3Dfx Glide device driver
Requirements:
-------------
A Voodoo-based videocard/accelerator
DOS (with DJGPP), Windows9x/2k (with MinGW), Linux
Glide3x library for your OS
http://sourceforge.net/projects/glide/
How to compile:
---------------
DJGPP:
Place the Glide3 SDK in the top Mesa directory:
$(MESA)/glide3/include/
3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
$(MESA)/glide3/lib/
libgld3x.a, libgld3i.a, glide3x.dxe
Type:
make -f Makefile.DJ X86=1 FX=1
Look into the makefile for further information.
MinGW:
Place the Glide3 SDK in the top Mesa directory:
$(MESA)/glide3/include/
3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
$(MESA)/glide3/lib/
libglide3x.a, glide3x.dll
Type:
make -f Makefile.mgw X86=1 FX=1
Look into the makefile for further information.
Linux:
Place the Glide3 SDK in /usr/local/glide
/usr/local/glide/include/
3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
/usr/local/glide/lib/
libglide3x.a, libglide3x.so
Type:
make linux-glide
or
make linux-x86-glide
Compilation defines:
--------------------
FX_DEBUG
enable driver debug code
FX_TRAP_GLIDE
enable Glide trace code
FX_PACKEDCOLOR
use packed color in vertex structure
FX_TC_NAPALM
map GL_COMPRESSED_RGB[A] to FXT1. Works with VSA100-based cards only.
FX_COMPRESS_S3TC_AS_FXT1_HACK
map S3TC to FXT1
FX_RESCALE_BIG_TEXURES_HACK
fake textures larger than HW can support
(see MESA_FX_MAXLOD environment variable)
Environment variables:
----------------------
The following environment variables affect MesaFX. Those that affect Glide
only, are beyond the scope of this section. Entries that don't have a "Value"
field, can have any value whatsoever
ex: set MESA_FX_IGNORE_CMBEXT=y
"Note" (*) means that the environment variable affects Glide, too; also, if
the var is not found in the environment, it is searched in windoze registry.
"Note" (!) means that the environment variable is not working as expected;
may have undefined effects, might have effects only at Glide level or might
not have any effect whatsoever. Caveat emptor! Those are to be revised soon.
It is recommended to leave the envvars alone, so that Mesa/Glide will run with
default values. Use them only when you experience crashes or strange behavior.

Info for Mesa 4.1
-----------------
The 3dfx Glide driver in Mesa is disabled by default. Not too many people
use this driver anymore and at some point down the road it will be dropped.
To use/enable the Glide driver either do this:
'./configure --with-glide=DIR' Where DIR is the location of Glide, like
/usr/ or /usr/local
OR
'make linux-x86-glide' If using the old-style Makefile system.
The rest of this file hasn't changed since Mesa 3.3. Some of it's out of
date, but some is still valid.
What do you need ?
------------------
- A PC with a 3Dfx Voodoo1/2 Graphics or Voodoo Rush based board
(Pure3D, Monster 3D, R3D, Obsidian, Stingray 128/3D, etc.).
The Quantum3D Obsidian3D-2 X-24 requires some special env. setting
under Linux (more information in the "Useful Glide Environment
Variables");
- 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 3.1 is not
compatible with the Glide 2.x so it doesn't work with the current
version of the driver;
- A compiler supported by the Glide library (Micro$oft VC++ (tested),
Watcom (tested), GCC for Linux (tested), etc.);
- It's nice to have two monitors - one for your normal graphics
card and one for your 3Dfx card. If something goes wrong with
an application using the 3Dfx hardware you can still see your
normal screen in order to recover.
Tested on:
----------
Windows 95 - David Bucciarelli
Windows NT - Henri Fousse
MS-DOS
Linux - Daryll Strauss, Brian Paul, David Bucciarelli
FreeBSD
BeOS - Duncan Wilcox
MacOS - Fazekas Miklos
What is able to do ?
--------------------
- It is able accelerate points, lines and polygon with flat
shading, gouraud shading, Z-buffer, texture mapping, blending, fog and
antialiasing (when possible). There is also the support for rendering
in a window with a slow trick for the Voodoo Graphics (available only
for Linux) and at full speed with the Voodoo Rush chipset.
Under Linux is also possible to switch on-the-fly between the fullscreen
and in-window rendering hack.
There is also the support for using more than one Voodoo Graphics in the
some application/PC (you can create one context for each board and use
multiple video outputs for driving monitors, videoprojectors or HMDs).
