A year (or longer?) ago a group called CygnusSoft released a demo version of MandFXP, a mandelbrot generator. I believe they were in Vancouver. Does anyone know if the release version made it out? If so, could you let me know the details on how to obtain a copy? I'd also appreciate hearing from anyone who knows of mandelbrot programs along the lines of MandFXP. Basically I want to generate graphics...so I'd be more interested in programs with stronger graphics features. Thanks for any pointers.... Ned Schultz nschultz@polyslo.calpoly.edu

Nothing is as nice as MandelVroom. Nothing. An earlier version is on one of the Fish disks, another one is being prepared for release. (Right, Kevin?) I've spent a lot of time playing with it, and use it to find coordinates of `interesting' areas which I can use to display on my X workstation at school (where nothing even *approaching* Mandelvroom can be found.) -tom

RMand is quite quick, but doesn't have all the bells and whistles that I would like to see. Briefly, rmand calculate the colors for the pixels forming the perimeter (the entire perimeter) of the screen and if the same, does a flood fill. This tends to flood the 'black' areas (those actually in the set) quickly, where most other algorithms spend most of their time. Anyone working on a full featured Mandelbrot program should consider this algorithm. I haven't implemented it, but understand it pretty well and will be happy to correspond via e-mail with interested parties.

MandelVroom does not use the recursive perimiter algorithm for a number of reasons: 1. It is not as precise as the brute force method... If the computer were indeed calculating a continuous perimiter (i.e. an infinite number of points along the perimiter) then it would be a good idea. I indeed implemented it once long ago (non- recursively) and chose not to keep it. 2. This algorithm works nice for pictures with large amounts of the Mandelbrot set in it, but slows down the the non-Mandelbrot stuff. I find large sections of black boring, so the algorithm would only get in the way for most of the really pretty pictures. 3. MandelVroom is a "full figured" Mandelbort/Julia picture generator already. Some of it's features: -Uses configurable custom screen (HAM is only mode not supported) -Project oriented. Multiple pictures on the screen at once. -Multitasking. Can have as many projects open and generating (simultaneously) as you want. -Save/Load projects (can save partially generated picture, reload it and resume) -Borderless projects. -Zoom in/out as well as pan around. -Powerful picture coloration tools that allow you to recolor pictures while they are generating. -Online help for every gadget and menu item. -Orbits... Tom asked for these... -Five Math modes: -68000 fixed point, 68020 fixed point, FFP, IEEE, 68881 assembly. With five math modes for Mandelbrot and Julia generators, that makes 10 generator routines. If we add another dimension for perimeter chasing that makes 20. Ten with perimeter chasing. Ten without. I've been very busy lately preparing to move into my first house, so MandelVroom release has been slow in coming. The release date has been a month away for three or four months now, I hope it really does happen soon. MandelVroom will be released with source, so you can add it if you want. Good luck with some of the code. Most of it is REALLY icky. I've also been very distracted by Fract3D (a new 3D fractal generator I've been working on.) It produces HAM pictures that are really nice.

They did send out release versions to those who sent in a ahareware fee (including one to Arthur C. Clarke). They have also, very recently, released the entire package (source included), as freely distributable. I don't know when it will make it to Usenet though. The whole package is just over 500K after zooing. -larry -- - Don't tell me what kind of a day to have! - +----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca or uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 | +----------------------------------------------------------------------+

I'ld like to second this endorsement for MandelVroom. I've had the privilege of being a tester of this program and I gotta tell ya - it's slick. Besides all the neat features (like '881 and '020 support) it also has one of the best user interfaces around. I can't wait till it's done (are you listening Kevin?). -- Eric Cotton Commodore-Amiga (215) 431-9100 1200 Wilson Drive {uunet|pyramid|rutgers}!cbmvax!eric West Chester, PA 19380 "I don't find this stuff amusing anymore."
