Introduction
|
|
------------
|
|
|
|
This file contains information about Wine's implementation of
|
|
Direct3D.
|
|
|
|
The current version has been tested using Mesa. For optimal
|
|
performances, you need at least Mesa 3.1 beta 2.
|
|
|
|
|
|
Where to find Mesa :
|
|
--------------------
|
|
|
|
The home of Mesa should soon be http://www.mesa3d.org/
|
|
|
|
For precompiled RPMs, use AltaVista or FTPSearch, but I prefer to 'Use
|
|
the Source' :-)
|
|
|
|
WARNING : if you experience crashes in D3DTexture2_Load, see file
|
|
d3dtexture.c for a 'cure'. You could also patch your version of Mesa
|
|
or get version 3.1 beta 2 or the latest CVS version.
|
|
|
|
How to configure Mesa :
|
|
-----------------------
|
|
|
|
For Mesa version > 3.1b2, you can configure the Voodoo driver to not
|
|
override the signal handlers (something that Wine does really not
|
|
like).
|
|
|
|
For that add the following lines to the /etc/mesa.conf file :
|
|
|
|
;; Profile for Wine
|
|
(config-mesa wine
|
|
((fx-catch-signals false)))
|
|
|
|
And do a 'export MESA_CONFIG=wine' before starting Wine.
|
|
|
|
Code structure
|
|
--------------
|
|
|
|
TODO (well, once the code will be put in the dll/ddraw directory)
|
|
|
|
Status
|
|
------
|
|
|
|
Some programs with which I tested the code :
|
|
|
|
* BOIDS.EXE (DX5.0) : works great. Only thing missing is the
|
|
texturing and transparency on the spinning gobes. Lighting seems to
|
|
be a bit different than the Real One.
|
|
|
|
* TWIST.EXE (DX3.0) : vertex transformation works as it
|
|
should. Texturing and lighting still off.
|
|
|
|
* Tomb Raider II (DX5.0) : works perfectly (but slowly) in software
|
|
mode. All the calls needed to make TR2 work have been written. In
|
|
3D accelerated mode with a Voodoo board, it works fine except for
|
|
color keying (no transparent textures :/). This is being
|
|
investigated with the Mesa authors.
|
|
|
|
* Jedi Knight Demo (DX3.0) : works well with the old OSMesa
|
|
code. Works for the new GLX code but without the 'head-up' display
|
|
(because it is blitted directly on the frame-buffer :/)
|
|
|
|
* Shadow of the Empire demo (DX3.0) : displays a mangled intro screen
|
|
(only blue squares on the screen)
|
|
|
|
* Forsaken Demo : starts to work. Texturing is missing and it is
|
|
really really slow.
|
|
|
|
* Grim Fandango (DX 3.0 !!) : works in DDraw mode. Some problems in
|
|
D3D mode as it does direct Z Buffer writing.
|
|
|
|
TODO
|
|
----
|
|
* work on optimizing Execute Buffers (i.e. Direct3D 3.0)
|
|
* restructuration of all the DDRAW.DLL (put that in the dll
|
|
directory, better separation of 'drivers, ...)
|
|
* start looking into DirectX 6.0
|
|
* inquire on Mesa / XFree86 mailing lists about direct access to
|
|
display hardware (for games such as Tomb Raider II that displays
|
|
vertices that are already in screen coordinates)
|
|
* look into thread safeness...
