Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,

//// crt-royale, by TroggleMonkey <trogglemonkey@gmx.com> ////
//// Last Updated: August 16, 2014 ////
////////////////////////////////////////////////////////////////////////////////
REQUIREMENTS:
The earliest official Retroarch version fully supporting crt-royale is 1.0.0.3
(currently unreleased). Earlier versions lack shader parameters and proper
mipmapping and sRGB support, but the shader may still run at reduced quality.
The earliest development version fully supporting this shader is:
commit ba40be909913c9ccc34dab5d452fba4fe61af9d0
Author: Themaister <maister@archlinux.us>
Date: Thu Jun 5 17:41:10 2014 +0200
A few earlier revisions support the required features, but they may be buggier.
BASICS:
crt-royale is a highly customizable CRT shader for Retroarch and other programs
supporting the libretro Cg shader standard. It uses a number of nonstandardized
extensions like sRGB FBO's, mipmapping, and runtime shader parameters, but
hopefully it will run without much of a fuss on new implementations of the
standard as well.
There are a huge number of parameters. Among the things you can customize:
* Phosphor mask type: An aperture grille, slot mask, and shadow mask are each
included, although the latter won't be seeing much usage until 1440p displays
and better become more common (4k UHD and 8k UHD are increasingly optimal).
* Phosphor mask dot pitch
* Phosphor mask resampling method: Choose between Lanczos sinc resizing,
mipmapped hardware resizing, and no resizing of the input LUT.
* Phosphor bloom softness and type (real or fake ;))
* Gaussian and generalized Gaussian scanline beam properties/distribution,
including convergence offsets
* Screen geometry, including curvature (spherical, alternative spherical, or
cylindrical like Trinitrons), tilt, and borders
* Antialiasing level, resampling filter, and sharpness parameters for gracefully
combining screen curvature with high-frequency phosphor details, including
optionally resampling based on RGB subpixel positions.
* Halation (electrons bouncing under the glass and lighting random phosphors)
random phosphors)
* Refractive diffusion (light spreading from the imperfect CRT glass face)
* Interlacing options
* etc.
There are two major ways to customize the shader:
* Runtime shader parameters allow convenient experimentation with real-time
feedback, but they are much slower, because they prevent static evaluation of
a lot of math. Disabling them drastically speeds up the shader.
* If runtime shader parameters are disabled (partially or totally), those same
settings can be freely altered in the text of the user-settings.h file. There
are also a number of other static-only settings, including the #define macros
which indicate where and when to allow runtime shader parameters. To disable
them entirely, comment out the "#define RUNTIME_SHADER_PARAMS_ENABLE" line by
putting a double-slash ("//") at the beginning...your FPS will skyrocket.
You may also note that there are two major versions of the shader preset:
* crt-royale.cgh is the "full" version of the shader, which blooms the light
from the brighter phosphors to maintain brightness and avoid clipping.
* crt-royale-fake-bloom.cgh is the "cheater's" version of the shader, which
only fakes the bloom based on carefully blending in a [potentially blurred]
version of the original input. This version is MUCH faster, and you have to
strain to see the difference, so people with slower GPU's will prefer it.
There's a lot to play around with, and I encourage everyone using this shader to
read through the user-settings.h file to learn about the parameters. Before
loading the shader, be sure to read the next section, entitled...
////////////////////////////////////////////////////////////////////////////////
//// FREQUENTLY EXPECTED QUESTIONS: ////
////////////////////////////////////////////////////////////////////////////////
1.) WHY IS THE SHADER CRASHING WHEN I LOAD IT?!?
Do you get C6001 or C6002 errors with integrated graphics, like Intel HD 4000?
If so, please try one of the following .cgp presets:
* crt-royale-intel.cgp
* crt-royale-fake-bloom-intel.cgp
These load .cg wrappers that #define INTEGRATED_GRAPHICS_COMPATIBILITY_MODE
(also available in user-settings.h) before loading the main .cg shader files.
Integrated graphics compatibility mode will disable these three features, which
currently require more registers or instructions than Intel GPU's allow:
* PHOSPHOR_MASK_MANUALLY_RESIZE: The phosphor mask will be softer.
(This may be reenabled in a later release.)
* RUNTIME_GEOMETRY_MODE: You must change the screen geometry/curvature using
the geom_mode_static setting in user-settings.h.
