Hi Chris,
Why are you trying to override the default behavior in the first place?
Simply set the node's matrices by adding a transform node with absolute
reference frame as parent/modify the camera's projection matrix. If you
need it per graphics context you might consider using different scene
graphs per camera(thus context).
Rather than asking for on obscure seeming approach, you might get more
ideas by describing what you are after.

Hi,
What is the proper way to set the view/projection matrix to a uniform yourself?
I've found that trying to deal with the osg_ built-in uniforms which do all
sorts of renaming etc is unreliable and would like to be able to just set
everything myself manually.
At the moment I'm setting the view / projection matrix uniforms within the
camera's initialdrawcallback, but I'm not sure if this is the right way to do
it that will ensure the uniform value will only be used within that camera and
not within other cameras (since it needs to work across multiple screens and
render stages).
Is there some code within OSG that ensures that a uniform assigned to a camera
will only apply to the graphics context for the thread that set it?
Thank you!
Cheers,
Chris
