Developing a 3D accelerated shell for ReactOS

[iPick12]

Hi!
I am interested in developing a user32 (reactos/win32ss/user/user32/) version, that would be based on DirectX (/reactos/win32ss/reactx/) instead of GDI.
So, I would like a diagram, or a flowchart, or something that could explain quickly, how are windows drawn and what functions are invloved.
Also, I'd like to know if anyone has already tried this or if somebody is on it right now!

Is it gonna use more RAM or Graphics Card?

ReactOS's DirectX components are mostly not-implemented and thus also non-existing, with the exception of whatever functionality Wine provides (software-rendered instead of hardware acceleration?).
If you want to create such a shell it might be worthwile creating/developing your application and see how it runs on Wine under Linux before trying it on ReactOS.
Alternatively, try/develop it on Windows before switching to ReactOS.

If I were you, I would use OpenGL for acceleration directly. We have D3D8/9 wrappers from wine which would just translate it to HW accelerated OpenGL (if existant), too. Otherwise you will have a Mesa3D build

Thanks for your help. Is Mesa3D slower than OpenGL?
Also, as I posted on my previous thread,
can someone tell me where can I find documentation of the ReactOS window manager,
or the Windows NT windows API architecture?
