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.
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.
sane now. Also optimize QSG2 color handling, and fix some QSG2 bugs. Not that
anyone cares, nobody uses it anyways.
Should be faster, but isn't here. *grmbl*
Now just have one (known) issue with bmodels with fullbright textures not
rendering their base texture. Floating fullbrights are nifty!
Also a number of optimizations, which need wider performance testing.
"Fixes a bug in dynamic lights (lightstyles weren't being rendered correctly
due to bad assumptions about dlightbits)"
It compiles fine, and seems to work, so, here it is.
Hikaru
functions when told to. also make gcc warn if it can't inline a function.
Explicitly inline several functions (including moving VectorNormalize to
mathlib.h so it /can/ be) resulting in a 5.5% speedup for spam2 (88 to 92
fps)
Calculate radius for alias models as well as brush.
Culling is no longer optional on alias models (was only ever disabled for viewmodel, which is a lot of extra effort to avoid clip testing 1 thing out of hundreds).
Clip QSG2 scaled alias models with a scaled bbox.
The real problem with greyscale lighting, is in brush model loading. It'll probably take me a while to sort it out, since taniwha didn't get to it before taking off for the weekend. Sorry...
support for BSP models, until they can be fixed. gl_multitexture should now
actually be a speedup!
NOTE: Some OpenGL implementations have trouble with the texture function
used. 3Dfx Voodoo 1/2 are known to have this trouble. I don't know how to fix
this, or even if it can be fixed. :/
Also some small cleanups in particles.
Brighten grenade smoke a tiny bit, so it's not so invisible in the typically dark quake areas.
And some minor cleanups to water rendering.
Speed lightmap calculations up for r_lightmap_components 1.
Enough to give a 4.4% speedup to timedemo overkill.
Hint: int/float/int conversions are expensive.
as the black polygons (duh:) and not as nice looking as the sky dome, but also
not as slow (fps when standing in the normal coridor looking at the sky in
start: 26 for skydome, 37 for id skys, 44 for black). Good for when you want
to see sky other than black but your card can't handle the fillrate
requirements of skydome. I'll clean up the sqrt in there soonish.
R_MarkLights is now about 3% instead of about 15%, I've lost 8 fps on my
null GL speed test. However, R_AddDynamicLights has jumped up a bit, so I'm
wording if maybe more surfaces are being lit.
The major change is that we no longer require libGL to even exist on the
system at compile time for the GL targets, we dynamicly link to the
libGL of choice at run time. (This probably breaks most non-linux
systems, and all GL targets except -glx, some fixup will be needed.)
(This also kills glquake, dead dead DEAD! GONE FOREVER! WHEE!)
Some gl_draw cleanup.
Commented out equake alias model occlusion test stuff, very experimental.
Added the .lo and .la patterns to the .gitignore files.
Some minor sbar cleanup. (We don't use the disc in use symbol for
anything.)
