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
found. Now he shouldn't get gl errors :)

Discovered while getting the location markers working again.

ef9e8d05c4 Avoid some unnecessary state changes.
Doesn't make much difference but it doesn't hurt.

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 :)

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).

df35b22af4 Parameterize the linear filtering of scrap textures. 2012-07-03 12:10:24 +09:00
Bill Currie
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.

8ada7c02a3 Remove the vertex scaling.
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.

0fd2b01665 Update the shader to work as it should :)
I always thought it whould be "light - point" :P. Also, in normal maps, 127
is 0.

c454b96d2a Translate lights into entity space.
Finally, lights work "properly". Probably the nicest lighting we've ever
had :) (still have to put in ambient, though).

1375c3cf03 Finally, load textures for iqm :) 2012-05-15 21:08:47 +09:00

a032aa5adf Get the lights working (as such).
They work nicely now when the normal map and texture are bypassed (don't
know what texture is getting used currently).

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.

7cda91a879 Temporarily disable dual quaternions.
The animation data isn't getting loaded or used properly (not sure yet).
This helps ensure it's not something I've done wrong with dual quats.

c2e0674d50 Implement R_IQMGetLerpedFrames().
Like R_AliasGetLerpedFrames, but for IQM. It calcualtes the current frame
number and blend between the previous and current frames.

099ef348c6 Advance the vertex attrib index.
Disabling the array right after enabling it was causing things to just not
work :P

d1d4c6142c Get the frame data from the right places.

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.

1fd84477a2 Rename char to dchar in the text vertex shader.
Thanks to Spirit :)

Turns out certain drivers (nvidia?) reserve "char" even though opengl does
not. This should fix his missing console text.

Bill Currie
3b07928373 Fix an inconsistent numeric constant.
While checking the shaders to see if there might be anything obvious to
work around the current nouveau shader issues, I found a 1 that should have
been a 1.0. I'm surprised it ever compiled.

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.
2012-04-12 14:40:02 +09:00
Bill Currie
8401704c4e Connect up palette setting for gl and glsl.
The GL plugin now seems to work. GLSL still segs :(
2012-04-12 13:57:05 +09:00
Bill Currie
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.
2012-04-11 22:45:23 +09:00
Bill Currie
898bfa5e5f Split up the vid plugin init sequence.
This gets gl so it no longer segs. However, the screen remains black
(expect for cshifts).
2012-04-11 16:44:38 +09:00

d62772e9cc Separate render module loading from initialization.
This allows the vid module to load the render module and access render
specific functions before the renderer initializes, which happens to need
an initialized vid module...
2012-04-11 14:58:56 +09:00
Bill Currie
6ea4e6617a Connect up viddef properly.
Or mostly so, anyway. sw32 is actually putting stuff on the screen.
2012-04-11 14:58:55 +09:00
Bill Currie
4d9c3408a1 Start putting the pieces back together.
The renderer now gets initialized and things sort of work (qw-client will
idle, though nothing is displayed). However, as the viddef stuff is broken,
it segs on trying to run the overkill demo.
2012-04-11 14:58:55 +09:00
Bill Currie
e08d5ccb41 Move the gl util functions into viddef_t.
Static plugins almost link now, just two more symbols to sort out.
2012-04-11 14:58:55 +09:00
Bill Currie
1dd1aec48f Make libgl_handle static.
This will make life interesting for getting the final stages working, but
it helps for now.
2012-04-11 14:58:54 +09:00
Bill Currie
772af29cb3 Move the gl cvars into gl.
That gets rid of the gl_overbrite_f clash. They were put in r_cvar for
saving to the config file, but that was before seta existed.
2012-04-11 14:58:54 +09:00
Bill Currie
65bd29353c Make a start on putting the pieces together.
Still many undefined and multiply defined symbols, but there seems to be a
light in this darkness. I just hope it's not an oncoming train :)

undefined symbols too.

ef37ed39a9 Clean up global symbols for the glsl renderer.
Where possible, symbols have been made static, prefixed with glsl_/GLSL_ or
moved into the code shared by all renderers. This will make doing plugins
easier but done now for link testing. The moving was done via the gl
commit.

78789a6833 Add support for blender's environment maps.
QF will now load a single image with (${skyname}_map.*) using blender's
layout. That is, 3x2 with the top row being back, right, front and the
bottom row being bottom, top, left.

4707706f5d Use QF_NEED for the renderer and model libraries.

f800e79a38 Make the init process more dependency based.
Most subsystems that depend on other subsystems now call the init functions
themselves. This makes for much cleaner client initialization (more work
needs to be done for the server).
2012-02-01 21:52:47 +09:00
Bill Currie
bc2aca53c3 Add functions to create/destroy qpics.
The creation uses raw 8-bit data (and the system palette). Destroying a
qpic loaded via other means will probably produce nasal demons.
2012-02-01 17:46:15 +09:00

706f09b247 Put the transparent surfaces on the water chain.
I'd actually done this the first time, but then got confused and forgot the
waterchain works with multiple textures. This is actually the right place
as all transparent surfaces need to be sorted irrespective to their
textures. Really, waterchain needs to be renamed.
2012-01-31 18:08:06 +09:00
Bill Currie
b286a35281 Sort transparent surfaces back to front.
This allows overlapping transparent surfaces to look like they are

b03e937b67 Implement brush entity alpha.

8f869c001b Fix the missing world on map reload.
If the map got reloaded but the current leaf didn't change the world (and
most entities) didn't get drawn. Forcing a vis update by first setting
r_viewleaf to null and marking surfaces does the trick :)

7e078c7f9c Revamp cshifts and implement in glsl.
The renderer should now be free of any direct access to client code. Even

7bfddd7ffe Gut most of the old skin code.
Custom skins are smashed on most targets. Player colors don't work, etc.
However, this will let me do a much cleaner implementation.

76cb60461d Tweak the size of point particles.
This looks fairly reasonable, but should probably be tweaked further to
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.
2012-01-21 21:54:36 +09:00
Bill Currie
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.

358bbc4439 Disable the sky spin effect.
It's cool, but not appropriate as a default. All that's needed is a way to

62c5070d8b Use the correct type for particle colors.
Sending byte data as floats doesn't work too well :P Fixes the colors of

2cb2f230fd Print out the point size range.
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.
2012-01-21 15:48:21 +09:00
Bill Currie
5e1a80e016 Implement particles as points.
Unfortunately, the maximum point size on Intel hardwar seems to be 1, so I
can't tell if the colors are right.

This is largely just a hacked version of GL's particle code.

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

fc43e5a307 Allow clearing of a scrap.
This "frees" all rectangles and subpics allocated from a scrap. subpics
