GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS

This is the complete source code for winquake, glquake, quakeworld, and
glquakeworld.
The projects have been tested with visual C++ 6.0, but masm is also required
to build the assembly language files. It is possible to change a #define and
build with only C code, but the software rendering versions lose almost half
its speed. The OpenGL versions will not be effected very much. The
gas2masm tool was created to allow us to use the same source for the dos,
linux, and windows versions, but I don't really recommend anyone mess
with the asm code.
The original dos version of Quake should also be buildable from these
sources, but we didn't bother trying.
The code is all licensed under the terms of the GPL (gnu public license).
You should read the entire license, but the gist of it is that you can do
anything you want with the code, including sell your new version. The catch
is that if you distribute new binary versions, you are required to make the
entire source code available for free to everyone.
Our previous code releases have been under licenses that preclude
commercial exploitation, but have no clause forcing sharing of source code.
There have been some unfortunate losses to the community as a result of
mod teams keeping their sources closed (and sometimes losing them). If
you are going to publicly release modified versions of this code, you must
also make source code available. I would encourage teams to even go a step
farther and investigate using public CVS servers for development where
possible.
The primary intent of this release is for entertainment and educational
purposes, but the GPL does allow commercial exploitation if you obey the
full license. If you want to do something commercial and you just can't bear
to have your source changes released, we could still negotiate a separate
license agreement (for $$$), but I would encourage you to just live with the
GPL.
All of the Quake data files remain copyrighted and licensed under the
original terms, so you cannot redistribute data from the original game, but if
you do a true total conversion, you can create a standalone game based on
this code.
I will see about having the license changed on the shareware episode of
quake to allow it to be duplicated more freely (for linux distributions, for
example), but I can't give a timeframe for it. You can still download one of
the original quake demos and use that data with the code, but there are
restrictions on the redistribution of the demo data.
If you never actually bought a complete version of Quake, you might want
to rummage around in a local software bargain bin for one of the originals,
or perhaps find a copy of the "Quake: the offering" boxed set with both
mission packs.
Thanks to Dave "Zoid" Kirsh and Robert Duffy for doing the grunt work of
building this release.

KEY BUTTONS
Continuous button event tracking is complicated by the fact that two different
input sources (say, mouse button 1 and the control key) can both press the
same button, but the button should only be released when both of the
pressing key have been released.
When a key event issues a button command (+forward, +attack, etc), it appends
its key number as a parameter to the command so it can be matched up with
the release.
state bit 0 is the current state of the key
state bit 1 is edge triggered on the up to down transition
state bit 2 is edge triggered on the down to up transition

/*
cvar_t variables are used to hold scalar or string variables that can be changed or displayed at the console or prog code as well as accessed directly
in C code.
it is sufficient to initialize a cvar_t with just the first two fields, or
you can add a ,true flag for variables that you want saved to the configuration
file when the game is quit:
cvar_t r_draworder = {"r_draworder","1"};
cvar_t scr_screensize = {"screensize","1",true};
Cvars must be registered before use, or they will have a 0 value instead of the float interpretation of the string. Generally, all cvar_t declarations should be registered in the apropriate init function before any console commands are executed:
Cvar_RegisterVariable (&host_framerate);
C code usually just references a cvar in place:
if ( r_draworder.value )
It could optionally ask for the value to be looked up for a string name:
if (Cvar_VariableValue ("r_draworder"))
Interpreted prog code can access cvars with the cvar(name) or
cvar_set (name, value) internal functions:
teamplay = cvar("teamplay");
cvar_set ("registered", "1");
The user can access cvars from the console in two ways:
r_draworder prints the current value
r_draworder 0 sets the current value to 0
Cvars are restricted from having the same names as commands to keep this
interface from being ambiguous.

