maxTexturePoolSize=0
_maxBufferObjectPoolSize=0
Reusing orhpahned TextureObject, _numOfTextureObjects=1
Warning: detected OpenGL error 'invalid value' after RenderBin::draw(,)
Reusing orhpahned TextureObject, _numOfTextureObjects=1
Warning: detected OpenGL error 'invalid value' after RenderBin::draw(,)
So it tries to reuse something that's not there? How can I convince OSG to
drop all caches/buffers/GL objects?

Hi all,
I've run into the classic "missing textures" problem when stopping and
restarting a compositeviewer multiple times in the same app. From
previous
threads on this problem it seems to be context cleanup/GL object cleanup
that does not get done properly, but I'm just using the normal
CompositeViewer and not messing with contexts/windows/sceneviews myself,
so
I thought the cleanup would be handled correctly.
Attached a very slightly modified compositeviewer example. All it does is
create/destruct the compositeviewer 5 times. When the viewer is created
for
the second time, all my textures are gone (just run without any
arguments).
Can anyone confirm the missing textures? Any hints as to what else needs
to
be done to make sure everything is cleared/flushed correctly?
thanks