The driver is able to fallback to pure software rendering when afeature
isn't supported by the Voodoo hardware (however software rendering is
very slow compared to hardware supported rendering)
How to compile:
---------------
Linux:
------
Here are the basic steps for using the 3Dfx hardware with Mesa
on Linux:
- You'll need the Glide library and headers. Mesa expects:
/usr/local/glide/include/*.h // all the Glide headers
/usr/local/glide/lib/libglide2x.so
If your Glide libraries and headers are in a different directory
you'll have to modify the Mesa-config and mklib.glide files.
- Unpack the MesaLib-3.1.tar.gz and MesaDemos-3.1.tar.gz archives;
- If you're going to use a newer Mesa/Glide driver than v0.27 then
unpack the new driver archive over the Mesa directory.
- In the Mesa-3.1 directory type "make linux-glide"
- Compilation _should_ finish without errors;
- Set your LD_LIBRARY_PATH environment variable so that the
libglide2x.so and Mesa library files can be found. For example:
setenv LD_LIBRARY_PATH "/usr/local/glide/lib:/SOMEDIR/Mesa-3.1/lib"
- You'll have to run Glide-based programs as root or set the suid
bit on executables;
- Try a demo:
cd gdemos
su
setenv MESA_GLX_FX f
./gears (hit ESC to exit)
- You can find the demos especially designed for the Voodoo driver in
in the Mesa-3.1/3Dfx/demos directory (type "make" in order to compile
everything).
MacOS:
------
Check the WEB page at http://valerie.inf.elte.hu/~boga/Mesa.html
MS Windows:
-----------
For the MSVC++:
- The glide2x.lib have to be in the default MSVC++ lib directory;
- The Glide headers have to be in the default MSVC++ include directory;
- You must have the vcvars32.bat script in your PATH;
- Go to the directory Mesa-3.1 and run the mesafx.bat;
- The script will compile everything (Mesa-3.1/lib/OpenGL32.{lib,dll},
Mesa-3.1/lib/GLU32.{lib,dll}, Mesa-3.1/lib/GLUT32.{lib,dll} and
Voodoo demos);
- At the end, you will be in the Mesa-3.1/3Dfx/demos directory;
- Try some demo (fire.exe, teapot.exe, etc.) in order to check if
everything is OK (you can use Alt-Tab or Ctrl-F9 to switch between
the Voodoo screen and the windows desktop);
- Remember to copy the Mesa OpenGL32.dll, GLU32.dll and GLUT32.dll in the
some directory were you run your Mesa based applications.
- I think that you can easy change the Makefile.fx files in order
to work with other kind of compilers;
- To discover how open the 3Dfx screen, read the sources under
the Mesa-3.1/3Dfx/demos directory. You can use the GLUT library or
the Diego Picciani's wgl emulator.
NOTE: the MSVC++ 5.0 optimizer is really buggy. Also if you install the
SP3, you could have some problem (you can disable optimization in order
solve these kind of problems).
Doing more with Mesa & Linux Glide:
-----------------------------------
The MESA_GLX_FX environment variable can be used to coax most
GLX-based programs into using Glide (and the __GLUT library
is GLX-based__).
Full-screen 3Dfx rendering:
---------------------------
1. Set the MESA_GLX_FX variable to "fullscreen":
ksh:
export MESA_GLX_FX = "fullscreen"
csh:
setenv MESA_GLX_FX fullscreen
2. As root, run a GLX-based program (any GLUT demo on Linux).
3. Be careful: once the 3Dfx screen appears you won't be able
to see the GLUT windows on your X display. This can make using
the mouse tricky! One solution is to hook up your 3Dfx card to
a second monitor. If you can do this then set these env vars
first:
setenv SST_VGA_PASS 1
setenv SST_NOSHUTDOWN
or for the Voodoo2:
setenv SSTV2_VGA_PASS 1
setenv SSTV2_NOSHUTDOWN
Rendering into an X window with the help of the Voodoo hardware:
----------------------------------------------------------------
1. Start your X server in 16 bpp mode (XFree86: startx -- -bpp 16)
in order to have the best performance and the best visual
quality. However you can use any visual depth supported by X.
2. Set the following environment variables:
export MESA_GLX_FX="window" # to enable window rendering
export SST_VGA_PASS=1 # to stop video signal switching
export SST_NOSHUTDOWN=1 # to stop video signal switching
OR
setenv MESA_GLX_FX window
setenv SST_VGA_PASS 1
setenv SST_NOSHUTDOWN 1
(the Voodoo2 requires to use "SSTV2_" instead "SST_").
