Usefull when there's a lack of memory. 3°) FracPro runs under NTSC. 4°) Awfull bug removed. 5°) CycleToMenu compatible. @endnode @node Copyright "Copyright" ***************************************************************************** ***************************************************************************** FracPro is an Allenbrand Brice Production for RINGARD' PRODUCTION.

If you use FracPro, please send me a postcard. If you do not use FracPro, tell me why and i'ill try to improve it. If you've found a bug, tell me as fast as possible where ! @endnode @node adresse My adress : Allenbrand Brice 5 rue du Manège 68100 Mulhouse FRANCE Phone : 89 45 33 37 @endnode @node Intro "Introduction" FracPro is another Fractals drawer program. It was written at first for @{"fun" link Copyright}, and to see if it can be as fast as its opponents. FracPro is the highly improved version of Mandel.... (DPAT #49). FracPro applys to those who want use fractals pictures in raytracing. Pictures are virtualy written in memory in 24 bits, but displayed in 1bit !! Advantages follows : - The size of the picture is only limited by the amount of memory. - Pictures are very precise. They can be used in mapping. - Computation isn't slowed by displaying. FracPro makes use of a special mode '@{"Oil-Paint" link rendu}' that create the most beautiful picture I've ever seend. @endnode @node Compatibilite "Compatibility" FracPro needs at least KickStart 2.0 FracPro needs at least 1Mo and @{"Reqtools.library" link merci} in drawer LIBS: 68000'version will need MathTrans.library and FPU versions the MathIEEEDoubTrans.library FracPro will use improved graphics routines if you're under Kickstart 3.0 Warning ! --------- For confortable using, you should have a FPU and FAST memory. @endnode @node merci "MERCI !" Thanks to Nico François for his reqtools.library Thanx Thomas" for - the assembly 68000 Code - IFF Documentation - the @{"ZOOM" link zoom}-idea - plaguing me to build an interface. Bêta tests have been done by Thomas Pimmel, Jean Marc Boursot. @endnode @node MDF "The last word" I'll be back @endnode @node ecran Picture size : More the size is high, better will be the results. It's only limited by the amount of memory. You should find the correct sier in relation with your configuration. The size will be round to the following multiple of 16. Yes but I have @{"PROBLEMS" link pbm} @endnode @node rendu "" Maximal number of iterations : If you don't expect to do big zooms, you don't need to change the default value. More the number is high, slower will be the computation. King of modes : None Only the 1bit picture will be drawn. Use it to find the interrsting zone and then change then mode. 2 colors 24bits pictures will only have two colors. Smooth Picture will have an interesting tablecloth aspect. Only for use at little zoom. OIlPainting The nicest, the slowest. No explain, try it ! Yes but I have @{"PROBLEMS" link pbm} @endnode @node bug "CONTACT ME" After a zoom, just before FracPro trace the 1bit fractal, some pixels are 'disturbed'. I'm working on that. If you'll find others @{"contact me" link adresse}. @endnode @node vs "FPU will help" 68000 version have a less precise 1bit @{"drawing" link rendu} Computation precision is limited at the motorola FFP. All version have optimized assembly code for best efficiency. @endnode @node doc FracPro exists in several @{"versions" link vs}. Each use the characteristics off the configuration concerned by. If several monitors are available, FracPro will let you choose your favorite. @{"Variation gap" link frac} @{"Default Values" link init} @{"Iteration level" link rendu} @{"Screen size" link ecran} @{"Modes" link rendu} @{"START" link comm} @{"STOP" link stop} @{"SAVE" link sauve} FracPro has a particulary mouse controlled @{"zoom" link zoom} option. Yes but I have @{"PROBLEMS" link pbm} @endnode @node frac "Gaps gadgets" You enter the intervals X and Y in the 4 gadgets above. Incorrect intervals will be ignored. Yes but I have @{"PROBLEMS" link pbm} @endnode @node stop "STOP gadget" By clicking on it, you stop the computation. There is no way to continue it at the level where it were stopped. Yes but I have @{"PROBLEMS" link pbm} @endnode @node comm "START gadget" By clicking on it, the computation is launched. If @{"mode" link rendu} is different of NONE, the 24bit virtual bitmap is computed at the same time. By clicking on @{"STOP" link stop"} computation stops. Yes but I have @{"PROBLEMS" link pbm} @endnode @node init "DEFAULT gadget" By click on it, the default interval appears. The others parameters won't be affected. Yes but I have @{"PROBLEMS" link pbm} @endnode @node sauve "SAVE gadget" By clicking on it you save the 24bit virtual bitmap, in the selected file. The saving format is IFF24 Byterun0 FracPro put in the comment the parameters used to creat the picture Don't save on RAM:, RAM: is precious. Yes but I have @{"PROBLEMS" link pbm} @endnode @node pbm "Common problems" 0) What ? I made a mistake, @{"I've no problems" link CardWare}. 1) How can this doc file be correctly read ? Use Amigaguide ! 2) Merci. This done is well done, mais I can't execute FracPro. You NEED @{"Reqtools.library" link Compatibilite} in LIBS: and @{"Kickstart 2.0" link Compatibilite} Look what the different @{"versions" link Compatibilite} need. 3) Danke, but the START gadget is always 'ghosted'. Your @{"interval" link rendu} or your @{"screen size" link ecran} are incorrects. 4) Waow, it's difficult, but the SAVE is always ghosted. @{"MODE" link rendu} must be different from NONE. 5) Sbrooô, But the mode in the screen is not nice. It seems that you want a to big precision, or the iteration number is too small. 6) Merci, But it doesn't @{"save" link sauve} in PACKED IFF. If packing doesn't bring enough earnings, FracPro doesn't pack. for example : the 2 colors MODE with the default values. 7) Yes, but it NEVER packs !!. You don't have enough memory. Actually, FracPro needs a big buffer to compress. It'll be changed in next versions. 8) When I choose DBLNTSC or PRODUCTIVITY, the screen gets black. You don't have stored in DEVS:Monitors the good resolutions youre monitor is able to display. @endnode @node zoom "Zoom" By clicking in the drawing zone, you can specify per mouse a new interval. FracPro compute automaticly ratios. Yes but I have @{"PROBLEMS" link pbm} @endnode
