59c5bf2f9e Code up an initial version of the iqm vertex shader. 
Probably more bugs than an old kitchen cupboard :P

866c56c236 Do not try to lerp entities when their model changes. 
This avoids sending invalid pose data to the renderer. The symptom was a
vertex array offset higher than the vertex array size. Discovered by calim
of nouveau while he was debugging a driver problem found by QF. Many
thanks.

bc1b483525 Nuke the rcsid stuff. 
It's pretty useless in git.

1fd84477a2 Rename char to dchar in the text vertex shader. 
Thanks to Spirit :)

Turns out certain drivers (nvidia?) reserve "char" even though opengl does
not. This should fix his missing console text.

3b07928373 Fix an inconsistent numeric constant. 
While checking the shaders to see if there might be anything obvious to
work around the current nouveau shader issues, I found a 1 that should have
been a 1.0. I'm surprised it ever compiled.

e784754a11 Disable the gl_triplebuffer check in glsl. 
It doesn't seem to have any useful effect in QF (even before the plugin
project) other than setting the number of frames to update. I'm not sure if
it's a useless variable or one where the user is supposed to match it to
the system configuration. Anyway, with this, the glsl plugin now works.
 2012-04-12 14:40:02 +09:00
Bill Currie
8401704c4e Connect up palette setting for gl and glsl. 
The GL plugin now seems to work. GLSL still segs :(
 2012-04-12 13:57:05 +09:00
Bill Currie
525dbcc13e Ensure code paths stay within the one renderer. 
The gl renderer calling sw functions is bad news. Still all black, but I
think that's because palette setting is disabled.
 2012-04-11 22:45:23 +09:00
Bill Currie
898bfa5e5f Split up the vid plugin init sequence. 
This gets gl so it no longer segs. However, the screen remains black
(expect for cshifts).
 2012-04-11 16:44:38 +09:00
Bill Currie
d62772e9cc Separate render module loading from initialization. 
This allows the vid module to load the render module and access render
specific functions before the renderer initializes, which happens to need
an initialized vid module...
 2012-04-11 14:58:56 +09:00
Bill Currie
6ea4e6617a Connect up viddef properly. 
Or mostly so, anyway. sw32 is actually putting stuff on the screen.
 2012-04-11 14:58:55 +09:00
Bill Currie
4d9c3408a1 Start putting the pieces back together. 
The renderer now gets initialized and things sort of work (qw-client will
idle, though nothing is displayed). However, as the viddef stuff is broken,
it segs on trying to run the overkill demo.
 2012-04-11 14:58:55 +09:00
Bill Currie
e08d5ccb41 Move the gl util functions into viddef_t. 
Static plugins almost link now, just two more symbols to sort out.
 2012-04-11 14:58:55 +09:00
Bill Currie
1dd1aec48f Make libgl_handle static. 
This will make life interesting for getting the final stages working, but
it helps for now.
 2012-04-11 14:58:54 +09:00
Bill Currie
772af29cb3 Move the gl cvars into gl. 
That gets rid of the gl_overbrite_f clash. They were put in r_cvar for
saving to the config file, but that was before seta existed.
 2012-04-11 14:58:54 +09:00
Bill Currie
65bd29353c Make a start on putting the pieces together. 
Still many undefined and multiply defined symbols, but there seems to be a
light in this darkness. I just hope it's not an oncoming train :)
 2012-04-11 14:58:54 +09:00
Bill Currie
d445b4ef88 Rename the glsl qfgl functions to qfegl. 
Keep them separate from the gl renderer :)
 2012-04-11 14:58:54 +09:00
Bill Currie
36504547a8 Rename the public symbols for gl, glsl and sw32. 
Evil hack, but it does the job.
 2012-04-11 14:58:54 +09:00
Bill Currie
8de5c9ae3f Do a final cleanup before doing the big rename. 2012-04-11 14:58:54 +09:00
Bill Currie
db4a463727 Remove VISIBLE from the files that will go into the plugins. 2012-04-11 14:58:54 +09:00
Bill Currie
eb536dc995 Remove D_BeginDirectRect and D_EndDirectRect from gl/glsl. 
They were never really needed anyway (they're for the sw renderer).
 2012-04-11 14:58:54 +09:00
Bill Currie
e991c1fed3 Make a bit of progress cleaning up vid for plugins. 2012-04-11 14:58:54 +09:00
Bill Currie
96b80433d8 Make some progress in getting static plugins to link. 
Still many redefined symbols (and I expect more to come), and many
undefined symbols too.
 2012-04-11 14:58:54 +09:00
Bill Currie
a4c280f2b2 Take the first step towards render plugins. 
No clients link. Even if they did, nothing would work.
 2012-04-11 14:58:53 +09:00
Bill Currie
ef37ed39a9 Clean up global symbols for the glsl renderer. 
Where possible, symbols have been made static, prefixed with glsl_/GLSL_ or
moved into the code shared by all renderers. This will make doing plugins
easier but done now for link testing. The moving was done via the gl
commit.
 2012-02-18 11:48:52 +09:00
Bill Currie
447ff2f2f5 Clean up global symbols for the gl renderer. 
Where possible, symbols have been made static, prefixed with gl_/GL_ or
moved into the code shared by all renderers. This will make doing plugins
easier but done now for link testing.