3. As root, try running a GLX-based program
How does it work? We use the 3Dfx hardware to do rendering then
copy the image from the 3Dfx frame buffer into an X window when
the SwapBuffers() function is called. The problem with this
idea is it's slow. The image must be copied from the 3Dfx frame
buffer to main memory then copied into the X window (and when the X
visual depth doesn't match the Voodoo framebufffer bit per pixel, it
is required also a pixel format translation).
NOTE: the in-window rendering feature only works with double-buffering.
On the fly switching between in window rendering and full screen rendering
--------------------------------------------------------------------------
The Mesa 2.6 has introduced the capability of switching
on-the-fly between the fullscreen/fullspeed rendering and the in-window
hack and vice versa. The on-the-fly switching requires a direct support
by the application but it is really easy to add. You have to start
your X server in 16 bpp mode and to add the following lines to your
application:
#if defined(FX) && define(XMESA)
#include
static int fullscreen=1;
#endif
...
/* In the GLUT keyboard event callback */
#if defined(FX) && !define(WIN32)
case ' ':
fullscreen=(!fullscreen);
XMesaSetFXmode(fullscreen ? XMESA_FX_FULLSCREEN : XMESA_FX_WINDOW);
break;
#endif
...
See the 3Dfx/demos/tunnel.c program
for an example. You have to set the -DXMESA flag in the Makefile's COPTS
to enable it.
Rendering into an X window with the X11 software driver:
--------------------------------------------------------
Set the MESA_GLX_FX variable to "disable" your GLX-based program will use
the X11 software driver (the 3Dfx hardware isn't used at all).
Useful Glide Environment Variables:
-----------------------------------
- To disable the 3Dfx logo, set the FX_GLIDE_NO_SPLASH variable.
- To disable video signal switching:
setenv SST_VGA_PASS 1
setenv SST_NOSHUTDOWN
or for the Voodoo2:
setenv SSTV2_VGA_PASS 1
setenv SSTV2_NOSHUTDOWN
- To set the default screen refresh rate:
setenv SST_SCREENREFRESH=75
the supported values are 60, 70, 72, 75, 80, 85, 90, 100, 120.
- To force the Mesa library to swap buffers as fast as possible,
without any vertical blanking synchronization (useful for benchmarks):
setenv FX_GLIDE_SWAPINTERVAL 0
setenv SST_SWAP_EN_WAIT_ON_VIDSYNC 0
- You can slight improve the performances of your Voodoo1 board with
the following env. var.:
setenv SST_FASTMEM 1
setenv SST_PCIRD 1
setenv SST_GRXCLK 57
(don't use this setting with the Quantum3D 100SB or with any other
SLI configuration: it will hang everything !).
The following setting can be used with the Voodoo2:
setenv SSTV2_FASTMEM_RAS_READS=1
setenv SSTV2_FASTPCIRD=1
setenv SSTV2_GRXCLK=95
- The Quantum3D Obsidian3D-2 X-24 requires some special env. setting
in order to work under Linux:
export SSTV2_FT_CLKDEL=5
export SSTV2_TF0_CLKDEL=7
export SSTV2_TF1_CLKDEL=7
export SSTV2_TF2_CLKDEL=7
export SSTV2_SLIM_VIN_CLKDEL=3
export SSTV2_SLIM_VOUT_CLKDEL=2
export SSTV2_SLIS_VIN_CLKDEL=3
export SSTV2_SLIS_VOUT_CLKDEL=2
(Thanks to Phil Ross for this trick).
The Mesa/Voodoo Environment Variables:
--------------------------------------
- Only for Windows/Voodoo Rush users, if you define the
env. var. MESA_WGL_FX:
export MESA_WGL_FX=fullscreen
you will get fullscreen rendering;
- Only for Windows/Voodoo Rush users, if you define the
env. var. MESA_WGL_FX:
export MESA_WGL_FX=window
you will get window rendering (default value);
- Only for Linux users, you can find more informations about
the env. var. MESA_GLX_FX in the "Doing more with Mesa & Linux Glide"
section;
- If you define the env. var. MESA_FX_SWAP_PENDING:
export MESA_FX_SWAP_PENDING=4
you will able to set the maximum number of swapbuffers
commands in the Voodoo FIFO after a swapbuffer (default value: 2);
- If you define the env. var. MESA_FX_INFO:
export MESA_FX_INFO=1
you will get some useful statistic.