* The high-quality 4x4 Gaussian resize for the bloom approximation
Using Intel-specific .cgp files is equivalent to #defining
INTEGRATED_GRAPHICS_COMPATIBILITY_MODE in your user-settings.h. Out of the box,
user-settings.h is configured for maximum configurability and compatibility with
dedicated nVidia and AMD/ATI GPU's. Compatibility mode is disabled by default
to avoid silently degrading quality for AMD/ATI and nVidia users, so Intel-
specific .cgp's are a convenient way for Intel users to play with the shader
without editing text files.
I've tested this solution on Intel HD 4000 graphics, and it should work for that
GPU at least, but please let me know if you're still having problems!
--------------------------------------------------------------------------------
2.) WHY IS EVERYTHING SO SLOW?!?:
Out of the box, this will be a problem for all but monster GPU's. The default
user-settings.h file disables any features and optimizations which might cause
compilation failure on AMD/ATI GPU's. Despite the name of the options, this is
not a problem with your card or drivers; it's a shortcoming in the Cg shader
compiler's nVidia-centric profile setups.
Uncommenting the following #define macros at the top of user-settings.h will
help performance a good deal on compatible nVidia cards:
#define DRIVERS_ALLOW_DERIVATIVES
#define DRIVERS_ALLOW_DYNAMIC_BRANCHES
#define ACCOMODATE_POSSIBLE_DYNAMIC_LOOPS
#define DRIVERS_ALLOW_TEX2DLOD
#define DRIVERS_ALLOW_TEX2DBIAS
A few of these warrant some elaboration. First, derivatives:
Derivatives allow the shader to cheaply calculate a tangent-space matrix for
correct antialiasing when curvature or overscan are used. Without them, there
are two options:
a.) Cheat, and there will be artifacts with strong cylindrical curvature
b.) Compute the correct tangent-space matrix analytically. This is used
by default, and it's controlled by this option near the bottom:
geom_force_correct_tangent_matrix = true
Dynamic branches:
Dynamic branches allow the shader to avoid performing computations that it
doesn't need (but might have, given different runtime options). Without them,
the shader has to either let the GPU evaluate every possible codepath and select
a result, or make a "best guess" ahead of time. The full phosphor bloom suffers
most from not having dynamic branches, because the shader doesn't know how big
of a blur to use until it knows your phosphor mask dot pitch...which you set at
runtime if shader parameters are enabled.
If RUNTIME_PHOSPHOR_BLOOM_SIGMA is commented out (faster), this won't matter:
The shader will just select the blur size and standard deviation suitable for
the mask_triad_size_desired_static setting in user-settings.cgp. It will be
fast, but larger triads won't blur enough, and smaller triads will blur more
than they need to. However, if RUNTIME_PHOSPHOR_BLOOM_SIGMA is enabled, the
shader will calculate an optimal standard deviation and *try* to use the right
blur size for it...but using an "if standard deviation is such and such"
condition would be prohibitively slow without dynamic branches. Instead, the
shader uses the largest and slowest blur the user lets it use (to cover the
widest range of triad sizes and standard deviations), according to these macros:
#define PHOSPHOR_BLOOM_TRIADS_LARGER_THAN_3_PIXELS
//#define PHOSPHOR_BLOOM_TRIADS_LARGER_THAN_6_PIXELS
//#define PHOSPHOR_BLOOM_TRIADS_LARGER_THAN_9_PIXELS
//#define PHOSPHOR_BLOOM_TRIADS_LARGER_THAN_12_PIXELS
The more you have uncommented, the larger the triads you can blur, but the
slower runtime sigmas will be if your GPU can't use dynamic branches. By
default, triads up to 6 pixels wide will be bloomed perfectly, and a little
beyond that (8 should be fine), but going too far beyond that will create
blocking artifacts in the blur due to an insufficient support size.
tex2Dlod:
The tex2Dlod function allows the shader to disables anisotropic filtering, which
can get confused when we're manually tiling the texture coordinates for a small
resized phosphor mask tile (it creates nasty seam artifacts). There are several
ways the shader can deal with this: The cheapest is to use tex2Dlod to tile the
output of MASK_RESIZE across the screen...and the slower alternatives either
require derivatives or force the shader to draw 2 tiles to MASK_RESIZE in each
direction, thereby reducing your maximum allowed dot pitch by half.
tex2Dbias:
According to nVidia's Cg language standard library page, tex2Dbias requires the
fp30 profile, which doesn't work on ATI/AMD cards...but you might actually have
mixed results. This can be used as a substitute for tex2Dlod at times, so it's
worth trying even on ATI.
