Having set_expand exposed is useful for loading data into a set.
However, it turns out there was a bug in its size calculation in that
when the requested set size was a multiple of SET_BITS (and greater than
the current set size), the new set size one be SET_BITS larger than
requested. There's now some tests for this :)
-999999 seems to be a hold-over from the software renderer passed
through both gl renderers. I guess it didn't matter in the gl renderers
due to various draw hacks, but it made quite a difference in vulkan.
Fixes the view model covering the hud.
Quake just looked wrong without the view model. I can't say I like the
way the depth range is hacked, but it was necessary because the view
model needs to be processed along with the rest of the alias models
(didn't feel like adding more command buffers, which I imagine would be
expensive with the pipeline switching).
The idle scale was 114.591559 time too big (forgot both half angle for the
quaternion and converting from degrees to radians for the idle rotations).
Also, take the intermission view position and rotation direct from the
player entity, not viewstate, as while viewstate.origin is the same,
viewstate.rotation is the player's input, not the rotation set by the
server. Fixes the unlocked view angle.
When setting local rotation/scale/transform, need to cache the rotation and
scale, otherwise they can't be fetched easily later on (position is easy as
it's just the fourth column of the matrix).
The recent changes to key handling broke using escape to get out of the
console (escape would toggle between console and menu). Thus take care
of the menu (escape) part of the coupling FIXME by implementing a
callback for the escape key (and removing key_togglemenu) and sorting
out the escape key handling in console. Seems to work nicely
This sorts out the unwanted use of R_EnqueueEntity, which will help with
removing another global (r_ent_queue), which is necessary for threaded
multi-pass rendering (ie, shadows).
This fixes a bug when loading bsp29 files that resulted in leaf nodes
having bogus bounding boxes if any coordinates were negative (and thus
dynamic lights, and probably all sorts of other things) being broken.
And it took me only 9 years to notice :P
Without shadows, this is quite the cheat, but noclip is a cheat anyway,
so probably not that big a deal. It does, however, make noclip usable
for debugging.
Since vulkan supports 32-bit indexes, there's no need for the
shenanigans the EGL-based glsl renderer had to go through to render bsp
models (maps often had quite a bit more than 65536 vertices), though the
reduced GPU memory requirements of 16-bit indices does have its
advantages.
Any sun (a directional light) is in the outside node, which due to not
having its own PVS data is visible to all nodes, but that's a tad
excessive. However, any leaf node with sky surfaces will potentially see
any suns, and leaf nodes with no sky surfaces will see the sun only if
they can see a leaf that does have sky surfaces. This can be quite
expensive to calculate (already known to be moderately expensive for
just the camera leaf node (singular!) when checking for in-map lights)
Getting close to understanding (again) how it all works. I only just
barely understood when I got vulkan's renderer running, but I really
need to understand for when I modify things for shadows. The main thing
hurdle was tinst, but that was dealt with in the previous commit, and
now it's just sorting out the mess of elechains and elementss.
Its sole purpose was to pass the newly allocated instsurf when chaining
an instance model (ammo box, etc) surface, but using expresion
statements removes the need for such shenanigans, and even makes
msurface_t that little bit smaller (though a separate array would be
much better for cache coherence).
More importantly, the relevant code is actually easier to understand: I
spent way too long working out what tinst was for and why it was never
cleared.
This reduces the overhead needed to manage the memory blocks as the
blocks are guaranteed to be page-aligned. Also, the superblock is now
alllocated from within one of the memory blocks it manages. While this
does slightly reduce the available cachelines within the first block (by
one or two depending on 32 vs 64 bit pointers), it removes the need for
an extra memory allocation (probably via malloc) for the superblock.
The renderer's LineGraph now takes a height parameter, and netgraph now
uses cl_* cvars instead of r_* (which never really made sense),
including it's own height cvar (the render graphs still use
r_graphheight).
Ping ack (A2A_ACK) is always a 1-byte packet, so check that the A2A_ACK
is the only byte in the packet before passing the packet to the server
list code. Fixes the mysterious dropped packet every 256 packets as the
low eight bits of the packet's sequence number equalled A2A_ACK.
The uptime display had not been updated for the offset Sys_DoubleTime,
so add Sys_DoubleTimeBase to make it easy to use Sys_DoubleTime as
uptime.
Line up the layout of the client list was not consistent for drop and
qport.
