The old organization made sense when ZDoom still was a thing but now it'd be better if all pure data with no dependence on renderer implementation details was moved out.
A separation between GL2 and GL3+4 renderers looks to be inevitable and the more data is out of the renderer when that happens, the better.
This was originally invented to fix the sprite offsets for the hardware renderer.
Changed it so that it doesn't override the original offsets but acts as a second set.
A new CVAR has been added to allow controlling the behavior per renderer.
This was done mainly to reduce the amount of occurences of the word FTexture but it immediately helped detect two small and mostly harmless bugs that were found due to the stricter type checks.
These cannot be done with the regular textures so there needs to be an option to create more than one native texture per FTexture. For completeness' sake there is also the option now to create a paletted version of a texture if the regular one is true color. This fixes a long standing problem that translations were not applied to non-paletted textures.
* Instead of using the red channel it now uses the grayscale value. While slower in a few situations, it is also more precise and makes the feature more useful.
* For paletted textures do not use the index as alpha anymore but the actual grayscaled color. This is again to make the feature more consistent and useful.
* To compensate for the above there is now a list of hashes for known alpha textures in patch format, so that they don't get broken.
* IMGZ is now considered a grayscale format. There's only two known textures that use IMGZ for something else than crosshairs and those are explicitly handled.
* several smaller fixes.
* the actual color conversion functions for paletted output are now consolidated in a small number of inlines so that future changes are easier to do.
Note: This hasn't been tested yet and will need further changes in the hardware rendering code. As it is it is not production-ready.
Now it is no longer necessary to provide specially set up textures for rendering shaded decals, they can use any PNG texture now that contains a proper red channel.
Handling of the alPh chunk has been removed as a result as it in no longer needed.
Until now each subclass of FTexture had to implement the entire span generation itself, presumably so that a few classes can use simpler structures.
This does not work if a texture can have more than one pixel buffer as is needed for alpha textures.
Even though it means that some classes will allocate more data now, it's the only way to do it properly.
In addition this removes a significant amount of mostly redundant code from the texture classes.
- added alpha texture processing to all converted classes
As of now this is not active and not tested.
Note that as part of the conversion even those textures that were working as alphatextures will not look correct until the higher level code gets adjusted.
Most of those which still rely on ZDoom's own definition should be gone, unfortunately the code in files that include Windows headers is a gigantic mess with DWORDs being longs there intead of ints, so this needs to be done with care. DWORD should only remain where the Windows type is actually wanted.
Fix crash due to dc_source2 not always being set
Add r_lod_bias to control mipmap selection
Improve LOD calculations to take the U texture coordinate into account
- These require manual detection and overriding of the scaling factors to
0, because a right shift of (32-0) bits wraps around to 0 and results in
no shift at all rather than leaving the register zeroed out.
- Fixed: If a part of a multipatch texture is replaced by a HIRESTEX
version, the original patch must not be deleted, since the multipatch
texture still needs it for compositing.
ignored the Y locations of patches drawn on two-sided midtextures and always drew them at the
top of the texture. Added a compatibility flag.
SVN r3205 (trunk)
only has 64 entries and is not precise enough. It now uses finesine instead.
- fixed: When compositing a multipatch texture any patch that is a multpatch
texture itself and contains rotations may not be composited directly into
the destination buffer. This must be done with an intermediate buffer.
- Fixed: Drawing a slider in the options menu did not scale the x-coordinate.
- Fixed: If the alt HUD had to draw negative numbers the minus sign was misplaced
due to incorrect texture coordinate calculations.
- changed option menu scaling for widescreen modes so that it doesn't scale down
so quickly.
- made some error messages in DECORATE that don't affect the parsing non-fatal
so that the parser can continue to find more problems.
SVN r2076 (trunk)
for true color. Instead of using a clipping rectangle on the destination it
tried to alter the source offsets which produced incorrect results for
mirrored or rotated patches.
SVN r1889 (trunk)
texture manager. They now get assigned a new FEmptyTexture object
that is just a 1x1 pixel transparent texture.
- Fixed: Multiple namespace markers of the same type were no longer detected.
- Fixed sprite renaming.
SVN r1566 (trunk)
hash chains.
- Fixed: specifying texture patches or font characters by full lump name instead
of texture name didn't work. To do this properly the texture manager needs
an option to look for a texture by lump number so that such textures can
be maintained without interfering with regular operation.
- added 'skystretch' and 'autosequences' keywords for MAPINFO so that the effects
of 'noautosequences' and 'forcenoskystretch' can be cancelled.
- Added a 'gamedefaults' section to MAPINFO after discovering that 'defaultmap'
gets reset for each MAPINFO. A global section is needed to define a game's
default setting in zdoom.pk3. The gamedefaults should normally not be changed
by PWADs but it can be done if some mod intends to change gameplay settings
but wants to allow custom add-ons on its own.
