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.

e27d7cbd2d Handle alloca "correctly". 
Use AC_FUNC_ALLOCA and the #ifdef mess suggested by the autoconf docs
(hidden in qfalloca.h).

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).

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.

4a95f89760 Correct the handling of r_viewsize and lineadj. 
r_viewsize is meant to be clamped to 100, but not limit linadj.

86b95629cf Complete the move of some vars into vid_render_data. 
scr_fullupdate and scr_copyeverything were missed. Possibly others too, but
this is enough for the moment.

82a6861233 Move the call to VID_Update out of the if blocks. 
This makes it obvious that VID_Update is unconditionally called when
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)

They seem to not be needed any more.

9758302023 Fix sw and sw32's R_RecursiveWorldNode node stack. 
I guess I had forgotten to make the node stack dynamically allocated for
these renderers. Now ITS works in all four renderers.

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.

433d9d138b Hook up the pointfile loader in glsl. 
I was always wondering what that was for (never bothered looking at the
command registration, I guess :P).

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.

5b054dd98b Add "slow grav" for smoke. 
Removes one more set of hard codings from particle types.
 2012-08-12 11:42:18 +09:00
Bill Currie
5a5b31bae4 Correct the direction of pt_fire particles. 
sub_grav() was accelerating the particle in the wrong direction. Down being
+ve gravity caused a bit of confusion (though it was a c&p error).

372defc1be Support up to 128 dlights. 
More or less as per MH's tut, but really just finishing something that
should have been done years ago.
 2012-07-21 13:58:54 +09:00

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
Bill Currie
c4309e7abc Correct the fog blend calculation for transparency. 
The incoming pixel's alpha should not be affected by fog. This fixes the
ugly square smoke particles in foggy maps.

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...
the shadow code expected triangle fans and strips but was getting simple
triangles. Oops.

8333e6578c Fix non-static sw renderer for 32bit x86.

asm/not asm.

f9c6eacb84 Really fix sw32 renderer loading. 
It seems I never tested the sw32 renderer in a non-static build since I put
in IQM support.
 2012-07-15 07:30:17 +09:00
Bill Currie
fd6b5edb73 Don't set triangle draw type in sw32 iqm renderer. 
It's not used and causes link errors (I never noticed on my system).
 2012-07-14 19:48:57 +09:00

6fe32103ea Do a bit of bound() usage auditing. 
While these seem to be mostly harmless, having function calls in the
bounded value can be nasty.

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.

Yay, no more garbage on the screen :)
 2012-07-09 15:56:51 +09:00
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).

37260018a2 Acutally use the vertex colors for alias models. 
Thanks to Spirit trying QF on nvidia drivers, the missing attributes were

ee1cb24e3d Move the call to R_SetFrustum to gl_R_SetupFrame. 
This was meant to be part of the previous commit, but I forgot to write the
file :P
 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 :)
 2012-07-03 15:57:33 +09:00

e58cd75660 Bound r_maxdlights properly.

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).

e170f4ee75 Slightly reducde the number of calls to glUniformMatrix4fv. 
It doesn't make a big difference to bigass1 (yet ?), but it does clean up
apitrace a little.

1a6b56b0a2 Call glTexSubImage2D only once per frame. 
Instead of once per surface... ouch. Gives about 20% speed boost on demo1
(154.7->185.7)
 2012-07-02 20:01:28 +09:00
Bill Currie
4da3be5cd6 Get a minor speed gain in glsl bsp rendering. 
About 4% (99.5 to 104.4) from not calling VertexAttrib4fv or BindTexture
when not necessary.

be9c0697a2 Give sw iqm its own transform setup. 
IQMs don't need to be scaled or offset. This fixes iqms not rendering,
though they actually were: just super tiny.

c0517b1d97 Factor out the blend palette creation. 
gl, sw and sw32 use blend palettes, so share the code. This also abandons
the optimization for transforming verts in sw (had all sorts of problems
anyway). sw still doesn't work, though.

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

Problems:

It was there only because mrfixit is rather small (8qu?) and it made

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.

a938c7fb14 Almost fix the animations. 
There's still a problem with his finger tips and feet, but the rest of his
limbs seem to be working well. Much thanks to Spike for encouraging me to
do a dump of the matices that are actually sent to the card.

It turns out that animated joints remain relative right up to the last
moment.

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.

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.

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

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.

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.

d62772e9cc Separate render module loading from initialization. 
This allows the vid module to load the render module and access render

an initialized vid module...

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.

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

the particles.

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.

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

3669e3aa2e Make alias model caching optional.

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.

Vertex locations need to be unsigned byte rather than byte (GL is funy

test tetrahedrons seem to be working.

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).

8ee13ef8c2 Do some clipping in the draw routines. 
After fixing Maraakate's crash, I thought it would be a good idea to put
the fixes into QF, too.

151cc05882 Add support for vertex colors. 
As I need to control the alpha, they're sent as rgba rather than quake
palette indices. Text works well. All other 2d stuff does not :(.

b943b6d6e8 Implement crosshairs, mostly. 
Colored crosshairs aren't supported yet (next).

db8573b774 Make the cross-hair data sharable between renderers. 2011-12-26 21:43:15 +09:00
Bill Currie
705d07fa39 Implement most of the 2d rendering functions. 
textbox, crosshair, tileclear, fill and fadescreen are the remaining
functions.

There's a problem with 2d icons being drawn over the text (instead of
under), but I'll leave that for later.

42034acc03 Organize the text program data. 
Also, rename the charmap uniform in quake2d.frag as it's more generic than
that.
 2011-12-26 18:00:55 +09:00

2ccfbb0c1c Move the shader program code into vid_common_glsl. 
Much more useful in the long run.
 2011-12-26 17:17:29 +09:00

5bed38dcd9 Rename quaketxt.frag to quake2d.frag. 
It's actually fairly generic for 2d rendering (no lighting, palette lookup)

d743c6c55f Make a clean break heading for GLES compatibility. 
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.

7bd5ab882c Get text rendering working. 
It comes out as a funky green (that's not in the quake palette!!!), but
it's mostly readable.

9f5eacd1fb Try to get text rendering. 
Still a black screen :(

7d653f3676 Start work on outputting text. 
The shaders now compile. No linking is done yet. Char quads are generated,
but not sent to the card.

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

9df7370bcd Create some shaders for quake text. 
Still nothing drawn, but this gets my shader scripts into C without me
having to look at ugly strings.

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.

cc5140e3a1 Move min/max/bound and field_offset into better locations. 
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

6fe9557dae Put in the final pieces so nq-glslx can link. 
Everything is still stubs. Trying to run nq-glslx results in a segfault :)

53d89bf85a Clean up the mess around D_FlushCaches. 
Create an R_ClearState and call that from the clients. It calls any
necessary functions itself.
 2011-12-23 12:51:47 +09:00
Bill Currie
33c5320c0e Create stubs for most of the required render functions. 
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.

52d9269867 Merge brush model with world model rendering. 
With this, non-mtex global fog now works properly :).

a8e354536a Implement the instance surface allocation/freeing. 
Not actually used yet, so it's harmless at this stage.
 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
962451e2fe Create a list of texture chains. 
This moves the texture chains out of the world model and into a separate
list, allowing other brush models to registter their textures.

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.

4b515a961b Back out the fitzquake lerp changes.

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
Bill Currie
8e531a58c2 Get global fog working for multi-pass rendering. 
For the world textures, anyway. Entity multi-pass rendering still needs to
be verified.