- If you define the env. var. MESA_FX_NO_SIGNALS:
export MESA_FX_NO_SIGNALS=1
Mesa/FX will not install atexit() or signal() handlers.
Know BUGS and Problems:
-----------------------
- fog doesn't work in the right way when using the glDepthRange() function;
- Maximum texture size: 256x256 (this is an hardware limit);
- Texture border aren't yet supported;
- A GL_BLEND in a glTexEnv() is not supported (it is an hardware limit);
- Use the glBindTexture extension (standard in OpenGL 1.1) for texture
mapping (the old way: glTexImage inside a display list, download
the texture map each time that you call the display list !!!);
- Stencil buffer and Accumulation buffer are emulated in software (they are not
directly supported by the Hardware);
- Color index mode not implemented (this is an hardware limit);
- Thre is an know bug in the Linux Glide library so the in-window-rendering hack
and any other operations that requires to read the Voodoo frame buffer
(like the accumulation buffer support) doesn't work on Voodoo SLI cards.
- The driver switch to pure software (_slow_) rendering when:
- Stencil enabled;
- Using the Accumulation buffer;
- Blend enabled and blend equation != GL_FUNC_ADD_EXT;
- Color logic operation enabled and color logic operation != GL_COPY;
- Using GL_SEPARATE_SPECULAR_COLOR;
- The four values of glColorMask() aren't the some;
- Texture 1D or 3D enabled;
- Texture function is GL_BLEND;
- Using the Multitexture extension with Voodoo cards with only one TMU;
- Using the Multitexture extension with Voodoo cards with more than
one TMU, and texture function isn't GL_MODULATE;
- Point size is != 1.0 or point params vector != (1.0,0.0,0.0);
- Line width != 1.0 or using stipple lines.
- Using polygon offset or stipple polygons;
NOTE: this is list is not yet complete.
Hints and Special Features:
---------------------------
- Under Linux and with a Voodoo Graphics board, you can use
XMesaSetFXmode(XMESA_FX_FULLSCREEN or XMESA_FX_WINDOW) in order to
switch on the fly between fullscreen rendering and the in-window-rendering
hack.
- The driver is able to use all the texture memory available: 2/4MB on
Voodoo1 boards and 8MB (!) on high-end Voodoo1 and Voodoo2 boards.
- Trilinear filtering is fully supported on Voodoo boards with two TMUs
(high-end Voodoo1 boards and Voodoo2 boards). When only one TMU is
available the driver fallback to bilinear filter also if you ask
for trilinear filtering.
- The Voodoo driver support multiple Voodoo Graphics boards in the
some PC. Using this feature, you can write applications that use
multiple monitors, videoprojectors or HMDs for the output. See
Mesa-3.1/3Dfx/demos/tunnel2.c for an example of how setup one
context for each board.
- The v0.19 introduces a new powerful texture memory manager: the
texture memory is used as a cache of the set of all defined texture
maps. You can now define several MBs of texture maps also with a 2MB
of texture memory (the texture memory manager will do automatically
all the swap out/swap in
texture memory work). The new texture memory manager has also
solved a lot of other bugs/no specs compliance/problems
related to the texture memory usage.
- Use triangles and quads strip: they are a LOT faster than sparse
triangles and quads.
- The Voodoo driver supports the GL_EXT_paletted_texture. it works
only with GL_COLOR_INDEX8_EXT, GL_RGBA palettes and the alpha value
is ignored because this is a limitation of the the current Glide
version and of the Voodoo hardware. See Mesa-3.1/3Dfx/demos/paltex.c for
a demo of this extension.
- The Voodoo driver directly supports 3Dfx Global Palette extension.
It was written for GLQuake and I think that it isn't a good idea
to use this extension for any other purpose (it is a trick). See
Mesa-3.1/3Dfx/demos/glbpaltex.c for a demo of this extension.
- The Voodoo driver chooses the screen resolution according to the
requested window size. If you open a 640x480 window, you will get
a 640x480 screen resolution, if you open a 800x600 window, you
will get a 800x600 screen resolution, etc.
Most GLUT demos support the '-geometry' option, so you can choose
the screen resolution: 'tunnel -geometry 800x600'.
Clearly, you Voodoo board must have enough framebuffer RAM (otherwise
the window creation will fail).