SVN r1300 (trunk)
- Fixed: The recent changes in the DECORATE parser require the special parameter
to A_CallSpecial to be an expression, not a constant.
- Removed game filters from old style decorations. No WAD in existence ever
used them and removing them allows to make the parser more robust.
SVN r1170 (trunk)
the texture manager even if it is from Raven's IWADs.
- Removed code related to internal ActorInfo definitions from dobjtype.cpp.
- removed unneeded file dehackedactions.h
SVN r1162 (trunk)
They are not needed anywhere else.
- Changed the HackHack hack for corrupt 256 pixel high textures that
FMultiPatchTexture only calls a virtual function instead of doing any
type checks of the patch itself.
- Cleaned up the constant definitions in doomdata.h.
- Moved the TEXTUREx structures from doomdata.h to multipatchtexture.cpp
because they are used only in this one file.
- Removed some more typedefs from r_defs.h and doomdata.h
- Moved local polyobject data definitions from p_local.h to po_man.cpp.
SVN r1012 (trunk)
- Also changed all true color texture creation functions to use proper alpha
values instead of inverted ones.
- Changed FRemapTable so that all palette entries must contain proper alpha
values.
- Fixed: The F1 screen check in m_menu.cpp was missing a NULL pointer check.
- Changed: The boss brain's explosions play weapons/rocklx which is an
unlimited sound. This can become extremely loud. Replaced with a new
sound which is just an alias to weapons/rocklx but has a limit of 4.
SVN r932 (trunk)
- Reorganized the HackHack code so that the image creation was moved into
MakeTexture. This was necessary because Unload deleted the pixel data
and broke the whole thing.
- Fixed: FPatchTexture::HackHack and FDoomStatusbarTexture::DrawToBar used the
obsolete and uninitialized variable Near255.
- Removed the span creation code specific to FPatchTexture. It only has an
advantage when the lump has already been loaded in memory but since that
is no longer the case now the generic version in FTexture is actually better.
- Changed: FTexture::CopyToBlock no longer uses the spans but the pixel buffer
directly. Since most patches in multipatch textures are non transparent
the added overhead from creating the spans far outweighs any savings they
might provide. It is also simpler to handle for mirrored or rotated patches now.
- Changed: Textures only create the spans when really needed. Flats and native
textures, for example, do not and it only created needless overhead that they
were always created along with the pixel buffer.
- Made use of player and actor variables consistent in a_hereticweaps.cpp.
- Fixed: A few calls to P_SpawnPlayerMissile passed 0 as angle
SVN r911 (trunk)
command actually existed.
- Fixed: My $Limit fix from yesterday didn't work because NearLimit was
an unsigned byte and the comparisons with -1 didn't work. Made it a
signed word instead.
- Made sfxinfo_t::Link an unsigned int because it limited the amount of
usable sounds to 65535.
SVN r869 (trunk)
- Fixed: The MusicVolumes list was allocated with M_Malloc but freed with
delete.
- Fixed: demobuffer was inconsistantly handled with new[]/delete[] and
malloc/free.
- Added used memory tracking to M_Malloc() and M_Realloc(). This
necessitated the addition of an M_Free() call to track frees.
- Removed M_Calloc since it was only used in one place, and can just as well
be done with an M_Malloc/memset pair.
- Bumped DEMOGAMEVERSION for the new net controller codes.
SVN r751 (trunk)
as the empty string. Since that was the player class, this meant that any
games with more than one class would pick a random class in multiplayer.
- Fixed: FCanvasTexture::RenderView() should not have color 0 in its output.
SVN r735 (trunk)
- Got rid of R_InitPatches because the new texture init code needs to preload
everything to work correctly.
- Rewrote texture manager initialization to order textures primarily by WAD
rather than by type. This way later textures will always override earlier
ones. The only exception is that TEX_MiscPatch are only used as a fallback
if nothing else can be found.
- Optimized the tryany case of FTextureManager::CheckForTexture. It is not
necessary to scan the hash chain twice. The required information can be
retrieved during the first pass as easily and even offers a little more
control.
- Made FFont destructor virtual.
- Added 'Ice' translation to DECORATE.
(Caution: Not fully tested yet!)

can share the same hardware texture. This greatly reduces the number of
DrawPrimitive calls that need to be made when drawing text (or any 2D
graphics in general), so now hardware text is much faster than software text
all around. (As an example, one scenario went from 315 fps to over 1635 fps
for hardware, compared to 540 fps for software.)
SVN r687 (trunk)
drawn to a texture, then that texture is copied to the real back buffer
using a gamma-correcting pixel shader. In fullscreen mode, SetGammaRamp
is used.
- Fixed flashing of vid_fps display when fps > 1000.
- Fixed loading of RGB textures for native 2D mode.
- Changed the first rotozoomer's data because it just became too obvious when
the backdrop is drawn with a full 256 distinct colors available.
