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.

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.

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.

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)

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.

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.

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).

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).

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.

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:
  CxA.AxB

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 :).

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.

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.

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.

Bill Currie
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.

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).

Bill Currie
50b08c98fa Add some snug-fit tests and fix the uncovered bugs.

985667ecba Fix plane touching box backsideness.
Because a box has size, even when touching a plane, the side on which the

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.

ab2ec644d6 Clip the portals when running the test cases.
When the portals are too big, floats break down and break the tests. This

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