Perhaps you can fork the repository on github and commit your changes to your repository and send the changeset to me via github, I think this is called pull-request on github, then I can review your changes and merge them, cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I think your'e right on this one, once i started thinking about it it got way to complicated. Adding a scale factor to the window data is the way to go I think. Especially as it turns out you can have decimal scale factors e.g. 1.5. So it's alsmost like a 'my res is full screen' indicator. i'll try do the changes today and send to you to check in to the git.

Another approach would be to use the WindowData-class to transport the scale-factor to the view-creation code. I went this route to disable the autorotation of the view. I think this is cleaner than adding a "virtual" screen, which gets complicated, as the iPhone supports IMHO external displays or an new iPad with "retina"-display gets available. Perhaps we can query the scale-factor and apply it to the view when not specified otherwise. Unfortunately I don't have a device with retina display, so can't do any tests. just me 2 cents, cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
