Hi Dat,
check whether osgdb_jpeg library is present in osg's bin or plugins
directory. If it is present, then ensure that it's accessible by your
application (as a matter of fact, by your operating system's dynamic
linker; good starting point could be copying osgdb_jpeg library into

Sajjad,
Although you refer to Brian's message, I would like to explain what he
meant briefly.
dynamic_cast allows casting both down and up in inheritance hierarchy.
If object's dynamic type isn't Switch, then you cannot cast a Group
pointer to Switch with dynamic cast. That is:

Hi Robert,
although Apple doesn't sell PPC machines anymore, there are hardcore
devs still using PPC. Mach-O binary can have all architectures you
mentioned. Therefore, passing -arch i386 -arch x86_64 and so on should
generate a binary that contains a Mach-O binary for all listed
architecture.

Hi Sergey,
use osg::Quat to rotate your object.
Trans->setAttitude(osg::Quat(osg::DegreesToRadians(rotation_degree),
fX, fY, fZ));
where fX, fY and fZ indicates axis to rotate.
Trans->setAttitude(osg::Quat(osg::DegreesToRadians(rotation_degree),
1.0, 0.0, 0.0));
will rotate object around X axis.
I meant the latter overload. I didn't have access to any osg stuff and
no compiler. Sorry for overload confusion, but it's good that you
found how to use osg::Quat.

std::bad_alloc is thrown when operator new cannot allocate memory,
which indicates there is not enough memory. You may reserve your array

Hi Martin,
ISO 14882:2003 (the C++03) standard doesn't clearly specify how
containers must swap its contents. It's clearly specified in C++0x
drafts. Most implementations simply exchange internal block (pointers)
and capacity, if allocators are the same. Otherwise, each element will
be copied.

I am not on my Mac right now, but I can quickly suggest you to add
osg, osgText, osgIntrospection (and few more) frameworks to your
executable to get you started as quick as possible. I may not recall

Hi Sh Ha,
If I recall correctly, similar use case worked for me on Mac OS X, but
crashed on Windows (Vista). I simply did:
osg::ref_ptr spViewer = new osgViewer::Viewer;
...
return spViewer->run();
I have no access to source code (I am on vacation). I think what you

Hi Dwight,
I don't know whether there is tuturial about CMake but those red lines
indicate some variables that are required/suggested. If you are
familiar with configure scripts on linux/unix, red lines are analogous
to --with-PKG=path_to_dependency or --enable-FEATURE (if I recall

Hi Ugras,
Did you try to run your code in single threaded mode? This could give
you a hint whether problem is a race.
It's difficult to guess what's going on, but did you try to lock mutex
while you read data as well? This might effectively make your program
serial during those phases (which defe

Yes, you can, can't you? Pass your objects to constructor. I wouldn't
