3efb0c538f Separate file search from loading. 
QFS_LoadFile (and its wrappers) now  take a file handle rather than a
path. This will make vpath usage a little cleaner to implement.

4d59282641 Find the remaining vertex attribute order issues. 
I hope. I do need to figure out why I made sprite blend an attribute
rather than a uniform.

a5db0b1a65 Remove the now unnecessary GLSL_CompileShaderS(). 
Now that the transition to using shader effects is comlete, there's no
need for the wrapper.

a419fb2c92 Ensure the vertex coord attribute is attribute 0. 
It seems mesa still has the bug where non-array attributes don't work
when set as attribute 0, and that the allocation order changed sometime
since I last tested with mesa. This fixes the black world and flickering
alias models on my eeepc.

f43592589d Use the new shader system in the bsp renderer. 
It mostly works. Skybox is untested, and water surfaces are broken.

b269338947 Start using the new shader system. 
So far, alias model rendering is the only victim, but things are working,
even if only color map lookup and fog blending are broken out at this
stage.

I expect the effect naming scheme will go through some changes until I'm
happy with it.

96c40cb9a1 Add basic support for shader "effects". 
Again, based on The OpenGL Shader Wrangler. The wrangling part is not used
yet, but the shader compiler has been modified to take the built up shader.
Just to keep things compiling, a wrapper has been temporarily created.

88692f92d9 Fix the calls for Draw_Init in the gl renderers. 
While namehack.h took care of the symbol mangling, I do prefer the calls to
be correct as it reduces confusion.

6d7f747577 Add timerefresh to the glsl renderer. 
Also, tweak the formatting of the output for the other renderers (%g
instead of %f) and make gl's timerefresh output unconditional.

bc12567572 Clean out a leftover from the 128 dlight change. 
I'd missed a set of bit->lightnum conversions that resulting in lightnum
becoming much greater than 128 and thus trashing memory when the surface
was marked.

f1aefc969d Fix some 64-bit mingw compile issues. 
Just one more issue to fix (alloca), but with a hack, QF compiles (no clue
yet if it works: wine doesn't seem to be an option at this stage)

cb45d248c4 Use the Mersenne Twister for particles. 
The seed is currently 0xdeadbeef, but I intend on fixing that soon. Now the
particle velocities and origins use fully independent bits (though a big
chunk is wasted right now).
 2013-01-21 20:06:54 +09:00
Bill Currie
3de67589a3 Fix random particle origin/velocity z component. 
This is a quick fix until I get a random number generator into QF.

Mingw's RAND_MAX is only 0x7fff and so the (((rnd >> 10) & 63) - 31.5) / 63.0
used for the z component of origin and velocity would never go positive.
For now, change the 10 to 9 (reusing another bit from Y). I plan on
implementing a full 32-bit PRNG in QF so we always have a reliable
generator.

3cb0f3e183 Remove viddef in favor of vid in the renderers. 
This fixes the status bar refresh issues in sw. The problem was that with
two viddef's hanging around, things got a little confused and recalc_refdef
wasn't getting into the renderer.

0c81364da8 Fix scr_copyeverything in gl and glsl. 
Now the gl renderers unconditionally set it to 1. This is required because
the screen is cleared every frame.

SCR_UpdateScreen is called.

5bbb76194f Use stdlib.h instead of alloca.h. 
While the manpage does say alloca.h, that's not very portable, it seems.
stdlib.h seems to be better (at least for mingw, anyway)

9758302023 Fix sw and sw32's R_RecursiveWorldNode node stack.

43702580f5 Clear the texture element chain after drawing. 
It was properly cleared after drawing water chains and sky chains, but I
had missed normal surfaces. It took the use of the same texture for both
normal surfaces and water surfaces to trigger the bug. Thanks go to Simon
'Sock' O'Callaghan and his In The Shadows mod.

6eb6b6c0ba Change pointer_t to unsigned and clean up the mess. 
It doesn't make sense to have negative pointers. The size of the commit is
from enabling gcc's -Wtype-limits warning and cleaning up that mess too.

Bill Currie
f71affdfba Use exact texture coords for 2d pics in glsl. 
Moving the texture coordinates in 1/4 pixel made a mess of the 2d pics
(very noticable on the round crosshair).
 2012-12-12 21:34:37 +09:00
Bill Currie
a372efee5c Add a new crosshair. 
Now all 4 slots of the crosshair table are used :)

Also, fix the offset for pic based crosshairs in glsl, and use just one
func for them.

a12eb940f1 Remove the hard-coded bsp maximum depths. 
The depth limits in the gl and glsl renderers and in the trace code really
bothered me, but then the fix hit me: at load-time, recurse the trees
normally and record the depth in the appropriate place. The node stacks can
then be allocated as necessary (I chose to add a paranoia buffer of 2, but
I expect the maximum depth will rarely be used).

