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.

0becd35b65 Begin work on rendering iqm models.
No chance of working yet, but the shaders compile :)

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.

9a3206795e Add VectorUnshear().
VectorUnshear uses the exact same shear vector to remove shear from a
sheared vector. ie with:
  VectorShear (shear, v, w);
  VectorUnshear (shear, w, x);
x == v within fp math limits.

fa6270322f Make Mat4Decompose a little more intuitive.
Params are now in application order (good thing not much code uses it yet).

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 :)

724427a976 Add component-wise vector and quaternion division.
Mostly for non-uniform scaling.
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).

1be9384f10 Load the iqm vertex and triangle data.
Still have the meshes, joints and animations to go.

890223ef8e Correct the definition of DualQuatNorm.
I'd gotten the norm and magnitude mixed up (partly because the document I
was following got the names mixed up), and then munged the formulas
together.

f874aeb941 Add support for duals and dual quaternions.
Not everything is unit-tested, but the currently important stuff is.

26a878da48 Stub out the iqm loader. 2012-05-15 21:08:43 +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.

1a0ccf6a92 Add vec = quat * vec to the progs engine. 2012-04-26 11:58:20 +09:00

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.

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

633f70b2f1 Remove a functionally dead symbol.
The only purpose clearnotify seemed to be serving was to stop the console
plugin from loading :P

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.

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

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...

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.

e08d5ccb41 Move the gl util functions into viddef_t.
Static plugins almost link now, just two more symbols to sort out.

7ed33f6345 Hide D_FlushCaches.
There'd been a way to do so all along :/ There might be some issues with
this, but those will be easy to fix :)

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

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 :)

d445b4ef88 Rename the glsl qfgl functions to qfegl.
Keep them separate from the gl renderer :)

36504547a8 Rename the public symbols for gl, glsl and sw32.
Evil hack, but it does the job.

96b80433d8 Make some progress in getting static plugins to link.
Still many redefined symbols (and I expect more to come), and many
undefined symbols too.

ad61c7a30c Start working on creating the render plugins.
Things blow up quite nicely. :)

8e91fb7bc1 Get the basics linking.
Still, nothing will work: no plugins are loaded and they're all broken
anyway.

glx, sgl, glslx etc are going away, just the basics will be built: fbdev
(probably go away eventually), sdl, x11 and hopefully someday win. That's
actually the only reason anything links.
