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
so when the shader writes a debug value as a color,
I get to see that color

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

5c7aacb954 Make fullscreen mode with XWayland a bit less broken, #587
assert( ret.width == glConfig.winWidth
        && ret.height == glConfig.winHeight );

in GLimp_GetCurState() triggered, because SDL_GetWindowSize(),
which was used to set glConfig.winWidth/Height in
GLimp_UpdateWindowSize(), returned different values than
SDL_GetWindowDisplayMode().
Now use SDL_GetWindowDisplayMode() in GLimp_UpdateWindowSize() so it's
at least consistent.

However it seems like SDL_GetWindowSize() returns the correct values
(IN THAT CASE), because with this change the mouse cursor doesn't work
that well (in the specific case described above).
In the end this is an SDL or Wayland bug or something, and I can only
recommend not using "real" fullscreen mode with Wayland, as it's fake
anyway (Wayland doesn't allow switching the display resolution, so
you get a magically scaled borderless fullscreen window at best)

9eff1d9be2 Dhewm3SettingsMenu: Rework resolution/windowed/MSAA part of Video Options
Now the CVars are set immediately and "Apply" only does
`vid_restart partial`, while "Reset" resets the CVars to the values
that were set when opening the menu.
This also works the other way around: Changing a CVar (in the console
or other menu or r_fullscreen with Alt-Enter) is immediately reflected
in the menu.

Furthermore, "fullscreen desktop" now is its own setting (=> can be set
even if windowed mode is selected), to accommodate switchting between
windowed and fullscreen with Alt-Enter

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

c096a86ce8 Fix toggling fullscreen mode with vid_restart partial, esp for Alt-Enter
Toggling with Alt-Enter relies on idRenderSystem::IsFullScreen() which
returns glConfig.isFullscreen

That can only work if GLimp_SetScreenParms() actually sets
glConfig.isFullscreen

Thanks j4reporting for reporting this! :)

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.

ecee402927 Dhewm3SettingsMenu: properly handle playername encoding and length
ImGui uses UTF-8 for strings, Doom3 uses ISO8859-1, so the playername
must be translated.
Also it seems like the playername should have at least 40 chars,
at least that's the limit imposed by the original Doom3 menu

6dc36c6175 Add some functions to handle UTF-8 strings
- convert to/from ISO8859-1 (Doom3's "High ASCII" encoding)
- count Unicode codepoints in UTF-8 string
- cut UTF-8 string off after N codepoints
- use the conversion function to replace iconv in sys/events.cpp

50d7129b1c New input CVars: in_allowAlwaysRunInSP, m_invertLook
in_allowAlwaysRunInSP allows using in_alwaysRun and in_toggleRun
in Single Player (it'll still drain your stamina!)

m_invertLook allows inverting mouse look, both for up/down and
left/right, if you're into that kind of thing

bd22f55f56 Dhewm3SettingsMenu: Support new sound CVars, show OpenAL info 2024-06-01 07:11:14 +02:00
Daniel Gibson
2c58845d28 Several OpenAL improvements
- s_scaleDownAndClamp CVar so the clamping and scaling down of all
  sounds (that is done to prevent clipping) can be disabled
  (enabled by default)
- s_alOutputLimiter CVar to allow configuring ALC_SOFT_output_limiter
  which (if enabled) reduces the overall volume if it gets too loud,
  to avoid clipping (defaults to -1 = "let OpenAL decide")
- s_alHRTF to allow enabling or disabling HRTF, requires ALC_SOFT_HRTF
  (defaults to -1 = "let OpenAL decide")

Those CVars can be changed at runtime and are applied immediately
(in case of s_alHRTF and s_alOutputLimiter by resetting the OpenAL
 device, just like we do when a disconnect is detected)