6e04fd5ff6 signed int viddef_t members 
The attached patch (against quakeforge git) changes the [con]width,
[con]height, and most importantly the rowbytes members of viddef_t
from unsigned to signed int, like in q2.  This allows for a properly
negative vid.rowbytes which may be needed in, e.g. a DIB sections
windows driver if needed.  Along with it, I changed a few places
where unsigned int is used along with comparisons against the relevant
vid.* members.
One thing I am not 100% sure is the signedness requirements of
d_zrowbytes and d_zwidth: q2 has them as unsigned but I am not sure
whether that is because they are needed as unsigned or it was just an
oversight of the id developers. They do look like they should be OK
as signed int to me, though: comments?

==
Note from Bill Currie: I had to do some extra changes as many
signed/unsigned comparisons were somehow missed.

709da6e7d7 Rotate the skybox -90 degrees on the z axis (gl) 
Now gl and glsl match again, and quake's skies are now "correct" (assuming
fitzquake is the standard).
 2012-09-13 08:36:28 +09:00
Bill Currie
14f089d08e Correct the orientation of the skybox (for glsl). 
It turns out the expected orientation of the sky cube is exactly that of
Blender's default cube looked at from the front view (num-1) and the front
face being the nearest face. This put's Marcher's sun nicely in the view
when exiting the cave.
 2012-09-12 19:06:07 +09:00
Bill Currie
536ee48a97 Some minor skybox improvements suggested by mh. 
Rearrange the sky_suffix and sky_coords arrays and remove the sky_target
array such that the faces can be loaded using
GL_TEXTURE_CUBE_MAP_POSITIVE_X + i (apparently certain drivers break if
the faces aren't loaded in the correct order).

Also, the nomalization of the direction vector in the fragment isn't
necessary.

a37c5465e1 First step for BSP2 support. DOES NOT WORK! 
All of the nastiness is hidden in bspfile.c (including the old bsp29
specific data types). However, the conversions between bsp29 and bsp2 are
implemented but not yet hooked up properly. This commit just gets the data
structures in place and the obvious changes necessary to the rest of the
engine to get it to compile, plus a few obvious "make it work" changes.

5a5b31bae4 Correct the direction of pt_fire particles. 
sub_grav() was accelerating the particle in the wrong direction. Down being

372defc1be Support up to 128 dlights. 
More or less as per MH's tut, but really just finishing something that

7d8b0f96d6 Correct the fog distance calculations. 
It turns out the pixel's z coord is correctly obtailed by
gl_FragCoord.z/gl_FragCoord.w.
 2012-07-17 19:10:10 +09:00

c4309e7abc Correct the fog blend calculation for transparency.

a7327acb80 Set up shadevector for gl alias models. 
The setup had been lost at some stage, thus shadows were always directly
under the entity. Unlike the original quake shadow code, the vector is
correctly transformed into the entity's space.

fbc0ad59df Implement gl shadows for pure triangle alias models. 
I finally found the cause of Despair's gl shadows non-rendering+segfault...

6fe32103ea Do a bit of bound() usage auditing.

a822a683cd Fix the inverted lighting for sw32. 
LordHavoc had made lighting positive for sw32, but I had done something in
the plugin code that broke that (probably something to do with the
colormap loading). Going back to id's original code fixes the issue.

12319cfcdf Revert "Slightly reducde the number of calls to glUniformMatrix4fv." 
This reverts commit e170f4ee75.

It turns out I messed up something in the patch. I noticed the problem
while playing digs04.bsp: many sub-model surfaces, particularly those with
animated textures, were not being transformed correctly. As this patch did
not make a large performance difference, it's probably better to just
revert it. I might revisit it later.

Bill Currie
5014825b39 Fix the backtile for glsl. 
Since the backtile is loaded into a scrap and used as a subtexture, we
can't use GL's texture wrapping, thus do the wrapping ourselves. There are
some minor issues with the wrong part of the scrap being drawn: need to
investigate where the bug is (vrect, make_quad, etc).

ee1cb24e3d Move the call to R_SetFrustum to gl_R_SetupFrame.