- Set the player backdrop to update no more frequently than 35 FPS, so opening
the player setup menu before starting a game won't produce a very fast
moving backdrop.
- Changed the player backdrop into a texture so that it can be drawn like
anything else.
SVN r648 (trunk)
palettes smaller than 256 entries with the shader I wrote for it. Is there
a list of gotchas like this listed some where? I'd really like to see it.
Well, when compiled with SM2.0, the PalTex shader seems to be every-so-
slightly faster on my GF7950GT than the SM1.4 version, so I guess it's a
minor win for cards that support it.
- Fixed: ST_Endoom() failed to free the bitmap it used.
- Added the DTA_ColorOverlay attribute to blend a color with the texture
being drawn. For software, this (currently) only works with black. For
hardware, it works with any color. The motiviation for this was so I could
rewrite the status bar calls that passed DIM_MAP to DTA_Translation to
draw darker icons into something that didn't require making a whole new
remap table.
- After having an "OMG! How could I have been so stupid?" moment, I have
removed the off-by-one check from D3DFB. I had thought the off-by-one error
was caused by rounding errors by the shader hardware. Not so. Rather, I
wasn't sampling what I thought I was sampling. A texture that uses palette
index 255 passes the value 1.0 to the shader. The shader needs to adjust the
range of its palette indexes, or it will end up trying to read color 256
from the palette texture when it should be reading color 255. Doh!
- The TranslationToTable() function has been added to map from translation
numbers used by actors to the tables those numbers represent. This function
performs validation for the input and returns NULL if the input value
is invalid.
- Major changes to the way translation tables work: No longer are they each a
256-byte array. Instead, the FRemapTable structure is used to represent each
one. It includes a remap array for the software renderer, a palette array
for a hardware renderer, and a native texture pointer for D3DFB. The
translationtables array itself is now an array of TArrays that point to the
real tables. The DTA_Translation attribute must also be passed a pointer
to a FRemapTable, not a byte array as previously.
- Modified DFrameBuffer::DrawRateStuff() so that it can do its thing properly
for D3DFB's 2D mode. Before, any fullscreen graphics (like help images)
covered it up.
SVN r640 (trunk)
if present.
- Modified GZDoom's true color texture copy functions and added them
to generate 32 bit D3D textures. Paletted TGAs and PCXs are also handled
this way but I don't think these 2 formats are worth some more special
handling.
(Question: Is it worth it to implement special handling for paletted PNGs
so that they are used as 8 bit textures internally?)
SVN r608 (trunk)
They are not actually drawn with it yet, nor is it complete, but it's
something to start with.
- Split up DCanvas::DrawTexture() into more pieces to make it easier to
virtualize.
- Removed support for non-32-bit palette textures from D3DFB. What kind of
card supports pixel shaders but not 32-bit textures?
SVN r605 (trunk)
I got rid of the old tx and ty CVARs because they made the texture scaling
much more complicated than it was actually needed (and besides, they were completely
useless except for testing purposes anyway.)
SVN r522 (trunk)
bWorldPanning flag. Also added some NULL pointer checks to the
hires texture loading code.
- Added Sector_SetFloorScale2 and Sector_SetCeilingScale2 line specials.
They are mostly the same as Sector_Set*Scale but take fixed point parameters.
This makes them easier to use and more precise than the old ones which
offered very small fractional precision.
- Changed Thing_Deactivate so that passing a tid of 0 deactivates the calling
actor.
- Added MeansOfDeath parameter to DamageThing.
SVN r350 (trunk)
data file.
- Removed the setcolor CCMD. It's been obsolete for years, ever since color-
aware cvars were added.
- Changed V_GetColorStringByName() to return an FString, because it did a
copystring() call.
- Extended V_GetColorFromString() so that it accepts HTML-style #RRGGBB and
#RGB color strings.
SVN r313 (trunk)
The lump is open anyway at that time so deferring this action until the information
is needed doesn't give any speed improvements. Now GetDimensions and all its
associated overhead is gone.
- Added support for TGA textures. It can handle all of the common variations
of this format.
- Changed: GI_PAGESARERAW is no longer checked. It wasn't really necessary before
because the chance of texture misidentification is absolutely minimal.
But raw pages are now restricted to textures of type TEX_MiscPatch only.
- Changed the automap parchment to use a regular texture. The previous
FAutomapTexture is only used as a last resort fallback now. If the code
finds a recognizable graphic it will create a proper texture for it now.
- Fixed: Flats were only auto-scaled when in Doom flat format.
- Fixed: FMultiPatchTexture::CheckForHacks blindly assumed that all patches
were FPstchTextures. Since the texture code does not have any type information
I added a new flag bIsPatch for this purpose.
- Moved all texture classes into their own source files and created a new
subdirectory 'textures' for that.
- Cleaned up the texture management code and added some stricter checks for
the validity of Doom patches. The old code liked to crash when being passed
some non-graphic data.
