Bill Currie 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.

Bill Currie 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.

Bill Currie 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.

Bill Currie 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.

Bill Currie bf38e6073e Implement iqm joint loading. 2012-05-15 21:08:44 +09:00
Bill Currie 9f253454e4 Implement and test Mat4Inverse(). 2012-05-15 21:08:44 +09:00
Bill Currie 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 1473dbd526 Add a comment about the evaluation order in VectorShear. 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 :)

Bill Currie 82abd5e426 More matrix tests. 2012-05-15 21:08:44 +09:00
Bill Currie 730f9668bd Add support for mat4 * vec3 2012-05-15 21:08:44 +09:00
Bill Currie 50af8a562e Add tests for matrix decomposition and fix the bugs. 2012-05-15 21:08:44 +09:00
Bill Currie 724427a976 Add component-wise vector and quaternion division.
Mostly for non-uniform scaling.
2012-05-15 21:08:44 +09:00
Bill Currie 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).
2012-05-15 21:08:44 +09:00
Bill Currie 1be9384f10 Load the iqm vertex and triangle data.
Still have the meshes, joints and animations to go.
2012-05-15 21:08:43 +09:00
Bill Currie 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.
2012-05-15 21:08:43 +09:00
Bill Currie f874aeb941 Add support for duals and dual quaternions.
Not everything is unit-tested, but the currently important stuff is.
2012-05-15 21:08:43 +09:00
Bill Currie 26a878da48 Stub out the iqm loader. 2012-05-15 21:08:43 +09:00
Bill Currie f9a384ffd4 Make simple gravity acceleration framerate independent.
Now it doesn't matter if you get 22 fps or 72, you jump the same height,
which actually happens to be slightly higher than the previous 72fps jump.
Effectively, you jump the height you would if you got infinite fps ;)
2012-04-28 14:54:58 +09:00
Bill Currie 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.
2012-04-26 20:55:11 +09:00
Bill Currie 1a0ccf6a92 Add vec = quat * vec to the progs engine. 2012-04-26 11:58:20 +09:00
Bill Currie 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*).

Bill Currie 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 87e56e0655 Fix some doxygen issues. 2012-04-22 22:20:45 +09:00
Bill Currie bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.
2012-04-22 10:56:32 +09:00
Bill Currie 7fc700b802 Allow alias textures up to 1024x1024.
Blender's default texture size is 1024x1024, and there doesn't seem to be
any reason not to support it.
2012-04-15 14:13:05 +09:00
Bill Currie 633f70b2f1 Remove a functionally dead symbol.
The only purpose clearnotify seemed to be serving was to stop the console
plugin from loading :P
2012-04-12 17:05:42 +09:00
Bill Currie 7fc99f9c60 Fix gl and glsl support in sdl. 2012-04-12 16:47:37 +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...
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 1d864521e9 Fix the sprite model loader for plugins. 2012-04-11 14:58:55 +09:00
Bill Currie cbdbfdd12f Fix the alias model loader for plugins. 2012-04-11 14:58:55 +09:00
Bill Currie 52e518bb1b Fix skin functions for plugins. 2012-04-11 14:58:55 +09:00
Bill Currie a093e6af97 Move palette setting into viddef_t. 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 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 :)
2012-04-11 14:58:55 +09:00
Bill Currie 7865f6afe1 Rename sw's R_Init to sw_R_Init.
For now, the only symbol I'll bother messing with in the sw renderer.
2012-04-11 14:58:54 +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 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 :)
2012-04-11 14:58:54 +09:00
Bill Currie d445b4ef88 Rename the glsl qfgl functions to qfegl.
Keep them separate from the gl renderer :)
2012-04-11 14:58:54 +09:00
Bill Currie 36504547a8 Rename the public symbols for gl, glsl and sw32.
Evil hack, but it does the job.
2012-04-11 14:58:54 +09:00
Bill Currie 8de5c9ae3f Do a final cleanup before doing the big rename. 2012-04-11 14:58:54 +09:00
Bill Currie f7007825e4 Run the vacuum cleaner over sw32's global variables.
This seems to be everything that can be made static.
2012-04-11 14:58:54 +09:00
Bill Currie e991c1fed3 Make a bit of progress cleaning up vid for plugins. 2012-04-11 14:58:54 +09:00
Bill Currie 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.
