- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-
-
-Description:
-~~~~~~~~~~~~
-
-Well, guess what... this is the DOS port of Mesa 5.0.1, for DJGPP fans... Whoa!
-The driver has its origins in ddsample.c, written by Brian Paul and found by me
-in Mesa 3.4.2.
-
-
-
-Legal:
-~~~~~~
-
-Mesa copyright applies, provided this package is used within Mesa. For anything
-else, see GPL.
-
-
-
-Installation:
-~~~~~~~~~~~~~
-
-Unzip and type:
-
- make -f Makefile.DJ [OPTIONS...]
-
-Available options:
-
- Environment variables:
- CPU optimize for the given processor.
- default = k6
- GLU=[src|si] specify GLU directory; can be `src' (src-glu = Mesa)
- or `si' (si-glu = SGI's GLU -- requires GNU/C++).
- default = src
- GLIDE path to Glide3 SDK include files; used with FX.
- default = $(TOP)/include/glide3
- FX=1 build for 3dfx Glide3. Note that this disables
- compilation of most DMesa code and requires fxMesa.
- As a consequence, you'll need the DJGPP Glide3
- library to build any application.
- default = no
- MATROX=1 build for Matrox Millennium I (MGA2064W) cards.
- This is experimental and not intensively tested.
- default = no
- HAVE_X86=1 optimize for i386.
- default = no
- HAVE_MMX=1 allow MMX specializations, provided your assembler
- supports MMX instruction set. However, the true CPU
- capabilities are checked at run-time to avoid crashes.
- default = no
- HAVE_SSE=1 (see HAVE_MMX)
- default = no
- HAVE_3DNOW=1 (see HAVE_MMX)
- default = no
-
- Targets:
- all: build everything
- libgl: build GL
- libglu: build GLU
- libglut: build GLUT
- clean: remove object files
- realclean: remove all generated files
-
-
-
-Tested on:
- CPU: K6-2 (CXT) @500(412.5) MHz
- Mainboard: ViA Apollo VP2/97 w/ 128 MB SDRAM
- Video card: PowerColor EvilKing3 (Voodoo3 3000 PCI) w/ 16 MB SDRAM
- DJGPP: djdev 2.04 + gcc v3.2.2 + make v3.79.1
- OS: DOS and Win9x
-
-
-
-FAQ:
-~~~~
-
-1. Compilation
-
- Q) I tried to run `make' and it exits because `gcc' complains it cannot find
- some stupid file.
- A) You need LFN support.
- A) When compiling for Glide (FX=1), pay attention to Glide path.
-
- Q) Libraries built OK, but linker complains about `vsnprintf' every time I
- compile some demo.
- A) Upgrade to DJGPP 2.04.
- A) Add `vsnprintf.c' to the CORE_SOURCES in `src/Makefile.DJ' (untested!).
- A) The following hack should be safe in 90% of the cases, but if anything
- goes wrong, don't come back to me crying. Anyway, patch `src/imports.c'
- with the following line:
- #define vsnprintf(buf, max, fmt, arg) vsprintf(buf, fmt, arg)
-
- Q) `make' complains about DXE3 or something, yet it builds the libraries.
- A) DXE3 refers to the DJGPP dynamic modules. You'll need either the latest
- DJGPP distro, or download the separate package from my web page. Read the
- DXE3 documentation on how to use them. Hint: build your export object
- file; then link it with your application. For example:
- dxe3res -o dxe3tbl.c gl.dxe glu.dxe glut.dxe
- gcc -o dxe3tbl.o -c dxe3tbl.c
- gcc -o OUT.exe dxe3tbl.o IN.c -liglut -liglu -ligl -ldl
-
-2. Using Mesa for DJGPP
-
- Q) DMesa is so SLOOOW! The Win32 OpenGL performs so much better...
- A) Is that a question? If you have a Voodoo3/Banshee card, you're lucky (the
- Glide port is on my web page). If you have a Matrox Millennium I card,
- you just MIGHT be lucky... If you haven't, sorry; everything is done in
- software. Suggestions?
-
- Q) I tried to set refresh rate w/ DMesa, but without success.
