21c7b84379 Enable face culling and depth testing.
I spent way too long trying to figure out why triangle order wasn't making
any difference... :P

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.

62e564c5cd Send ALL of the model's verts to GL.
Triangles have 3 vertices, not one :P

ba04cf73d0 Add my test tetrahedrons. 2012-01-03 09:34:17 +09:00
Bill Currie
baab15279f Correct the alias vertex data types.
Vertex locations need to be unsigned byte rather than byte (GL is funy
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.

c378acab6b Actually load up the mvp and normal matrices.
Rather critical. I thought I'd done that :/

86edf54c40 Build and ignore cleanups
GLSL renderer build was checking for BUILD_GL instead of BUILD_GLSL in a
few places. Also, ignore the GLSL .fc and .vc files and the binaries.

2a3151cecd Hook in alias model drawing.
Nothing is visible yet.

72e3a8d507 Merge sw and sw32 alias frame selection.
I'm leaving GL for later because lerping complicates things. I'll sort it
out when I implement lerping in GLSL.

1c480bf75e Merge the alias skin selection code.
We really don't need 4 copies of identical code when 1 will do :P
2012-01-02 15:57:43 +09:00

I had forgotten I wanted to do it this way.

d1419c30db Make a start on alias model rendering.
The vertex and fragment shaders are written, and R_InitAlias is stubbed,
but that's it so far.

718595db45 Implement sprite rendering.
Sprite interpolation seems to work, even :) (maybe)
2011-12-31 14:39:33 +09:00
Bill Currie
091e16f9d2 Bring in GL's R_RecursiveWorldNode as R_VisiteWorldNodes.
No surface queuing is done, but entities get queued.
2011-12-31 14:33:20 +09:00
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
mention it, but it looks like blending between the sprite frames' verts is
necessary too.

a87a60a6fd Flush the text buffer before drawing conback or menus.
Ok, now really done until I notice something else (I forgot this one
momentarily).
2011-12-29 18:23:09 +09:00

047b7bcc32 Implement Draw_TileClear.
With this, 2d seems to be finished. YAY.
2011-12-29 18:15:15 +09:00

a1035aafe9 Implement Draw_TextBox. 2011-12-29 17:51:31 +09:00
Bill Currie
2b44a25c6b Flush console text after each screen function.
This on its own doesn't fix menus being overwritten with console text, but
it's an important step.
2011-12-29 11:26:14 +09:00

9fec4d5be0 Implement Draw_Fill.
Almost there with 2d.

bece72e746 Use a quick hack to get colored crosshairs working. 2011-12-28 21:45:20 +09:00
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).

b657905c83 Bring in Despair's gl error checking from the gl renderer. 2011-12-28 09:05:36 +09:00
Bill Currie
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 :(.
2011-12-28 09:04:26 +09:00

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

Bill Currie
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
Bill Currie
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
Bill Currie
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.
2011-12-26 16:08:55 +09:00

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

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.
2011-12-25 15:53:12 +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

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
Bill Currie
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.

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.

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.

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
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.

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.
