DirectX

[Maarten Bosma]

Hi,

I have started coding the Direct3d 9 dll. It isn't something usable yet, but
only a few kernel calls have to be made to run the first (very simple)
Direct3D program. I have already looked up those functions, but most of them
need some huge structs as parameters.

At the moment I don't have the time to work on it. Maybe one of you would
like to do so. But be warned this is the first time that i am working on an
open source project and my coding style isn't the best.

Hi
One quesitn do you plan to map the graphice drivers directx to user mode
then to d3d9.dll ?
that way the directx for the graphice crad should go.
thuse api that are not support by the graphice card driver should map to
software emulation api

sames goes for ddraw.dll and some other dll files for directx

I am doing it the same way Microsoft does:

The dll, called by the user program, calls functions inside of the win32k
interface like "NtGdiD3DDrawPrimitives2" which map the functions of the
device driver.

But I have just noticed that most of them aren't implemented yet. Someone
will have to do that first.

Just to clarify, Direct3D and DirectDraw have one major difference from OpenGL, 
and that is there is NO software emulation for missing hardware features. So if 
you want to fully emulate Windows then you will not provide software emulation 
as it would break many games that check the hardware caps bits.

Hi Phil
I have talk about what  can take from wine directx and use it in reactos.
the graphice part of directx in wine are base on OpenGL.

1.  The keyboard, mouse, joystick  system in Directx
    Can be port from wine. (dinput.dll / dinput8.dll)
    and I have done port. follow problem exists in my port. mouse buffer
    does not work right as it should. How to dectect the mouse, keyboard
    and joystick need to rewrite in wine code. and the dectition code should
    go back to winehq. we need also write or own joystick code. for geting
the
    joystick works for reactos and windows. The joystick code. I allready
    got some idea how to write it. but have no time.

2. The sound sytem in Directx
     wine directx are not base on opengl and the sound
    driver does not export any directx api. so we can use wine directx sound
    system. I got already dsound working in windows. it need source clean
and
    resych with wine. I did write the patch code in the summer it did take
me
   two month to write it.

3. The network system in Directx
    I have not check how it works in windows or wine

4. The Graphic system in Directx
    Wine Directx are using mesa3d as enginen here.
    but here we need to write all our code self
    I hope Maarten Bosma are sussefull create d3d9.dll for reactos
    he seasm to know how to write this stuff.  He did decsbie
    how the graphice part of directx works.  if we port over any thing here
    from wine it is only for tempary until some have time to write the code.
   for many apps need ddraw.dll from directx it is the main file for the
graphic
   of directx. It take care of memory and other stuff.

5.  Other things in directx
     maby it is some thing more that I have miss here.

Here is little overview, over the things that have to be done (with quotes
form Magnus). DirectX is has 6 components:

1. DirectX Graphics: (d3d*.dl and ddraw.dll)

This is were most of the work has to done.
Firstly the functions in "subsys\win32k\ntddraw\stubs.c" have to be
implemented,
because the dlls relay on them. I'll do this in the X-Mas holidays, if
nobody
else wants to.
Then the work with the dll's can start. i have already started to code
the very very beginning (com stuff and so on, see my first mail).

2. DirectX Audio:

3. DirectPlay:

i havn't either. But i guess the wine implementation is based on socks I
would
be esay to port.

4. DirectInput:

3. DirectShow & DirectSetup:

These two are rather trivial. Think we better concentrate on the others
right now.
