baed4bb160 [gl] Skip lights that are too far from the surface
Where too far is 1024 units as that is the maximum supported, or the
radius. The change to using unsigned for the distances meant the simple
checks missed the effective max dist going negative, thus leading to a
segfault.

966ef949c5 [vulkan] Move oit blending into compose subpass
I had debated putting the blending in the compose subpass or a separate
pass but went with the separate pass originally, but it turns out that
removing the separate pass gains 1-3% (5-15/545 fps in a timedemo of
demo1).

00cade072c [vulkan] Implement order implement transparency
It's a bit flaky for particles, especially at higher frame rates, but
that's due to supporting only 64 overlapping pixels. A reasonable
solution is probably switching to a priority heap for the "sort" and
upping the limit.

ecd5e1de9f [vulkan] Ensure render passes have at least one subpass
Non-graphics render passes don't normally specify render pass info, but
still want frames and command buffers.

b81a77c3f7 [vulkan] Get particle colors working for id style
This required making the texture set accessible to the vertex shader
(instead of using a dedicated palette set), which I don't particularly
like, but I don't feel like dealing with the texture code's hard-coded
use of the texture set. QF style particles need something mostly for the
smoke puffs as they expect a texture.

76258906f9 [vulkan] Skip use of the physics event
It doesn't want to work on my nvidia (or more recent sid?) and doesn't
seem to be necessary. The problem may be multiple event sets before the
first wait, but investigation can wait for now.

38b56b4ce8 [vulkan] Use correct offsets for new particle descriptors
This is probably the biggest reason I had problems with particles not
updating correctly: the descriptors were generally point pointing to
where the data actually was in the staging buffer.

24c08a8dc4 [vulkan] Wait on physics event before drawing particles
This should be more correct. At least it passes validation on my laptop
(intel/llvm): I had trouble with it on nvidia.

51f3d9b777 [vulkan] Fix particle local and dispatch sizes
This gets particles working in renderdoc, but they're quite broken
stand-alone, which I think means that synchronization is a problem.

30b38d7f3f [vulkan] Implement particle rendering
They sort of kind of maybe try to work, but there's plenty wrong. I

d9b0ee22e6 [vulkan] Get particle compute pipelines running
I don't yet know whether they actually work (not rendering yet), but the
system isn't locking up, and shutdown is clean, so at least resources
are handled correctly.

dd1b15c92f [vulkan] Give staging buffers storage usage
Really, additional usage flags should be a parameter. Needed for
particles as the particle updates are read directly from the staging
buffer.

efc3443c61 [vulkan] Create a water warp output pipeline
Although it works as intended (tested via hacking), it's not hooked up
as the current frame buffer handling in r_screen is not readily
compatible with how vulkan output is handled. This will need some
thought to get working.

22615f25ab [vulkan] Move 2d to the output render pass

3360578875 [vulkan] Rework render pass setup
This splits up render pass creation so that the creation of the various
resources can be tailored to the needs of the actual render pass
sub-system. In addition, it gets window resizing mostly working (just
some problems with incorrect rendering).

7829ec3adb [vkgen] Add support for read-only values
This makes it possible to use the parser to read in certain fields, but
skip over others. The read-only is for cexpr parsing of the read-only

7e16822f21 [vulkan] Recreate image available semaphore
It turns out the semaphore used for vkAcquireNextImageKHR may be left in
a signaled state for VK_ERROR_OUT_OF_DATE_KHR. While it seems to be
possible to clear the semaphore using an empty queue submission,
destroying and recreating the semaphore works well.

Still have problems with the frame buffer after window resize, though.

0fdba75a6e [vulkan] Move swap chain image acquisition to the output module
Swap chain acquisition is part of final output handling. However, as the
correct frame buffers are required for the render passes, the
acquisition needs to be performed during the preoutput render pass.
Window resize is still broken, but this is a big step towards fixing it.

