- Notes for the Alpha Windows Mesa Driver
- ---------------------------------------
- By: Mark E. Peterson (markp@ic.mankato.mn.us)
-
- Introduction
- ------------
-
- The Windows Mesa driver enables Mesa to run on all 32 bit incarnations of
- Microsoft Windows. In addition, a Windows version of the TK package (which
- also enables the aux package to function) is also provided.
-
- Both RGB and indexed color models are supported.
-
- I term the Windows functionality as "Alpha" because it has not been tested
- to my satisfaction yet. Please, feel free to contact me regarding this
- driver. I am also a member of the Mesa mailing list and will respond to
- messages there.
-
- Additional Software
- -------------------
-
- In order to compile and run Mesa applications you will need the Microsoft
- WinG libraries. WinG is a free add-on to Windows that enables fast indexed
- mode graphics programming. You can obtain WinG from the WINMM forum on
- Compuserve or ftp.microsoft.com.
-
- If you wish to run Mesa apps on Windows 3.x you will also need to obtain
- Microsofts Win32s extension for Windows. Win32s is freely available many
- places on the Internet and Compuserve.
-
- Compiling Mesa and samples
- --------------------------
-
- The Windows version of Mesa was developed using Symantec C++ 7.0, the
- Symantec projects and makefiles should be included with this distribution.
- To compile Mesa for Symantec C++ open and build winmesa.prj, tk.prj,
- glaux.prj, and winglu.prj all found in the \MESA\WINDOWS directory. These
- projects will build static libraries which are linked in to the various
- demo projects in the same directory.
-
- Several (but not all) of the examples that ship with Mesa have been set up
- and projects are supplied in this distribution. In general compile the
- samples with the same settings as the libraries. Also if a sample is
- animated you may need to insert a call to InvalidateRect (see
- \mesa\demos\bounce.c).
-
- The following #defines are used to compile the Windows version of Mesa.
-
- __WIN32__ - Indicates compilation for 32 bit Windows.
- __SYMANTEC_BUGS - The Symantec compiler appears to dislike files containing
- only a global variable definition. This define gets us
- around this bug. (see dd.c and vb.c)
-
- At various times I have also had Mesa compiled with Borland C++ 4.5. For the
- libraries, use the target expert to set up a WIN32, static library project.
- For the demos use the target expert to set up WIN32 console mode apps.
-
- Windows specific source files in the distribution
- -------------------------------------------------
-
- \mesa\src\wmesa.c
- \mesa\include\gl\wmesa.h
- \mesa\src-tk\tkwndws.c
-
- To Do
- -----
-
- - Optimize the driver.
- - Test
- - Produce release versions of the makefiles
- - Produce the static libs as DLLs (possibly as drop in replacements for the
- NT OpenGL DLLs ???)
- - Set up projects for the rest of the demos.
- - Produce profile statistics vs. the NT implementation of GL.
- - Look into hardware acceleration (e.g. Matrox Impression, Millenium).
