which just called R_PolyBlend().. no idea what that all was about..
and no idea why it happend in 3D mode, it's much easier after
SetGL2D(), then it can share code with GL3_Draw_FadeScreen() and doesn't
need any additional messing with transformation matrices
* The particles look more fuzzy than in old renderer - I think it looks
better this way ;)
* Not sure I keep the way they're rendered - instead of calculating and
passing the distance in GL3_ShutdownShaders() I could set the player
(camera) origin in a UBO and calculate distance (and based on that
the size) in the vertex shader. I could also pass the basic point size
via UBO, it's the same for all particles..
* Deleting shader programs is a lot shorter now and using a loop and
the fact that consecutive fields of the same type in a struct have
the same memory layout as an array of that type.
Now I can just add a gl3ShaderInfo_t to gl3state, set it up in
GL3_InitShaders() and don't have to add anything to
GL3_ShutdownShaders() (this is good, I forgot that all the time and
didn't notice, as it doesn't cause visible errors)
* Of course the color attribute has 4 floats, not 2..
* I read that updating UBOs with glBufferData() is kinda slow.
I didn't change that (yet), but at least all three GL3_UpdateUBO*()
functions now call updateUBO() which can easily be changed to do
whatever is best without touching the other three functions.
* When using gl_pointparameters, the particles always had the same size
regardless of resolution, i.e. they look bigger (use bigger part of
screen) at lower resolutions. Now I scale gl_particle_size according
to the resolution, assuming the configured size looks good at 800x600
(or generally 600px vertical)
* When not using gl_pointparameters, a textured triangle is rendered.
The texture had a resolution of 8x8 pixels and looked like a cross,
now it's 16x16 and has rounded ages, looking more like a circle.
So particles with "gl_pointparameters 0" should look much better now.
turns out R_MYgluPerspective() was not the same as gluPerspective()
and thus not equivalent to HMM_Perspective() either. Because of this,
the weapon and corresponding arm looked different in GL3 vs GL1.
Created GL3_MYgluPerspective() to fix that.
Also tested optimized code in GL3_RotateForEntity() and
rotAroundAxisZYX(), use this code from now on and cleaned it all up by
removing commented out code.
that was easy..
however, not related to this change or left vs right hand, the gun
seems to be drawn too far back, we should see more of the arm..
I wonder where that went wrong...
introducing vertex color attributes GL3_ATTRIB_COLOR (it's used for
lighting models and to render models flat-colored, I think that's used
for quad damage effect and similar)
kind of messy commit with all the shit from last weekend, finished now
Most importantly the common vertex attribute layout stuff using
glBindAttribLocation()
still no 3D rendering, but in theory it should be able to load models,
bsps etc, just not render them yet.
also moved/copied md2.c and sp2.c to gl/ and gl3/ because they use
renderer-specific types
only for 2D rendering, as we don't have 3D yet; also this might need
a more flexible solution later, as some textures are not supposed to
have intensity applied.
According to the old R_Upload32*() and R_LightScaleTexture() the ones
without mipmaps didn't get intensity. Those were it_pic and it_sky (and
the ones in the "scrap", but those were it_pic too)
when called from R_FindImage() the palette wasn't used anyway.
R_FindImage() now passes NULL.
(LoadPCX() is still called with non-NULL palette from Draw_GetPalette())
the arguments were not used anyway, and returning true/false is clearer
than returning -1 (for error) or sth else (which has no deeper meaning
anyway).
Also:
* PrepareForWindow() can now return -1 if there's an error
* suppress some warnings in Makefile
* fix error for building ref_gl.dylib on OSX
So in all code in the reflib (ref_gl.dll/.so/.dylib) calls to
ri.Con_Printf(print_level, fmt, ...) have been replaced by calls to
R_Printf(print_level, fmt, ...) which uses ri.Com_VPrintf().
somehow all the printf()-like things in Q2 wrap each other and each
one prints into a buffer and then calls the next one with ("%s", buf).
That's not very clever and kinda annoying.
As in the end everyone calls Com_Printf() I created Com_VPrintf()
that can be called instead with the va_list.
I also added printf-format annotation to Com_Printf() and Com_DPrintf()
and fixed places where Com_Printf() was called with the wrong type.
and the changes in the including files for this.
(also removed gl.h includes from local.h, as it's already included in
qgl.h which is included by local.h)
the problem is that sdl2-config --libs apparently includes shit that's only
useful for the executable, but not dlls, like linking against SDL2main and
libmingw32 and setting -mwindows
Furthermore I forgot to add -lopengl32 and -shared to the ref_gl Windows
LDFLAGS.
When the monster was already killed by another monster or a coop player
some references may be NULL and the game was crashed. This was observed
by maraakte, who reported it in issue #164. I've just merged his fix
from q2dos.
Repeat 10 times:
- strcat() is evil

While here fix another small inconsistency: Vorbis playback should
stop when switching 'shuffle' on.
The overflow was reported by @tomgreen66 in pull request #168.
