bbca22c722 [vulkan] Add support for IQM models
Despite the base IQM specification not supporting blend-shapes, I think
IQM will become the basis for QF's generic model representation (at
least for the more advanced renderers). After my experience with .mu
models (KSP) and unity mesh objects (both normal and skinned), and
reviewing the IQM spec, it looks like with the addition of support for
blend-shapes, IQM is actually pretty good.

This is just the preliminary work to get standard IQM models loading in
vulkan (seems to work, along with unloading), and they very basics into
the renderer (most likely not working: not tested yet). The rest of the
renderer seems to be unaffected, though, which is good.

a4f500da3c [vulkan] Add a mini resource subsystem
The resource subsystem creates buffers, images, buffer views and image
views in a single batch operation, using a single memory object to back
all the buffers and images. I had been doing this by hand for a while,
but got tired of jumping through all those vulkan hoops. While it's
still a little tedious to set up the arrays for QFV_CreateResource (and
they need to be kept around for QFV_DestroyResource), it really eases
calculation of memory object size and sub-resource offsets. And
destroying all the objects is just one call to QFV_DestroyResource.

419d91edc5 [image] Set texture type for no-load tga images
I might need to do similar for other formats, but i ran into the problem
of the texture type being tex_palette instead of the expected tex_rgba
when pre-(no-)loading a tga image resulting in Vulkan not liking my
attempt at generating mipmaps.

ef6e4722d5 [simd] Add some comments to mat4fquat
Having to refigure out what values are going into the vectors got old
very fast. The comments don't help with verifying the values, but at
least I can tell at a glance where 2(xy - wz) goes and thus determine
the "orientation" of the matrix.

6d62e91ce7 [gamecode] Clean up progs data access

f6baa16084 [cvar] Remove the cvar lists
They're really redundant, and removing the next pointer makes for a
slightly smaller cvar struct. Cvar_Select was added to allow finding
lists of matching cvars.

The tab-completion and config saving code was reworked to use the hash
table DO functions. Comments removed since the code was completely
rewritten, but still many thanks to EvilTypeGuy and Fett.

bafe54b010 [view] Add a cexpr enum for grav_t

9f876390f0 [input] Fix up some mistranslated cvars
My script didn't know what type to make the cvars since they're not used

floats.

12c84046f3 [cvar] Make cvars properly typed
This is an extremely extensive patch as it hits every cvar, and every
usage of the cvars. Cvars no longer store the value they control,
instead, they use a cexpr value object to reference the value and
specify the value's type (currently, a null type is used for strings).
Non-string cvars are passed through cexpr, allowing expressions in the
cvars' settings. Also, cvars have returned to an enhanced version of the
original (id quake) registration scheme.

As a minor benefit, relevant code having direct access to the
cvar-controlled variables is probably a slight optimization as it
removed a pointer dereference, and the variables can be located for data
locality.

The static cvar descriptors are made private as an additional safety
layer, though there's nothing stopping external modification via
Cvar_FindVar (which is needed for adding listeners).

While not used yet (partly due to working out the design), cvars can
have a validation function.

Registering a cvar allows a primary listener (and its data) to be
specified: it will always be called first when the cvar is modified. The
combination of proper listeners and direct access to the controlled
variable greatly simplifies the more complex cvar interactions as much
less null checking is required, and there's no need for one cvar's
callback to call another's.

nq-x11 is known to work at least well enough for the demos. More testing
will come.

d68db74049 [cexpr] Add a flags type

392e032ce2 [cexpr] Add a get_string function to exprtype_t

supported directly).

e40f3f4f93 [model] Make alias skin loading a batch operation
Really, this won't make all that much difference because alias models
with more than one skin are quite rare, and those with animated skin
groups are even rarer. However, for those models that do have more than
one skin, it will allow for reduced allocation overheads, and when
supported (glsl, vulkan, maybe gl), loading all the skins into an array
texture (since all skins are the same size, though external skins may
vary), but that's not implemented yet, this just wraps the old one skin
at a time code.

9892e571ce [vulkan] Move viewport and scissor into qfv_renderpass_t
This makes much more sense as they are intimately tied to the frame
buffer on which a render pass is working. Now, just the window width
and height are stored in vulkan_ctx_t. As a side benefit,
QFV_CreateSwapchain no long references viddef (now just palette and
conview in vulkan_draw.c to go).

11e30583cf [vulkan] Switch to full screen triangle instead of quad
While I have trouble imagining it making that much performance
difference going from 4 verts to 3 for a whopping 2 polygons, or even
from 2 triangles to 1 for each poly, using only indices for the vertices
does remove a lot of code, and better yet, some memory and buffer
allocations... always a good thing.

That said, I guess freeing up a GPU thread for something else could make
a difference.

