Hi John,
Modern hardware generally is best driven with a modest number of quite
large batches of geometry, rather than a large number of small batches
of geometry. Exactly where the balance will lie with your database
will depend upon your hardware and drivers, and also how efficiently

Might I suggest that a more general approach to this be implemented in
osgconv?
osgconv is a convenience tool that covers a few of the types of pre
processing that you might want to apply to database. It's not meant
to be an all encompassing tool for all types of pre processing on all
Hi all, I have a scene graph containing a switch node (osg::Switch) having 4
children.
What would be the best way to render this scene graph in 4 different
views/viewports, with each child (attached under the osg::Switch) rendered in
its own view? Thanks!

Thanks for the response.
Then, how do you associate the TextureArray with a texture unit number (which
is then used in the setTextureAttribute() call)?

Is it possible for a slave camera to have different near and far clipping

more complicated than changing the angle of view or adding a shear to the view
