Legacy progs do not have the extended defs data (and usually won't have
anything more complicated than a vector), so use the basic type size for
the def size. Fixes broken edict prints.
Standard quake has just linear, but the modding community added inverse,
inverse-square (raw and offset (1/(r^2+1)), infinite (sun), and
ambient (minlight). Other than the lack of shadows, marcher now looks
really good.
Because LoadImage uses Hunk_TempAlloc, the face images need to be copied
individually. Really, what's neeeded is to be able to load the image
data into a pre-allocated buffer (ideally, the staging buffer for
vulkan, but that's for later).
Mostly, this gets the stage flags in with the barrier, but also adds a
couple more barrier templates. It should make for slightly less verbose
code, and one less opportunity for error (mismatched barrier/stages).
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.
The built up "path" name of the handle resource was not always surviving
the intervening call to cexpr_eval_string (in particular, when other
handles were created in the process of creating a handle). Rather than
simply increase the number of va buffers (where would it end?), just
regenerate the path when adding the new handle. It's probably quick
enough, and the code is not usually not on a critical path.
I was reading about multi-pass rendering on mobile devices
(https://developer.oculus.com/blog/loads-stores-passes-and-advanced-gpu-pipelines/)
and discovered that I had used the wrong flags (but then, I think Graham
Sellers had, too, since used his Vulkan Programming Guide as a
reference). Doesn't seem to make any difference on desktop, but as
there's no loss there, but potential gains on mobile, I'd say it's a
win.
QF now uses its own configuration file (quakeforge.cfg for now) rather
than overwriting config.cfg so that people trying out QF in their normal
quake installs don't trash their config.cfg for other quake clients. If
quakeforge.cfg is present, all other config files are ignored except
that quake.rc is scanned for a startdemos command and that is executed.
And improve the generated code for MSG_ReadShort
I suspect gcc didn't like all the excess pointer dereferences and so
couldn't assume that the bytes were being read sequentially.
And improve the generated code as well (ie, use a code sequence that gcc
recognizes and optimizes to a single 32-bit read and a byte-swap).
nq uses big-endian for its packet headers (arg, though it is consistent
with IP, it's not with the rest of quake).
This fixes the textures (and presumably mesh data) being deleted while
still in use. Oddly, the wait was needed in both brush and alias models
(I expected brush to always come first).
I'm not sure that the mismatch between refdef_t and the assembly defines
was a problem (many fields unused), but the main problem was due to
execute permission on the pages: one chunk of asm was in the data
section, and the patched code was not marked as being executable (due to
such a thing not existing when quake was written).
This is a bit of a hack for now (need to look into maybe using cmem),
but it gets 32-bit windows working for all but the software renderer
(probably just refdef (and maybe viddef) getting out of sync with the
assembly code.
This ensures that fov_y is not calculated until after the render view
size is known and thus doesn't become some crazy angle (that happens to
result in a negative tan). Fixes upside-down-quake :)
vid.aspect is removed (for now) as it was not really the right idea (I
really didn't know what I was doing at the time). Nicely, this *almost*
fixes the fov bug on fresh installs: the view is now properly
upside-down rather than just flipped vertically (ie, it's now rotated
180 degrees).
Not only does it makes sense to centralize the setting of viewport and
scissor, but it's actually necessary in order to fix the upside-down
rendering on windows.
This gets the GL and GLSL renderers working for the -win targets... sort
of: they are upside down and GLSL's bsp surfaces are black (same as
Vulkan). However, with this, all 5 renderers at least limp along for
-win, 4/5 work for -sdl.
It turns out the dd and dib "driver" code is very specific to the
software renderer. This does not fix the segfault on changing video
mode, but I do know where the problem lies: the window is being
destroyed and recreated without recreating the buffers. I suspect a
clean solution to this will allow for window resizing in X as well.