78789a6833 Add support for blender's environment maps. 
QF will now load a single image with (${skyname}_map.*) using blender's
layout. That is, 3x2 with the top row being back, right, front and the
bottom row being bottom, top, left.
 2012-02-16 20:47:38 +09:00
Bill Currie
bfdb2b20d5 Clearify skybox layout. 
Turns out quake skynames have left and right backwards.
 2012-02-16 20:42:49 +09:00
Bill Currie
4707706f5d Use QF_NEED for the renderer and model libraries. 
This breaks RPM building, but I can fix that later.
 2012-02-10 13:29:45 +09:00

a694eed968 Add Draw_Picf to allow smooth placement on low-res consoles. 2012-02-06 19:32:30 +09:00

Sander van Dijk
82adc67a67 glsl_bsp.c: __builtin_expect() to avoid compiler warnings. 2012-02-02 16:55:25 +09:00
Bill Currie
f800e79a38 Make the init process more dependency based. 
Most subsystems that depend on other subsystems now call the init functions
themselves. This makes for much cleaner client initialization (more work
needs to be done for the server).
 2012-02-01 21:52:47 +09:00
Bill Currie
bc2aca53c3 Add functions to create/destroy qpics. 
The creation uses raw 8-bit data (and the system palette). Destroying a
qpic loaded via other means will probably produce nasal demons.
 2012-02-01 17:46:15 +09:00
Bill Currie
7e406c20e5 Allow uncaching of qpics. 
qpics loaded via Draw_CachePic can now be uncached via Draw_UncachePic.

706f09b247 Put the transparent surfaces on the water chain. 
I'd actually done this the first time, but then got confused and forgot the
waterchain works with multiple textures. This is actually the right place
as all transparent surfaces need to be sorted irrespective to their
textures. Really, waterchain needs to be renamed.
 2012-01-31 18:08:06 +09:00
Bill Currie
b286a35281 Sort transparent surfaces back to front. 
This allows overlapping transparent surfaces to look like they are
overlapping each other rather than only the nearest one showing.

c3d2365bd8 Fix a missed default_color init. 
Wish I'd caught this earlier :/
 2012-01-30 21:02:13 +09:00
Bill Currie
c01255a387 Fix a case&paste error. 
Doesn't fix the color problem for water surfaces on my eeepc, though :(
 2012-01-30 20:31:58 +09:00
Bill Currie
8f0ce733ff Sanitize color handling a little. 2012-01-30 20:31:37 +09:00
Bill Currie
4b948de225 Ensure the lightmap gets rebuilt when the dlights disappear. 
I didn't realize what that line was for when I copied the code from GL :/
 2012-01-30 18:41:27 +09:00
Bill Currie
497718cc40 Plug the memory/texture/vbo leaks. 
QF still leaks about 3MB/run on demo1, but even 100 runs didn't show any
render issues.
 2012-01-29 22:32:35 +09:00
Bill Currie
b03e937b67 Implement brush entity alpha. 
http://www.celephais.net/board/view_thread.php?id=60157& has a good map for
testing (you see an example straight away if you look up). (+set max_edicts
2048)
 2012-01-29 16:56:50 +09:00
Bill Currie
8f869c001b Fix the missing world on map reload. 
If the map got reloaded but the current leaf didn't change the world (and
most entities) didn't get drawn. Forcing a vis update by first setting
r_viewleaf to null and marking surfaces does the trick :)
 2012-01-29 16:09:35 +09:00
Bill Currie
462a9047c6 Fix the missing fog on particles and sprites. 
Bah, definitely need a metter method of parameter interrogation.
 2012-01-29 10:35:23 +09:00
Bill Currie
731236ee07 Implement global fog. 
Sprites and particles don't seem to be getting fogged correctly, but bsp
and alias models are working.

7e078c7f9c Revamp cshifts and implement in glsl. 
The renderer should now be free of any direct access to client code. Even
3d rendering is now done via a function pointer.

The cshift code is done as a 2d screen function.

