surfaces are alternately locked for read-only access each frame, forcing
the driver to stop buffering more than one frame at a time. The input lag
on my system doesn't seem to be as bad as it once was (I can no longer
see it obviously with my naked eye), but turning antilag on "feels"
slightly more responsive. The cvar d3d_antilag turns this technique on and
off. See <http://www.xyzw.de/c120.html> for more details.

which could cause crashes.
- Added custom special colormaps to DECORATE.
- Cleaned up special colormap code and removed lots of dependencies on the
knowledge of the tables' contents.
SVN r1860 (trunk)
completely ignore them, either).
- Separated light level fixing out of player_t's fixedcolormap parameter.
Using a fixed light level (e.g. PowerTorch) will no longer wipe out
colored lighting.
- Moved the blending rectangle drawing into a separate discrete stage, since
doing it while copying the 3D view window to the display now blends
underneath the weapon instead of on top of it.
- Consolidated the special colormaps into a single 2D table.
- Tweaked the special colormaps slightly to make the true color results more
closely match the paletted approximations.
- fb_d3d9_shaders.h was getting unwieldy, so I moved the shaders out of the
executable and into zdoom.pk3. Shaders are still precompiled so I don't need
to pull in a dependancy on D3DX.
- Added a few more shaders to accomodate drawing weapons with all the in-game
lighting models. These are accessed with the new DrawTexture tags
DTA_SpecialColormap and DTA_ColormapStyle.
- Player weapon sprites are now drawn using Direct3D and receive all the
benefits thereof.
SVN r1858 (trunk)
so that all files are included by a central one instead of compiling
each one separately. This speeds up the compilation process by 25%
when doing a complete rebuild in Visual C.
- Cleaned up more header dependencies.

fact that NVidia's don't report it, even though they support it. If there
are any cards that no longer have antialised lines on the automap, please
let me know.
- Added vid_hwaalines cvar to force antialiased lines off for the
Direct3D renderer, in case it doesn't really support them.
SVN r1210 (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)
that the drivers will treat a BackBufferCount of 0 as a request for
double buffering.
- Fixed: Unsetting a cvar did not remove it from the list of tab
completions.
- Added "" as a synonym for "nullimage" in SBARINFO.
- Fixed: MAKESAVESIG's stringifier in version.h did not work as expected.
It stringified the passed macro name, not the value of the macro.
- Moved DCajunMaster off the DObject hierarchy.
- Changed DCajunMaster::getspawned into a TArray of FStrings. It was
mysteriously being left pointing to uninitialized memory during the
final GC at exit and crashing.
- Fixed: The code that removed hexdd.wad from the list of IWADs when
hexen.wad was not present did not work.
SVN r861 (trunk)
- Disabled console alpha when the console is fullscreen.
- Re-enabled maybedrawnow for the software renderer. This should be replaced
with a different progress bar implementation at some point that can work
with hardware graphics.
SVN r747 (trunk)
frame to avoid the remote possibility that it could change during the middle
of drawing the frame and cause strange things to happen.
- Renamed test2d to vid_hw2d.
SVN r744 (trunk)
- Added .txt files to the list of types (wad, zip, and pk3) that can be
loaded without listing them after -file.
- Fonts that are created by the ACS setfont command to wrap a texture now
support animated textures.
- FON2 fonts can now use their full palette for CR_UNTRANSLATED when drawn
with the hardware 2D path instead of being restricted to the game palette.
- Fixed: Toggling vid_vsync would reset the displayed fullscreen gamma to 1
on a Radeon 9000.
- Added back the off-by-one palette handling, but in a much more limited
scope than before. The skipped entry is assumed to always be at 248, and
it is assumed that all Shader Model 1.4 cards suffer from this. That's
because all SM1.4 cards are based on variants of the ATI R200 core, and the
RV250 in a Radeon 9000 craps up like this. I see no reason to assume that
other flavors of the R200 are any different. (Interesting note: With the
Radeon 9000, D3DTADDRESS_CLAMP is an invalid address mode when using the
debug Direct3D 9 runtime, but it works perfectly fine with the retail
Direct3D 9 runtime.) (Insight: The R200 probably uses bytes for all its
math inside pixel shaders. That would explain perfectly why I can't use
constants greater than 1 with PS1.4 and why it can't do an exact mapping to
every entry in the color palette.
