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.

4b38048a5c Create functions for rotation and translation. 2012-05-15 21:08:46 +09:00
Bill Currie
5b4fdd2a93 Use the correct position for light calcs. 
I should have remembered that gl_FragCoord wasn't right.

2080c337d7 Avoid using malloc/free every model/frame. 2012-05-15 21:08:46 +09:00

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
Bill Currie
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.
 2012-05-15 21:08:46 +09:00
Bill Currie
74cb49ef7c Free the blended frame data. 2012-05-15 21:08:45 +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).

bea8f8f9c4 Fix a segfault when searching for dlights. 
Uninitialized var bites my bum :P
 2012-05-15 21:08:45 +09:00

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
9c69404163 Attempt to render iqm models. 
Things are a right mess (segfaults, invalid accesses on load, etc), but
hey, it's a start :)

15fd3be73a Allow iqm models when storing efrags. 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
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.
 2012-05-15 21:08:45 +09:00
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.
 2012-05-15 21:08:45 +09:00
Bill Currie
15d35fbdc9 Add mvp_mat and some comments. 2012-05-15 21:08:45 +09:00
Bill Currie
59c5bf2f9e Code up an initial version of the iqm vertex shader. 
Probably more bugs than an old kitchen cupboard :P
 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
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
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
Bill Currie
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).
 2012-05-15 21:08:44 +09:00
Bill Currie
82abd5e426 More matrix tests. 2012-05-15 21:08:44 +09:00

Bill Currie
52ab4f64f9 Add code for loading vertex colors. 
And correct an oopsie in bledweights.
 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
8aabb704d2 Add tests for inverting a dual quad transform. 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

26a878da48 Stub out the iqm loader. 2012-05-15 21:08:43 +09:00
Bill Currie
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.
 2012-05-10 14:48:43 +09:00
Bill Currie
0036a5e113 Ensure edict_size is never 0. 
Avoids division by / in NUM_FOR_EDICT
 2012-05-06 21:35:42 +09:00
Bill Currie
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.
 2012-05-05 18:01:00 +09:00
Bill Currie
cf5c9f067f Make GL_DrawAliasShadow const correct. 
Despair's having troubles with segfaults that I can't reproduce. If it's a
strict aliasing problem, this might help.
 2012-05-05 17:55:30 +09:00
Bill Currie
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
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
0a22a98b60 Fix some mis-versioned opcodes. 
Many of the quaternion opcodes were marked as being available for id progs.
oops
 2012-04-26 10:26:43 +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*).
 2012-04-26 09:48:08 +09:00

7b0d48313d Fix a signed type mixup. 
I mis-applied calim's patch, and gcc failed to tell me :(
 2012-04-26 07:28:22 +09:00
Bill Currie
20b7a46100 Remove a bogus model type check. 
This allows 16-bit alias models to render when viewd straight on.
 2012-04-25 11:50:20 +09:00
Bill Currie
ba7046ea09 Allow large skins in sw32. 
Dirty rotten magic numbers :P
 2012-04-25 10:47:44 +09:00
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
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.

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

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.
 2012-04-21 20:59:04 +09:00
Bill Currie
3b07928373 Fix an inconsistent numeric constant. 
While checking the shaders to see if there might be anything obvious to
work around the current nouveau shader issues, I found a 1 that should have
been a 1.0. I'm surprised it ever compiled.

561484842c Fix some snafus in PL_ParseData

Bill Currie
61ae793367 Fix two broken symbols for sw32. 
Now all 4 render plugins load as standard plugins (though there's still a
problem with libQFrenderer.so)
 2012-04-12 17:12:24 +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

ab486dcdf6 Unregister the quit command before registering it. 
This fixes the quit menu not working.

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.
 2012-04-12 14:40:02 +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
6ff658afe4 Use r_funcs in the client console plugin. 
Getting the sw renderer's functions when running gl was nasty.
 2012-04-11 16:38:15 +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
799a0ae018 Fix a bogus cshift calculation in sw32. 
Found via valgrind and gammatable having become malloced instead of static.
 2012-04-11 14:58:55 +09:00
Bill Currie
07ab5600c9 Recache viddef in *D_InitCaches. 
sw32 now at least doesn't seg, but doesn't draw any 3d. sw renderer seems
to work.
 2012-04-11 14:58:55 +09:00
Bill Currie
42868d308e Initialize the skins and particles subsystems. 2012-04-11 14:58:55 +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.

f5d6959f4b Copy out the model functions pointer. 2012-04-11 14:58:55 +09:00
Bill Currie
6f7b4276e9 Move VID_InitBuffers back from the renderer to targets. 
First, it was nearly identical between sw and sw32 (one paranoia line in
sw32), and second, it's common enough.
 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
772af29cb3 Move the gl cvars into gl. 
That gets rid of the gl_overbrite_f clash. They were put in r_cvar for
saving to the config file, but that was before seta existed.
 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

eb536dc995 Remove D_BeginDirectRect and D_EndDirectRect from gl/glsl. 
They were never really needed anyway (they're for the sw renderer).

80f5cc59e9 Plug a memory leak. 
Allocating (and not freeing) rects every frame... ouch.
 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.

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.

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.
 2012-03-14 16:08:48 +09:00

82679066cc Run a vacuum cleaner over the diffs between x11 and glx init. 
X11 and GLX init are nowhere near as scary as I thought they were, once
they've been tidied up.

72fb96245f Cleanup global symbols for the sw and sw32 renderers. 
Names not mangled, but those symbols that could be made static have been.
Also, many dead variables have been removed.
 2012-02-18 14:34:14 +09:00
Bill Currie
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

d8a37bc791 Correct the usage of gzFile. 
Thanks to spirit for pointing that QF wasn't compiling with zlib 1.2.6
(archlinux, not yet in debian).

