b5add680f7 Add Mat4as3MultVec.
to transform a vertex without the translation (eg, for normals) without
having to have separate matrices.

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.

da313cfae7 Load iqm models in the sw renderers.
sw32 loses 32 bit textures :/
loading is /slow/ (converting rgb(a) to 8bit palette... ouch.

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.

f958afad53 Optionally allocate extra data for iqm blend frames.
Also, correct the blend parameter type (int->float. oops).

02f8aa6b75 Add Mat4MultAdd macro. 2012-05-17 15:56:01 +09:00

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.

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).

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.

4ba69b511b Make quat_origin the right type.
It's quat_t, not vec3_t :P.

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

31d89782ef Use the correct index variable when byteswapping the arrays.
Not the cause of the broken animations :(

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.

4b38048a5c Create functions for rotation and translation. 2012-05-15 21:08:46 +09:00

5b4fdd2a93 Use the correct position for light calcs.
I should have remembered that gl_FragCoord wasn't right.

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

8387d987e2 Change position to vposition. 2012-05-15 21:08:46 +09:00

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.

74cb49ef7c Free the blended frame data. 2012-05-15 21:08:45 +09:00

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).

bea8f8f9c4 Fix a segfault when searching for dlights.
Uninitialized var bites my bum :P

2e98c31175 Check the corrent bits when reading scale frame data.
Fixes the invalid reads when loading an iqm (at least for mrfixit).