- Fixed: The software shaded drawer did not work for 2D, because its selected
"color"map was replaced with the identitymap before being used.
- Fixed: I cannot use Printf to output messages before the framebuffer was
completely setup, meaning that Shader Model 1.4 cards could not change
resolution.
- I have decided to let remap palettes specify variable alpha values for
their colors. D3DFB no longer forces them to 255.
- Updated re2c to version 0.12.3.
- Fixed: A_Wander used threshold as a timer, when it should have used
reactiontime.
- Fixed: A_CustomRailgun would not fire at all for actors without a target
when the aim parameter was disabled.
- Made the warp command work in multiplayer, again courtesy of Karate Chris.
- Fixed: Trying to spawn a bot while not in a game made for a crashing time.
(Patch courtesy of Karate Chris.)
- Removed some floating point math from hu_scores.cpp that somebody's GCC
gave warnings for (not mine, though).
- Fixed: The SBarInfo drawbar command crashed if the sprite image was
unavailable.
- Fixed: FString::operator=(const char *) did not release its old buffer when
being assigned to the null string.
- The scanner no longer has an upper limit on the length of strings it
accepts, though short strings will be faster than long ones.
- Moved all the text scanning functions into a class. Mainly, this means that
multiple script scanner states can be stored without being forced to do so
recursively. I think I might be taking advantage of that in the near
future. Possibly. Maybe.
- Removed some potential buffer overflows from the decal parser.
- Applied Blzut3's SBARINFO update #9:
* Fixed: When using even length values in drawnumber it would cap to a 98
value instead of a 99 as intended.
* The SBarInfo parser can now accept negatives for coordinates. This
doesn't allow much right now, but later I plan to add better fullscreen
hud support in which the negatives will be more useful. This also cleans
up the source a bit since all calls for (x, y) coordinates are with the
function getCoordinates().
- Added support for stencilling actors.
- Added support for non-black colors specified with DTA_ColorOverlay to the
software renderer.
- Fixed: The inverse, gold, red, and green fixed colormaps each allocated
space for 32 different colormaps, even though each only used the first one.
- Added two new blending flags to make reverse subtract blending more useful:
STYLEF_InvertSource and STYLEF_InvertOverlay. These invert the color that
gets blended with the background, since that seems like a good idea for
reverse subtraction. They also work with the other two blending operations.
- Added subtract and reverse subtract blending operations to the renderer.
Since the ERenderStyle enumeration was getting rather unwieldy, I converted
it into a new FRenderStyle structure that lets each parameter of the
blending equation be set separately. This simplified the set up for the
blend quite a bit, and it means a number of new combinations are available
by setting the parameters properly.

* Fixed: Drawbar had a few memory leaks.
- Added another temporary cvar called pc to play with the multipiler used by D3DFB::SetPaletteTexture().
SVN r704 (trunk)
truncate the coordinates to integers before sending them to the hardware.
Otherwise, there can be one pixel gaps compared to the software renderer,
because the hardware is rounding to nearest but the software renderer is
simply truncating the fractional part of the coordinate. This is the real
cause of the gap above the status bar at 1152x864 (and another gap to the
left of the status bar at 800x500).
- Fixed: When D3DFB::DrawTextureV had to clip a tile, it adjusted the
texture coordinates erroneously, still using the old calculations from
before texture packing was implemented.
SVN r695 (trunk)
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)
- Modified M_DrawFrame() and R_DrawTopBorder() so that they call FlatFill() to
draw the edges of the frames. This at least seems a bit faster for hardware
2D.
- Implemented FlatFill() for D3DFB. It seems to be exactly as fast as the
default implementation that just calls DrawTexture() to tile the pieces onto
the screen, so I'm not sure it was worth the bother.
SVN r686 (trunk)
vertex buffer, made line batching automatic, and added an index buffer for
use when batching quads. The index buffer actually offered more of a
performance boost than simply batching the quads alone did.
SVN r685 (trunk)
players are on teams.
- Set TEAM_None back to 255. Since a player's team has already been accessible
through ACS, needlessly redefining this is a bad thing to do, since it can
break existing maps. 255 different teams should still be more than enough.
- Fixed: At certain resolutions, there was a one pixel row between the status
bar and the rest of the screen, thanks to rounding error.
