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().
For some reason, the construct \c " in config.dox makes the custom \QF
command fail to work for the rest of the file, and escaping the quote
doesn't help. Work around for now by using words.
The special token __INFINITY__, like __FILE__ and friends, will expand to
a floating-point expression containing a value the C compiler considers
infinite. Obviously, this assumes that the system has relatively modern
float hardware -- but if it doesn't, having Ruamoko be able to represent
float infinity is the least of your problems. :)
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.
After discussing things with Spike of FTE, it seems that not many clients
handle zero length mvd packets particularly well. While it the skip code
might be useful for qtv, getting the packets into one but not the other
seems to be not worth the effort at this stage.
There are some problems with menus and the console messing up the key_dest
state (they assume console/menu or game, nothing else), but otherwise
things seem to work.
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 the default sound device does not support mmap access, retry with
plughw. However, assume the user knows best and do not retry if snd_device
has been set to anything, including "default".
QF alsa support now works out of the box with pulseaudio.
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
"hardware" dma cursor is, but rather where the last write finished off.
Thus, the correct output location is indicated by snd_paintedtime rather
than snd_shm->framepos.
I've had enough of this for the moment, but I'm pretty sure the test needs
some more consideration, and I'll probably forget about it if I don't mark
it.
