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

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

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 :)

e58cd75660 Bound r_maxdlights properly.
QF's implementation doesn't support more than 32 dlights (32 bit int).

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

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.

b2290d92c9 Nuke UNALIGNED_OK.

85da69a96a Transform normals wrt bones in sw and sw32.
Better lighting :), though any scaling/shearing will produce funny results,
and sw32's lighting is broken in general.
2012-05-20 15:21:25 +09:00

0fbaa2a88a Add sw32 support for iqm models.
That was easy :)
2012-05-20 14:23:41 +09:00

e2db2dcb63 Support static iqm models.
Segging on a model with no animations is not nice :P

d25f39cc7d Remove pskindesc from affinetridesc_t.
It's never used after being set.
2012-05-19 09:29:05 +09:00
Bill Currie
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.
2012-05-19 00:43:26 +09:00
Bill Currie
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.

fb10f38fd4 SW now tries (but fails miserably) to render iqm models.
Something seems to be very wrong with the transforms.

da313cfae7 Load iqm models in the sw renderers.
sw32 loses 32 bit textures :/
loading is /slow/ (converting rgb(a) to 8bit palette... ouch.
2012-05-17 21:17:48 +09:00

7637f35616 Remove the test scaling.
Heh, forgot to remove it again :)

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

Problems:
	rendered fullbright (no lighting done)
	normals are ignored
	extra textures (glow etc) not used/loaded

4 models on the screen don't seem to be a problem.
2012-05-17 15:58:29 +09:00

f958afad53 Optionally allocate extra data for iqm blend frames.
Also, correct the blend parameter type (int->float. oops).
2012-05-17 15:57:07 +09:00
Bill Currie
c0df07b607 Enable loading of iqm models in gl.
They don't render yet, but the engine doesn't segfault.
The vertex blend indices are rewritten with blend palette indices.
2012-05-17 15:55:38 +09:00
Bill Currie
041d63c828 Move the frame blending into common code. 2012-05-16 17:44:18 +09:00
Bill Currie
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.
2012-05-15 21:08:47 +09:00
Bill Currie
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).
2012-05-15 21:08:47 +09:00
Bill Currie
1375c3cf03 Finally, load textures for iqm :) 2012-05-15 21:08:47 +09:00
Bill Currie
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).
2012-05-15 21:08:47 +09:00

8c5e278bf8 Implement frame blending for iqm.
Now that I have things working... :)

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.
2012-05-15 21:08:46 +09:00

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.

9c69404163 Attempt to render iqm models.

41e7a6c70c Search for the "nearest" dlights.
Nearness is a function of both distance and intensity: distant bright
lights can take priority over close dim lights.

No chance of working yet, but the shaders compile :)

099d9ec3f2 Move the increment of order out of the loop.
I don't know what gcc's optimizations would do with it, but it seems quite
reasonable to pull the code out of the loop by hand.

cf5c9f067f Make GL_DrawAliasShadow const correct.
Despair's having troubles with segfaults that I can't reproduce. If it's a
strict aliasing problem, this might help.

a43bd755ca Fix the 32-bit x86 build of the software renderer.
I really need to remove the sledge-hammer approach, but this at least gets
QF working out-of-the-box on 32-bit x86 systems.
2012-04-28 13:02:36 +09:00
Bill Currie
20b7a46100 Remove a bogus model type check.
This allows 16-bit alias models to render when viewd straight on.

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.

bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

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.
2012-04-21 20:59:04 +09:00
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
Bill Currie
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...

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.