- Added automatic batching of quads to D3DFB. Screens with a lot of text are
ever-so-slightly faster now, though still only about half the speed of
sofware-only text. I suppose the only way to see a marked improvement is
going to be by stuffing multiple glyphs in a single texture.
- Fixed: Crosshairgrow's animation was not framerate-independent.
SVN r668 (trunk)
and into the vertex data.
- Added functions for doing line drawing with Direct3D, including a new pair
of functions to do batched line drawing so that the map can actually be
drawn faster in hardware than in software (instead of an order of magnitude
slower).
SVN r663 (trunk)
shader seems to be producing crappy output, so it's disabled for now.
Specifically, it produces distorted output at regular intervals for
textures that aren't power-of-2-sized, and it's still doing visible
filtering when the texture is rendered at its original size, so
obviously it's not doing something right.
- Fixed the use of power-of-2-sized native textures for smaller game
textures again.
- Fixed: D3DFB did not restore all the state it needed to after resetting
the device.
- Fixed: R_DrawTopBorder() must clip itself around the 3D view, since it's
now drawn later.
- With full software rendering, palette flashes once again effect the whole
screen.
Changes I neglected to put in the previous commit log:
- Moved the view border drawing into the 2D mode part. When using Begin2D()
now, the only part of the software buffer that gets updated to the screen
is the part with the actual 3D scene and only if you tell it to.
- Fixed a D3D memory leak on every frame in windowed mode and the same thing
for the screen wipes. Note to self: If it's an interface, be sure to
Release it, because it will be AddRef'ed before being returned to you.
- Moved the BlendView() call out of FBaseStatusBar::Draw() so that it can be
applied before copying the 3D scene to the screen underneath the 2D parts.
- Restored the console's darkening level to its old table-based amount.
- Fixed D3DFB::SetColorOverlay()'s incorrect calculations.
- Fixed the D3D screen wipes for letterboxed modes.
SVN r662 (trunk)
since I couldn't think of any reason why it should be grabbed at any other
time. (This only applies to windowed mode, where it makes sense to let the
OS have control of the pointer.)
SVN r661 (trunk)
a long-abandoned experiment to write directly to video memory instead of
to a temporary buffer in system meroy.
- Added Direct3D versions of the melt and burn screenwipes.
- Fixed the strip sizes for the melt screenwipe to match what Doom would have
produced on a 320x200 screen, rather than producing more, thinner strips
for wider screens.
SVN r659 (trunk)
allocated. (I wonder if D3D actually handles this automatically when you use
D3DPOOL_MANAGED, because I'm pretty sure my laptops's x300 doesn't support
non-power-of-2 texture sizes, yet it worked just fine before.)
- Fixed vertical positioning of 2D elements in letterboxed modes.
SVN r653 (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)
- Moved the common code of ACS and DECORATE translation generation into the
FRemapTable class.
- Fixed: The DECORATE translation code was not changed for the new data structures.
- Expanded range of ACS and DECORATE translations to 65535.
- Fixed: R_CopyTranslation was not altered for the new functionality.
I removed the function and replaced the one use with a simple assignment.
SVN r644 (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)
- Added a new color parameter to DCanvas::Clear() that specifies the
ARGB value of the color. This is used if the old color parameter,
which specifies a palette entry, is -1.
SVN r617 (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)
position when not playing in fullscreen mode.
- Changed the upper-left window positioning that was always used in debug
builds into a command line option (-0), so debug and release builds behave
the same.
SVN r482 (trunk)
Normally Direct3D sets the FPU to single precision. We don't want that,
since it can mean going out of sync with machines that are using the
standard precision. Additionally, the nodebuilder requires the extra
precision that single precision lacks.
SVN r455 (trunk)
warnings. At first, I was going to try and clean them all up. Then I decided
that was a worthless cause and went about just acting on the ones that
might actually be helpful:
C4189 (local variable is initialized but not referenced)
C4702 (unreachable code)
C4512 (assignment operator could not be generated)
SVN r420 (trunk)
otherwise it gets reset to black and unused.
- Fixed: I_SetWndProc() needs to be called before any of the DirectX
interfaces are initialized, because DirectX subclasses the window itself,
and I_SetWndProc() undoes that subclassing.
SVN r419 (trunk)
be surprised if it doesn't work.