92b36582ca [vulkan] Change curFrame from size_t to uint32_t

87f99f9081 [vulkan] Limit shadow textures to 32
This is the minimum maximum count for sampled images, and with layered
shadow maps (with a minimum of 2048 layers supported), that's really way
more than enough.

edc1326736 [vulkan] Search for BGRA8 instead of RGBA8
I guess nvidia gives a non-srgb format as the first in the list, but my
laptop gives an srgb format first, thus the unexpected difference in
rendering brightness. Hard-coding BGRA isn't any better, but it will do
for now.

7a91c905e0 [vulkan] Fix broken line drawing
Line drawing was broken with the 2d depth pass (which will go away in

d673887bf1 [vulkan] Get two render pass rendering working
Things are a bit of a mess with interdependence between sub-module
initialization and render pass initialization, and window resizing is
broken, but the main render pass rendering to an image that is then
post-processed (currently just blitted) is working. This will make it
possible to implement fisheye and water warp (and other effects, of
course).

2cee2f2ab8 [vulkan] Add a module to handle output
When working, this will handle the output to the swap-chain images and
any final post-processing effects (gamma correction, screen scaling,
etc). However, currently the screen is just black because the image
for getting the main render pass output isn't hooked up yet.

aac4c6ef7a [vulkan] Get multiple frame buffers working
Now each (high level) render pass can have its own frame buffer. The
current goal is to get the final output render pass to just transfer the
composed output to the swap chain image, potentially with scaling (my
laptop might be able to cope).

82d1a6e6cd [vulkan] Do a depth pass for 2d objects
While the HUD and status bar don't cut out a lot of screen (normally),
they might start to make a difference when I get transparency working
properly. The main thing is this is a step towards pulling the 2d
rendering into another render pass so the main deferred pass is
world-only.

2828a4ce0c [vulkan] Use a swizzle view for coverage-alpha

glyphs, making for better batching when I get to that.

Bill Currie
40b319bf42 [vulkan] Support swizzles in resource image views
Using swizzles in an image view allows the same shader to be used with
different image "types" (eg, color vs coverage).

Of course, this needed to abandon QFV_CreateImageView, but that is
likely for the best.

534d5367de [vulkan] Use linear sampling for glyphs
This requires having padding around the glyphs to avoid texel leak, but
as the atlas is created at runtime, it's possible to get the padding in.

Bill Currie
4cbacc1149 [vulkan] Remove the pic texel offsets
It turns out that nearest filtering doesn't need any offsets to avoid
texel leaks so long as the screen isn't also offset. With this, the 2d
rendering looks good at any scale (minus the inherent blockiness).

4ff3ca104d [gl] Make conchars use nearest sampling
Linear sampling in a texture atlas (which is what conchars is) requires

e0b9e118a0 [renderer] Remove the 1/2 pixel shift of the 2d screen
It seemed like a good idea at the time, but it exacerbates pixel leakage

modes).

7e442a9019 [renderer] Correct crosshair sizes
I'm pretty sure they're meant to be 8x8 and not 16x16. Certainly they're

2a8c12426d [sw] Ensure the view model has a visibility component
The rest of the system won't add one automatically (since entity

bffe9413b7 [vulkan] Add support for 9-slice rendering
There's no API yet as I need to look into the handling of qpic_t before
I can get any of this into the other renderers (or even vulkan, for that
matter).

However, the current design for slice rendering is based on glyphs (ie,
using instances and vertex pulling), with 3 strips of 3 quads, 16 verts,
and 26 indices (2 reset). Hacky testing seems to work, but real tests
need the API.

b1d7bad2e3 [renderer] Move call to R_ClearEfrags to SCR_NewScene
Probably more such should be moved, but efrags is on my mind. There's no
need for the call to be spread through all the renderers.

Bill Currie
06f410b0b6 [renderer] Clear the visibility components on scene reset
I don't know why it didn't happen during the demo loop, but going from
the start map to e1m1 caused a segfault due to the efrags for a lava
ball getting double freed (however, I do think it might be because the
ball passed through at least two leafs, while entities in the demos did
not). The double free was because SCR_NewScene (indirectly) freed all
the efrags without removing them from entities, and then the client code
deleting the entities caused the visibility components to get deleted
and thus the efrags freed a second time. Using ECS_RemoveEntities on the
visibility component ensures the entities don't have a visibility
component to remove when they are later deleted.

