Both passage and simple text are supported, but only simple text has
been tested at this stage. However, as passage text was taken directly
from rua_gui.c and formed the basis for simple text rendering, I expect
it's at least close to working.
The same underlying mechanism is used for both simple text strings and
passages, but without the intervening hierarchy of paragraphs etc.
Results in only the one view for a simple text string.
I'm not sure I like fontconfig (docs are...), but it is pretty standard,
and I was able to find some reasonable examples on stackexchange
(https://stackoverflow.com/questions/10542832/how-to-use-fontconfig-to-get-font-list-c-c).
Currently, only the one font is handled, no font sets for fall backs
etc. It's meant for the debug UI I'm working on, so that shouldn't be a
big deal.
It's usually desirable to hide the cursor when playing quake, but when
using the console, or in various other states, being able to see the
cursor can be quite important.
It's currently very simplistic (visible, not visible), but it gets
things started for making QF more usable in a windowed environment (not
having a visible cursor was fine in DOS, or when full screen, but not
when windowed (and not actively playing).
With the use of the full type for encoding type aliases, ptraliasenc's
simple check became invalid (it's purpose is to ensure the encoding
doesn't have "null" in it, not the exact encoding itself, but this is
good enough).
Two variables declared as arrays (same size) of different typedefs to
the same base type have their type encodings both pointing to the same
short alias.
From vkgen:
51d3 ty_array [4={int32_t>i}] 207f 0 4
51d9 ty_array [4=i] 1035 0 4
51df ty_alias {>[4=i]} 16 51d9 51e6
51e6 ty_array [4={uint32_t>i}] 2063 0 4
51ec ty_union {tag VkClearColorValue-} tag VkClearColorValue
4ca0 0 float32
51df 0 int32
51df 0 uint32
uint32 should use 51e6 and int32 should use 513d,
This let me keep clearValue's simple default rgba float interpretation,
but also have full control over access to the float32, int32 and uint32
fields.
This is necessary because fisheye rendering draws the scene up to 6
times per frame, which results in many of the limits being hit
prematurely, but updating r_framecount that often breaks dynamic lights.
Really? More to clean up before (vulkan) bsp rendering is thread-safe?
However, R_MarkLeaves was pretty close: just oldviewleaf and
visframecount, but that's still too much. Also, the reliance on
r_refdef.worldmodel irked me.
While there will be some GPU resources to sort out for multi-pass bsp
processing, I think this is the last piece required before shadow passes
can be implemented.
They were an interesting idea and might be useful in the future, but
they don't work as well as I had hoped for quake's maps due to the
overlapping light volumes causing contention while doing the additive
blends in the frame buffer. The cause was made obvious when testing in
the marcher map: most of its over 400 lights have infinite radius thus
require full screen passes: all those passes fighting for the frame
buffer did very nasty things to performance. However, light splats might be
useful for many small, non-overlapping light volumes, thus the code is
being kept (and I like the cleanups that came with it).
Move things around a bit so I can restore the previous behavior of doing
all lights in a single full screen pass but keep the code improvements
from trying to do splatted lighting.
The old system used just "views", but I had at some time decided that I
might want to support specifying buffers and buffer views, but forgot to
change the name in vkparse.c.
While hash tables are useful for large symbol tables, the bool "enum" is
too small to justify one and even bsearch is too expensive (also,
bsearch requires knowing the number of elements, which is a bit of a
hassle currently).
Samplers have no direct relation to render passes or pipelines, so
should not necessarily be in the same config file. This makes all the
old config files obsolete, and quite a bit of support code in vkparse.c.
This gets screenshots working again. As the implementation is now a
(trivial) state machine, the pause when grabbing a screenshot is
significantly reduced (it can be reduced even further by doing the png
compression in a separate thread).
The new system seems to work quite nicely with brush models, which was
the intent, but it's nice to see. Hopefully, it works well when it comes
to shadows. There's still water warp and screen shots to fix, and
fisheye to get working, as well.