Glquake v0.99, Quake v1.09 release notes
3dfx owners -- read the 3dfx.txt file.
On a standard OpenGL system, all you should need to do to run glquake is put
glquake.exe in your quake directory, and run it from there. DO NOT install
the opengl32.dll unless you have a 3dfx! Glquake should change the screen
resolution to 640*480*32k colors and run full screen by default.
If you are running win-95, your desktop must be set to 32k or 64k colors
before running glquake. NT can switch automatically.
Theoretically, glquake will run on any compliant OpenGL that supports the
texture objects extensions, but unless it is very powerfull hardware that
accelerates everything needed, the game play will not be acceptable. If it
has to go through any software emulation paths, the performance will likely
by well under one frame per second.
3dfx has provided an opengl32.dll that implements everything glquake needs,
but it is not a full opengl implementation. Other opengl applications are
very unlikely to work with it, so consider it basically a "glquake driver".
See the encluded 3dfx.txt for specific instalation notes. 3dfx can only run
full screen, but you must still have your desktop set to a 16 bit color mode
for glquake to start.
resolution options
------------------
We had dynamic resolution changing in glquake for a while, but every single
opengl driver I tried it on messed up in one way or another, so it is now
limited to startup time only.
glquake -window
This will start glquake in a window on your desktop instead of switching the
screen to lower resolution and covering everything.
glquake -width 800 -height 600
Tries to run glquake at the specified resolution. Combined with -window, it
creates a desktop window that size, otherwise it tries to set a full screen
resolution.
You can also specify the resolution of the console independant of the screen
resolution.
glquake -conwidth 320
This will specify a console resolution of 320 by 240 (the height is
automatically determined by the default 4:3 aspect ratio, you can also
specify the height directly with -conheight).
In higher resolution modes such as 800x600 and 1024x768, glquake will default
to a 640x480 console, since the font becomes small enough at higher
resolutions to become unreadable. If do you wish to have a higher resolution
console and status bar, specify it as well, such as:
glquake -width 800 -height 600 -conwidth 800
texture options
---------------
The amount of textures used in the game can have a large impact on performance.
There are several options that let you trade off visual quality for better
performance.
There is no way to flush already loaded textures, so it is best to change
these options on the command line, or they will only take effect on some of
the textures when you change levels.
OpenGL only allows textures to repeat on power of two boundaries (32, 64,
128, etc), but software quake had a number of textures that repeated at 24
or 96 pixel boundaries. These need to be either stretched out to the next
higher size, or shrunk down to the next lower. By default, they are filtered
down to the smaller size, but you can cause it to use the larger size if you
really want by using:
glquake +gl_round_down 0
This will generally run well on a normal 4 MB 3dfx card, but for other cards
that have either worse texture management or slower texture swapping speeds,
there are some additional settings that can drastically lower the amount of
textures to be managed.
glquake +gl_picmip 1
This causes all textures to have one half the dimensions they otherwise would.
This makes them blurry, but very small. You can set this to 2 to make the
textures one quarter the resolution on each axis for REALLY blurry textures.
glquake +gl_playermip 1
This is similar to picmip, but is only used for other players in deathmatch.
Each player in a deathmatch requires an individual skin texture, so this can
be a serious problem for texture management. It wouldn't be unreasonable to
set this to 2 or even 3 if you are playing competatively (and don't care if
the other guys have smudged skins). If you change this during the game, it
will take effect as soon as a player changes their skin colors.
GLQuake also supports the following extensions for faster texture operation:
GL_SGIS_multitexture
Multitextures support allows certain hardware to render the world in one
pass instead of two. GLQuake uses two passes, one for the world textures
and the second for the lightmaps that are blended on the textures. On some
hardware, with a GL_SIGS_multitexture supported OpenGL implementation, this
can be done in one pass. On hardware that supports this, you will get a
60% to 100% increase in frame rate. Currently, only 3DFX dual TMU cards
(such as the Obsidian 2220) support this extension, but other hardware will
soon follow.
This extension will be autodetected and used. If for some reason it is not
working correctly, specify the command line option "-nomtex" to disable it.
GL_EXT_shared_texture_palette
GLQuake uses 16bit textures by default but on OpenGL implementations
that support the GL_EXT_shared_texture_palette extension, GLQuake will use
8bit textures instead. This results in using half the needed texture memory
of 16bit texture and can improve performance. This is very little difference
in visual quality due to the fact that the textures are 8bit sources to
begin with.
run time options
----------------
At the console, you can set these values to effect drawing.
gl_texturemode GL_NEAREST
Sets texture mapping to point sampled, which may be faster on some GL systems
(not on 3dfx).
gl_texturemode GL_LINEAR_MIPMAP
This is the default texture mode.
gl_texturemode GL_LINEAR_MIPMAP_LINEAR
This is the highest quality texture mapping (trilinear), but only very high
end hardware (intergraph intense 3D / realizm) supports it. Not that big of
a deal, actually.
gl_finish 0
This causes the game to not issue a glFinish() call each frame, which may make
some hardware run faster. If this is cleared, the 3dfx will back up a number
of frames and not be very playable.
gl_flashblend 0
By default, glquake just draws a shaded ball around objects that are emiting
light. Clearing this variable will cause it to properly relight the world
like normal quake, but it can be a significant speed hit on some systems.
gl_ztrick 0
Glquake uses a buffering method that avoids clearing the Z buffer, but some
hardware platforms don't like it. If the status bar and console are flashing
every other frame, clear this variable.
gl_keeptjunctions 0
If you clear this, glquake will remove colinear vertexes when it reloads the
level. This can give a few percent speedup, but it can leave a couple stray
blinking pixels on the screen.
novelty features
----------------
These are some rendering tricks that were easy to do in glquake. They aren't
very robust, but they are pretty cool to look at.
r_shadows 1
This causes every object to cast a shadow.
r_wateralpha 0.7
This sets the opacity of water textures, so you can see through it in properly
processed maps. 0.3 is very faint, almost like fog. 1 is completely solid
(the default). Unfortunately, the standard quake maps don't contain any
visibility information for seeing past water surfaces, so you can't just play
quake with this turned on. If you just want to see what it looks like, you
can set "r_novis 1", but that will make things go very slow. When I get a
chance, I will probably release some maps that have been processed properly
for this.
r_mirroralpha 0.3
This changes one particular texture (the stained glass texture in the EASY
start hall) into a mirror. The value is the opacity of the mirror surface.
