So far just threads and osg, thought I'd go for a minimum needed to get a
proof of concept first. Although Util is probably a good idea. So far the
only problem was that the path for the gl header was a little different on
IPhone and just had to config out display lists etc.
osgDB could be a funny one, I'll see what happens but by default the IPhone
sdk doesn't present any obvious ways (wizards) for creating dynamic libs.
May have to look into if Apple even allows the run time loading of libs.

I have a glES context so sounds like sceneView is my best bet.

Yes IPhone uses cocoa and Objective C which at the momnet I rather suck at
(jump to c++ at first chance). It does use views and windows although at the
mo my window is created in the interface editor. I think the cocoa viewer
should be a pretty good start point for an iphoneViewer.
I'm hoping to get a test scene rendering tonight and then should get a
chance to try a stab at an iphone implementation of Viewer. Leaving plugins
as the big maybe :)