 2012-07-03 16:08:12 +09:00
Bill Currie
a8e0bcabf9 Call R_SetFrustum in all renderers. 
It turns out glsl, sw and sw32 weren't getting any benefit from R_CullBox
because the frustum wasn't setup :P. Get another 8% out of bigass1
(174->184fps). bigass1 now runs 2x as fast as it did before I started this
optimisation run :)

Bill Currie
b25de4d995 Rewrite the 2d code to use a scrap. 
This severely reduces the calles to BindTexture, and more importantly,
glUseProgram, EnableVertexAttribArray etc. The biggest changes are:

 o  icons and text are all in the one giant texture
 o  icons and text are mixed in the one queue

This gave ~9% speedup for bigass1 (159->174fps).

c0517b1d97 Factor out the blend palette creation. 
gl, sw and sw32 use blend palettes, so share the code. This also abandons

c3801d46e5 Render iqm models in GL. 
There are still many issues to sort out, but the basics are working.

Problems:
	rendered fullbright (no lighting done)
	normals are ignored
	extra textures (glow etc) not used/loaded

4 models on the screen don't seem to be a problem.

It was there only because mrfixit is rather small (8qu?) and it made
finding him easier :). Anyway, any scaling should be done in the engine.

31772afd13 Add in some ambient light for iqm models. 
Though the bsp loader doesn't yet support colored lighting, the ambient
light will be colored when it does. With this, I guess iqm model support is
done for glsl until I figure out how I want to do dual quaternion support.

866c56c236 Do not try to lerp entities when their model changes. 
This avoids sending invalid pose data to the renderer. The symptom was a

thanks.

e167300a84 Fix a segfault in the sw32 renderer on entering e1m7 
While this particular tigger of the real bug was caused by 659d95221e
(hopefully fix both the "get stuck waiting for 3d" bug and the null
worldmode bug.), the real bug was lurking in the code since the dawn of
time (from sw32's perspective). This fix is as per LordHavoc's suggestion
(heh, despite the years, he knows his code), but I spent the time hunting
down the trigger to understand just what was going on.

It turns out that (0,0,0) is too close to a wall (probably on, but the
slight default offset is too close) and the above commit changed the first
rendered frame to be before the player origin was set rather than after.
This fix feels correct to me because noclipping around with the sw32
renderer would probably hit the same bug with a bit of bad luck. Thus
ensure the index resulting from zi never exceeds 65535.

e784754a11 Disable the gl_triplebuffer check in glsl. 
It doesn't seem to have any useful effect in QF (even before the plugin

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.

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

all wrong.

1437cbec91 Make the face culling a little more sensible. 
GL Quake was weird, culling front faces. Partly understandable, since
Quake's front order is clockwise and GL's default order is
counter-clockwise. However, since the order can be specified, that should
be done instead. Thus, specify the winding order as clockwise (for quake's
data), set culling for back-face removal, and then mess with the winding
direction in the mirror and fish-eye code.

with that). s and t need to be at least short, and since the normal index
is embedded in the st vector, it needs to be the same type. With this, my
test tetrahedrons seem to be working.

Bill Currie
55e53b796d Make a start on getting sprites rendering. 
The plan is to do interpolated sprites based on a discussion I had with
LordHavoc about them: blending between the two sprite frames. He didn't

necessary too.

Bill Currie
e69a583f1b Work around a bug in mesa. 
Since I'm not specifying the api when creating my context, mesa is giving
me GL2. This is fair enough, but in GL2, vertex attribute 0 is the vertex
position. This too, is fair enough. The problem is, mesa is assigning 0 to
my vcolor attribute and thus I can't set it. The work around is simply to
swap the declaration order of vcolor and vertex (this really shouldn't work
eiter, I suspect).
 2011-12-28 20:43:56 +09:00

As I need to control the alpha, they're sent as rgba rather than quake

textbox, crosshair, tileclear, fill and fadescreen are the remaining

Add GLSL directory to QF and use it for all gsls based code (instead of
GL). defines.h, types.h and funcs.h are derived from gl2.h from khronos.

Text drawing now uses triangles instead of quads.

55a0ed49cd Build qw-client-glslx too. 
I was asked about timedemo overkill (bigass1 currently gets 40kfps, haha),
so I had to add qw-client-glslx to the build.
 2011-12-25 16:41:14 +09:00

Bill Currie
99c490ce52 Get glsl running as a null renderer. 
This means that nq-glslx can get through demo1, demo2, demo3 and bigass1
without crashing. However, nothing is rendered, so unless you like black,
it's not very interesting.
 2011-12-25 13:02:26 +09:00

min/max bound into mathlib.h (they /are/ math functions, after all) and
field_offset into qtypes.h.
 2011-12-24 10:04:33 +09:00

nq-glslx almost links. Just some suspicious references in host.c I want to
check before doing anything more.
 2011-12-23 12:19:50 +09:00
Bill Currie
497461b4c2 Make a start on making a pure GLSL renderer. 
For now, only nq-glslx will be built, but as there is no actual code, it
doesn't link. However, this gets the glsl stuff into the build system.

