Add GLSL directory to QF and use it for all gsls based code (instead of
GL). defines.h, types.h and funcs.h are derived from gl2.h from khronos.
Text drawing now uses triangles instead of quads.
Also, re-implement VectorCompare and QuatCompare using the new macros.
VectorCompCompare and QuatCompCompare take a parameter specifying the
comparison operator to use. All component-wise comparisons must be true
for the whole comparison to be true.
The links are now in "instance surfaces". For non-instanced models (world,
doors, plats etc (ie, world and its sub-models)), there will be one
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.
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.
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.
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.
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.
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.
Currently only "id", "hipnotic" and "rogue" are supported (anything else is
treated as "id"). Has no effect in quakeworld (good thing too: changing
gamedirs is a little broken).
Same as the rotating entities in NQ. Unfortunately, I have some problems
with certain entities doing really weird things during collisions. I'll
sort that out later.