- Reorganized the network startup loops so now they are event driven. There is
a single function that gets called to drive it, and it uses callbacks to
perform the different stages of the synchronization. This lets me have a nice,
responsive abort button instead of the previous unannounced hit-escape-to-
abort behavior, and I think the rearranged code is slightly easier to
understand too.
- Increased the number of bytes for version info during D_ArbitrateNetStart(),
in preparation for the day when NETGAMEVERSION requires more than one byte.
- I noticed an issue with Vista RC1 and the new fatal error setup. Even after
releasing a DirectDraw or Direct3D interface, the DWM can still use the
last image drawn using them when it composites the window. It doesn't always
do it but it does often enough that it is a real problem. At this point, I
don't know if it's a problem with the release version of Vista or not.
After messing around, I discovered the problem was caused by ~Win32Video()
hiding the window and then having it immediately shown soon after. The DWM
kept an image of the window to do the transition effect with, and then when
it didn't get a chance to do the transition, it didn't properly forget about
its saved image and kept plastering it on top of everything else
underneath.
- Added a network synchronization panel to the window during netgame startup.
- Fixed: PClass::CreateDerivedClass() must initialize StateList to NULL.
Otherwise, classic DECORATE definitions generate a big, fat crash.
- Resurrected the R_Init progress bar, now as a standard Windows control.
- Removed the sound failure dialog. The FMOD setup already defaulted to no
sound if initialization failed, so this only applies when snd_output is set
to "alternate" which now also falls back to no sound. In addition, it wasn't
working right, and I didn't feel like fixing it for the probably 0% of users
it affected.
- Fixed: The edit control used for logging output added text in reverse order
on Win9x.
- Went back to the roots and made graphics initialization one of the last
things to happen during setup. Now the startup text is visible again. More
importantly, the main window is no longer created invisible, which seems
to cause trouble with it not always appearing in the taskbar. The fatal
error dialog is now also embedded in the main window instead of being a
separate modal dialog, so you can play with the log window to see any
problems that might be reported there.
Rather than completely restoring the original startup order, I tried to
keep things as close to the way they were with early graphics startup. In
particular, V_Init() now creates a dummy screen so that things that need
screen dimensions can get them. It gets replaced by the real screen later
in I_InitGraphics(). Will need to check this under Linux to make sure it
didn't cause any problems there.
- Removed the following stubs that just called functions in Video:
- I_StartModeIterator()
- I_NextMode()
- I_DisplayType()
I_FullscreenChanged() was also removed, and a new fullscreen parameter
was added to IVideo::StartModeIterator(), since that's all it controlled.
- Renamed I_InitHardware() back to I_InitGraphics(), since that's all it's
initialized post-1.22.
SVN r416 (trunk)
- Fixed: If the FBTexture wasn't exactly the same size as the screen,
D3DFB::PaintToWindow() would still lock it with D3DLOCK_DISCARD. Alas,
I saw no speedup for using a dirty region. (Side note: The Radeons are
apparently slower compared to DirectDraw because they must do
power-of-2 textures. If they ever add non-power-of-2 support like nvidia,
I assume they will also see a speed gain.)
- Changed fb_d3d9.cpp so that instead of trying to compensate for Geforce
off-by-one errors in the pixel shader, it automatically detects where
the error occurs and modifies the way the palette is uploaded to
compensate. Palette color 255 is then represented using the texture
border color instead of actually being part of the palette. This should
work correctly with all cards, since I had a report of an FX where the
off-by-one occurred in a different spot from the place where I observed
it on a 6 and 7 series cards. Since the shader now has one fewer
instruction, I notice a very marginal speedup. (Interestingly, removing
the flash blending from the shader had no perceivable performance gain.)
SVN r399 (trunk)
to PO_MovePolyobj() from P_SerializePolyobjs() for a crushing polyobject
that touches a player actor will not have a valid actor->player->mo chain
for P_DamageMobj and crash if it happens to touch the player. Since the
polyobject was presumably in a good spot when the game was saved, we can
just skip this step entirely and let it take care of itself the next time
it moves (by which time, the players will be valid).
- Fixed: When transitioning from fullscreen to windowed mode with D3DFB, the
window kept the WS_EX_TOPMOST style.
- Slight correctness fix: When in fullscreen, the window should have WS_POPUP
style.
- Added a NULL target check to P_SpawnMissileXYZ(), A_DemonAttack1(),
A_DemonAttack2_1(), and A_DemonAttack2_2().
