From now on the official +ChangeLog file will be generated automagically from CVS. + +So, please do not edit this file. + +---------------------------------------------------------------------------- + +:::::::::::::: +ChangeLog +:::::::::::::: +Version 3.1 + o New homepage at http://www.gnu.org + Speedups: + o The internal loop now uses integer comparisons on x86 (about 10% + speedup) + o Better timming + o Cleverer and faster solid guessing algorithm + o Faster resolution reduction loops (more cache and SMP friendly) + o Faster copying loops (lower register pressure because of new table + layout) + o New string inlines for x86 that does aligning of memory acceses + o I've made some patches to gcc-2.95 to improve XaoS code + o Assembly loops for moving data + (overall XaoS is more than twice the speed of version 3.0) + New features + o New antialiasing filter + o New drivers: + GGI + DGA + Win32 + dX-window + dX-fullscreen + BeOS + DirectWindow + DirectScreen + o Improved tutorials: + o New tutorial "math behind fractals" + o First chapter of tutorial "an introduction to fractals" has been + split into the introduction part and part about the Mandelbrot set + o Improved first chapter + o Added line graphics into many tutorials + o Spanish message catalog contributed by Cesar Perez + o Added (color) command to specify color of text + o Rendering sequences of images from animation files + o New wrapper around I/O routines alowing XaoS to read arbitary streams + like string etc. + o New library for handling menus added. I think it is big step towards + a nice user interface, since all keybindings and menus will be + independent at UI, so the ugly interface now will be just simple code + calling this library. + o Added simple dialog description structure... + o Added library with simple graphics primitives (line, rectangle, + text) + o Palette extended to allow few preallocated color cells for UI and + such. + o Timer library now handles current group changes nicely, + also supports time emulation used by emulating constant framerate + good for saving animations + o Palette creator now accepts zero for maximal palette size + o Lots of play functions made generic and integrated into user + interface (user now should specify palette seed or reset state + of XaoS into "factory defaults") + o Menus, dialog, command line options, hotkeys and animation replay + code now use same function registry. So there are lots of new command + line parameters, file format commands etc... + + Some command line parameters also changed their name (like -load -> + -loadpos) so please modify your scripts... + o Added xshl (XaoS simple hypertext langage) library + o Motion blur now handles changes of filter configuration in better + way + o Added some other fractal examples into first chapter + o Behave better when btrace or interruptible calculation interrupted + o Documentation split into Hacker's and User's guide, so we don't need + to distribute hacker documentation in the source distributions and + users don't need to print this part. + o Timer library now supports Win32 high precision timer + o Support for backslash path convention under DOS and Windows + o Accept both \n lines and \n\r lines + o Internationalization (i18n) support added for menus + o New fractal types: newton^4, barsnley2 and magnet2 + UI changes: + o Menus are now displayed nicely + o New nice dialogs. XaoS is now mostly user friendly :) + o Native UI wrappers for BeOS and Windows + o Undo and redo, cut and past available at many systems + o Main menu is now available at 'enter' key. + o Better arrow keys handling + o Formula changing now resets perturbation too + o New context sensitive help. + Now uses xshl (XaoS simple hypertext language), so you + might do hyperlinks, links to tutorials and basic formating of text + o Bailout may be set + o Logarithmic zoom ratio also displayed in ministatus + Driver API changes + o Drivers now sends special keys as KEY_UP etc... + o Parameter parsing library cleaned. It now don't prints driver's + name automatically in help text. Use HELP line. (see ui_template.c) + o Removed TRUECOLORMI, HICOLOR and REALCOLOR image types. + There is now just TRUECOLOR16, TRUECOLOR24 and TRUECOLOR. + to set where red, green and blue channels lie use new redmask, + greenmask and bluemask fields in driver's structure + o Similar changes in the S* configure defines + o Removed unused functions: driveropt (now should be done by menus) + clrscr (now XaoS does in the buffer) + o Added new flag RESIZE_COMMAND + (if ui should add an '=' resize function to menu - should be enabled + in the most fullscreen drivers, which don't do resizing dialog + using menus, but using getsize call - like SVGAlib etc.) + windowed drivers should disable this + o Removed help entry (add this text into xaos.hlp file with same + keyword as your driver's short name) + UI-helper changes: + o It is now based on a menuing system... controls are almost the same, + but internally implementation is different. Only visible changes I + know about are that double 'q' for quit doesn't work anymore, and 's' + menu is now like the file menu in many programs, so it contains quit and + other functions. + o window handling + o New message and error handling code + o Displays texts directly to output buffer instead of asking + ui interface + o Improved passfunc + o Support for constant framerate emulation + Fixes: + o Support for libpng 1.0.x and 1.1.x + o Fixed email addresses in ANNOUNCE + o Fixed nasty bug in timer library - it caused great memory + corruption.. + o Fixed crash in palette filter + o Fixed some memory leaks + o Color cycling don't overwrite filter's palette anymore + o Fixed memory leak in blur.c + o Enabled forgotten optimizations for bpp==1 + o Removed IMO unusable command (calculate) + o Fixed memory leak in error handling in play.c + o Check for inconzestient configuration in ui_helper.c + o play now accepts empty files + o cycling speed is saved correctly + o Filters are now saved in right order, filters that depends + at master are initialized first. + o No crash when user tries to set letterspersec to 0, + it's not allowed now + o Fractal type magnet has been modified + Cleanups: + o Removed lots of ui code and moved to menu.c + o Removed old and obsolete functions ui_message, ui_tbreak, ui_menu + ui_message2 renamed to ui_message + o Removed ui_tbreak calls from x11 driver + o Removed curses driver - it is obsoleted by aa driver now + o Structure timer moved to timerlib... + o Removed ui_getcontext, since it is old and ugly hack to give + better control to driver not recommended at all... + o Removed special driver menu code and integrated into XaoS menuing + system + o Removed some code duplication in uinew + o Removed old keyboard buffer code in uinew.c + o Assertions are now disabled in zoom.c + o ui and ui-helper split into separate directories + o uinew renamed back to ui.

Stallman agreed with adding XaoS into GNU project + Fixes: + o XaoS is now sticky bit save when svgadriver enabled + o Fixed crash in resizing in stereogram mode + o Fixed crash in stereogram mode+different scanline/width + o Fixed crash with dealing NaN sizes + o Fixed small bug in mkrealloctable + o Fixed ctrl87.c to do not make compilation problems anymore + (was renamed to i386.c :) but also some register conflicts fixed. + o Fixed memory owerflowing in julia code + o Removed GIF code due to patent problems + o Timer library and ui code now handles better low resolution timers + Also measuring of time for status line changed. So gives bit + different results now :) (lower but more exact) + o Fixed few minnor bugs in solid guessing. Now it should be + more effective. But who knows... + o -incoloring now works + Major code reorganization. + o New palette functions supports + x truecolor, truecolor24, hicolor and maxcolor handling + x allocation/set palette scheme + o New nice image structure that suppotrs: + x truecolor, truecolor24, hicolor, maxcolor, and 256 colors + x nonstandard order of lines (like one in windoze etc..) + x double buffering + x palette functions + o New partially object oriented filter sistem + x allows elegant way to add effects like stereogram generation + x makes possible to reduce resolution after stereogram etc.. + x combination of various calculation algorithms is now + possible in elegant way + x makes source code much cleaner and extensible + o New user interface helper library + x makes easy to add new user interfaces or use as + a part of some other program + x implemented in cleaner way than old ugly-interface + x hides XaoS's internals and provides easy to understand + set of functions for users of XaoS engine. + o XaoS now uses center/range possitioning instead of + left top/right bottom becase: + x it is better human readable (you can see zoom easily) + x it is more exact (small difference do not fall to zero + as soon as in normal system) + x it is easier to handle in rotation (you can do still + same operations - zooms, movements like in unrotated. + x better fits operation permited in(zooming view/moving) + x I expect will look better in save files + x simplified many operations performed on it. + o As the side effect: + x old ugly interface code is a bit obsolette. Requires + small changes into drivers + x no more large zoom_context. Context is now divided into + many parts. So many structures should be used by other + parts of XaoS separately. + x zoom.[ch] splitted into fractal routines and zooming + engine. This makes easier add ingnew zooming/calculation + methods (like on in fractos, boundary detection...) + x most of siggnificant data structures are copied into fixed + memory locations before start of calculation. I expect it + will speed up accesing its field because complex + traveling throught pointers will be avoided and reduces + number of parameters passed to calculation functions. + At the other hand it should bring many problems in + multithreading. In calculating one image at many procesors + should be OK. Since these structures are same. Calculating + of multiple images at time should be real problem. But why + not use multitasking? or some hack with redefinig this + structures back into pointers should be possible in this + cases. + x less multiplyings but more memory accesses in + calcline/column should speedup on pentiums with fast + cache. + x autopilot now should work at many contexts at time + x better implementation of fill + x many new bugs but few old fixed + x ugly interface code was greatly simplified since everything + interesting went into ui_helper + x resizing and such stuff is now much simplier + x palette rotation implemented in cleaner way. Now does + not require changes into drivers. Uses new setpalette + driver function. I can not imagine hardware, where + setpalette is imposible but rotation possible. + x timer library now passes userdata to handlers - required + for implementation of rotatepalette + x palette rotatin in truecolor modes is not possible anymore + (since xaos is not internally 8bit) + Cleanups: + o New macro system for formulas that allows easy manipulation + with calculation loops. But looks ugly. Is that cleanup? + o Julia code is now automatically generated for formulas.. + o Directory structure, + XaoS divided into several libs (engine,ui,util,drivers) + o Simplier configuration headers + o timerlib:wait mechanizm has obsoletted by much better slowdown + mechanizm + Speedups: + o Boundary detection for new images + o I've browsed mkrealloctable and removed few unnecesary + ifs. Maybe it speeded up.. + o MAGICAL VALUE OF 100 FPS IS GONE!!!! Now you can see 120 FPS + on pentium :) + New completly fixedpoint mkrealloctable performs very well! + (isn't that cool idea? just simple precalclate everything into + fixedpoint that depends on the zoom and do rest in + integers ? :))) I am so silly coder! now XaoS usually does + not fall under 7fps on my 486 so it works in acceprable + performance. maybe we should add logo "Ready for 486!(tm)" + :) (and whats about fixed point calculation loops? :) + Fixedpoint brought many advantages - precalculated pow + tables, no owerflowing/NaN/precisity problems, many + variables changed to constants(since distance between + lines is statically 512) and much more :) + Now we should start thinking about deepzoom feature + since most of XaoS is already resolution independent. + New mkrealloctable is approx twice as fast on pentium + (tests on 486 should be interesting) + o Dynamical resolution lowering now performs much better + (Should help especially on 486) + o Better dynamical resolution timeout choice - keeps + higher framerate during zooming but lowers after + zooming stops. + o At 386 uses uptimized versions of memset and memcpy + o A bit faster julia calculation loop + o Autopilot code is now simplier, faster, has better out of + range and lowqualitty detection and seems to have better + results + o Macro system in calculation loop caused instant speedup. Why? + o New new possition caluclation algorithm. Seems to be a bit faster + and produces better results + o Random dot generator now reduces resolution to 1/4, + because brain is unable to decode image inormations at + normal resolution. :) + o New uncompressed loops - one iteration for mandelbrot is + just about 14 instructions (was 23) + o Periodicity checking + Fabrice Premel <premelfa@etu.utc.fr> + o Another 1/8 speedup caused by forcing register allocation + (i386 only) + o Malloc/free is now called less often (once per frame) + New features: + o BeOs driver. + Jens Kilian <jjk@acm.org> + o Truecolor(24/32-little and big edian), Hicolor, Realcolor, Fixedcolor + and monochrome support + o Interlace filter that instantly makes your computer + twice as fast! + o Motion blur filter + o Dithering filter + o Julia preview for all formula types + o Image rotation + o New AA-lib driver that does high qualitty text mode rendering + see AA project homepage at http://www.ta.jcu.cz/aa + o Two edge detection filters + o Palette emulation filter + o Emboss filter + o SMP support using threads + o Two new palette generation algorithms + o Changed default window size to 480x360 because I hope that XaoS + is now fast enought to work in resonable speed at this resolution + o Animated tutorials: + Introduction to fractal + features overview + whats new + o New outcoloring modes: + o Potential + o Another colorfull decomposition + o Smooth (for truecolor/truecolor24/hicolor/realcolor displays) + o New incoloring modes + o decomposition-like + o real/imag + o Save images into PNG format. Problem is that now XaoS + requires zlib and pnglib that should bring problems to + users compiling XaoS at UNIX workstations. I personally + dislike writing of image saving code. Please if you have + some, or you want to write code, that don't require these + libraries, let me know. + o Saving of possition. + o Documentation is now in texinfo format. Describes some XaoS + internals + o Timer library: + x handler should remove its timer when activated + x New slowdown, stop and resume functions + x Runtime switching between allegro compatible mode and + uclock mode + o Configure script now does simple autodetection for long + double - enables it just at intel compatible platforms, since + it is sure, that it works well there. Let me know about other + platforms with fast working long double + o New file README.compilers, that discuss optimizing + switches/problems with various compilers/platforms. + UI Changes + o added -delay option as suggested by