While you probably *should* be doing this yourself (especially in the post-immediate-mode era), legacy OpenGL will actually handle this for you too. Look into the gluProject/gluUnProject functions if you are interested.
That's true -- I'd forgotten about those. However, there are often other reasons for doing it yourself as well. For example, doing physics calculations in a game, or manipulating objects in a drawing program. In any case, it's good to understand what's going on, even if you use libraries that handle most of it for you. -- Greg -- You received this message because you are subscribed to the Google Groups "pyglet-users" group.
