- DirectX 6 Driver for Mesa 3.0
-
-
-This software is distributed under the terms of the GNU Library
-General Public License, see the LICENSE file for details.
-
-
-
-What do you need ?
-------------------
-
- - A PC with a DirectX 6 video driver installed.
-
- - Mesa 3.0
-
- - The 3Dfx Glide library 2.3 or later for your OS (the 2.4 works fine).
- The Voodoo2 requires the Glide library 2.51. The Glide 3.0 is not
- compatible with the Glide 2.x so it doesn't work with the current
- version of the driver;
-
- - Visual C++ 5.0 is only compiler test but others should be ok with
- changes to the makefiles (CFLAGS/LFLAGS).
-
- - DirectX 6 SDK (was a MS download but not sure if still available).
-
- - SoftIce or another debugger that will get DPF's is nice.
-
-
-Tested on:
-----------
- Windows 95
- Windows 98
- Windows NT 5.0 (beta 2)
-
-
-What is able to do ?
---------------------
-
- - the driver will try and use DirectX to rasterize the OpenGL primitives
- that are sent to the driver. The driver will fall back to SW if the rendering
- context is too big. The fallback to SW still uses DirectDraw. If the driver
- fails to support and operation (accum, stencil, etc) then it will try and get
- Mesa to render it in SW. DirectX 6 features that are unsupported by the
- installed DirectX 6 driver will be mapped to some other best fit feature.
-
-
-How to compile:
----------------
-
- These instructions assume you have Visual C++ installed.
-
- You might need to increase you enviroment space. You can do this by
- adding the following statement to you config.sys.
-
- shell=C:\COMMAND.COM C:\ /p /e:8198
-
- Next setup you compiler enviroment by running vcvars32.bat in the Visual C++
- 'bin' directoy.
-
- c:\DevStudio\VC\bin\vcvars32.bat
-
- Modify the D3D makefile to point at your SDK install. Example has the SDK
- installed on my 'f' drive in the root.
-
- file: \Mesa-3.0\src\makefile.d3d
-
- SDKROOT=f:\mssdk
-
- Now you can simply make the project. If you look in the makefile you can see
- I have some different targets like 'install'.
-
- nmake /f makefile.d3d
-
-
-FAQ:
-----
-
- 1) I don't think the driver is using my DirectX driver.
-
- This maybe true as the current version will only select the Primary D3D driver
- installed. If you 3D card is the secondary (3dfx) then your out of luck for this
- release.
-
- 2) The driver seems like its not HW accelerated.
-
- If you have a video card with limited memory then you might want to try and
- change your destop resolution to a low setting (640x480x16) so that the 3D part
- of the card has more resources. Remeber the driver can't make the card better...
-
- 3) Nothing works.
-
- Make sure you have a DirectX '6' driver installed. Check you driver docs for this
- info or use the SDK info utilities.
- The final 'dll' is named opengl32.dll and is either in the same directory as the
- OpenGL program or in your system directory (x:\windows\system or x:\winnt\system32).
- Check your destop resolution. Most DirectX 6 drivers will only support 16bit and
- 32bit color depth. To find out for sure you can check the DirectX Info Viewer in
- the SDK.
-
-
- 4) Rendering doesn't look right.
-
- Sometimes this is because the card doesn't support a feature that that is required.
- This is usually due to unsupported alpha functions (test/blend) or texture mapping.
- Some cards suffer from too small of an alpha channel. The driver does its best to
- fallback on unsupported features. This is not to say the driver may not have a bug(s).
-
- 5) Textures look bad.
-
- No mipmapping in this release.