- A) Refresh rate control works only for VESA 3.0. If you were compiling for
- Glide, see Glide info. If not, sorry!
-
- Q) I made a simple application and it does nothing. It exits right away. Not
- even a blank screen.
- A) The pure software drivers (VESA/VGA) support only double-buffered modes.
- A) Another weird "feature" is that buffer width must be multiple of 8 (I'm a
- lazy programmer and I found that the easiest way to keep buffer handling
- at peak performance ;-).
-
- Q) My demo doesn't display text. I know I used the GLUT font routines!
- A) Then you probably use GLUT as a DXE. Well, there is no direct access to
- variables due to the way DXE works. Read the documentation. The author of
- GLUT took this into account for _WIN32 DLL's only; I don't want to modify
- his headers. The only workaround is to link GLUT the old way :-(
-
- Q) The GLUT is incomplete.
- A) See below.
-
-
-
-libGLUT (the toolkit):
-~~~~~~~~~~~~~~~~~~~~~~
-
-Well, this "skeletal" GLUT implementation was taken from AllegGL project and
-heavily changed. Thanks should go to Bernhard Tschirren, Mark Kilgard, Brian
-Paul and probably others (or probably not ;-). GLUT functionality will be
-extended only on an "as needed" basis.
-
-GLUT talks to hardware via PC_HW package which was put together from various
-pieces I wrote long time ago. It consists from the keyboard, mouse and timer
-drivers.
-
-My keyboard driver used only scancodes; as GLUT requires ASCII values for keys,
-I borrowed the translation tables (and maybe more) from Allegro -- many thanks
-to Shawn Hargreaves et co. Ctrl-Alt-Del (plus Ctrl-Alt-End, for Windows users)
-will shut down the GLUT engine unconditionally: it will raise SIGINT, which in
-turn will (hopefully) call the destructors, thus cleaning up your/my mess ;-)
-NB: since the DJGPP guys ensured signal handlers won't go beyond program's
-space (and since dynamic modules shall) the SIGINT can't be hooked (well, it
-can, but it is useless), therefore you must live with the 'Exiting due to
-signal SIGINT' message...
-
-The mouse driver is far from complete (lack of drawing, etc), but is enough to
-make almost all the demos work. Supports the CuteMouse WheelAPI.
-
-The timer is pretty versatile for it supports multiple timers with different
-frequencies. While not being the most accurate timer in the known universe, I
-think it's OK. Take this example: you have timer A with a very high rate, and
-then you have timer B with very low rate compared to A; now, A ticks OK, but
-timer B will probably loose precision!
-
-As an addition, stdout and stderr are redirected and dumped upon exit. This
-means that `printf' can be safely called during graphics. A bit of a hack, I
-know, because all messages come in bulk, but I think it's better than nothing.
-"Borrowed" from LIBRHUTI (Robert Hoehne).
-
-Window creating defaults: 300x300x16 at (0,0), 16-bit depth, 16-bit accum,
-8-bit stencil. However, the video mode is chosen in such a way that first
-window will fit. If you need high resolution with small windows, set initial
-position far to the right (or way down); then you can move them back to any
-position right before the main loop.
-
-The following environment variables can customize GLUT behaviour:
- DMESA_GLUT_REFRESH - set vertical screen refresh rate (VESA3)
- DMESA_GLUT_BPP - set default bits per pixel (VGA needs 8)
- GLUT_FPS - print frames/second statistics to stderr
-
-

- * Triangle Rasterizer Template
- *
- * This file is #include'd to generate custom triangle rasterizers.
- *
- * The following macros may be defined to indicate what auxillary information
- * must be interplated across the triangle:
- * INTERP_Z - if defined, interpolate Z values
- * INTERP_RGB - if defined, interpolate RGB values
- *
- * TAG - function name
- * CULL - enable culling for: 0=no, 1=back, -1=front
- *
- * SETUP_CODE - to be executed once per triangle (usually HW init)
- *
- * For flatshaded primitives, the provoking vertex is the final one.
- * This code was designed for the origin to be in the upper-left corner.
- *
- * Inspired by triangle rasterizer code written by Brian Paul.
