ae78c81b3a [render] Fail gracefully on unsupported render targets 
Ideally, this won't be the case, but it currently is for Vulkan and SDL.

5f93c115ff [util] Make developer flag names easier to manage 
They're now an enum, and the flag part of the name is all lowercase, but
now the flag definitions and names list will never get out of sync.

c9f1d770e0 Merge master into csqc-improvements 
That was a mess

999dd8248b [vulkan] Implement sky box loading and rendering 
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.

c5c44da727 [vulkan] Implement screenshot 
Finally, I can brag about my progress on irc :)

a0d47de439 [vulkan] Suppress all the debug output 
silence is golden

8f7d6b1d02 [vulkan] Initialize skins 
This allows the qw client to run with Vulkan.

0366b72d4a [vulkan] remove the fps printing 
Now that pixels are rendered, there's no need to print the fps
separately as the in-game display works quite nicely.

10a1b99a92 [vulkan] Implement lighting and compose passes 
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.

9229b67633 [vulkan] Clean up the new render pass and framebuffers 2021-02-24 16:27:56 +09:00
Bill Currie
82eabb5ca2 [vulkan] Parse clear values 
And get the render pass working in general. Note that this is only the
render pass and frame buffers: actual commands still have problems.

a94949c009 [vulkan] Start moving towards a deferred renderer 
After getting lights even vaguely working for alias models, I realized
that it just wasn't going to be feasible to do nice lighting with
forward rendering. This gets the bulk of the work done for deferred
rendering, but still need to sort out the shaders before any real
testing can be done.

c536a363ec [vulkan] Remove namehack.h 
Never really wanted in the first place (back when I did the plugin
renderers), but I didn't feel like doing the required work to avoid it
at the time. At least with Vulkan being a fresh start in an environment
that's already plugin-friendly, there was no real work involved. I'll
get to the other renderers eventually (especially now that I know gdb
does the right thing when there are multiple functions with the same
name).

1275067655 [vulkan] Rename vulkan_framebuffer_t 
It turns out I had conflated frame buffers with frames and wound up
making a minor mess when separating the number of frames the renderer
could have in flight from the number of swap-chain images. This is the
first step towards correcting that mistake.

ebb73e19b2 [vulkan] Use the msaaSamples cvar 
That took a bit of fiddling with the render pass to get things working
for both sampling and no sampling (ie, msaaSamples = 1).

ea72d0c60e [model] Clean up the globals for alias models 2021-02-01 21:11:45 +09:00
Bill Currie
bb6c6963d2 [model] Clean up the globals around model loading 
Covers only the generic load code (alias etc to follow), but this should
take care of a lot of issues in the future.

93e9f89bd3 [vulkan] Create some default textures 
Black, white and magenta. This gets glow (full bright) maps working.

9e03096da6 [vulkan] Build brush model display lists 
Not working particularly well yet, but no errors out of validation.
 2021-01-21 02:13:40 +09:00

9eef805b7d [vulkan] Generate triangle fans for bsp models 
They're not uploaded to the card yet, but the basics seem to be working.
 2021-01-20 15:11:50 +09:00
Bill Currie
d33f5b8d0d [vulkan] Make a lot of progress for brush models 
Light maps are maybe updating, but as nothing is actually rendered yet,
it's hard to tell.
 2021-01-20 01:28:54 +09:00

0f81432090 [model] Load bsp textures into vulkan 
The textures for an entire model are loaded into a single memory object
with shared between multiple images.
 2021-01-20 00:37:37 +09:00
Bill Currie
6e0cb7b917 [model] Isolate renderer specific texture data 
This cleans up texture_t and possibly even improves locality of
reference when running through texture chains (not profiled, and not
actually the goal).
 2021-01-19 13:07:31 +09:00
Bill Currie
40fc9f0000 [model] Make Mod_LoadExternalTextures private 
It never really needed to be externally accessible as it has always been
gl-specific and can be called by Mod_ProcessTexture anyway.

dacda50130 [renderer] Stub out all the vulkan functions 
nq-x11 now gets through all three demos without crashing (but without
rendering anything useful, though).
 2021-01-18 12:46:06 +09:00
Bill Currie
8078e10ea1 [vulkan] Make frame-buffers independent of swapchain 
This is more correct as the environment (X11 etc) might provide more
swapchain images than we want: 3 frames in flight is generally
considered a good balance between saturating the hardware and latency.
 2021-01-16 21:24:42 +09:00

ad9c3193fa [vulkan] Use darray size to control cmd buffer count 
This allows the array in which the command buffers are allocated to be
allocated on the stack using alloca and thus remove the need to
malloc/free of relatively small chunks.