6bbbe4997b [vulkan] Invalidate mapped capture image memory
I think I had gotten lucky with captures not being corrupt due to them
being much bigger than all but the L3 cache (and then they're over 1/2
the size), so the memory was being automatically invalidated by other
activity. Don't want to trust such luck, though.

790f62a209 [image] Make WritePNG take settings from tex_t

a29836cc2c [quakefs] Return QFile pointer from QFS_NextFile(name)
QFS_NextFilename was renamed to QFS_NextFile to reflect the fact it now
returns a QFile pointer for the newly created file (as well as the
name). This necessitated updating WritePNG to take a file pointer
instead of a file name, with the advantage that WritePNGqfs is no longer
necessary and callers have much more control over the creation of the
file.

This makes QFS_NextFile much more secure against file system race
conditions and attacks (at least in theory). If nothing else, it will
make it more robust in a multi-threaded environment.

a35bfef24c [sys] Add a function to safely create a unique file
QF currently uses unique file names for screenshots and server-side

QFS_NextFilename has been filling this role, but it is highly insecure
in its current implementation. This is the first step to taking care of
that.

020ada9fb1 [util] Clean up nested macro temp var names a little

495dd759f0 [renderer] Clean up FOV and viewport handling
Viewport and FOV updates are now separate so updating one doesn't cause
recalculations of the other. Also, perspective setup is now done
directly from the tangents of the half angles for fov_x and fov_y making
the renderers independent of fov/aspect mode. I imagine things are a bit
of a mess with view size changes, and especially screen size changes
(not supported yet anyway), and vulkan winds up updating its projection
matrices every frame, but everything that's expected to work does
(vulkan errors out for fisheye or warp due to frame buffer creation not
being supported yet).

3103f400fd [sw] Clean up r_refdef and R_ViewChanged
r_refdef is really meant for holding the various screen "constants" for
the software renderer rather than the more generic scene stuff. All the
fields referenced by the low level rendering code (especially assembly)
have been moved to the beginning of the struct (and nicely fit within 64
bytes). The other fields should be moved elsewhere, but not this commit.

On top of that, R_ViewChanged is much easier to read, and there are
fewer static globals.

a0adca011f [gl] Get fisheye working with frame buffers
Of course, it's not as correct as glsl or sw due to using polygons and

since GL 3.0 is requested, but I don't feel like getting shaders going
just for a couple of post-processing effects in an obsolete renderer).

f2bc5b560f [renderer] Clean up post processing

286344c7b6 [glsl] Implement fisheye rendering
The code dealing with state is a bit of a mess, but everything is
working nicely. Get around 400fps when all 6 faces need to be rendered
(no surprise: it should be about 1/6 of that for normal rendering). The
messy state handling code did not come as a surprise as I suspected
there were various mistakes in my scene rendering "recipe", and fisheye
highlighted them nicely (I'm sure getting this stuff working in Vulkan
will highlight even more issues).

18aae8205e [glsl] Implement screen warp when in liquids

20a2e7e06f [renderer] Get sw fisheye working again
Again, gl/vulkan not working yet (on the assumption that sw would be
trickier).

Fisheye overrides water warp because updating the projection map every
frame is far too expensive.

I've added a post-process pass to the interface in order to hide the
implementation details, but I'm not sure I'm happy about how the
multi-pass rendering for cube maps is handled (or having the frame
buffers as exposed as they are), but mainly because Vulkan will make
implementation interesting.

0c437492b4 [renderer] Move to using dynamic frame buffers
For now, OpenGL and Vulkan renderers are broken as I focused on getting
the software renderer working (which was quite tricky to get right).

This fixes a couple of issues: the segfault when warping the screen (due
to the scene rendering move invalidating the warp buffer), and warp
always having 320x200 resolution. There's still the problem of the
effect being too subtle at high resolution, but that's just a matter of
updating the tables and tweaking the code in D_WarpScreen.

Another issue is the Draw functions should probably write directly to
the main frame buffer or even one passed in as a parameter. This would
remove the need for binding the main buffer at the beginning and end of
the frame.

ee51d06aa3 [renderer] Clean up a lot of recalc_refdef use

5a57280aa9 [gl] Use glGenTextures to allocate texture numbers
While the scheme of using our own allocated did work just fine, fisheye
rendering uses glGenTextures which caused a texture id clash and thus
invalid operations (the cube map texture happened to be the same as the
console background texture). Sure, I could have just "fixed" the fisheye
init code, but this brings gl closer in line with glsl (which makes
extensive use of glGenTextures and glDeleteTextures). This doesn't fix
any texture leaks gl has (plenty, I imagine), but it's a step in the
right direction.

bce7d5b832 [renderer] Clean up use of vup/vright/vpn
This moves the common camera setup code out of the individual drivers,
and completely removes vup/vright/vpn from the non-software renderers.
This has highlighted the craziness around AngleVectors with it putting
+X forward, -Y right and +Z up. The main issue with this is it requires
a 90 degree pre-rotation about the Z axis to get the camera pointing in
the right direction, and that's for the native sw renderer (vulkan needs
a 90 degree pre-rotation about X, and gl and glsl need to invert an
axis, too), though at least it's just a matrix swizzle and vector
negation. However, it does mean the camera matrices can't be used
directly.

