Do you have an example of how to use this class with an existing

does not
seem to be present anymore. If you have an example related to
osgViewer that
would be great.
osgveviewerSDL and osgviewerGLUT both show how to use
GraphicsWindowEmbedded.
Thanks for the info. I will take a look at these.
Just as a note, while osgViewer offers more "features" than
SceneViewer for
some apps needs those features are not needed and therefore the
simple
interface of SceneView is more than sufficient and provides easy
integration
with other windowing toolkits. Hopefully with
osgViewer::GraphicsWindowEmbedded offers a similar interface with low
computational overhead that does not bring along features that
cause a
performance hit.
There is essentially no overhead in using osgViewer vs SceneView. As
you'll see from the osgviewerSDL and osgviewerGLUT examples it's
actually very straight forward to use.
Another key benefit of using osgViewer over SceneView is that it means
that you can move between using GraphicsWIndowEmbedded style app to
one using the inbuilt GraphicsWindow functionality or GraphicsWindow
window inheritance, you aren't locked into one style of viewer usage.
Finally osgViewer usage is far more supportable by others in the
community. Using SceneView directly means that you can use and abuse
it in ways that we can't second guess. What makes it harder for us
to support is a loss all round, both for you as you won't get the same
quality of support as you'll get using mainstream classes, and for
those attempting to support you as they just be wasting time trying to
help you do stuff that osgViewer already solves.
I understand this point and for the most part we pay for support to
address these issues (because of the points you raise above). As I
pointed out before I really do not have a need for the features you
mention above and therefore have not found it necessary to move to
osgViewer. Anyway, thanks for the pointers to the examples. I will
take a look at these and see what issues might arise in migrating our
application to this interface.
Doug