--------------------------------------------------------------------------------
3.) WHY IS EVERYTHING STILL SO SLOW?!?:
For maximum quality and configurability out of the box, almost all shader
parameters are enabled by default (except for the disproportionately expensive
runtime subpixel offsets). Some are more expensive than others. Commenting
the following macro disables all shader parameters:
#define RUNTIME_SHADER_PARAMS_ENABLE
Commenting these macros disables selective shader parameters:
#define RUNTIME_PHOSPHOR_BLOOM_SIGMA
#define RUNTIME_ANTIALIAS_WEIGHTS
//#define RUNTIME_ANTIALIAS_SUBPIXEL_OFFSETS
#define RUNTIME_SCANLINES_HORIZ_FILTER_COLORSPACE
#define RUNTIME_GEOMETRY_TILT
#define RUNTIME_GEOMETRY_MODE
#define FORCE_RUNTIME_PHOSPHOR_MASK_MODE_TYPE_SELECT
Note that all shader parameters will still show up in your GUI list, and the
disabled ones simply won't work.
Finally, there are a lot of other options enabled by default that carry serious
performance penalties. For instance, the default antialiasing filter is a
cubic filter, because it's the most configurable, but it's also quite slow if
RUNTIME_ANTIALIAS_WEIGHTS is #defined. A lot of the static true/false options
have a significant influence, and the shader is faster if the red subpixel
offset (from which the blue one is calculated as well) is zero...even if it's
a static value, because RUNTIME_ANTIALIAS_SUBPIXEL_OFFSETS is commented out.
To avoid any confusion, I should also clarify now that subpixel offsets are
separate from scanline beam convergence offsets.
To quickly see how much performance you can get from other settings, you can
temporarily replace your user-settings.h with one of:
a.) crt-royale-settings-files/user-settings-fast-static-ati.h
b.) crt-royale-settings-files/user-settings-fast-static-nvidia.h
Then load crt-royale-fake-bloom.cgp. It should be far more playable.
--------------------------------------------------------------------------------
4.) WHY WON'T MY SHADER BLOOM MY PHOSPHORS ENOUGH?
First, see the discussion about dynamic branching above, in 1.
If you don't have dynamic branches, you can either uncomment the lines that
let the shader pessimistically use larger blurs than it's guaranteed to need
(which is slow), or...you can just use crt-royale-fake-bloom.cgp, which
doesn't have this problem. :)
--------------------------------------------------------------------------------
5.) WHY CAN'T I MAKE MY PHOSPHORS ANY BIGGER?
By default, the phosphor mask is Lanczos-resized in earlier passes to your
specified dot pitch (mask_sample_mode = 0). This gives a much sharper result
than mipmapped hardware sampling (mask_sample_mode = 1), but it can be much
slower without taking proper care: If the input mask tile (containing 8
phosphor triads by default) is large, like 512x512, and you try to resize it
to 24x24 for 3x3 pixel triads, the resizer has to take 128 samples in each
pass/direction (the max allowed) for a 3-lobe Lanczos filter. This can be
very slow, so I made the output of MASK_RESIZE very small by default: Just
1/16th of the viewport size in each direction. The exact limit scales with
your viewport size, and it *should* be reasonable, but the restrictions can
get tighter if we can't use tex2Dlod and have to fit two whole tiles (16
phosphor triads with default 8-triad tiles) into the MASK_RESIZE pass for
compatibility with anisotropic filtering (long story).
If you want bigger phosphor triads, you have two options:
a.) Set mask_sample_mode to 1 in your shader params (if enabled) or set
mask_sample_mode_static to 1 in your user-settings.h file. This will use
hardware sampling, which is softer but has no limitations.
b.) To increase the limit with manual mask-resizing (best quality), you need to
do five things:
1.) Go into your .cgp file and find the MASK_RESIZE pass (the horizontal
mask resizing pass) and the one before it (the vertical mask resizing
pass). Find the viewport-relative scales, which should say 0.0625, and
change them to 0.125 or even 0.25.
