227071bb9a Don't use Soft Particles for particles at player-weapon
or at least if weaponDepthHack is set.

That somehow broke muzzle flash effects in Dentonmod, see

2e0b093c79 Soft particles: Disable Particle Stage "softeningRadius" keyword
this avoid breaking the game DLL ABI (framework/DeclParticle.h is part
of the SDK), and for now doesn't make a difference, because that keyword
was introduced by TDM and thus is only used in their particle defs.

When we break the game ABI/API anyway (probably for high FPS support),
this commit can just be reverted

724ab1727c Add settings for soft particles in menu, documentation, cleanups
r_skipDepthCapture is now called r_enableDepthCapture, and instead of
being a bool it's now an int with -1 meaning "enable if soft particles
are used"

3c887d5af5 Integrate (working!) soft particle shader, clean up that code a bit
turned out the whole problem with soft particles what that the vertex
shader used vertex.attrib[8] instead of vertex.texcoord (and with
nvidia drivers those are equivalent)

I integrated the shader source into the c++ code so I don't have to
ship glprogs/soft_particles.vfp

a407a6060f hack to draw softened particles without blending

580257b47e Make r_showDepth use currentDepthImage, unless r_skipDepthCapture is 1 2024-07-25 03:24:20 +02:00

5ff59547a4 Make r_showDepth work
before it displayed the float values from the depth buffers as
byte-wise RGBA values, which looked weird and wasn't super helpful..

now it's displayed as luminance float (i.e. one float representing
greyscale), and transformed in the same way the TDM particle shader
transforms the depth values to doom units (and then scaled back to
0..1, with 1 representing 3000 units)

6a3fa8c28a Fix depth buffer texture (for soft particle shader effects)
thanks to
https://community.khronos.org/t/cannot-read-from-depth-buffer-in-fs/76169/8

apparently the default doom3 texture filter was something using mipmaps,
which doesn't work so well for textures without mipmaps..
no idea why those two lines in idImage::CopyDepthbuffer() were commented
out, but they're needed (and also un-commented in TDM, I just missed
that when merging -_-)

794d40a04c Add CVar r_vidRestartAlwaysFull
disables partial vid_restarts, hopefully works around issues like
https://github.com/dhewm/dhewm3/issues/587#issuecomment-2206937752

Note that resizing the window by dragging it does *not* call vid_restart
at all, so if you're having issues that are fixed by a full vid_restart
you should also set `r_windowResizable 0`

b2ba15425c Hopefully fix screenshots on Wayland
- screenshots on native wayland (SDL_VIDEODRIVER=wayland) were black,
  at least on Gnome
  => fixed(?) by reading from the default (back) buffer instead of
     the front buffer
- after taking a screenshot, resizing the window (or switching to
  fullscreen) was broken (window remained black or became invisible
  or partly contained garbage), both with native wayland and xwayland
  => fixed by restoring the glReadBuffer state after reading the pixels

94738f1f16 Add glimpParms_t GLimp_GetCurState() to get current window state
it's queried from SDL so it should be up-to-date.
Using it in GLimp_SetScreenParms(), as it mostly did the same SDL calls
to get the current state for the partial vid_restart

Daniel Gibson
44d19a4175 Implement GLimp_SetScreenParms() for "vid_restart partial"
"vid_restart partial" only changes the window size or its fullscreen
(or windowed) state, without recreating everything.
If that fails (or antialiasing settings have changed), it will fall back
to a full vid_restart (this behavior is different than original
 "vid_restart partial" that probably was implemented in Vanilla Doom3
 but not dhewm3)

This is used for Alt-Enter (which toggles between fullscreen and
windowed state) and when pressing the Apply button in the new Video Menu

ac8eec932b Add r_windowResizable to configure if window is resizable
incl. setting in SettingsMenu

With SDL 2.0.5 and newer this change is applied immediately,
2.0.0 to 2.0.4 need a vid_restart
(with SDL1.2 we don't support it at all)

e8b8f5c02d Always optimize code of some integrated libraries, even in Debug builds
the stb libs, miniz and minizip are now always optimized to speed up
performance, esp. level loading times, in debug builds.

So far the stb libs implementation were dragged into the source file
that uses them, now I created additional source files just for them so
those can be optimized while the engine source files using those libs
can remain unoptimized in debug builds.

7ea3e91474 Added new screenshot formats.
Added the ability to change the screenshot format with a new CVar:
r_screenshotFormat. This has four options: 0 (TGA), 1 (BMP), 2 (PNG),
and 3 (JPG). JPG quality can be selected with a new CVar:
r_screenshotJpgQuality. TGA is the default to preserve original behavior
from DOOM 3.

A new dependency on stb_image_write has been added. It has been
included. No additional configuration with CMake is required.

03fccc6220 R_IssueEntityDefCallback() fix bounds check
in the "Work around false positive GCC -W(maybe-)uninitialized warnings"
commit I changed that code.. but my change made it nonsensical,
of course we must get oldBounds before calling the callback which
changes the bounds, otherwise comparing the "oldbounds" with the
current bounds just compares them with themselves..
