Hi,
I have just updated the 2010 3rd party binaries and have updated the wiki to
point to the new file (

). I have added a README.txt which lists the changes:

Hi,
Using MSYS & MingW on WinXP Pro.
I can get the libraries to compile, and get OSG to compile all the plugins, but
when I try to open a file, I get the 'no data loaded' error.
Thank you!
Cheers,
Samuel

Hello forum,
I have a scene where i am animating the light position using the animation

Now i want to implement the per-pixel lighting to a certain node in the
scene. I need to end the light position
as uniform variable to the vertex shader program.

Hi Aruna,
Are you using ffmpeg to load your videos? Is your video an AVI, MOV or FLV?
Thank you!

The final problem I seem to be having with extending View instead of Viewer is

Actually, it appears this model will not be suitable for the osgfltexport test
suite, as the initial view is an edge-on polygon, so the image compare will
succeed even if the polygon is drawn incorrectly.
However, I've noted that the issue appears to be related to rendering a

Hi Sanat,
I sounds a bit complicated to me.
VPB generates a quad tree paged database for you, I would suggest for
your source of terrain data use the TerrainTile that are loaded at
runtime, and using the quad tree scene graph structure that paged in
at runtime if you want to manage the level of d
Hi Iñaki,
You'll need to include both the osg plugin and the osgText plugin.
What USE_OSGPLUGIN lines are you using right now?

I can't test your code right now because the code I am currently using in a
geometry shader is compiled incorrectly on my machine and I can't make it work!
I have reported a bug to AMD that they are currently investigating.
I will test the code in the future, I just don't exactly know when. I'll
I'm attempting to call Thread::setProcessorAffinity() by doing the following:
Code:
mThread->setProcessorAffinity(cpuNum);
In looking at this code, I'm seeing the affinity is only set by this call if
the following condition is true:
Code:
if (pd->isRunning && Thread::CurrentThread()==this)
I am not surprised this message has been left unanswered as it is not rocket
science to release shader objects.
It might be a bug, or at least a very unfortunate behavior, in the AMD Catalyst
drivers, see:

Hello Alexander,
Is there a possibility to create a geometrical object bei subtracting an
object(or drawable or...) from another?

I am working with LiDAR data. Its a huge data containing the information of X,

I want to know how can I identify
@Robert:
I have read up on a bit of the techniques people have tries to use for this:

Represent the terrain as Blocks. Blocks are the basic storage unit for data and
are used to transfer data from the CPU to GPU for processing.

Hi,
sorry that my answer took so long. I had a lot of other things to do the last
weeks.
I posted an issue at the OSG FLT export project issue page:

Yes, I want to do the modifications at runtime. It is mainly due to interaction
of actors with the terrain causing deformations.
My idea is also to modify the height value in the terrain grid and this height
value will constantly be updated and rendered to show a sort of real-time

Hi all,
When I save my scene to a "file.osg", osgText::Text nodes are not saved
into the file. This happens only when I statically link OSG to my
application, when I use the DLLs everything is OK. So I suppose that the
"Plugins osgText" is not being registered/linked to my app. I have tried

Thanks J-S,
I had the same idea myself but unfortunately OpenGL drivers don't take
thread or process priority into account. I made a simple test app that just
renders thousands of quads, ran two instances simultaneously, set the
process priority of one to high, and the priority of the other to idle

There is no constructional geometry code like you are asking for in
