0005c97865 Temporary weaks so things look halfway decent.
GL mipmaps and paletted textures don't mix, and lightmaps work quite well
with linear sampling.

12fd6bd390 Fix the segfault on map change.
I had forgotten to call R_ClearTextures when I'd rearranged the code.

f658e6c32e Initialize d_lightstylevalue.
"Let there be light!", but chaos still reigns (broken lightmap updates).

1229d24ef6 Get world rendering mostly working.
Just some problems with lightmaps. There also seem to be some issues with
seams (t-junctions?) and far clip, but they're quite separate.

There's also a problem with a segfault when loading a second map.

6abaa5ea74 Build the display list for all loaded brush models.
The entire vertex set from every model is put into one list (not yet
uploaded). chains of elements arrays are build for non-instanced models
(instanced models will have their chains built each frame).

fa82c37bd0 Pre-invert subpic->size.
I forgot to do this earlier :/

601cc6e3d1 Make a start on bsp rendering.
Still nothing being rendered: still in the process of building the display
lists, but I'm making good progress. Get this into git before something
goes wrong :)

29a0dc0b68 Actually build the lightmaps, and fix a silly bug in the scrap allocator.
Also, add a command for dumping scrap statistics.
2012-01-07 15:35:08 +09:00

8a5658ed61 Implement the bulk of the lightmap code.
Now just to get surface rendering going and hook in the lights.

0993803006 Add texture sub-image management.
The planned uses are lightmaps and 2d icons.

2ae044effd Split out vrect_t to its own file and add support functions.
The rest is cleanup after removing a wart from one of the field names.

423e08ce21 Add demo to "movie" conversion.
It currently writes a series of png files (QF/qfmvNNNNNN.png), at a fixed
rate of 30fps, with no sound recording.

b13a2b6dbd Move screenshots to $fs_userpath/QF.
I got tired of screenshots getting scatter across the tree. ShotsPath in
the dirconf can override this.

297a4e2756 Put the D_FlushCaches mess back.
It turns out that when it is called is highly timing sensitive :(
However, the rest of R_ClearState remains.

6f18035c12 Fix up alias-16 support.
After getting in contact with serplord, I now know that the sw alias
loading was correct. Turns out the gl loaders was mostly correct, just a
mistaken subtract rather than add. And with that, I can implement alias-16
support in glsl. better yet, since all the work is done in the loader, the
renderer doesn't know anything about it :) However, I need to create some
16-bit models for testing.

c6bcd7aedb Normalize the vertex normals.
I was wondering why the lighting looked a little extreme in overkill.

8fbc6221f7 Get sprite interpolation working.
It's not perfect (it can't be), but it looks a whole lot nicer than no
interpolation.
2012-01-04 18:31:35 +09:00
Bill Currie
6050901e0e Break out the entity blend calculations.
This allows alias and sprite model lerping to share the code.
2012-01-04 18:30:47 +09:00

836209e5c6 Enable lerping of alias models.
Done in hardware }:>

f0e88bbe85 Rip out the duplicate lerp code and merge it.
While the vertex lerping needs to be duplicated in the current GL code,
there's no need for the setup code to be duplicated. Also, I want it for
GLSL.
2012-01-04 16:26:52 +09:00
Bill Currie
99381b8b8c Rework the alias vertex shader and rendering code for lerping.
Lerping isn't actually done yet (need to get both poses and blend), but
this still renders correctly with blend forced to 0.0.

add5440ad1 Upload the normals with the vertex data.
Not all hardware can access a texture sampler from the vertex shader, and I
don't want multiple paths this early in the game. Now, vertex normals are
uploaded as shorts. Should be 14 bytes per vertex (was 10, could have been
8 if I had put the normal index with the vertex rather than st).

fea7acd871 Enable vis calculation.
One nice thing about this project: I now KNOW that efrags works the way I
wanted it to: all those torches are now toggleable via r_novis :)

Bill Currie
0797183201 Merge R_MarkLeaves from gl, sw, and sw32.
Other than novis, they're functionally identical. Now sw and sw32 have
novis as well.

091b714e4c Implement dynamic lighting.
This uses the same calculations as the software renderer. However, as the
lightmap calculations are not done yet, if there is no dlight in the
vicinity, there will be no light. demo1 is pretty cool to watch :)
2012-01-03 20:36:07 +09:00
Bill Currie
209c4cda8b Scale the light level index correctly before colormap lookup.
With this, lighting seems to be working. I'm not certain the normals are
100% correct, but I can see something happening on rotating models.

e8f863c76f Remove the hedgehogs from the garden.
While the first frame was fine, any subsequent ones were not. I had
forgotten that hdr->poseverts held the edited vertex count rather than
hdr->mdl.numverts.

d7bc437e2c Fix the borked texture coordinates.
Silly me, doing byte based pointer math on a non-byte pointer :P
2012-01-03 18:10:35 +09:00

185fded944 Re-enable the matrix optimizations.
Turns out my concatenations were correct.
2012-01-03 18:09:33 +09:00
Bill Currie
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
2012-01-03 18:08:01 +09:00
Bill Currie
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.
2012-01-03 18:06:26 +09:00

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

Bill Currie
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.
2012-01-03 09:34:17 +09:00

c378acab6b Actually load up the mvp and normal matrices.
Rather critical. I thought I'd done that :/
2012-01-03 09:34:17 +09:00

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.
2012-01-02 17:47:22 +09:00
Bill Currie
1c480bf75e Merge the alias skin selection code.
We really don't need 4 copies of identical code when 1 will do :P

df3d9fe4df Correct the fullbright start color extraction.
I don't know what despair and I were thinking, but we obviously didn't
understand the colormap code at the time.

7be08534be Clearify the program dump info a little.
Calling programs shaders was a little confusing when I use shader to refer
to the sub-programs (vertex and fragment shaders). Also, print the program
number as well.
2012-01-02 10:22:03 +09:00
Bill Currie
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.

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
Bill Currie
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
Bill Currie
9fec4d5be0 Implement Draw_Fill.
Almost there with 2d.
2011-12-29 11:25:27 +09:00

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).
2011-12-28 20:43:56 +09:00
Bill Currie
6a44978a0f Fix reading of GL_CURRENT_VERTEX_ATTRIB.

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

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)

f78db6c570 Clean up the generated shader files. 2011-12-26 16:39:02 +09:00
Bill Currie
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.
2011-12-25 19:42:39 +09:00
Bill Currie
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
9df7370bcd Create some shaders for quake text.
Still nothing drawn, but this gets my shader scripts into C without me

b7c90fa02d Load the quake palete as a texture.
256x1 rgba.
2011-12-25 13:53:52 +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.
