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.

23284536b5 Move IQM freeing into common code. 2012-05-16 18:09:44 +09:00

111377f1be Use buffer objects for iqm vertex arrays and elements. 2012-05-15 21:08:47 +09:00
Bill Currie
5740dba467 Mark iqm models as need-load when clearing. 
This fixes the segfault on map change.

1375c3cf03 Finally, load textures for iqm :) 2012-05-15 21:08:47 +09:00

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.
 2012-05-15 21:08:46 +09:00
Bill Currie
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).
 2012-05-15 21:08:45 +09:00
Bill Currie
2e98c31175 Check the corrent bits when reading scale frame data. 
Fixes the invalid reads when loading an iqm (at least for mrfixit).
 2012-05-15 21:08:45 +09:00
Bill Currie
a880f33152 Set the model type for iqm. 
Forgot this rather important step :P
 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.
 2012-05-15 21:08:45 +09:00
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.
 2012-05-15 21:08:45 +09:00
Bill Currie
bf38e6073e Implement iqm joint loading. 2012-05-15 21:08:44 +09:00

8530959752 Link the model libs to the render plugins. 2012-04-11 14:58:53 +09:00
Bill Currie
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.
 2012-04-11 14:58:53 +09:00
Bill Currie
a4c280f2b2 Take the first step towards render plugins. 
No clients link. Even if they did, nothing would work.
 2012-04-11 14:58:53 +09:00
Bill Currie
39e1ccc506 Don't try to process skins in GL without a player model. 
If the client receives a skin updated message from the server before having
loaded the player model (shouldn't happen, but some servers have very
strange programmers), no skin data is avaible for updating, so just bail
out.

ef37ed39a9 Clean up global symbols for the glsl renderer. 
Where possible, symbols have been made static, prefixed with glsl_/GLSL_ or
moved into the code shared by all renderers. This will make doing plugins
easier but done now for link testing. The moving was done via the gl
commit.

4707706f5d Use QF_NEED for the renderer and model libraries. 
This breaks RPM building, but I can fix that later.
 2012-02-10 13:29:45 +09:00
Bill Currie
9fbff2f4d5 Do an audit of the Makefile.am files. 
o All instances of LIBADD/LDADD have a corresponding DEPENDENCIES
    specificatiion.
  o libraries now use a lib_ldflags macro to keep things consistent
  o duplication of source/lib names has been minimized (particularly in
    the libraries; more work needs to be done for the executables)
  o automake spec blocks have been organized (again, more work needs to be
    done for the executables)

497718cc40 Plug the memory/texture/vbo leaks. 
QF still leaks about 3MB/run on demo1, but even 100 runs didn't show any
render issues.

8ac9ff0134 Link libQFmodels* agains libQFimage. 
This is the correct fix for server linking wrt LoadPCX. Sort of. Really, it
would be better to disconnect the dependencies.

Bill Currie
7bfddd7ffe Gut most of the old skin code. 
Custom skins are smashed on most targets. Player colors don't work, etc.
However, this will let me do a much cleaner implementation.
 2012-01-23 16:16:30 +09:00
Bill Currie
3669e3aa2e Make alias model caching optional. 
For now, only the glsl loader disables caching, but it stores the frame
vertices in GL memory, so its hunk usage is relatively lower (and will be
lower still when I get skins sorted out).

7ba7130f42 Load the sky texture as two separate textures. 
The sky texture is normally 256x128, with each 128 wide side being the two
layers of the sky.
 2012-01-11 21:09:57 +09:00
Bill Currie
b43d03a98b Let the render specific texture loader decide on sky texture loading. 
This is necessary to allow the glsl texture loader to process the sky
textures.

6f18035c12 Fix up alias-16 support. 
After getting in contact with serplord, I now know that the sw alias
loading was correct. Turns out the gl loaders was mostly correct, just a
mistaken subtract rather than add. And with that, I can implement alias-16
support in glsl. better yet, since all the work is done in the loader, the
renderer doesn't know anything about it :) However, I need to create some
16-bit models for testing.

add5440ad1 Upload the normals with the vertex data. 
Not all hardware can access a texture sampler from the vertex shader, and I
don't want multiple paths this early in the game. Now, vertex normals are
uploaded as shorts. Should be 14 bytes per vertex (was 10, could have been
8 if I had put the normal index with the vertex rather than st).

91afdcf064 Don't call init_box when not doing a box trace.

c0d37ddc1e Pseudo merge gl and sw Mod_LoadAliasGroup. 
Interestingly, this didn't break gl alias model renderering (but then, it
does weird things to the data anyway).

