Hi Robert,

that the databasePager is loading the pagedLOD.
In Java, there are no logs about any loading... Seems that the LOD do

Have you looked at Spatial Reference Model (SRM), a part of Synthetic
Environment Data Representation and Interchange Specification (SEDRIS)? The SRM
has a C++ API that you can use for converting between different Spatial

You could use Drawable::DrawCallback and override the rendering of

Hi J.P,
I found that the GL driver support for properly accelerating the
reading from the GPU memory using PBO to be very sensitive for pixel
format, and if you fell off the past path it would indeed be slower.
It's a while since I implemented osgscreencapture so can't remember
all the details
HI Hartwig,
Your errors seems to be that your \ is concatenating the lines without
any spaces so the two adjacent options can glued together so you get
-d ps_height_16k.tif-v 0.1 which will of course result in the osgdem
not being able to find the required files.

Hi J.P. , Robert,
as far as I remember PBO is indeed slower for formats not natively supported by
the VRAM. On nVidia GPU's it seems that the PBO transfer of GL_BGRA is imho the
fastest one. Yes, it is even faster than GL_RGBA.
I think that has something todo with alignment of the data in the

Congrats on getting the OSG up and running on the iPhone. I'm
currently reviewing your changes, and will probably introduce the
changes bit by bit, with parts requiring a little refactoring along
the way - for these we'll need so to and fro between us to settle upon
final code.

Hello all,
My job is to upgrade all of our applications that use OpenSceneGraph version
0.9.9 to the latest and greatest stable version. Well quite a few caveats come
with this task:
1.) After version .9.9 there was a major overhaul the the core and OSG producer
is no longer used (Unless
Hi Justin,
Porting from OSG-0.9.9 to OSG-2.x is mainly about porting from
osgProducer to osgViewer, which can actually be pretty straight
forward, or hard depending on how level you got with using Producer.
Conceptually and usage wise osgProducer::Viewer and osgViewer::Viewer
are pretty similar
Hi Thomas,
I have another question:
5) You have your own version ReaderWriterImageIO.cpp in:

standard imageio plugin?
Thanks,

Hi Robert,
I have made a simple example based on osghud. Just press the 'a' key to
reproduce the bug, it emulates what happens on a resize in our application, ie
modification of the image content and size of a texture.
With OSG 2.9.5, it works correctly, with OSG 2.9.6 the texture is garbage
Robert,
Thank you very much! This will help out a ton. I'll try doing some Google

Hi Justin,
Another thing you might want to look at is the osgProducer code that
now lives as a separate project on openscenegraph.org. I haven't
touched it for a long time, but it should be possible to get it
compiling against the latest OSG and Producer with a few tweaks.
Producer diverged a
I'm usually careful to differentiate between core OSG -- the scene
graph itself, the data structure for storing your geometry and state --
and what you use for window/event/context management, which is really
orthogonal to the scene graph.

Hi Fabien,
I've just tried your example it works for me under Kubuntu 9.04 + ATI
graphics, the green square changes to blue as soon as I press 'a'. On
the console I also get an Scaling image from (800,800) to (600,600),
which is osg::Texture automatically working to refit the image to the

Paul,
Fair enough. When browsing through many of the tutorials, documentation, forum
posts, etc. I thought I seen a mention of a major overhaul to the core OSG. I
simply took that and went with it. I'll try to be more accurate and precise
with my terminology - my apologies for the confusion.
I have an osg file that is about 50 MB (not huge but not trivial). When
I load it, the model is entirely black, as if you are looking at a
silhouette of it. If I press the 'b' key nothing happens. If I press it
again, suddenly everything looks correct. If I keep hitting 'b', it
toggles between the