2.) Still in your .cgp file, also make sure your mask_*_texture_small
filenames point to LUT textures that are larger than your final desired
onscreen size (upsizing is not currently permitted).
3.) Go into user-cgp-constants.h and change mask_resize_viewport_scale from
0.0625 to the new value you changed it to in step 1. This is necessary,
because we can't pass that value from the .cgp file to the shader, and
the shader can't compute the viewport size (necessary) without it.
4.) Still in user-cgp-constants.h, update mask_texture_small_size and
mask_triads_per_tile appropriately if you changed your LUT texture in
step 2.
5.) Reload your .cgp file.
I REALLY wish there was an easier way to do that, but my hands are tied until
.cgp files are allowed to pass more information to .cg shaders (which would
require major updates to the cg2glsl script).
--------------------------------------------------------------------------------
6.) WHY CAN'T I MAKE MY PHOSPHORS ANY SMALLER THAN 2 PIXELS PER TRIAD?
This is controlled by mask_min_allowed_triad_size in your user-settings.h file.
Set it to 1.0 instead of 2.0 (anything lower than 1 is pointless), and you're
set. It defaults to 2.0 to make mask resizing twice as fast when dynamic
branches aren't allowed. Some people may want to be able to fade the phosphors
away entirely to get a more PVM-like scanlined image though, so change it to 1.0
for that (or get a higher-resolution display ;)).
Note: This setting should be obsolete soon. I have some ideas for more
sophisticated mask resampling that I just don't have a spare few hours to
implement yet.
--------------------------------------------------------------------------------
7.) I AM NOT RUNNING INTEGRATED GRAPHICS. WHY AM I GETTING ERRORS?
First recheck the top of your user-settings.h to make sure incompatible driver
options are commented out (disabled). If they're all disabled and you're still
having problems, you've probably found a bug. There are bound to be a number of
them with certain setting combinations, and there might even be a few individual
settings I broke more recently than I tested them. My contact information is up
top, so let me know!
--------------------------------------------------------------------------------
8.) WHY AM I GETTING BANDING IN DARK COLORS? OR, WHY WON'T MIPMAPPING WORK?
crt-royale uses features like sRGB and mipmapping, which are not available in
the latest Retroarch release (1.0.0.2) at the time of this writing.
You may get banding in dark colors if your platform or Retroarch version doesn't
support sRGB FBO's, and mask_sample_mode 1 will look awful without mipmapping.
I expect most platforms capable of running this shader at full speed will
support sRGB FBO's, but if yours doesn't, please let me know, and I'll include
a note about it.
Alternately, setting levels_autodim_temp too low will cause precision loss and
banding.
--------------------------------------------------------------------------------
9.) HOW DO I SET GEOMETRY/CURVATURE/ETC.?
If RUNTIME_SHADER_PARAMS_ENABLE and RUNTIME_GEOMETRY_MODE are both #defined (not
commented out) in user-settings.cgp, you can find these options in your shader
parameters (in Retroarch's RGUI for instance) under e.g. geom_mode. Otherwise,
you can set the corresponding e.g. geom_mode_static options in user-settings.h.
--------------------------------------------------------------------------------
10.) WHY DON'T MY SHADER PARAMETERS STICK?
This is a bit confusing, at least in the version of Retroarch I'm using.
In the Shader Options menu, Parameters (Current) controls what's on your screen
right now, whereas Parameters (RGUI) seems to control what gets saved to a
shader preset (in your base shaders directory) with Save As Shader Preset.
--------------------------------------------------------------------------------
11.) WHY DID YOU SLOW THE SHADER DOWN WITH ALL OF THESE FEATURES I DON'T WANT?
WHY DIDN'T YOU MAKE THE DEFAULTS MORE TO MY LIKING?
The default settings tend to best match flat ~13" slot mask TV's with sharp
scanlines. Real CRT's however vary a lot in their characteristics (and many are
softer in more ways than one), so it's impossible to make the default settings
look like everyone's favorite CRT. Moreover, it's impossible to decide which
of the slower features and options are superfluous:
Some people love curvature, and some people hate it. Some people love
scanlines, and some people hate them. Some people love phosphors, and some
people hate them. Some people love interlacing support, and some people hate
it. Some people love sharpness, and some people hate it. Some people love
convergence error, and some people hate it. The one thing you hate the most is
probably someone else's most critical feature. This is why there are so many
options, why the shader is so complicated, and why it's impossible to please
everyone out of the box...unfortunately.