387f17dc0c [scene] Add a color map component
It's currently used only by the vulkan renderer, as it's the only

a28488d2e1 [vulkan] Move both alias color maps into the one layer
This cuts down on the memory requirements for skins by 25%, and
simplifies the shader a bit more, too. While at it, I made alias skins
nominally compatible with bsp textures: layer 0 is color, 1 is emissive,
and 2 is the color map (emissive was on 3).

668f7f2cd2 [vulkan] Use palette lookups for top/bottom colors
As the RGB curves for many of the color rows are not linearly related,
my idea of scaling the brightest color in the row just didn't work.
Using a masked palette lookup works much better as it allows any curves.
Also, because the palette is uploaded as a grid and the coordinates are
calculated on the CPU, the system is extendable beyond 8-bit palettes.

This isn't quite complete as the top and bottom colors are still in
separate layers but their indices and masks can fit in just one, but
this requires reworking the texture setup (for another commit).

4d7f72948d [vulkan] Correct alias g-buffer push-constants
For whatever reason, I had added an extra 4 bytes to the fragment

2e21ca4b9a [vulkan] Upload palette as a 16x16 image
It turns out my approach to alias skin coloring just doesn't work for

251e47f4d6 [vulkan] Add a function to update texture contents
It works on only one layer and one mip, and assumes the provided texture

053c2c47db [vulkan] Double alias top/bottom color values
The bright end of the color map is actually twice the palette value, but
I didn't understand this when I came up with the shirt/pants color
scheme for vulkan. However, the skin texture can store only 0..1, so the
mapping to 0..2 needs to be done in the shader. It looks like it works
at least better: the gold key at the end of demo1 doesn't look as bleh,
though I do get some weird colors still on ogres etc.

9f6c367fce [console] Resurrect console scaling
Currently only for gl/glsl/vulkan. However, rather than futzing with
con_width and con_height (and trying to guess good values), con_scale

0e64f959e2 [scene] Move visibility management into scene code
Well, sort of: it's still really in the renderer, but now calling

over twenty years ago.

73e62de2fb [client] Clean up sbar's globals access
I had forgotten that the cl structs in nq and qw were different layouts,
which resulted in qw's sbar/hud being quite broken. Rather than messing
with the structs, I decided it would be far better in the long run to
clean up sbar's access to the cl struct and the few other nq/qw specific

everything is in the one place.

a07eccd5c7 [glsl] Fix some GLSL conformance issues
I'm not sure when things broke on my laptop (I thought I got warp and

to GLSL errors that I only just noticed. This fixes water warp (and

817aeb334e [ui] Convert view_t to an ECS entity
Much of the nq/qw HUD system is quite broken, but the basic status bar
seems to be working nicely. As is the console (both client and server).
Possibly the biggest benefit is separating the rendering of HUD elements
from the updating of them, and much less traversing of invisible views
whose only purpose is to control the positioning of the visible views.

The view flow tests are currently disabled until I adapt the flow code
to ECS.

There seems to be a problem with view resizing in that some gravities
don't follow resizing correctly.

0a3c7b5b76 [vulkan] Don't use QFV_CreateImage for resource images
The resource functions assume the requested layers is correct (really,

the issue is in QFV_CreateImage, but I want to move away from it
anyway).

169c282187 [vulkan] "Fix" view model check in rendering loop

This fixes the segfault due to the world entity not actually existing,
without adding a world entity. It takes advantage of the ECS in that the
edge renderer needs only the world matrix, brush model pointer, and the
animation frame number (which is just 0/1 for brush models), thus the
inherent SOA of ECS helps out, though benchmarking is needed to see if
it made any real difference.

With this, all 4 renderers are working again.

2a9fcf4f5f [renderer] Tidy up entity component access
Since entity_t has a pointer to the registry owning the entity, there's
no need to access a global to get at the registry. Also move component
getting closer to where it's used.

f37c31a2dc [vulkan] Set entity render id correctly
It was being set to -1 unconditionally due to forgetting to use id.
However, I decided I didn't like reusing the id var and did some
renaming while I was at it.

