This is the first step towards component-based entities.
There's still some transform-related stuff in the struct that needs to
be moved, but it's all entirely client related (rather than renderer)
and will probably go into a "client" component. Also, the current
components are directly included structs rather than references as I
didn't want to deal with the object management at this stage.
As part of the process (because transforms use simd) this also starts
the process of moving QF to using simd for vectors and matrices. There's
now a mess of simd and sisd code mixed together, but it works
surprisingly well together.
This is a big step towards a cleaner api. The struct reference in
model_t really should be a pointer, but bsp submodel(?) loading messed
that up, though that's just a matter of taking more care in the loading
code. It seems sensible to make that a separate step.
The setup had been lost at some stage, thus shadows were always directly
under the entity. Unlike the original quake shadow code, the vector is
correctly transformed into the entity's space.
I finally found the cause of Despair's gl shadows non-rendering+segfault...
the shadow code expected triangle fans and strips but was getting simple
triangles. Oops.
Where possible, symbols have been made static, prefixed with gl_/GL_ or
moved into the code shared by all renderers. This will make doing plugins
easier but done now for link testing.
For now, only the glsl loader disables caching, but it stores the frame
vertices in GL memory, so its hunk usage is relatively lower (and will be
lower still when I get skins sorted out).
After getting in contact with serplord, I now know that the sw alias
loading was correct. Turns out the gl loaders was mostly correct, just a
mistaken subtract rather than add. And with that, I can implement alias-16
support in glsl. better yet, since all the work is done in the loader, the
renderer doesn't know anything about it :) However, I need to create some
16-bit models for testing.
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.
My changes:
Emit normals if truform is enabled.
Attempt to avoid 0,0,0 normals (makes lighting & tesselation unhappy).
Fix some (ancient) apparent bugs in GetAliasFrameVerts16().
Clamp minlight, instead of adding it.
Apply colormod as glColor, rather than adding it to emission, to prevent QSG2
issues with fullbrights.
Rearrange init code, and don't go quite as wild with responsiveness to lights.
Material & lightmode settings will need tweaking & testing to work well on all
cards. Feedback needed there.
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.
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)
