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.

2ccfbb0c1c Move the shader program code into vid_common_glsl.
Much more useful in the long run.

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.

Ooooops :P

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.

91afdcf064 Don't call init_box when not doing a box trace.
I took the opportunity to pass qf through callgrind. init_box was
surprisingly expensive, especially considering its results were never used.

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.

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.

b7c90fa02d Load the quake palete as a texture.
256x1 rgba.

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.

Just how many definitions do we need?

dcf2b14188 Implement alias model skin loading for glsl. 2011-12-25 13:02:26 +09:00

e62eb23f67 And do the real merge.
That drastically simplifies the processes of alias model loading for glsl :)

c0d37ddc1e Pseudo merge gl and sw Mod_LoadAliasGroup.
Interestingly, this didn't break gl alias model renderering (but then, it
does weird things to the data anyway).

1f8db5fe3a Pseudo merge gl and sw Mod_LoadAliasFrame. 2011-12-25 10:34:29 +09:00

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.

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.

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.

858d95de58 Add a bunch more keys to the X11 clients.
Now, QF does something reasonable for every key on my keyboar for which X
gives us a keycode.

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.

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.

933120d44f Fake vertex arrays for text and particles.
Getting gl_vaelements_max -1 to work produced a rather nasty surprise :P

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.

f6ebb78140 More GL_Init_Common() cleanup.
Move the call to GL_Common_Init_Cvars() out of the block of check calls.

51aaee5c3b Put that OpenGL error message to rest.
The error was quite valid: setting GL_TEXTURE_MAX_ANISOTROPY_EXT to 0 is
incorrect. The problem was caused by the call to glTexParameterf being
before the gl_anisotropy cvar was initialized. Thus, move all of the setup
code in GL_Init_Common() to after all the checks and, more importantly,
after the call to GL_Common_Init_Cvars().

da552e33e7 Remove execinfo checks.
It seems we no longer need it (if we ever really did).

4b515a961b Back out the fitzquake lerp changes.
That's not the direction I wish to take the renderer.

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.
