It looks like OSG just released a new version (that was pretty quick).
See: http://www.openscenegraph.org/osgwiki/pmwiki.php/News/News#osg_1.2
The main things they have added are:
* Support for Windows 64 build
* Support for IBM's AIX operating system, bringing the total number
of supported operating systems to 8.
* COLLADA plugin support for both the reading and writing of COLLADA
1.4 .dae files.
* Processor affinity support allowing application to lock cull-draw
and database processes to specific processors, thereby avoiding
cache coherency problems associated with processes moving from
processor to processor.
* A Texture Atlas builder has been added to the database
optimization classes, allowing either manual or automated setting
up of texture atlas. Using texture atlas can improve performance
by reducing the number of state changes required to render a
scene, and by allowing databases to batched in large groups of
geometry, in a form that better suits modern graphics architectures.
* GPU timing stats have been added to the viewer class, provided the
time taken to process allow drawing operations down on the GPU for
the previous frame. Coupled with the existing timing of CPU
update, cull and draw dispatch the stats reporting now provides
the end user with a clearer idea of whether their application is
CPU or GPU limited and server as a better guide to performance
optimization work
Is anyone interested in porting any of that over to OpenSG? I know I
would be interested in have the Texture Atlas, GPU timing information,
and processor affinity. Is there anything we can learn from their
COLLADA loader and writer? It also sounds like they have
multi-processor rendering which we have coming in OpenSG 2.0, but is
there any way to get that into 1.8?