I was using gzFile as "gzFile *gzfile", but gzFile is already a pointer. In
older versions of zlib (including the 1.2.3 that's in debian), gzFile is
declared as a void *, and it seems that gcc is happy with assigning void **
to void *. However, in recent zlib, gzFile is now struct gzFile_s *, which
gcc is most definitely unhappy about assigning to struct gzFile **.

I just hope that either I had misread the type back when I wrote quakeio,
or that nobody is using such an ancient zlib.

Thanks to "Sander van Dijk" <a.h.vandijk@gmail.com>, we now have much
better SDL sound support.

Here's the promised cleaned up version of the "double buffer" approach
patch for "snd_sdl.c". I've taken some more time to re-read and test
it this time, and it seems to behave well. All memory that is used by
both the main thread and the SDL audio thread is prefixed with "shm_",
and locking is used to ensure that only one thread accesses it at the

I realized it's pretty silly using colormap + palette when I can just
combine the two into one and have a 2D palette. This is in preparation for
that.

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

8 if I had put the normal index with the vertex rather than st).

 2012-01-03 18:08:01 +09:00
Bill Currie
1437cbec91 Make the face culling a little more sensible. 
GL Quake was weird, culling front faces. Partly understandable, since
Quake's front order is clockwise and GL's default order is
counter-clockwise. However, since the order can be specified, that should
be done instead. Thus, specify the winding order as clockwise (for quake's
data), set culling for back-face removal, and then mess with the winding
direction in the mirror and fish-eye code.

baab15279f Correct the alias vertex data types. 
Vertex locations need to be unsigned byte rather than byte (GL is funy
with that). s and t need to be at least short, and since the normal index
is embedded in the st vector, it needs to be the same type. With this, my
test tetrahedrons seem to be working.

Since I'm not specifying the api when creating my context, mesa is giving
me GL2. This is fair enough, but in GL2, vertex attribute 0 is the vertex
position. This too, is fair enough. The problem is, mesa is assigning 0 to
my vcolor attribute and thus I can't set it. The work around is simply to
swap the declaration order of vcolor and vertex (this really shouldn't work
eiter, I suspect).

87b78e5533 Move the surface chain links out of the surfaces. 
The links are now in "instance surfaces". For non-instanced models (world,

instance surface per model surface. However, for instanced models (ammo
boxes etc), there will be many, dynamically allocated (not yet
implemented). This commit gets the static instance surfaces working.

Bill Currie
3eb859a88f Move the entity transform setup into the clients. 
This has several benifits:
  o The silly issue with alias model pitches being backwards is kept out
    of the renderer (it's a quakec thing: entites do their pitch
    backwards, but originally, only alias models were rotated. Hipnotic
    did brush entity rotations in the correct direction).
  o Angle to frame vector conversions are done only when the entity's
    angles vector changes, rather than every frame. This avoids a lot of
    unnecessary trig function calls.
  o Once transformed, an entity's frame vectors are always available.
    However, the vectors are left handed rather than right handed (ie,
    forward/left/up instead of forward/right/up): just a matter of
    watching the sign. This avoids even more trig calls (flag models in
    qw).
  o This paves the way for merging brush entity surface rendering with the
    world model surface rendering (the actual goal of this patch).
  o This also paves the way for using quaternions to represent entity
    orientation, as that would be a protocol change.

Bill Currie
51aaee5c3b Put that OpenGL error message to rest. 
The error was quite valid: setting GL_TEXTURE_MAX_ANISOTROPY_EXT to 0 is
incorrect. The problem was caused by the call to glTexParameterf being
before the gl_anisotropy cvar was initialized. Thus, move all of the setup
code in GL_Init_Common() to after all the checks and, more importantly,
after the call to GL_Common_Init_Cvars().

14d8e8669f Rework the legacy bind/unbind commands. 
in_bind_imt is now gone. I guess mercury was right in that it was a poor
design. However, it was (and still is necessary) to support "bind" and
"unbind". Now, instead, they work only with the IMT_MOD table. IMT_MOD sits
below IMT_0 in the imt hierarchy. If the key is not bound in IMT_0+, then
IMT_MOD will be checked. This way, "bind" and "unbind" can never mess with
a user's more sophisticated binding setup.
 2011-12-10 13:56:02 +09:00

 2011-12-10 13:24:32 +09:00
Bill Currie
d9d56760e1 Add cvars to control the keys for menus and console. 
The backquote is not always usable for toggling the console, and the new
bind system doesn't automatically bind a key to both game and console imts
(by design). Thus create a cvar that allows the "always works" console
toggle to be specified in eg $fs_globalcfg. While I'm at it, do one for the
menus, too.

45288a1a7f Fix the ghastly sound quality. 
Due to quake's original sound engine using a push model, the actual place
to which the sound data should be written is not necessarily where the

Thus, the correct output location is indicated by snd_paintedtime rather
than snd_shm->framepos.

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).

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.

already have a solution) where things will fail, but that's next.

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.

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

plane getting, but this has cleared up all the current contents related
tests.

This seems to improve the start/all solid cases a little, and it should
speed things up a little by avoiding unnecessary polygon tests.

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).

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).

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.

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

8fc99566ab Add code to clip the motion of the box to the leaf's portals.

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 :).

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.

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.

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.

 2011-09-27 13:00:19 +09:00

9daa0b7bde Rename the empty and solid flags, and use them correctly. 
seen_empty and seen_solid much better reflect their meanings, and also use

Hipnotic's bobbing water is still broken, though.