 2011-12-17 19:42:19 +09:00
Bill Currie
87b78e5533 Move the surface chain links out of the surfaces. 
The links are now in "instance surfaces". For non-instanced models (world,
doors, plats etc (ie, world and its sub-models)), there will be one
instance surface per model surface. However, for instanced models (ammo
boxes etc), there will be many, dynamically allocated (not yet
implemented). This commit gets the static instance surfaces working.

Bill Currie
3eb859a88f Move the entity transform setup into the clients. 
This has several benifits:
  o The silly issue with alias model pitches being backwards is kept out
    of the renderer (it's a quakec thing: entites do their pitch
    backwards, but originally, only alias models were rotated. Hipnotic
    did brush entity rotations in the correct direction).
  o Angle to frame vector conversions are done only when the entity's
    angles vector changes, rather than every frame. This avoids a lot of
    unnecessary trig function calls.
  o Once transformed, an entity's frame vectors are always available.
    However, the vectors are left handed rather than right handed (ie,
    forward/left/up instead of forward/right/up): just a matter of
    watching the sign. This avoids even more trig calls (flag models in
    qw).
  o This paves the way for merging brush entity surface rendering with the
    world model surface rendering (the actual goal of this patch).
  o This also paves the way for using quaternions to represent entity
    orientation, as that would be a protocol change.

b05be59ea0 Fix alias models in non-mtex fog. 
It turns out that due to the way we do fullbrights, nothing special needs
to be done to get the fullbright texture blended with the model even when
fog is enabled.
 2011-12-12 17:08:22 +09:00

8e531a58c2 Get global fog working for multi-pass rendering.

91e65b6c80 Rename mplane_t to plane_t and clean up the mess. 
I got rather tired of there being multiple definitions of mostly compatible

c4f71c0cda Move r_skyname handling from R_NewMap to R_LoadSkys. 
r_skyname now acts as the default sky to use when no sky name is specified
by other means ("none" is still no sky). 'loadsky foo' will load the
"foo*" sky textures, 'loadsky none' gives the default sky, and 'loadsky
""' causes uses r_skyname.

Bill Currie
085b0f4448 Remove R_SplitEntityOnNode2 
When R_AddEfrags is used (as is the case in nq), this function is
redundant. Brush models in qw are currently broken (invisible), but that's
just a matter of getting qw to use R_AddEfrags instead of R_NewEntity.

This removal should speed up the software renderers a little bit.

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.

c2c3a62956 nuke Qexpand_squiggle. instead, expand ~ to $HOME on qfs initialization and 
cache the value.

don't call Qopen directly in the engine. instead call QFS_Open (generic) or
QFS_WOpen (write only, zip flag).

rework QFS_NextFilename to use a dstring (avoiding a potential buffer
overflow), support 10000 files and work from the top-level fs_userpath
directory. adjust QFS_WriteFile and QFS_WriteBuffers etc to suit.

make sw32 screenshots actually get written.

hopefully everything gets written to the right places :)

b7900a2c43 Undo snax's order of operation breakage, and fix the typo that broke lightmap merging for r_lightmap_components 1. 
The real problem with greyscale lighting, is in brush model loading. It'll probably take me a while to sort it out, since taniwha didn't get to it before taking off for the weekend. Sorry...

ff901a312f Added argument-list functions to EXP with trig and inverse trig functions 
to start.  More will follow.  Switched to doubles from floats and allowed
numbers with exponents to be parsed properly.  Also changed the number of
significant digits printed to 10.  Changed fov so it is now capped at 1,
not 10.  The float value of fov is now used instead of int, so more
precision can be attained at small values.

5b069de40c Redo r_wateralpha so that it doesn't force its value based on the watervis 
serverinfo. Instead, create a new cl_wateralpha float variable that is set to
r_wateralpha->value in Host_Frame, and use that float during rendering.

da994c16e5 rewrite R_SplitEntityOnNode to be itterative rather than recursive (using 
a static `stack') to avoid the function call overhead. this cuts about 40%
of the execution time from this function.

No matter what I tried, best results were obtained using __builtin_expect,
so make sure non-gcc compilers do the right thing when they encounter it.

a4f3973ef1 Add multitexture support for Alias models, and disable the multitexture 
support for BSP models, until they can be fixed. gl_multitexture should now
actually be a speedup!

NOTE: Some OpenGL implementations have trouble with the texture function
used. 3Dfx Voodoo 1/2 are known to have this trouble. I don't know how to fix
this, or even if it can be fixed. :/
