So from helpful comments, I believe I know what I'm doing wrong. I am creating a group and adding cameras to the group. in the cameras I have various drawables that I'd like to update with my program. i can't get the camera's children to update and can't find an example that works. for an example of what i'm trying to do, i took the osghud example and created a few geometries on it. i added a callback that should change a scale factor for the triangles that i'm adding and update the text in one of the screens. i tried to versions. one that had the callback on the camera and one that has the callback on one of the geodes. I appreciate any help anyone might be able to give.