8acd5c558b [scene] Make entity_t just an entity id for ECS
This puts the hierarchy (transform) reference, animation, visibility,
renderer, active, and old_origin data in separate components. There are
a few bugs (crashes on grenade explosions in gl/glsl/vulkan, immediately
in sw, reasons known, missing brush models in vulkan).

While quake doesn't really need an ECS, the direction I want to take QF
does, and it does seem to have improved memory bandwidth a little
(uncertain). However, there's a lot more work to go (especially fixing
the above bugs), but this seems to be a good start.

ac8c6b631e [vulkan] Skip ambient lights for shadow maps
Not that anything is actually rendered yet, but the validation layers
don't like the null render pass. Came up now because ctf1 seems to make
the first light an ambient light.

6189142c60 [renderer] Remove rglyph_t struct
It didn't really add anything of value as the glyph bitmap rects and the
bearings were never used together, and the rest of the fields were
entirely redundant. A small step towards using a component system for
text.

0c54b0652b Abandon support for clang
The inconsistencies in clang's handling of casts was bad enough, and its
silliness with certain extensions, but discovering that it doesn't
support raw strings was just too much. Yes, it gives a 3s boost to qfvis
on gmsp3v2.bsp, but it's not worth the hassle.

8868a5facf [renderer] Clean up a weird default case
I don't know why I used the void 0 instead of a break when clang
complained (probably rightly) about the default case hitting the end of
the switch.

2c59a400e4 [vulkan] Ensure memory size is aligned
While the base of a memory object was aligned when calculating the
memory block size, the top end was not, which could result in the memory
block not getting enough bytes allocated to satisfy alignment
requirements (eg, for flushing).

While fixing that, I noticed the offsets of objects were not being
aligned when binding, so that is fixed as well.

Fixes Mr Fixit on my VersaPro.

8120adb455 [renderer] Reduce glyph pixel area padding from 2x to 1.2x
With the improved atlas allocation, 2x is no longer needed and 1.2x
seems to be sufficient. Most importantly, it reduced the texture for
amiri-regular.ttf at 72 pix height from 8x to 4x (the staging buffer
isn't big enough for 8k textures).

4feffd2de5 [vulkan] Support multiple loaded fonts
Currently, only 16 fonts can be loaded (I need to sort out descriptor
set pools), but glyphs are grouped into batches of the same font. While
not quite optimal as it can result in bouncing between descriptor sets a
lot, it's still reasonably efficient.

f477f2b96e [vullkan] Rework Draw implementation
Line rendering now has its own pipeline (removing the texture issue).

Glyph rendering (for fonts) has been reworked to use instanced quad
rendering, with the geometry (position and texture coords) in a static
buffer (uniform texture buffer), and each instance has a glyph index,
color, and 2d base position.

Multiple fonts can be loaded, but aren't used yet: still just the one
(work needs to be done on the queues to support multiple
textures/fonts).

Quads haven't changed much, but buffer creation and destruction has been
cleaned up to use the resource functions.

c9e7810864 [vulkan] Add resource memory offset to qfv_resobj_s
Its value on input is ignored. QFV_CreateResource writes the resource
object's offset relative to the beginning of the shared memory block.
Needed for the Draw overhaul.

c028e15943 [vulkan] Add a couple of staging helper functions
I got tired of writing the same 13 or so lines of code over and over (it
actually put me off experimenting with Vulkan). Thus...

QFV_PacketCopyBuffer does the work of handling barriers and a (full
packet) copy from the staging buffer to a GPU buffer.

QFV_PacketCopyImage does a similar job, but for images. However, it
still needs a lot of work, but it does make getting a basic texture onto
the GPU much less of a hassle.

Both functions should make staging data much less error-prone.

0352af4542 [vulkan] Initialize resource image from tex_t
This moves the qfv_resobj_t image initialization code from the IQM
loader into the resource management code. This will allow me to reuse
the code for setting up glyph data. As a bonus, it cleans up the IQM
code nicely.