That said, if you spend some time tweaking the settings, you're bound to get a
picture you like. Once you've made up your mind, you can save the settings to
a user-settings.h file and disable shader parameters and other slow options to
get the kind of performance you want.
--------------------------------------------------------------------------------
12.) WHY DIDN'T YOU INCLUDE A SHADER PRESET WITH NTSC SUPPORT? WHY DIDN'T YOU
INCLUDE MORE CANNED PRESETS WITH DIFFERENT OPTIONS? WHY CAN'T I SELECT
FROM ONE OF SEVERAL USER SETTINGS FILES WITHOUT MANUAL FILE RENAMING?
I do plan on adding a version that uses the NTSC shader for the first two
passes, but it will take a bit of work, because there are several NTSC shader
versions as it is. It's easy enough to combine the HALATION_BLUR passes into a
one-pass blur from blurs/blur9x9fast.cg, but I'm not sure yet just how much
modification the NTSC shader passes themselves might need for best results.
I originally wanted NTSC support to be included out-of-the-box, but I'd also
like to release the shader ASAP, so it'll have to wait.
As for other canned presets, that's a little more complicated: I DO intend on
creating more canned presets, but the combinatorial explosion of major codepath
options in this shader is too overwhelming to be as exhaustive as I'd like.
When I get the time, I'll add what I can to make this more user-friendly.
In the meantime, I'll start adding a few different default versions of the
user settings file and put them in a subdirectory for people to manually
place in the main directory and rename to "user-settings.h."
However, the libretro Cg shader specification (and the Cg to GLSL compiler) does
not currently allow .cgp files to pass any static settings to the source files.
This presents a huge problem, because it means that in order to create a new
preset with different options, I also have to create duplicate files for EVERY
single .cg pass for every permutation, not just the .cgp. I plan on creating
a number of skeleton wrapper .cg files in a subdirectory (which set a few
options and then include the main .cg file for the pass), but it'll be a while
yet. In the meantime, I'd rather let people play with what's already done than
keep it hidden on my hard drive.
--------------------------------------------------------------------------------
13.) WHY DO SO MANY VALUES IN USER_SETTINGS.H HAVE A _STATIC SUFFIX?
The "_static" suffix is there to prevent naming conflicts with runtime shader
parameters: The shader usually uses a version without the suffix, which is
assigned either the value of the "_static" version or the runtime shader
parameter version. If a value in uset-settings.h doesn't have a "_static"
suffix, it's usually because it's a static compile-time option only, with no
corresponding runtime version. Basically, you can ignore the suffix. :)
--------------------------------------------------------------------------------
14.) ARE THERE ANY BROKEN SETTINGS I SHOULD BE AWARE OF?
WHAT IF I WANT TO CHANGE SETTINGS IN THE .CGP FILE?
As far as I know, all of the options in user-settings.h and the runtime shader
parameters are pretty robust, with a few caveats:
* As noted above, there are some tradeoffs between runtime and compile-time
options. If runtime blur sigmas are disabled for instance, the phosphor
bloom (and to a lesser extent, the fake bloom) may not blur the right amount.
* If you set your aspect ratio incorrectly, and mask_specify_num_triads == 1.0
(i.e. true, as opposed to 0.0, which is false), the shader will misinterpret
the number of triads you want by the same proportion.
* Disabled shader parameters will do nothing, including either:
a.) mask_triad_size_desired
b.) mask_num_triads_desired,
depending on the value of mask_specify_num_triads.
There is a broken and unimplemented option in derived-settings-and-constants.h,
but users shouldn't need to mess around in there anyway. (It's related to the
more efficient phosphor mask resampling I want to implement.)
However, the .cgp files are another story: They are pretty brittle, especially
when it comes to their interaction with user-cgp-constants.h. Be aware that the
shader passes rely on scale types and sizes in your .cgp file being exactly what
they expect. Do not change any scale types from the defaults, or you'll get
artifacts under certain conditions. You can change the BLOOM_APPROX and
MASK_RESIZE scale values (not scale types), but you must update the associated
constant in user-cgp-constants.h to let the .cg shader files know about it, and
the implications may reach farther than you expect. Similarly, if you plan on
changing an LUT texture, make sure you update the associated constants in
user-cgp-constants.h. In short, if you plan on changing anything in a .cgp
file, you'll want to read it thoroughly first, especially the "IMPORTANT"
section at the top.
