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.

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 + 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. + diff --git a/crt/shaders/crt-royale/THANKS.TXT b/crt/shaders/crt-royale/THANKS.TXT new file mode 100644 index 00000000..4966f0e7 --- /dev/null +++ b/crt/shaders/crt-royale/THANKS.TXT @@ -0,0 +1,43 @@ +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.

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. + +TroggleMonkey diff --git a/crt/shaders/crt-royale/src/bind-shader-params.h b/crt/shaders/crt-royale/src/bind-shader-params.h index 5a1792e9..08555da7 100644 --- a/crt/shaders/crt-royale/src/bind-shader-params.h +++ b/crt/shaders/crt-royale/src/bind-shader-params.h @@ -27,7 +27,7 @@ // Override some parameters for gamma-management.h and tex2Dantialias.h: #define OVERRIDE_DEVICE_GAMMA -const float gba_gamma = 3.5; // Irrelevant but necessary to define. +static const float gba_gamma = 3.5; // Irrelevant but necessary to define. #define ANTIALIAS_OVERRIDE_BASICS #define ANTIALIAS_OVERRIDE_PARAMETERS @@ -38,8 +38,9 @@ const float gba_gamma = 3.5; // Irrelevant but necessary to define. #endif // Bind option names to shader parameter uniforms or static constants. +#ifdef HARDCODE_SETTINGS #ifdef PARAMETER_UNIFORM -/* uniform float crt_gamma; + uniform float crt_gamma; uniform float lcd_gamma; uniform float levels_contrast; uniform float halation_weight; @@ -57,8 +58,8 @@ const float gba_gamma = 3.5; // Irrelevant but necessary to define. uniform float beam_horiz_filter; uniform float beam_horiz_linear_rgb_weight; #else - const float beam_horiz_filter = clamp(beam_horiz_filter_static, 0.0, 2.0); - const float beam_horiz_linear_rgb_weight = clamp(beam_horiz_linear_rgb_weight_static, 0.0, 1.0); + static const float beam_horiz_filter = clamp(beam_horiz_filter_static, 0.0, 2.0); + static const float beam_horiz_linear_rgb_weight = clamp(beam_horiz_linear_rgb_weight_static, 0.0, 1.0); #endif uniform float convergence_offset_x_r; uniform float convergence_offset_x_g; @@ -69,7 +70,7 @@ const float gba_gamma = 3.5; // Irrelevant but necessary to define. #ifdef RUNTIME_PHOSPHOR_MASK_MODE_TYPE_SELECT uniform float mask_type; #else - const float mask_type = clamp(mask_type_static, 0.0, 2.0); + static const float mask_type = clamp(mask_type_static, 0.0, 2.0); #endif uniform float mask_sample_mode_desired; uniform float mask_specify_num_triads; @@ -81,8 +82,8 @@ const float gba_gamma = 3.5; // Irrelevant but necessary to define. uniform float aa_cubic_c; uniform float aa_gauss_sigma; #else - const float aa_cubic_c = aa_cubic_c_static; // Clamp to [0, 4]?

OVERRIDE_FINAL_GAMMA: The user must first define: +// static const float input_gamma +// static const float intermediate_gamma +// static const float output_gamma +// (intermediate_gamma is for GAMMA_ENCODE_EVERY_FBO.) +// 4.) OVERRIDE_ALPHA_ASSUMPTIONS: The user must first define: +// static const bool assume_opaque_alpha +// The gamma constant overrides must be used in every pass or none, +// and OVERRIDE_FINAL_GAMMA bypasses all of the SIMULATE* macros. +// OVERRIDE_ALPHA_ASSUMPTIONS may be set on a per-pass basis. +// Usage: After setting macros appropriately, ignore gamma correction and +// replace all tex*D*() calls with equivalent gamma-aware +// tex*D*_linearize calls, except: +// 1.) When you read an LUT, use regular tex*D or a gamma-specified +// function, depending on its gamma encoding: +// tex*D*_linearize_gamma (takes a runtime gamma parameter) +// 2.) If you must read pass0's original input in a later pass, use +// tex2D_linearize_ntsc_gamma. If you want to read pass0's +// input with gamma-corrected bilinear filtering, consider +// creating a first linearizing pass and reading from the input +// of pass1 later. +// Then, return encode_output(color) from every fragment shader. +// Finally, use the global gamma_aware_bilinear boolean if you want +// to statically branch based on whether bilinear filtering is +// gamma-correct or not (e.g. for placing Gaussian blur samples). +// +// Detailed Policy: +// tex*D*_linearize() functions enforce a consistent gamma-management policy +// based on the FIRST_PASS and GAMMA_ENCODE_EVERY_FBO settings. They assume +// their input texture has the same encoding characteristics as the input for +// the current pass (which doesn't apply to the exceptions listed above). +// Similarly, encode_output() enforces a policy based on the LAST_PASS and +// GAMMA_ENCODE_EVERY_FBO settings. Together, they result in one of the +// following two pipelines. +// Typical pipeline with intermediate sRGB framebuffers: +// linear_color = pow(pass0_encoded_color, input_gamma); +// intermediate_output = linear_color; // Automatic sRGB encoding +// linear_color = intermediate_output; // Automatic sRGB decoding +// final_output = pow(intermediate_output, 1.0/output_gamma); +// Typical pipeline without intermediate sRGB framebuffers: +// linear_color = pow(pass0_encoded_color, input_gamma); +// intermediate_output = pow(linear_color, 1.0/intermediate_gamma); +// linear_color = pow(intermediate_output, intermediate_gamma); +// final_output = pow(intermediate_output, 1.0/output_gamma); +// Using GAMMA_ENCODE_EVERY_FBO is much slower, but it's provided as a way to +// easily get gamma-correctness without banding on devices where sRGB isn't +// supported. +// +// Use This Header to Maximize Code Reuse: +// The purpose of this header is to provide a consistent interface for texture +// reads and output gamma-encoding that localizes and abstracts away all the +// annoying details. This greatly reduces the amount of code in each shader +// pass that depends on the pass number in the .cgp preset or whether sRGB +// FBO's are being used: You can trivially change the gamma behavior of your +// whole pass by commenting or uncommenting 1-3 #defines. To reuse the same +// code in your first, Nth, and last passes, you can even put it all in another +// header file and #include it from skeleton .cg files that #define the +// appropriate pass-specific settings. +// +// Rationale for Using Three Macros: +// This file uses GAMMA_ENCODE_EVERY_FBO instead of an opposite macro like +// SRGB_PIPELINE to ensure sRGB is assumed by default, which hopefully imposes +// a lower maintenance burden on each pass.
