Cool, eh? And of course, if you don’t see the above, recheck all of your code, and feel

free to cheat by just getting the entire project from Apress. Of course it’s missing the

clouds, but those will be handled a little later.

At this stage, a small problem arises as OpenGL ES shows off a slightly uglier side of

things. Examine the lines closely on your emulator or on a non-Retina device. They don’t

look particularly good, do they? Anti-aliasing of lines was something the OpenGL ES

standards committee apparently felt they could leave out, even though it is standard in

the desktop libraries.

Note The simulator can generate anti-aliased lines, but not so when run on real hardware.
