Bill Currie
745bdfafdf Eliminate QFS_LoadHunkFile(). 
It is unused, and part of the group of functions I wish to remove from QF.
 2010-08-25 13:31:23 +09:00
Bill Currie
cbee789fe1 Change ProgPath to ModelPath and dir.progs to dir.models. 
The default is still $path/progs, as that is what is expected by the
game-code.

cf40f5073d Nuke QFS_WriteBuffers. 
This function is too dangerous for my liking, and it's now unnecessary
since qfs has been locked down.
 2010-08-25 13:31:13 +09:00
Bill Currie
031055a91f Move the qfs_* cvars out of quakefs.h 
The qfs cvars are all private.
 2010-08-25 13:31:13 +09:00
Bill Currie
0cc4bc8c69 Move searchpath out of quakefs.h. 
It's not needed, nor should it be used, anywhere else.
 2010-08-25 13:31:13 +09:00
Bill Currie
478394ef81 Nuke MAX_GAMEDIR_CALLBACKS 
The number of gamedir callbacks is now unlimited.
 2010-08-25 13:31:08 +09:00

baede61f4f New function: dstring_strdup 
I got tired of always doing dstring_newstr/dstring_copy, so I thought it
was time to wrap it. dstring_strdup is the dstring equivalent of strdup.

fd24170b32 get the behavior or PL_NewData correct 
It taking ownership of the data was the correct behavior, so go back to that.
 2010-08-20 13:21:22 +09:00

a744caa421 The public api of qfplist is now fully documented. 
Evertyhing that can or should be private now is, and all public functions

997102fea8 audit the usage of "only" 
There are still a few iffy places (notably around certain prepositions), but
the relevant sentences are now much easier to read.
 2010-01-13 06:42:26 +00:00
Bill Currie
0a203c0ab5 qccx (etc) "integer" autodetection. 
Check for usage of denormal floats and if found, either bail with a
descriptive error message or give a mild warning that things will probably
break. This avoids the possibility of things like RuneQuake getting "lucky"
and doing real harm, and certainly avoids the segfaults.

fe4a4a9e55 "hardware" (haha) watch points (one!) in progs. only catches changes done by progs, and the expression parser is as flaky as anything, but it's better than nothing :) 2007-05-08 02:04:47 +00:00

7af2378e03 turn on graph generation in the doxygen output. very slow, but the diagrams are worth it. Also make the data member of sfx_t a union rather than void so doxygen can see the relationships (and gets rid of a bunch of casts that I never liked anyway). 2007-05-07 05:20:24 +00:00

7925e16d73 audit the usage of view_draw. It is really meant for draw callbacks, not direct usage by the application. 2007-04-09 00:22:17 +00:00
Bill Currie
2894182ec5 The status bar in the quakeworld server curses console finally does something. Currently only cpu usage, but as a proof-of-concept, it more than does its job. 2007-04-09 00:10:10 +00:00

99c0954b47 the big dso visibility patch :). Sure, we have to have unique names for static builds, but with controlled visibitly we should get faster program loads (although this isn't C++, so it's not as bad) and complex plugins are cleaner. 2007-03-10 12:00:59 +00:00

29502c8f5a Lots of optimizations, particularly for GL state changes, and tweak lighting a 
bit more.

Also a cleanup from Grievre: Use VectorIsZero in two places in gl_mod_alias.c.

9cd16b8dfd Grievre's lighting patch, plus some of my own changes. 
My changes:
Emit normals if truform is enabled.
Attempt to avoid 0,0,0 normals (makes lighting & tesselation unhappy).
Fix some (ancient) apparent bugs in GetAliasFrameVerts16().
Clamp minlight, instead of adding it.
Apply colormod as glColor, rather than adding it to emission, to prevent QSG2
 issues with fullbrights.
Rearrange init code, and don't go quite as wild with responsiveness to lights.

Material & lightmode settings will need tweaking & testing to work well on all
 cards. Feedback needed there.

b7df0b5278 Remove gl_doublebright, remove fractional overbrights, clean up init a bit, 
uglify init a bit. Stuff for taniwha to look at. Nothing to see here, move
along.

37024a4419 final (?) cleanup of center printing. turns out there's no reason to keep 
it in the renderer and every reason to pull it out (ok, some might
disagree:)

44c89c1904 Optimize fullbright testing for brushes, assorted other cleanups, test for 
functions built into current GL drivers, as well as the old extensions, and
add incorrectly rendering BGRA support.
Whee!

872498a1f0 Reorder a lot of code, removing tons of ifs. multitexture paths are a bit more 
sane now. Also optimize QSG2 color handling, and fix some QSG2 bugs. Not that
anyone cares, nobody uses it anyways.
Should be faster, but isn't here. *grmbl*

5157f668ad Fix a bunch of state leaks that made multitextured fullbrights smear the world. 
Now just have one (known) issue with bmodels with fullbright textures not
rendering their base texture. Floating fullbrights are nifty!

Also a number of optimizations, which need wider performance testing.