Johan Hagman + o added -maxframerate option that is similiar to -delay + o added -letterspersec option to changes subtitles speed + o added -threads command line option + o added menu for saving + o added .XaoSrc file + o new -play, -load, -letterspersec options + o major rewrite + o 'E' now handle filters (not just stereogram) + o 'O' now handler image rOtation + o 'B' for perbutation + o Help should be paged using up and down arrow + o 'S' now have menu for various saving options + also during animation recording 'S' menu contains some special + commands like clearing of sceeen or text ourput primitives + o 'V' now handles "various stuff menu" - menu with not so often used + thinks. So 'K' 'G' 'T' and 'D' are free again :) + o Palette rotation renamed to color cycling to reduce confusin + with image rotation. So it is activated by 'Y' now. + o Julia mode is not disabled after keypress. + o Configuration file + o Drivers now provides information about textwidth and function + to clear screen + o New timming code allowing better replay at different + resolution/computer + o dynamic time for dynamic resolution (nice feature :) now works + better on architectures with unexact timming(like dos with + old timming routines) + PLAN9 Changes + o Updated driver to work better with new user interface code, + some cleanups + o -nopalette switch is now handled better - XaoS enables dithering + so output is almost identical to user palette mode. Just it is a bit + slower and requires more memory. + o Removed mkfile, since it became obsolette because of source + code reorganization. I am still unable to write mkfiles since + some required files seems to be missing in "demo" installation + so back to mk script :( + o Suport for 1bpp displays + SVGA Changes + o Supports truecolor, missordered truecolor, truecolor24, hicolor + and realcolor modes + o Some hacks in order to make thread stuff working + X11 Changes + o support for fullscreen mode so XaoS can act as screensaver. + Johan Hagman <Johan.Hagman@mailbox.swipnet.se> + o works on alphas and other 64bit architectures in + hicolor/truecolor mode Alexander V. Lukyanov + <lav@video.yars.free.net> + (this change is now obsolette since hicolor/truecolor is in + the main engine now) + o removed some XFlush calls so XaoS is now MUCH faster, but should + make problems at old servers. Use -sync + o Fixed resize and keysym crash + o Supports truecolor, missordered truecolor, hicolor, realcolor and fixedcolor + o Uses private colormap as default since shared colormap looks + too ugly. (note that shared colormap scheme is still supported, + but features are bit limited) + o added -display switch + o Now have normal, wait and replay mouse + o Handles keyboard better. + o Reduced memory usage in X11 modes + o Support for black and white modes + DOS Changes + o supports new allegro(2.2)-better dialog, portability, higher + resolutions + o fixed timming - now it works in much higher framerate(not + limited to 18.2 and even to 3.64 in dynamic resolution) + o new -i_love_bill for windows friendly mode + o Now compiles with lfn enabled + o does not work under linux dosemulator anymore + (dosemulator guys fixed the problem, so it works again :) + o Updated for work-in-progress allegro(www.talula.demon.co.uk) + now supports truecolor, hicolor and realcolor, also driver is + much simplier since custom dialog code is not required anymore. + o Have new lovely wait cursor +------------------------------------------------------------------------------- +Version 2.2 + Fixes: + o bug in palette changing code + o more detections for various curses versions + o small well hidden bug in reallocation algorithm discovered. + o removed passing in registers to avoid compiler bug + o now allows unzoom greater than MAX_INT again + o symetry handling works for deeper unzooms too. + o more test for owerflowing/underflowing of resolution. + so now produces garbage but does not crash(feature?) + o more exact zooming/unzooming + o better framerate handling + o fixes for pgcc - do not generate faults.. + Cleanups: + o char * -> unsigned char * + o mkrealloctable + o some optimizations for pipelining + o cleaned code to compile with -pedantic -traditional -Wall + o ugly interface-better menu code, drawing fractal etc.. + o all timing code changed to use timer library + o approximation algorithm + o functions called maximally once per frame are not inlined + anymore + o created few directories for documentation etc.. + o Minor changes in color indexing + o palette changing code + o rewrote solid guessing + o some variables in drivers structure changed to flags + Speedups: + o symetry handling code in mkrealloc table optimized a bit. + now is faster,shorter and does better job. :) + o non x/y symetries disabled because they slowes down for now.. + o approximation algorithm optimized-lots of memory accesses + avoided-great speedup.. + now performs much better(16fps -> 18 on 486) + also small hidden bug discovered, pricing redesigned a bit + and loops simplified-divided into more loops + function is now longer. + Also taken special care to minimize number of PRICE calls + mkrealloc tables is not main problem anymore.
