I've been doing OpenGL for a few years, but am struggling under OpenGL ES with all the missing commands (glTexGen at the mo for example). Is there a way of doing all the stuff OpenGL does under OpenGL ES? Is there an online guide somewhere or a book that's recommended to help us learn the differences and how to handle them?
Also, is there a way to projected textures under OpenGL ES? (Obviously without glTexGen etc)?
Any help would be greatly appreciated.