- The glGetString(GL_RENDERER) returns more information
about the hardware configuration: "Mesa Glide
CARD/ FB/
TM/ TMU/"
where: CARD is the card used for the current context,
FB is the number of MB for the framebuffer,
TM is the number of MB for the texture memory,
TMU is the number of TMU. You can try to run
Mesa/demos/glinfo in order to have an example of the output.
Did you find a lot BUGs and problems ? Good, send me an email.
FAQ:
----
For a complete FAQ check the Bernd Kreimeier's Linux 3Dfx HOWTO
available at http://www.gamers.org/dEngine/xf3D (it includes also
a lot of informations not strictly related to Linux, so it can be
useful also if you don't use Linux)
1. What is 3Dfx?
3Dfx Interactive, Inc. is the company which builds the VooDoo 3-D graphics
chipset (and others) used in popular PC cards such as the Diamond Monster 3D
and the Orchid Righteous 3D (more informations at http://www.3dfx.com).
2. What is Glide?
Glide is a "thin" programming interface for the 3Dfx hardware. It was
originally written for Windows/Intel but has been ported to Linux/Intel
by Daryll Strauss.
3Dfx, Inc. should be applauded for allowing the Linux version of Glide
to be written.
You can directly program with the Glide library if you wish. You can
obtain Glide from the "Developer" section of the 3Dfx website: www.3dfx.com
There's a Linux/Glide newsgroup at news://news.3dfx.com/3dfx.glide.linux
3. What is fxmesa?
"fxmesa" is the name of the Mesa device driver for the 3Dfx Glide library.
It was written by David Bucciarelli and others. It works on both Linux
and Windows. Basically, it allows you to write and run OpenGL-style programs
on the 3Dfx hardware.
4. What is GLQuake?
Quake is a very popular game from id software, Inc. See www.idsoftware.com
GLQuake is a version of Quake written for OpenGL. There is now a Linux
version of GLQuake with works with the Mesa/3Dfx/Glide combo.
Here's what you need to run GLQuake on Linux:
PC with 100MHz Pentium or better
a 3Dfx-based card
Mesa 3.1 libraries: libMesaGL.so libMesaGLU.so
Glide 2.4 libraries: libglide2x.so libtexus.so
GLQuake for Linux.
Also, the windows version of GLQuake works fine with the Mesa OpenGL32.dll,
you have only to copy the Mesa-3.1/lib/OpenGL32.dll in the GLQuake directory
in order to test 'MesaQuake'.
5. What is GLUT?
GLUT is Mark Kilgard's OpenGL Utility Toolkit. It provides an API for
writing portable OpenGL programs with support for multiple windows, pop-
up menus, event handling, etc.
Check the Mark's home page for more informations (http://reality.sgi.com/mjk_asd).
Every OpenGL programmer should check out GLUT.
GLUT on Linux uses GLX.
6. What is GLX?
GLX is the OpenGL extension to the X Window System. I defines both a
programming API (glX*() functions) and a network protocol. Mesa implements
an emulation of GLX on Linux. A real GLX implementation would requires
hooks into the X server. The 3Dfx hardware can be used with GLX-based
programs via the MESA_GLX_FX environment variable.
7. Is the Voodoo driver able to use the 4Mb texture memory of
the Pure3D boards ?
Yes, the Voodoo driver v0.20 includes the support for Voodoo
Graphics boards with more than 2Mb of texture memory.
8. Do the Voodoo driver support the Voodoo Rush under Windows ?
Yes, Diego Picciani has developed the support for the Voodoo
Rush but David Bucciarelli has a Pure3D and a Monster3D and Brian Paul
has a Monster3D, so the new versions of the Mesa/Voodoo sometime are
not tested with the Voodoo Rush.
9. Do the Voodoo driver support the Voodoo Rush under Linux ?
No because the Linux Glide doesn't (yet) support the Voodoo Rush.
10. Can I sell my Mesa/Voodoo based software and include
a binary copy of the Mesa in order to make the software
working out of the box ?
Yes.
11. Which is the best make target for compiling the Mesa for
Linux GLQuake ('make linux-glide', 'make linux-386-glide', etc.) ?
'make linux-386-opt-glide' for Voodoo1 and 'make linux-386-opt-V2-glide'
for Voodoo2 boards because it doesn't include the '-fPIC'
option (4-5% faster).
12. Can I use a Mesa compiled with a 'make linux-386-opt-V2-glide'
for my applications/programs/demos ?
Yes, there is only one constrain: you can't run two Mesa applications
at the some time. This isn't a big issue with the today Voodoo Graphics.
