Forgetting to invoke [super dealloc] in a derived class's -dealloc
method has caused me to waste far too much time chasing down the
resulting memory leaks and crashes. This is actually the main focus of
issue #24, but I want to take care of multiple paths before I consider
the issue to be done.
However, as a bonus, four cases were found :)
This takes care of the global variables to a point (there is still the
global struct shared between the non-vulkan renderers), but it also
takes care of glsl's points-only rendering.
After yesterday's crazy marathon editing all the particles files, and
starting to do another big change to them today, I realized that I
really do need to merge them down. All the actual spawning is now in the
client library (though particle insertion will need to be moved). GLSL
particle rendering is semi-broken in that it now does only points (until
I come up with a way to select between points and quads (probably a
context object, which I need anyway for Vulkan)).
This has the advantage of getting entity_t out of the particle system,
and much easier to read math. Also, it served as a nice test for my
particle physics shaders (implemented the ideas in C). There's a lot of
code that needs merging down: all but the actual drawing can be merged.
There's some weirdness with color ramps, but I'll look into that later.
They should increment by one for each pic, not 4 (I think some fluff
remaining from copying glsl's draw code).
I noticed the problem when I saw large gaps of 0s in the vertex data in
renderdoc.
This means color, emission, and translucent. Fixes the HOM issues on my
VersaPro (but halves the frame-rate... definitely need to bring back the
forward renderer as an option).
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).
This needed changing Vulkan_CreatePipeline to
Vulkan_CreateGraphicsPipeline for consistency (and parsing the
difference from a plist seemed... not worth thinking about).
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.
I'm not at all sure what I was thinking when I designed it, but I
certainly designed it wrong (to the point of being fairly useless). It
turns out memory requirements are already aligned in size (so just
multiplying is fine), and what I really wanted was to get the next
offset aligned to the given requirements.
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.
With the switch to multi-layer textures for brush models, the bsp and
alias texture descriptor sets became identical and thus the definitions
shareable. However, due to complications I don't want to address yet,
they're still separately identified, but I should be able to use the
texture set for most, if not all, pipelines.
I'd forgotten (when doing the original brush texture loader) that
turbulent surfaces were unlit and thus always full-bright, then never
wrote the turb shader to take care of it. The best solution seems to be
to just mix the two colors in the shader as it will allow turb surfaces
to be lit in the future (probably with severely limited light counts due
to being a forward renderer).
This gets the alias pipeline in line with the bsp pipeline, and thus
everything is about as functional as it was before the rework (minus
dealing with large texture sets).
I guess it's not quite bindless as the texture index is a push constant,
but it seems to work well (and I may have fixed some full-bright issues
by accident, though I suspect that's just my imagination, but they do
look good).
This should fix the horrid frame rate dependent behavior of the view
model.
They are also in their own descriptor set so they can be easily shared
between pipelines. This has been verified to work for Draw.
BSP textures are now two-layered with the albedo and emission in the two
layers rather than two separate images. While this does increase memory
usage for the textures themselves (most do not have fullbright pixels),
it cuts down on image and image view handles (and shader resources).
Smashing everything in the process :P (need to work on the C side).
However, while bindless is supposedly good for performance, the biggest
gain this will bring is portability: the texture counts are
automatically limited to what the hardware can handle, and the reliance
on push descriptors is removed (though they were nice and did help get
things up and running).
I had forgotten that the parameters are in reverse order, and even if I
had remembered, I forgot to reset offset before the second loop.
Pre-decrementing offset takes care of both issues at once.
My VersaPro doesn't support more than 32 per-stage samplers (lavapipe).
This is a small part of getting Vulkan to run on lavapipe and even in
itself is rather incomplete.
Fixes the warning about parse_fixed_array not being used (oops, the
problem with partial commits), but more importantly, gives access to
things like maxDescriptorSetSamplers.
This will make property list expressions easier to work with. The
library is rather limited right now (trig, dot, min/max/bound) but even
just min adds a lot of functionality.
I want to support reading VkPhysicalDeviceLimits but it has some arrays.
While I don't need to parse them (VkPhysicalDeviceLimits should be
treated as read-only), I do need to be able to access them in property
list expressions, and vkgen generates the cexpr type descriptors too.
However, I will probably want to parse arrays some time in the future.
This ensures that unused parser blocks do not get emitted. In the
testing of the upcoming support for fixed arrays, the blend color
constants were being double emitted (both as custom and normal parser)
due to being an array. gcc did not like that (what with all those
warning flags).
Multiple render passes are needed for supporting shadow mapping, and
this is a huge step towards breaking the Vulkan render free of Quake,
and hopefully will lead the way for breaking the GL renderers free as
well.
This is actually a better solution to the renderer directly accessing
client code than provided by 7e078c7f9c.
Essentially, V_RenderView should not have been calling R_RenderView, and
CL_UpdateScreen should have been calling V_RenderView directly. The
issue was that the renderers expected the world entity model to be valid
at all times. Now, R_RenderView checks the world entity model's validity
and immediately bails if it is not, and R_ClearState (which is called
whenever the client disconnects and thus no longer has a world to
render) clears the world entity model. Thus R_RenderView can (and is)
now called unconditionally from within the renderer, simplifying
renderer-specific variants.
While using binary data objects for specialization data works for bools
(as they can be 0 or -1), they don't work so well for numeric values due
to having to get the byte order correct and thus are not portable, and
difficult to get right.
Binary data is still supported, but the data can be written as a string
with an array(...) "constructor" expression taking any number of
parameters, with each parameter itself being an expression (though
values are limited at this stage).
Due to the plist format, quotes are required around the expression
("array(...)")