2595251162 Do not update every visible lightmap every frame. 
This takes nq from ~25fps to 65-72 fps on Unforgiven's start map.
 2012-01-27 21:48:25 +09:00

08990ebb5a Make top/bottom color work for GLSL. 
Works quite nicely (love those colormaps).
 2012-01-23 19:24:12 +09:00
Bill Currie
7bfddd7ffe Gut most of the old skin code. 
Custom skins are smashed on most targets. Player colors don't work, etc.
However, this will let me do a much cleaner implementation.
 2012-01-23 16:16:30 +09:00
Bill Currie
61c127abc0 Make a start on skin support. 
I had this lying around for a while since it was more important to get
other things working first.
 2012-01-22 15:49:01 +09:00

76cb60461d Tweak the size of point particles. 
This looks fairly reasonable, but should probably be tweaked further to
base the point size on resolution.
 2012-01-21 22:05:24 +09:00
Bill Currie
5080a6f37e Enable the point size shader variable. 
This is a rather "evil" hack because GLES doesn't seem to need
GL_VERTEX_PROGRAM_POINT_SIZE, but GL does, and all my work is currently
done in GL rather than GLES. Point particles now work, but the sizes are
all wrong.
 2012-01-21 21:54:36 +09:00
Bill Currie
68d956583d Draw ALL of the particles, not just 2/3 of them. 
Using quads requires 4 elements, but triangles require 6. I'd gotten the
element array setup right, but I'd forgotten to tweak vacount when drawing
the particles.
 2012-01-21 20:16:18 +09:00
Bill Currie
8345f07db2 Implement QF style particles. 
Actually looks pretty good against the sw style world.
 2012-01-21 19:51:18 +09:00
Bill Currie
358bbc4439 Disable the sky spin effect. 
It's cool, but not appropriate as a default. All that's needed is a way to
set (and optionally update) sky_velocity (map vars? qc?).
 2012-01-21 17:18:29 +09:00
Bill Currie
62c5070d8b Use the correct type for particle colors. 
Sending byte data as floats doesn't work too well :P Fixes the colors of
the particles, but not the size :(.
 2012-01-21 16:17:54 +09:00
Bill Currie
2cb2f230fd Print out the point size range. 
I'm not sure if there's a bug in mesa, or if I'm doing something wrong, but
GL_POINTS doesn't seem to be working properly. I get the points, but
writing to gl_PointSize doesn't make a difference despite the size range
being 1-255.
 2012-01-21 15:48:21 +09:00
Bill Currie
5e1a80e016 Implement particles as points. 
Unfortunately, the maximum point size on Intel hardwar seems to be 1, so I
can't tell if the colors are right.

This is largely just a hacked version of GL's particle code.
 2012-01-19 10:39:03 +09:00

42bb10a3d7 Clear out the lightmap scrap at each level change. 
This allows the demo loop to run more than 4 times (12 demos). Once the
rest of the resource management is done, demos should run indefinitely.
 2012-01-17 19:31:50 +09:00
Bill Currie
fc43e5a307 Allow clearing of a scrap. 
This "frees" all rectangles and subpics allocated from a scrap. subpics
are owned by the scrap from which they are allocated.
 2012-01-17 19:31:50 +09:00
Bill Currie
3669e3aa2e Make alias model caching optional. 
For now, only the glsl loader disables caching, but it stores the frame
vertices in GL memory, so its hunk usage is relatively lower (and will be
lower still when I get skins sorted out).
 2012-01-17 19:31:50 +09:00
Bill Currie
c884ef5f80 Convert the colormap to a 2D palette. 
This skips one level of indirection in the alias model and brush shaders.
Hopefully, this will improve performance on my eeepc.
 2012-01-14 21:42:42 +09:00
Bill Currie
928dd92276 Use 0.0 instead of 0.5 for t for palette lookups. 
I realized it's pretty silly using colormap + palette when I can just
combine the two into one and have a 2D palette. This is in preparation for
that.

de022ae72d Rewrite GL_LoadQuakeMipTex to generate mips itself. 
Relying on GL to generate mips for 8 bit textures doesn't produce nice
results. These aren't the greatest, either, but they're better.

Quake and GL are rotated relative to each other, so care must be taken

f1eea0176c Fix the too near far-clip plane.

e38d72f50b Get brush entity rendering working. 
Unfortunately, the intel driver on my eeepc doesn't like the mipmas for
plat_top2 or +2floorsw. If I either don't load their mipmaps, or skip
drawing them, things seem to work nicely.
 2012-01-10 13:06:02 +09:00
Bill Currie
3326aceed8 Rewrite the texture chain index list building. 
It turns out my complicated plan was just that: complicated. Although there
