0fbaa2a88a Add sw32 support for iqm models.
That was easy :)

3087e685cc Convert texcoords to fixed point.
Bah, another weekend wasted on an oversight :( However, Mr. Fixit looks
quite alright in the quake palette.

f0285e5a08 Correct the texcoord conversion.
1.0 is to represent the last pixel, not one past it.

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.

c1eb3e77c3 Process each vertex texcoord only once.
Double converting texcoords results in 0,0 for all affected texcoords. Mr
Fixit was looking rather ill. Now he looks weird (something wrong in the
renderer?).

d41bf32d91 Hopefully fix color conversion.
Hard to tell because the triangle rendering is still messed up. However,
storing negative values in bytes doesn't work :)

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.

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.

da87ac0ce5 Remove some unused parameters. 2012-05-17 21:33:22 +09:00

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.

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.

111377f1be Use buffer objects for iqm vertex arrays and elements. 2012-05-15 21:08:47 +09:00

5740dba467 Mark iqm models as need-load when clearing.
This fixes the segfault on map change.
2012-05-15 21:08:47 +09:00

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
Bill Currie
4ba69b511b Make quat_origin the right type.
It's quat_t, not vec3_t :P.
2012-05-15 21:08:46 +09:00
Bill Currie
202ab04572 Ensure the rotation quats are normalized.
Doesn't make any noticeable difference, but it doesn't hurt.
2012-05-15 21:08:46 +09:00
Bill Currie
31d89782ef Use the correct index variable when byteswapping the arrays.
Not the cause of the broken animations :(
2012-05-15 21:08:46 +09:00
Bill Currie
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
2012-05-15 21:08:46 +09:00
Bill Currie
d1d4c6142c Get the frame data from the right places.
Always using joint[0] of the frames wasn't very useful.

551dfc47fb Build the iqm vertex arrays in the correct order.
They need to be built in ascending type order (makes life easier in the
renderer).

2e98c31175 Check the corrent bits when reading scale frame data.

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.

0becd35b65 Begin work on rendering iqm models.
No chance of working yet, but the shaders compile :)
2012-05-15 21:08:45 +09:00
Bill Currie
078cb10caf Add a stride field to iqm_t.
Since iqm vertex arrays are variable, and I don't want to calculate the
stride every time I render a model, cached the value used when building the
arrays.

6ab3bd45e5 Implement IQM animation loading.
Bone poses are converted to dual quaternions + shear + scale for nice
skinning. Will likely be slow for software skinning, but too bad.

fa6270322f Make Mat4Decompose a little more intuitive.
Params are now in application order (good thing not much code uses it yet).
2012-05-15 21:08:44 +09:00
Bill Currie
de131c18ad Add VectorShear and really test Mat4Decompose.
And the tests really exercised VectorShear (first attempt had things
messed up when more than one shear value was non-zero). Also,
Mat4Decompose wasn't orthogonalizing the z axis row. Oops. Anyway,
Mat4Decompose is now known to work well, and the usage of its output is
understood :)
2012-05-15 21:08:44 +09:00

8cea6b0a1e Fix a scaling snafu in Mat4Decompose.
Found when checking how rotation affects non-uniform scaling (haven't
written proper tests yet: need to figure out how).

And correct an oopsie in bledweights.
2012-05-15 21:08:44 +09:00

215d2e9747 Add a function to decompose a matrix.
The function gives rotation(quaternion), scale, shear, and translation (all
three as vectors), shear is (XY, XZ, YZ).

e6c0512f31 Ensure dstring has space for terminating 0.
It seems (some versions of) windows vsnprintf don't count the terminating 0
when limiting the number of chars written to the buffer. Nor do they
guarantee the output string will be terminated.

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.

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

8791b35e55 Add support for half floats.
iqm and OpenGL use them, so they might come in handy. The tests use values
from wikipedia and a couple extra.

efaef89c5f Add a shortcut function for quaterion/vector multiplication.
I got the idea from blender when I discovered by accident that quat * vect
produces the same result as quat * qvect * quat* and looked up the code to
check what was going on. While matrix/vector multiplication still beats the
pants off quaternion/vector multiplication, QuatMultVec is a slight
optimization over quat * qvect * quat* (17+,24* vs 24+,32*, plus no need to
to generate quat*).

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.
2012-04-25 10:09:23 +09:00
Bill Currie
a7870a98a1 Apply a couple of patches from calim of nouveau.
One's an actual bug, the other a bit of error checking (not sure how
necessary it is, but it's in code that we don't /want/ to run, so it can't
hurt :)

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.

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.

3b07928373 Fix an inconsistent numeric constant.
While checking the shaders to see if there might be anything obvious to

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.

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

898bfa5e5f Split up the vid plugin init sequence.
This gets gl so it no longer segs. However, the screen remains black