33c5320c0e Create stubs for most of the required render functions. 
nq-glslx almost links. Just some suspicious references in host.c I want to
check before doing anything more.
 2011-12-23 12:19:50 +09:00
Bill Currie
497461b4c2 Make a start on making a pure GLSL renderer. 
For now, only nq-glslx will be built, but as there is no actual code, it
doesn't link. However, this gets the glsl stuff into the build system.

8aa5a8139c Split out the portal sanity tests.

9f32004599 Add a fixme. 
I've had enough of this for the moment, but I'm pretty sure the test needs
some more consideration, and I'll probably forget about it if I don't mark
it.
 2011-12-07 17:27:13 +09:00

66dffef936 Get trace_to_leaf working a little better. 
I think the recursion decision needs a little more work, but this gets the
current tests working (though there's still a failure due to fp math).

4f13d19b7e Optimize edges_intersect(). 
I found wolfram's line-line intersection page and noticed their equation
for the time of intersection was rather different to mine. After analyzing
the differences, it turns out they produce exactly the same results (when
the lines are coplanar), but their method allows me to eliminate one dot
product (4->3). Not only that, but it turns out that their method works
equally well for skew lines (ie, non-coplanar).

mine:
  CxA.CxA
  -------
  CxA.AxB

theirs:

Bill Currie
8c840a7003 Sanitize trace_hits_plane(). 
While unit normals aren't needed, they were too big for sane math. Now
epsilon can be used for the distance tests. One of the two new tests passes
now :).
 2011-12-06 22:06:25 +09:00

8fe703d747 Trace to adjoining leafs when necessary. 
When the trace stradles a plane in the current leaf, check the other side
of the portal, too, as it is possible that leaf will restrict the movement
of the trace.

All current tests pass! However, I can think of some situations (and I
already have a solution) where things will fail, but that's next.
 2011-12-06 17:27:05 +09:00

Bill Currie
9a9079a2b3 Correct the start-solid in a corner test. 
It turns out that the box trace CAN get out of the solid from that location
(though a similar point trace can not). This is because of my decision to
allow non-points to touch a plane from either side without crossing the
plane, whereas a point touching a plane is always considered to be on the
front side of the plane as there is no further information to disambiguate
on which side of the plane the point is.
 2011-12-05 22:11:58 +09:00
Bill Currie
4419d4c4ad Move the trace into the leaf before testing the contents. 
The trace is moved as far into the leaf as possible without leaving the
other side of the leaf. This ensures that trace_contents is started from a
good location. There is currently a problem with traces that stradle a
plane getting, but this has cleared up all the current contents related
tests.

7da6df9dfb Use the "real" contents of the trace's location when visiting a leaf. 
When visiting a leaf in box mode, use trace_contents() to get the highest
priority contents of any leafs touched by the box in the current location.
I'm now down to one failing test case, and it's an "allsolid" issue that
might be an incorrect assumption in my test case.

f9d56f2941 Add MOD_HullContents(). 
If trace is null or point type, or the hull doesn't have portals, or the
first node is a leaf, MOD_HullContents operates in point mode (exactly the
same way as SV_HullPointContents()). However, in box mode, all leafs
touched by the trace are checked for their contents. The contents field of
trace (a bit field) will indicate the contents type of all touched leafs.
The returned contents value indicates the most important contents:

    solid > lava > slime > water > empty

The one's complement value of the contents type is the bit number of the
contents bit field. I'm not sure how useful this will be as getting the
amount of overlap is currently not supported.

7ee31dd475 Allow the trace start to be in multiple leafs. 
This fixes a couple of in-solid tests, but something better is needed.
 2011-11-28 20:56:21 +09:00
Bill Currie
13d37f4838 Add a bunch of in-solid tests. 
Tests where the box is only partially in a solid tend to fail (particularly
when the solid is on the back side of the split plane).
 2011-11-28 20:56:21 +09:00
Bill Currie
50b08c98fa Add some snug-fit tests and fix the uncovered bugs. 
The tests involve the box fitting into a hole with zero slop (this would be
impossible with point clipping).
 2011-11-28 20:56:21 +09:00
Bill Currie
985667ecba Fix plane touching box backsideness. 
Because a box has size, even when touching a plane, the side on which the
box is can be determined (unlike a point).

Now they represent the lengths of the edges as expected by the edge/polygon
code.
 2011-11-28 20:56:20 +09:00
Bill Currie
60dbc0e342 Fix the last few bugs breaking the distance code. 
The code itself seems to work now. There are still some problems: the box
faces are using unit vectors for the edges, or I should go back to unit
vectors for the portal edges; starting in a solid corner won't always work;
etc. However, that's just mopping up: the main algorithm seems to be
working.
 2011-11-28 20:56:20 +09:00

ab2ec644d6 Clip the portals when running the test cases. 
When the portals are too big, floats break down and break the tests. This
might not be much of an issue in real maps, but my tests use "infinite"
planes.

