I'm interested in using the new osg formats, a new xml and binary format I
believe. I was wondering if there is any information on using the
new system, Example questions being
What plugins do I need? osgdb_osg? osgdb_serializers_osg?

Fixed it,
So after a bit of thinking I realised that the default buffer must be re
binded at some point so did another search and found 3 calls to
fbo_ext->glBindFramebuffer(GL_FRAMEBUFFER_EXT, 0);
And my earlier hunch was correct that ios' default buffer id is actually 1
so changing to the bel
So I've found the problem with the FBOs and am in look of a solution. The
problem is, is that ios uses framebuffer objects for everything including
the main views rendering. The current setup uses the swapbufferes method to
Display the renderbuffer then ensure the view framebuffer is bound with

Hi,
LispSM works well with directional infinite lights. So I assume you are
using this type of light. With inifinite light objects casting shadows can
be far outside visible area. So the viewing frustum for shadow camera is
usually larger than view frustum of the camera where shadows are cast.
Hi,
I have i think a simple question. If i'm adding new objects on scene and they
are invisible (culled) or partialy invisible, how to force view or camera to
show all objects (whole scene). Is there any simple method?
Thank you!
Cheers,
Robert

Hi Stephan
So a little testing has reveled that when using a framebuffer object a call
to glFrameBufferRenderBuffer is made in FrameBufferAttachment::attach in
FrameBufferObject.cpp (starts line 541). But this is also done in
createFrameBuffer in GraphicsWindowIPhone.mm with the created
_viewFrame
For completeness, i point out this site [1] which allow to convert sketchup
files into 3ds, obj and other formats.
I hope this post can help those who have my own doubts and problems.
Best regards,
Axel

Greetings,
Does anyone know if there is currently an OSG reader for the XML .scene format?
I'm looking for a simple human readable file format for generating a scene, so
if there is a good alternative available for OSG that would be fine as well,
but at the moment .scene is looking good.

Thank you all for your suggestions, since i had so many problems
building/installing collada-dom i decide to convert sketchup model in the 3ds

I had already installed osgBullet to obtain physics... on next coming days i'll
study how to use those libraries :-)

Hi,
looking through the implementation of Thread::setProcessorAffinity in
PThread.c++ I realized that on a NON-SGI platform the method always returns -1
even if pthread_setaffinity_np or sched_setaffinity might have been executed
correctly. Is this intended?

Hi,
Thank you very much in advance for any help!

When I try to compile the example, using mingww gcc 4.4.0, i get the

Hello Martin,
I have try this way, but it doesn't work. I guess the manipulator needs more
information. For example, when I set the manipulator in the viewer via
addEventHandler(), it doesn't work. A manipulator must set with
setCameraManipulator().
Well I don't know much about what you're

Hi Axel,
You can download the collada file in zip format in the same link you show us
:). I know nothing about osgBullet, but I guess if you can't use collada
then you have to convert the model to some structure that
osgBullet/osgAnimation can deal with.
Cheers.

Hi,
as currently there are a lot of other things to do i didnt manage to look into
the details yet.
We set up a simple OSG-Application where we only have our Deformation Code and
a simple viewer. There we discovered the multi-threaded deformation working and
gaining performance on more cpus.
