Useful for avoiding a pile of wrapper functions that merely pass on
command-specific data to the actual implementation. Used to clean up the
wrappers in nq and qw cl_input.c
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.
The plan is to have a fully component based entity system. This adds
hierarchical transforms. Not particularly useful for quake itself at
this stage, but it will allow for much more flexibility later on,
especially when QuakeForge becomes more general-purpose.
This seems to be pretty close to as fast as it gets (might be able to do
better with some shuffles of the negation constants instead of loading
separate constants).
It's not used yet as work needs to be done to better support generic
entities, but this is the next step to real-time lighting (though, to be
honest, I expect it will be too slow to be usable).
The main purpose is to allow fluent-style:
const char *targetname = PL_String (PL_ObjectForKey (entity, "targetname"));
if (targetname && !PL_ObjectForKey (targets, targetname)) {
PL_D_AddObject (targets, targetname, entity);
}
[note: the above is iffy due to ownership of entity, but the code from
which the above comes works around the issue]
There's still the memory management itself to clean up, but the main
code no longer uses any static/global variables (holdover from when the
function was recursive rather).
The static libs are used to build the plugins, but make it easy to use
only those modules needed for tests. Fixes the link error when running
"make check" with non-static plugins.
Static lights are yet to come (so the screen is black most of the time),
but dynamic lights work very nicely (and look very good) despite the
falloff being incorrect.
While I could reconstruct the position from the screen coords and depth,
this is easier and good enough for now. Reconstruction is an
optimization thing.
Lighting doesn't actually do lights yet, but it's producing pixels.
Translucent seems to be working (2d draw uses it), and compose seems to
be working.