2abff68089 Fix some more silly bugs. 
The target test now works, but some others have broken due to getting
negative fractions.

Uninitialized variables and crossed signs. Oops :/
 2011-11-28 20:56:20 +09:00
Bill Currie
8fc99566ab Add code to clip the motion of the box to the leaf's portals. 
Unfortunately, something is broken (all box tests fail due to 0 fraction).

Bill Currie
5ee552ea5b Don't normalize the portal edge vectors. 
This simplifies the collision handling code.
 2011-11-28 20:56:20 +09:00
Bill Currie
174f381125 Add some more tests for the ramp. 
These tests pass, but show the basic polygon testing working (just not the
collision handling and thus fraction determination).
 2011-11-28 20:56:20 +09:00
Bill Currie
750b5ba0ed Be a little more lenient with float comparisons. 
Unfortunately, Pythagorus and binary don't play well together, so rounding
errors are inevetible when testing with a slope. However, 1e-6 seems to be
a good epsilon (printf's %g hides it nicely :).

This seems to work better (all previously working tests pass again), but
the target test is still broken.

cde0bbb807 For now, don't use box clipping for point traces. 
Until I figure out how I want to handle zero sized boxes, don't test them.
 2011-11-28 20:54:35 +09:00
Bill Currie
fd5aee1d5e Use the portals to check leaf validity. 
If the trace hits a portal on the plane that brought us to the leaf, then
we actually are in the leaf (otherwise, we shouldn't be here and thus
should ignore the leaf). At least, that's my thinking.

Many point tests fail (but they're really using box clipping with a zero
sized box) and two box tests fail.

91e65b6c80 Rename mplane_t to plane_t and clean up the mess. 
I got rather tired of there being multiple definitions of mostly compatible
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.
 2011-11-28 20:54:34 +09:00
Bill Currie
2f23cfa4d0 Add a new (failing) test case. 
This one demonstrates the need for more information in the bsp tree
(surface polygons). When the box collides with a corner where one side is
flat and the other angled, but there's a partition plane cutting the two,
the box can instead collide with the angled side before it hits the corner.

a943cdf2c4 Handle dual collisions. 
When the trace collides with something on both sides of a plane, the nearer
collision is required. The code now correctly checks both sides and keeps
the nearer collision.
 2011-11-28 20:54:34 +09:00
Bill Currie
0cf5dec5bb Fix the covered step tests. 
However,  there is still a problem with moves where the box is always cut
by the plane: both sides need to be tested (done), but when the first side
checked allows longer motion than the second, but still collides, only the
first side is checked. The shorter motion is required.
 2011-11-28 20:54:34 +09:00
Bill Currie
8cc320b7ef Move the start point to the near side of the crossed plane. 
I'm not sure the end point needs to be moved at all, but I'll leave it
alone for now. I have a couple of failing test cases that seem to be caused
by not handling moves where the box is always cut by the plane.
 2011-11-28 20:54:34 +09:00
Bill Currie
fa6390a46a Correct the sign for the shift in frac. 
However, this is not entirely correct as the new start point when testing
the other side of the plane also needs to be calculated.

9984a2e87a Fix some missing usages of offset. 
This fixes my one failing box clip test. Now I need to find more broken

a356ce6572 Assume the trace will be allsolid. 
Rather than setting allsolid when the trace fails to leave solid space,
clear it when the trace enters non-solid space. This is necessary because
the trace might visit only one node and thus the failure to leave solid
space will not be detected. This fixes the problem with hipnotic's bobbing
water.

This version is broken (it's the one "fixed" by commit 981622f9), but it

 2011-09-27 13:00:19 +09:00
Bill Currie
9daa0b7bde Rename the empty and solid flags, and use them correctly. 
seen_empty and seen_solid much better reflect their meanings, and also use
them correctly (eg, visiting an empty node does not clear seen_solid).
Hipnotic's bobbing water is still broken, though.

981622f969 Make MOD_TraceLine behave "correctly". 
MOD_TraceLine now behaves the same as id's SV_RecursiveHullCheck (from
WinQuake). This means that even if the trace would escape from solid space
into non-solid space, the trace is treated as allsolid if it crosses from
one solid space to another before hitting the empty space.

trace-id.c is used only for establishing the behaviour of id's code.

c2af7896bd Revert "make droptofloor continue the trace if it starts solid" 
This reverts commit 10232acdfe.

figure out just what the trace could really should be doing.
