Hi,
I found this sceniX forum post
http://developer.nvidia.com/forums/index.php?showtopic=5357&pid=16495&mode=threaded&start=
and wonder if this is akin to the osg approach.
If so, how can osg be extended in the right way so that currently not supported
GL3 features are accessible ?
Thank you
Hi, Roman
osg arrays, as most osg objects can be stored with osg::ref_ptr. You cant
delete Vec3Array yourself, because it have protected destructor. If you store
it with ref_ptr it will be destroyed when no more references left.
Cheers,
Sergey.

Polygons are known to be of less performance and add some other
oddities, because rendering of polygons can't be done with the usual
algorithms. Therefore the

Hi, Peter
There are some similarities with osg in that regard, osg caches current state
to avoid redundant state changes and if you make gl calls yourself you should
tell osg state that you changed something, look into osg::State docs about
that. Most gl changes in osg done through statesets wit

Hi Grahame,
Might the binary compatibility been broken between g++ 4.4.3 and 4.5.2?
In terms of a different g++ version causing problems directly in the
OSG code base, I'd suspect a bug in the compiler before a bug in the
OSG, as the OSG is used with a wide range of compilers without showing

Hi,
I think the return from the handler determines if the event was handled
or not and if it should be passed further down the list of handlers.
Check what the return is from the imagehandler and change it to see if
it has the effect you are looking for.

That would swap, but also invert some axis (det C = -1). Not sure if