--------------------------------------------------------------------------------
15.) WHAT ARE THE MOST COMMON DOT PITCHES FOR CRT TELEVISIONS?
WHAT KIND OF RESOLUTION WOULD I NEED FOR A REAL SHADOW MASK?
The most demanding CRT we're ever likely to emulate is a Sony PVM-20M4U:
Width: 450mm
Aperture Grille Pitch: 0.31mm
Triads in 4:3 frame: 1451, assuming little to no overscan
For 3-pixel triads, we would need about 6k UHD resolution. A BVM-20F1U has
similar requirements.
However, common slot masks are far more similar to the kind of image this shader
will produce at 900p, 1080p, 1200p, and 1440p:
1.) A typical 13" diagonal CRT might have a 0.60mm slot pitch, for a total of
440.26666666666665 or so phosphor triads horizontally.
2.) A typical 19" diagonal CRT might have a 0.75mm slot pitch, for a total of
514.7733333333333 or so phosphor triads horizontally.
3.) According to http://repairfaq.ece.drexel.edu/REPAIR/F_crtfaq.html, a
typical 25" diagonal CRT might have a 0.9mm slot pitch, for a total of
564.4444444444445 or so phosphor triads horizontally.
4.) A 21" Samsung SMC210N CCTV monitor (450 TV lines) has a 0.7mm stripe
pitch, for a total of 609.6 or so phosphor triads horizontally.
The included EDP shadow mask starts looking very good with ~6-pixel triads, so
it may take nearly 4k resolution to make it a particularly compelling option.
However, it's possible to make smaller shadow masks on a pixel-by-pixel basis
and tile them at a 1:1 ratio (mask_sample_mode = 2). I may include a mask like
this in a future update.
--------------------------------------------------------------------------------
16.) IS THIS PHOSPHOR BLOOM REALISTIC?
Probably not:
Realistically, the "phosphor bloom" blurs bright phosphors significantly more
than your eyes would bloom the brighter phosphors on a real CRT. This extra
blurring however is necessary to distribute enough brightness to nearby pixels
that we can amplify the overall brightness to that of the original source after
applying the phosphor mask. If you're interested, there are more comments on
the subject at the top of the fragment shader in crt-royale-bloom-approx.cg.
On the subject of the phosphor bloom: I intended to include some exposition
about the math behind the brightpass calculation (and the much more complex
and thorough calculation I originally used to blur the minimal amount necessary,
which turned out to be inferior in practice), but that document isn't release-
ready at the moment. Sorry Hyllian. ;)
--------------------------------------------------------------------------------
17.) SO WHAT DO YOU PLAN ON ADDING IN THE FUTURE?
I'd like to add these relatively soon:
1.) A combined ntsc-crt-royale.cgp and ntsc-crt-royale-fake-bloom.cgp.
2.) More presets, especially if maister or squarepusher find a way to make the
Cg to GLSL compiler process .cgp files (which will allows .cgp's to pass
arbitrary #defines to the .cg shader passes).
3.) More efficient and flexible phosphor mask resampling. Hopefully, this will
make it possible to manually resize the mask on Intel HD Graphics as well.
4.) Make it more easy and convenient to use and experiment with mask_sample_mode
2 (direct 1:1 tiling of an input texture) by using a separate LUT texture
with its own parameters in user-cgp-constants.h, etc. I haven't done this
yet because it requires yet another texture sample that could hurt other
codepaths, and I'm waiting until I have time to optimize it.
5.) Refine the runtime shader parameters: Some of them are probably too fine-
grained and slow to change.
Maybe's:
1.) I've had trouble getting LUT's from subdirectories to work consistently
across platforms, but I'd like to get around that and include more mask
textures I've made.
2.) If you're using spherical curvature with a small radius, the edges of the
sphere are blocky due to the pixel discards being done in 2x2 fragment
blocks. I'd like to fix this if it can be done without a performance hit.