858ac19327 [renderer] Move r_screen and r_cvar into main bin 
r_screen because of SCR_UpdateScreen, and r_cvar because the cvars
really should never have been in a plugin in the first place (and
r_screen needed access).

bb4ca7683e [vulkan] Get the 2D pipeline up and running 
First pixels! This was a nightmare of little issues that the validation
layers couldn't help with: incorrect input assembly, incorrect vertex
attribute specs. Though the layers did help with getting the queues
working. Still, lots of work to go but this is a major breakthrough as
I now have access to visual debugging for textures and the like.

8f6f32981c [vulkan] Add some matrix buffers 
It seems they could all be in the one buffer: there are indications that
uniform binding can be fairly fine-grained. I need to investigate that.
 2021-01-12 11:26:20 +09:00
Bill Currie
6e636a27d0 [renderer] Continue the job of merging SCR_UpdateScreen 
I think this is probably as merged as it will get (though the update
callbacks can probably do with some merging).
 2021-01-11 16:57:31 +09:00
Bill Currie
23db917ec4 [vulkan] Create a staging buffer struct 
And move the barrier prefabs into a more convenient place.
 2021-01-11 01:24:15 +09:00
Bill Currie
ba6450d0b4 [vulkan] Make a start on the 2D pipeline 
Short wrappers for Draw functins are in vid_render_vulkan.c so the
vulkan context can be passed on to the actual functions. The 2D shaders
are set up similar to those in glsl, but with full 32-bit color (rgba)
support instead of paletted. However, the textures are not loaded yet,
nor is anything bound.
 2021-01-10 15:56:17 +09:00
Bill Currie
e7106cce9e [plugin] Remove Draw_Init from draw funcs 
It's never called outside the renderers.
 2021-01-10 15:22:39 +09:00

b6d2c63059 [vulkan] Fix some formtatting 
Both code and developer output.
 2021-01-07 22:49:43 +09:00

25ade4c0f3 [vulkan] Add support for custom parsers 
And provisionally parse shader stage defs.
 2020-12-24 01:36:17 +09:00

0a0035e5e5 Use the render pass to clear the window 
Very satisfying to get to this point.

89d48b5650 Output first pixels 
Just clearing the screen to 0xbada55, but the validation layer is quiet.

94565c2382 Rework much of the Vulkan array handling 
So much for all those little wrappers hiding the device. Some survived,
but mostly just the bigger things like device, swapchain, etc.
 2020-02-17 20:29:35 +09:00
Bill Currie
916e57de37 Get the swapchain image switching sort of working 
The render pass isn't set up yet, so the validation layer is having a
fit, but cycling through the swapchain images does seem to be working.
 2020-02-17 00:50:39 +09:00
Bill Currie
559bd2e636 Create command pool and frame timing fences 
Nothing is actually done yet, so the reported fps is around 172k (yes,
k), but startup and shutdown seems to be clean (yay validation layers).

b3d982bfc3 Remove global vulkan_ctx 
While I can't say that I'm happy with the details of vulkan_ctx_t, I am
pretty sure I don't want to be limited to having only one.

8ee06d75a9 Separate render and presentation initialization 
This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.
 2019-07-09 01:00:47 +09:00

6ee2df8445 Move vid callbacks into vid_internal 
Currently segfaults because viddef is an alias for *r_data->vid, which
has not yet been initialized (chicken and egg).

77afc30486 Fix vid renderer plugin types 
I guess that plugin type is currently not checked, otherwise I doubt the
mistake would have gone unnoticed.

2bc78e7f0a Start work on a Vulkan-based renderer 
Doesn't do much other than create an instance and enumerate some stuff,
but the build system is working.
