The Blend macro supports any non-integral type supporting * and +
(float, double, vec4f_t, etc), so it is essentially a scalar VectorBlend
or QuatBlend.
Standard quake has just linear, but the modding community added inverse,
inverse-square (raw and offset (1/(r^2+1)), infinite (sun), and
ambient (minlight). Other than the lack of shadows, marcher now looks
really good.
Mostly, this gets the stage flags in with the barrier, but also adds a
couple more barrier templates. It should make for slightly less verbose
code, and one less opportunity for error (mismatched barrier/stages).
This gets the shaders needed for creating shadow maps, and the changes
to the lighting pipeline for binding the shadow maps, but no generation
or reading is done yet. It feels like parts of various systems are
getting a little big for their britches and I need to do an audit of
various things.
QF now uses its own configuration file (quakeforge.cfg for now) rather
than overwriting config.cfg so that people trying out QF in their normal
quake installs don't trash their config.cfg for other quake clients. If
quakeforge.cfg is present, all other config files are ignored except
that quake.rc is scanned for a startdemos command and that is executed.
And improve the generated code for MSG_ReadShort
I suspect gcc didn't like all the excess pointer dereferences and so
couldn't assume that the bytes were being read sequentially.
And improve the generated code as well (ie, use a code sequence that gcc
recognizes and optimizes to a single 32-bit read and a byte-swap).
nq uses big-endian for its packet headers (arg, though it is consistent
with IP, it's not with the rest of quake).
I'm not sure that the mismatch between refdef_t and the assembly defines
was a problem (many fields unused), but the main problem was due to
execute permission on the pages: one chunk of asm was in the data
section, and the patched code was not marked as being executable (due to
such a thing not existing when quake was written).
vid.aspect is removed (for now) as it was not really the right idea (I
really didn't know what I was doing at the time). Nicely, this *almost*
fixes the fov bug on fresh installs: the view is now properly
upside-down rather than just flipped vertically (ie, it's now rotated
180 degrees).
While the main bulk of the improvement (36s down from 42s for
gmsp3v2.bsp on my i7-6850K) comes from using a high-tide allocator for
the windings (which necessitated using a fixed size), it is ever so
slightly faster than using malloc as the back-end.
This is for the conversion /to/ paletted textures. The conversion is
necessary for csqc support. In the process, the conversion has been sped up
by implementing a color cache for the conversion process. I haven't
measured the difference yet, but Mr Fixit does seem to load much faster for
the sw renderer than it did before the change (many months old memory).
This separate the FOV calculations from other refdef calcs, cleaning up the
renderer proper and making it easier for other parts of the engine (eg,
csqc) to update the fov.
The server edict arrays are now stored outside of progs memory, only the
entity data itself (ie data accessible to progs via ent.fld) is stored in
progs memory. Many of the changes were due to code accessing edicts and
entity fields directly rather than through the provided macros.
Loading is broken for multi-file image sets due to the way images are
loaded (this needs some thought for making it effecient), but the
Blender environment map loading works.
They're unlit (fullbright, but that's nothing new for quake), but
working nicely. As a bonus, sort out the sky pass (forced to due to the
way command buffers are used).
There were actually several problems: translucency wasn't using or
depending on the depth buffer, and the depth buffer wasn't marked as
read-only in the g-buffer pass. Getting that correct seems to have given
bigass1 a 0.5% boost (hard to say, could be the usual noise).
That was... easier than expected. A little more tedious that I would
have liked, but my scripting system isn't perfect (I suspect it's best
suited as the output of a code generator), and the C side could do with
a little more automation.
Other than dealing with shader data alignment issues, that went well :).
Nicely, the implementation gets the explicit scaling out of the shader,
and allows for a directional flag.