3.) I have some ideas for procedural mask generation with a fast, closed-form
low-pass filter, but I don't know if I'll ever get around to it.

Thank you squarepusher and maister, for hammering out the shader framework that
made this possible and being so receptive to my feedback for Retroarch and the
libretro Cg shader spec. Thank you especially maister, for designing the sRGB
support with me and implementing all the code for both sRGB FBO's and mipmapped
FBO's in less time than it took me to add mipmapped LUT's alone!
I want to thank xythen and DOLLS for inspiring me with their early efforts:
http://board.byuu.org/viewtopic.php?f=10&t=147
http://board.byuu.org/viewtopic.php?p=3820#p3834
I've never spoken with them, but I never would have thought to make this shader
if xythen hadn't gotten the ball rolling, or if DOLLS hadn't made his point
about just how far CRT emulation could go with his phosphor mask prototypes,
convergence error images, and barrel distortion code.
I also want to thank hunterk for his excellent blog, especially this post:
http://filthypants.blogspot.com/2011/05/
more-emulator-pixel-shaders-crt-updated.html
Along with caligari's work, his PhosphorLUT shader provoked me to experiment
with game-style bloom as a way to reconcile shadow masks with full brightness.
Along with Pulp Fiction, he also gets credit for helping me name this shader. :D
Thank you Hyllian for your enthusiasm: It kept me focused on actually releasing
this shader instead of refining it in perpetuity!
Finally, I want to thank cgwg for everything he has done for CRT emulation:
He was the first to consider the effects of halation, and (in addition to
caligari?) he did the most research on the Gaussian properties of scanline
electron beams. His forum posts and links to academic research were very
helpful, and so were the few PM's we exchanged many months ago: I originally
meant to wet my feet by extending his shader with cylindrical curvature before
writing my own. I never managed to understand his curvature code (due to all of
the different algebraic/trigonometric stages being rolled into one), and I gave
up and started from scratch, but talking with him helped me piece together how
his spherical uv<=>xyz mapping worked mathematically. My own is subtly
different, but not on purpose. ;) A lot of the user parameters for geometry
were inspired by his own (including Euler angle tilt and a "view distance" for
controlling the field of view with a simplified near-plane). Last but not
least, my border dimming code was based more directly off of his: I did what I
could to write a fresh implementation of his algorithm with new features, but
the line between code and algorithm is pretty thin in that function, and it's
a testament to him coming up with such an elegant solution.

// 4.) dxdy should contain the uv pixel spacing:

// 5.) texture_size == SRC.texture_size

// 7.) tex_uv_to_pixel_scale == IN.output_size *

// 1.) Instead of writing an absolute size to user-cgp-constants.h, we'd
// write a viewport scale. That number could be used to directly scale
// the viewport-resolution bloom sigma and/or triad size to a smaller
// scale. This way, we could calculate an optimal dynamic sigma no
// matter how the dot pitch is specified.
// CONS:
// 1.) Texel smearing would be much worse at small viewport sizes, but
// performance would be much worse at large viewport sizes, so there
// would be no easy way to calculate a decent scale.
// 2.) Worse, we could no longer get away with using a constant-size blur!
// Instead, we'd have to face all the same difficulties as the real
// phosphor bloom, which requires static #ifdefs to decide the blur
// size based on the expected triad size...a dynamic value.
// 3.) Like the phosphor bloom, we'd have less control over making the blur
// size correct for an optical blur. That said, we likely overblur (to
// maintain brightness) more than the eye would do by itself: 20/20
// human vision distinguishes ~1 arc minute, or 1/60 of a degree. The
// highest viewing angle recommendation I know of is THX's 40.04 degree
// recommendation, at which 20/20 vision can distinguish about 2402.4
// lines. Assuming the "TV lines" definition, that means 1201.2
// distinct light lines and 1201.2 distinct dark lines can be told
// apart, i.e. 1201.2 pairs of lines. This would correspond to 1201.2
// pairs of alternating lit/unlit phosphors, so 2402.4 phosphors total
// (if they're alternately lit). That's a max of 800.8 triads. Using
// a more popular 30 degree viewing angle recommendation, 20/20 vision
// can distinguish 1800 lines, or 600 triads of alternately lit
// phosphors. In contrast, we currently blur phosphors all the way
// down to 341.3 triads to ensure full brightness.
