Static arrays there have their dimensions swapped, they make more sense now.
Added important detail in gl1_lightmapcopies doc.
Also added doc for gl_polyblend, just because of its "popularity".
Available in both GL1 and GLES1. Keep multiple copies of "the same"
lightmap on video memory; they are actually different, because they're
used in different frames. This is a workaround for the usage of
glTexSubImage2D() for dynamic lighting, since modifying textures used
recently causes slowdown in embedded/mobile devices.
Controlled by gl1_lightmapcopies cvar; default in GL1 is `0`, while
in GLES1 is `1`.
Available only on GLES1, allows to use a "performance hint" to the
GPU to discard the contents of depth and stencil buffers after each
frame. Some hardware might want to reuse them, but Quake 2 doesn't
work that way.
Controlled by gl1_discardfb cvar, default `1`.
Variant of GL1, meant for embedded/mobile devices only.
Build it with "make with_gles1".
For Windows, you'll need MSYS2 and a decent ANGLE implementation
(probably not worth the trouble).
Building with CMake only works in Linux, so it has been commented out.
Changed "buffer" functions (vertex, single/mtex, color) to macros.
Macros eliminate the function call overhead, resulting in faster
execution times. Depending of the hardware, there might be a
performance increase of almost 10%.
This forced the buffer to be exposed as global.
Not worth doing this for 2D elements though.
glTexSubImage2D() calls are very slow, and are even slower when
the texture is big. Dynamic lighting changes are small compared
to the huge 512x512 size of the lightmap this option provided,
so it was detrimental to performance.
Original logic remains underneath if there's a need of a comeback.
Implemented a batching procedure, to try to group meshes in a buffer
and use a final GL call to draw them all in one step, instead of the
many GL draw calls existing today.
For now, only 2D textures are included, especifically console text
("conchars"), scrap and tiles. It's not worth doing this for
individual 2D elements (e.g. crosshair).
They were in this form:
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG/MIN_FILTER,GL_LINEAR)
Only appeared at startup, but we didn't need so many of them.
ref_gl renders use 0.0..1.0 float texture coordinates in gl commands
and skin ratio/resolution could be any.
ref_soft render uses absolute coordinates as result textures with
different to expected size are applied incorrectly.
Fix will not add support of scalled retextured skins, just fix case
when ratio is incorrect after scale down such or place a incorrect
pcx skin to the model directory.
Soft render still uses downscalled skins and wall, code fixes case
when skin(s,t) size defined in model is slightly different to real
skin dementions. Code checks skin size in model and image asset size
and scale.
The first try didn't take into account that an evil server could
override the filter list by sending a stuff command. Fix this by
hardcoding the filters for .dll, .dylib and .so. Make sure that the
filters are always applied, either when the download is requested
through the `download` command or because game data is missing.
This is just a poor mans fix, trying to rule out an obvious way to
inject code into the client.
Usage of FS_LoadFile as readfile_t is unsupported for now as requires
usage FS_FreeFile instead just copy of file content.
Fixes memory leak for sin models load.
`cl_nodownload_list` is a whitespace seperated list of strings, files
containing one of these strings in their name are never downloaded. Set
to `.dll .dylib .so` by default to prevent downloading libraries which
can be injected into client.
Closes#1114.
Applied too many OpenGL calls for an effect that could not be told
apart from normal GL_MODULATE; explains its absence from Q3A code.
Also, removed calls to glPixelStorei when no dynamic lights present.
With "hand 2" and no "alias" models in player sight, sometimes only
lightmap was visible. Now forcing disabled multitexture when needed.
Another bugfix: "gl_showbbox 1" no longer produces OpenGL errors.
Controlled by gl1_biglightmaps cvar, works like new lightmaps.
Max size is 384x384; a bigger size is not justified.
Added a transparent border so colors from one picture don't bleed
into the next.
Controlled by new cvar, gl1_biglightmaps.
Size is now up to 512x512, for a max quantity of 8 lightmaps.
Should reduce rebinding of them, and reduce the number of calls
to glTexSubImage2D(), although it may increase data transfer on
each call.
Only happens in Windows. A cvar was being queried just after
all cvars were freed, in Qcommon_Shutdown().
GL_GENERATE_MIPMAP definition relocated.
scrap_uploads counter deleted, it wasn't being read anywhere.
Some of files could have name of animation and skin, but some of files
does no have naming of action and textures. Search include file by extention
instead use name + filename format.
Using MH's solution, which is keeping all lightmaps in memory
to modify and upload them as a batch when possible.
lightmap_buffer is now an array; index 0 is used as the legacy
lightmap buffer (when no mtex), and the rest of the indexes are
to store the different lightmaps (only when using mtex).
Unlike the old, buggy one, this implementation follows the
texture chain, just like the standard execution path. It also
avoids doing the lightmap chains, since it has already done it
in the second TMU; there's no duplicated work for lightmaps.
No errors appear in the lava on the "boss1" map either.
It's still slow when having an overdraw of dynamic lights.
Further work is needed.
While it is based on the old, buggy multitexture implementation
(removed in 68a12d4e & 8fe8f832), rework will be done to make it
function as intended this time.
For this commit, just init and function declarations.
Using GL 1.4 declarations in code, although 'point parameters' will
use legacy extensions if they're the only ones found.
Moved stuff out of local.h; better to have definitions in one place.
Extracted from <glext.h>.
Somehow, R_TextureAnimation() returns different results for the same
surface when called consecutively. We force it to be called once, so
the chains in R_DrawTextureChains() are getting respected now.
