This gets the pipelines loaded (and unloaded on shutdown). Probably the
easy part :P. Still need to sort out the command buffers,
synchronization, and particle generation (and probably a bunch else
that's not coming to mind).
It turned out the bindless approach wouldn't work too well for my design
of the sprite objects, but I don't think that's a big issue at this
stage (and it seems bindless is causing problems for brush/alias
rendering via renderdoc and on my versa pro). However, I have figured
out how to make effective use of descriptor sets (finally :P).
The actual normal still needs checking, but the sprites are currently
unlit so not an issue at this stage.
This adds the shaders and the pipeline specs. I'm not sure that the
deferred rendering side of the render pass is appropriate, but I thought
I'd give it a go, since quake sprites are really cutoff rather than
translucent.
As the sw renderer's implementation was the closest to id's, it was used
as the model (thus a fair bit of cleanup is still needed). This fixes
some incorrect implementations in glsl and gl.
qwaq-curses has its place, but its use for running vkgen was really a
placeholder because I didn't feel like sorting out the different
initialization requirements at the time. qwaq-cmd has the (currently
unnecessary) threading power of qwaq-curses, but doesn't include any UI
stuff and thus doesn't need curses. The work also paves the way for
qwaq-x11 to become a proper engine (though sorting out its init will be
taken care of later).
Fixes#15.
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.
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).
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.
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.
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.
I had originally planned on mixing the stage management with general
texture support code like I did in glsl, but I think that was a mistake
and I did keep looking for scrap.[ch] when I wanted to edit something to
do with the scrap...
It optionally generates mipmaps, and supports the main texture types
(especially for texture packs), including palettes, but is otherwise
rather unsophisticated code. Needs a lot of work, but testing first.
The scrap texture did very good things for the glsl renderer and the
better control over data copying might help it do even better things for
vulkan, especially with lots of little icons.
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).
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.
Shaders can be built as spv files and installed into
$libdir/quakeforge/shaders or as spvc files and compiled into the
engine. Loading supports $builtin/name to access builtin shaders,
$shader/path to access external standard shaders and quake filesystem
access for all other paths.
Nothing is actually done yet other than parsing the built-in property
list to property list items (the actual parser is just a skeleton), but
everything compiles
The property list specifies the base structures for which parser code
will be generated (along with any structures and enums upon which those
structures depend). It also defines option specialized parsers for
better control.
The tables are generated from the enums pulled out of the vulkan headers
using a ruamoko program (thanks to its reflection capabilities). They
will be used for parsing property lists used to create render passes and
pipelines.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
