The previous commit didn't fix the issue for the pistol and only was a
workaround anyway. So I reverted that and fixed the issue properly.
The underlying issue is that the particle's material sets the
texture matrix (with "translate" or "scale" or whatever), and the soft
particle rendering code (and shader) didn't take the texture matrix
into account.
Now it does, in a similar way as the interaction shader code.
Fixes https://github.com/dhewm/dhewm3-sdk/issues/36
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
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
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)

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 -_-)
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`
- 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
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
"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
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)
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.
apparently this happens sometimes, but not often enough to reproduce
properly?
also some small changes (mostly formatting) to Configuration.md
refs #540
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.
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..
