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).

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 :).

2b65f81b72 Use a saner "infinity".

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.

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
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.

4e76aa3025 Don't split on a plane parallel to the motion.
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.

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.

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 :).

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.

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

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
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

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.

49a85718f8 total nukage of Con_*Printf calls from libs (except for video). Sys_*Printf
(Sys_DPrintf is new) is now used exclusively for all lib printing. Con_Init
sets the sys printf recirection to Con_Print (which has been revamped
appropriatly) and the server sets it to SV_Print (which was SV_Printf and
the new SV_Printf calls /it/). This should fix the rcon print redirection
issues.

6cab8cf4e0 - change Cache_Get calls to Cache_TryGet (which I just added), so they
can tollerate failure.
- minor error message tweak (an emptry string is not NULL!)
