Definately. Those frameworks are outstanding. Especially when you are new
to this DirectX stuff - it saves you from a lot of headaches when it come to
detail.
Especially
Direct3D framework has so many cool things already implanted.
Texture generation, fullscreen/window switch, basic WinApi stuff in WindowProc
and of course the basic 3D functions.
I really tend to start spending some time with DirectX - but on the other hand
I have too much other things to do - which is really a shame. If I had more
time I would definately start coding upon Jim's frameworks.