Also rename vpn to vfwd (still abbreviated, but fwd is much clearer in
meaning (to me, at least) than pn (plane normal, I guess, but which
way?)).

af0c66dff9 [renderer] Move frame rendering out a layer.
This is a step towards high-level unification of the renderers, as far

to be per-renderer as some things are just not feasible to implement in
all renderers). However, the idea is to move the high-level

ea2fd32228 [renderer] Merge screenshot code as much as possible
Only CaptureBGR is per-renderer as the rest of the screenshot code uses
it to do the actual capture (which is target dependent). Vulkan is
currently broken due to capture being an asynchronous process and the
rest of the code expecting capture to be synchronous (also, bgr vs rgb).

The best thing is all renderers now write the same format (currently
png).

d69355f521 [renderer] Support multiple entity queues
While there's currently only the one still, this will allow the entities
to be multiply queued for multi-pass rendering (eg, shadows). As the
avoidance of putting an entity in the same queue more than once relies
on the entity id, all entities now come from the scene (which is stored
in cl_world in the client code for nq and qw), thus the extensive
changes in the clients.

6ec8e29429 [scene] Track hierarchies instead of root transforms
The root transform of each hierarchy can be extracted from the first
transform of the list in the hierarchy, so no information is lost. The
main reason for the change is I discovered (obvious in hindsight) that
deleting root transforms was O(n) due to keeping them in an array, thus
the use of a linked list (I don't expect a hierarchy to be in more than
one such list), and I didn't want the transforms to be in a linked list.

ae6970a005 [renderer] Split entity queue into per-model-type
While I doubt the difference is all that significant, this should speed
up entity rendering because it cuts out a lot of branching, and
eliminates scanning the same list multiple times only to not do anything
for large chunks of the list.

2477a44d15 [client] Move cshift info from viddef to viewstate
It makes much more sense for cshift state to be in viewstate because it

cd26073b6a [vulkan] Update the sky matrix
Regardless of whether the sky is spinning or not, the matrix needs to be
updated with the current origin in order to get the direction vector
right in the shader. Also, it's in the update that the required x-y
plane rotation gets in so the skies move in the correct direction.

ba3879c6e0 [scene] Make transforms owned by the scene
This actually has at least two benefits: the transform id is managed by
the scene and thus does not need separate management by the Ruamoko
wrapper functions, and better memory handling of the transform objects.
Another benefit that isn't realized yet is that this is a step towards
breaking the renderers free of quake and quakeworld: although the
clients don't actually use the scene yet, it will be a good place to
store the rendering information (functions to run, etc).

4d491a444d [gamecode] Fix handling of undefined builtins
The setup of the function descriptor for undefined builtins was

db8cf68ef3 [gamecode] Pass registered data pointer to builtins
This is the bulk of the work for recording the resource pointer with
with builtin data. I don't know how much of a difference it makes for
most things, but it's probably pretty big for qwaq-curses due to the
very high number of calls to the curses builtins.

Closes #26

7c6ef06dfb [gamecode] Make PF_VarString v6p-only
It's not enforced a this stage, and it would be easy enough to handle,
but it turns out all the standard quake and quakeworld progs never used
... for the print functions: the behavior of PF_VarString was
undocumented and so... tough :P.

208cba85eb [gamecode] Move return buffer to end of progs memory map
With the return buffer in progs_t, it could not be addressed by the
progs on 64-bit machines (this was intentional, actually), but in order
to get obj_msg_sendv working properly, I needed a way to "bounce" the
return address of a calling function to the called function. The
cleanest solution I could think of was to add a mode to the with
instruction allowing the return pointer to be loaded into a register and
then calling the function with a 0 offset for the return value but using
the relevant register (next few commits). Testing promptly segfaulted
due to the 64-bit offset not fitting into a 32-bit value.

The plan is to use the types to extract the number of parameters for a

so).

6514e09e7c [gamecode] Use an explicit size for the null page
It's currently only 4 (or even 3 for v6) words, but this fixes false
positives when checking for null pointers in Ruamoko progs due to
pr_return pointing to the return buffer and thus outside the progs
memory map resulting in an impossible to exceed value.

e1a0c31e3f [qfcc] Encode the new vector types
Thanks to the size of the type encoding being explicit in the encoding,
anything that tries to read the encodings without expecting the width
will simply skip over the width, as it is placed after the ev type in
the encoding.

Any code that needs to read both the old encodings and the new can check
the size of the basic encodings to see if the width field is present.
