Perhaps a nice tip: I found it convenient to enable building the universal

Ulrich,
I believe what you say would work (I have not used shaders with osg at all) -
after searching a bit I was unable to find any good examples - how difficult is
that to implement?
Any help would be appreciated here as well :-)
Thanks,

Hi all -- Does anyone know of a state tracking NodeVisitor, either in core OSG

What you do is play with 2 PBOs. Have a look at the diagram here, in the figure

I typically build with Makefile support, but the XCode generator works as well.
Interesting, so I could make CMake generate makefiles, build OSG that
way, and then inspect the makefiles to find out how to do the same thing

Thanks a lot for your help,

Hi Stephan,
Somehow I knew you would answer :-)
freetype is part of the system and should be 32+64bit.
I'd stick with one backend, namely Cocoa, as it supports 32bit and 64bit
out of the box. The carbon backend is deprecated.
ImageIO supports 32 and 64bit.
OK, seems I'm set. For OSG at least.

Hi Jean-Sébastien,
you can build universal binaries with intel 32 and 64 bit support, just
change CMAKE_OSX_ARCHITECTURES to "i386;x86_64".
Of course you have to make sure that all your third-party libraries are
"universal" and contain the architectures you intend to support.

Jean,
I build universal binaries on OSX just fine. I run Snow Leopard (10.6.x), but
I generate code compatible with 10.5. I build all of my 3rd party libraries
manually, which is sometimes a pain as some packages are not friendly to
universal builds. In those cases, the configure script bomb

Thanks Mourad,
That solves my problem. I saw this method used inside the code but did not
notice it is static so I thought it can be used only when we know the uniform
ptr.
Do you think it makes sense to add following extra method to PerContextProgram ?

This change was introduced in rev 11952. This new static function in
