Yay!! No screenshots yet though... any chance :-) > I'm now working on a basic osgViewer for IPhone, should have something basic > the next time i get an hour or so.

You can tweak the compiler options to to compile to minimize size but I kinda doubt this will help too much. In the end the .ive plugin's weakness is that it's not extensible so that it has to include support for all the OSG NodeKit's and all the Nodes in each of them so it effectively pulls in most of the OSG. The .osg plugin is extensible so you only need to pull in the NodeKits you need. Hope is on the horizon for the an extensible binary format side of things - Wang Rui has proposed a new extensible native binary format, so this may well be able to us to spilt the binary support for each NodeKit over the range of classes. It may also be possible for us to selectively disable the build of classes in the core OSG to help keep size down. Such a scheme will complicate the build quite a bit so I much rather avoid this if we can. BTW, how much space do you effectively have on the iPhone? I guess there is runtime as well as download times to consider.
