Linux Glquake v0.98, Quake v1.09 release notes
|
|
|
|
Requirements
|
|
------------
|
|
|
|
For 3DFX based hardware, you must download and install Linux GLIDE from
|
|
http://glide.xxedgexx.com/3DfxRPMS.html and install as per the
|
|
instructions.
|
|
|
|
Running GLQuake
|
|
---------------
|
|
|
|
There are three different ways to execute GLQuake:
|
|
|
|
1. The binary "glquake" requires Mesa 3-D 2.5 or later installed and compiled
|
|
with 3DFX support (fxMesa..() function interface). It also requires
|
|
svgalib 1.3.0 or later for keyboard/mouse input. This binary is a console
|
|
application. Mesa 3-D requires GLIDE to be installed.
|
|
|
|
2. The shell script "glquake.3dfxgl" runs the "glquake" binary after
|
|
preloading the lib3dfxgl.so library. This is a port of 3DFX's Win32
|
|
OpenGL MCD (Mini Client Driver) to Linux. It is faster than Mesa 3-D
|
|
since it was written specifically with supporting GLQuake in mind.
|
|
lib3dfxgl.so requires that GLIDE be installed.
|
|
|
|
3. The binary "glquake.glx" is linked against standard OpenGL libraries.
|
|
It should run on many different hardward OpenGL implementations under
|
|
Linux and X11. This binary is an X11 application and must be run under
|
|
X11. It will work with Mesa 3-D as a standard glX based OpenGL
|
|
applications. If the Mesa 3-D library is compiled with 3DFX support,
|
|
you can have Mesa 3-D support 3DFX hardware under X11 by setting the
|
|
enviroment variable "MESA_GLX_FX" to "fullscreen" for fullscreen mode
|
|
and "window" for windowed mode.
|
|
|
|
You must also have SVGALib 1.3.0 or later installed. GLQuake uses SVGALib
|
|
for mouse and keyboard handling.
|
|
|
|
If you have gpm and/or selection running, you will have to terminate them
|
|
before running GLQuake since they will not give up the mouse when GLQuake
|
|
attempts to run. You can kill gpm by typing 'killall gpm' as root.
|
|
|
|
You must run GLQuake as root or setuid root since it needs to access things
|
|
such as sound, keyboard, mouse and the 3DFX video. Future versions may not
|
|
require root permissions.
|
|
|
|
resolution options
|
|
------------------
|
|
glquake -width 512 -height 384
|
|
Tries to run glquake at the specified resolution.
|
|
Only highend VooDoo cards support such high resolutions (most
|
|
cards on the market right now do not). Another popular and supported mode
|
|
is 512x384 (-width 512 -height 384) which can offer a faster speed than
|
|
the default 640x480.
|
|
|
|
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.
|
|
|
|
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.
|
