Sandy Bridges hardware is OpenGL 3.2 compatible and Mesa3D has a working
driver. But the crappy Windows driver is limit to OpenGL 3.1... GL3 is
working on Linux, but not on Windows.
Highlights are:
- Since MSYS2 is much more unixlike than our old build environment we
can remove most Windows specific hacks from the Makefile.
- MSYS2 has an package manager, the build environment can be updated
by "pacman -Syu" just like an ordenary Arch Linux installation.
- Parallel builds are now working.
- git is integrated into the build envirment.
- zlib is now linked as a dynamic lib.
After this commit the old bild environment will no longer work! The
latest version must be downloaded and extracted to C:\MSYS2. Get it

The model shadows are rendered after all entities are rendered.
This fixes them making entity brushes below them translucent (#194)
The model rendering code used lots of global variables, many of them
totally superfluous (esp. currententity, currentmodel).
I refactored the code to use less global variables (this was at least
partly needed to render the shadows later).
So this looks like lots of changes, but many of them are just using
"entity" instead of "currententity" or "model" instead of "currentmodel"
Like GL1 gl_shadows + gl_stencilshadows: no shadow volumes, but looks
ok apart from standing over edges
The gl_stencilshadows cvar isn't used in GL3, it always uses the stencil
buffer if available (and if gl_shadows != 0)
This still needs performance optimizations: Like the GL1 impl it takes
lots of draw calls per model, it could be done with one per model like
when rendering the actual model.
there have been complaints that those things look too bright, so let
people configure their intensity independently of the general intensity
used for levels, monsters etc.
fixes#189
When applied to y SURF_FLOWING textures are scrolled into the wrong
direction. I guess that in GL1 the offset is also applied to x.
This fixes issue #186.
Sometimes cinematics are skipped after the first frame even if the
player didn't press any key. I'm unable to reliable reproduce that,
so my educated guess is that one or more events are still waiting in
SDLs event queue.
For example, during intermission IN_Update() is not called for 5
seconds, key presses by impatient players are just added to the queue
and not processed. The first event is used to skip leave the
intermission, the second event skips the cinematic...
Fix this by implementing a new function IN_FlushQueue() to flush SDLs
event queue and calling it when starting cinematic playback. Yes, this
is just another layer violation. :(
When the client is paused (either explicit or by entering the menu or
console) the cinematic is paused, too. Therefor no more sound samples
are generated and added to the playback queue, the existing samples are
played over and over again. Until now these samples weren't hearable,
because OpenAL marked them as processed and AL_StreamUpdate() removed
them from OpenALs playback queues. This changed in the previous commit,
now the stay in OpenALs queue and are hearable.
Fix this by calling AL_UnqueueRawSamples() when the menu or console is
entered during cinematic playback.
Newer openal-soft versions changed the way how the processed buffers are
counted when in AL_STOPPED state. Previously only processed buffers were
counted, now all buffers are. Change our unqueue logic to match this new
behavior.
This was debugged and fixed @xorw, I'm just committing the patch. This
closes issue #185.
For some reasons setting the MSAA fails at window creation and not at
GL context creation. And of course SDL is unable to detect before, that
the requested number of MSAA samples is invalid... Implement a work
around: Fall back to gl_msaa_samples == 0 if the window cannot be
created.
The CMakeLists.txt used the same linker flags for all target, grossly
overlinking q2ded and both render libraries. Fix this by introducing
fine grained variables holding the linker flags.
Resurrect support for render / refresher loadable libraries and use them to implement an experimental OpenGL 3.2 renderer. Please note that the new renderer interface is somewhat different from the original one, old render libraries will NOT work!
there's a target_secret (with targetname "t117"), but no one triggers
it - that's why the help computer shows four secrets, but you can only
get three of them.
Now when you open the door in front of the hidden secret armor
(by shooting it), it'll trigger the target_secret and you can get all
four secrets.
fixes#182
The internal order of the items is determined by Menu_AddItem() and
not the y position. Without this change the cursor didn't jump from
item to item, but from the mode list box to the aspect list box,
skipping the brightness slider.
- Bump vid_gamma to 1.2 in both GL1 and GL3. A default value of 1.0 is
too dark.
- Lower gl3_overbrightbits to 1.3, the previous value of 1.5 was too
bright. This can be seen in later units, for example on mine1 some
textures blended into white.
- Lower gl3_particle_size to 40. A value of 60 may be okay, but with
gl3_particle_fade_factor 1.2 the particles take up too much screen
estate in close range combat.
With this changes GL3 looks (at least for me) nearly the same as GL1
rendered through the removed multitexturing path.
Without capping the brightness entity models may fade into pure white
which looks ugly. This can be seen when several flyer fire blaster
bolds onto the player or when multiple barrels are exploding. This
change was suggest by @DanielGibson, I'm just the messenger.
I really don't see why this constraint was ever necessary. It leads to
one line of pixels not rendered either at the bottom or the right edge
of the screen. In GL1 for whatever reasons this line is just black, in
GL3 garbage is drawn.
In SCR_DrawFieldScaled() the HUD scale factor wasn't taken into account
when calculating the screen area affected by the change. Therefor wrong
coordinates were passed to SCR_AddDirtyPoint() and a part of the changed
area wasn't marked dirty, leading to render artifacts.
This bug was present since HUD scaling was first introduced.
