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.
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().
It turns out that due to the way we do fullbrights, nothing special needs
to be done to get the fullbright texture blended with the model even when
fog is enabled.
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.
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.
The software renderers force the console size to be the same as the window
size (no scaling), but they weren't telling the console of the resize.
oops. Fixes the crash when running the software renderers with default
sizes.
in_dga -> 0 (until X is fixed)
gl_multitexture -> 1 (why was this 0? not enough support back then?)
cl_usleep -> 1 (seems to be ok)
host_mem_size -> 40 (even 32 isn't enough these days)
rate -> 10000 (we're not in the modem era any more)
cl_mem_size -> 32 (16 is not enough, 32 sounds better than 24)
Move the texture coordinates in 1/4 of a pixel. To avoid unnecessary
calculations, pre-caclulate the character cell texture coordinates and
blast them into the the texture coordinate array.
r_skyname now acts as the default sky to use when no sky name is specified
by other means ("none" is still no sky). 'loadsky foo' will load the
"foo*" sky textures, 'loadsky none' gives the default sky, and 'loadsky
""' causes uses r_skyname.
When R_AddEfrags is used (as is the case in nq), this function is
redundant. Brush models in qw are currently broken (invisible), but that's
just a matter of getting qw to use R_AddEfrags instead of R_NewEntity.
This removal should speed up the software renderers a little bit.
o Check the return value of XF86DGADirectVideo.
o Use input_grabbed instead of in_grab for checking whether to enable dga
mouse and other grabbed actions.
