I thought I would throw out a 'Nice Job!' to Dave Platt for the MandelZot 1.4.1 program that came down the comp.binaries.mac pipeline recently. For those who have color capabilities, you can make some really nice pictures of the Mandelbrot set. Even without color it may be good, but color is really nice. Special thanks for adding the notification manager and closing windows in the background feature. When switched out under Multifinder, MandelZot closes all of its windows (unless instructed otherwise) and continues calculating. When it is finished, it uses the notification manager to alert the user. When you switch back, you have the completed picture waiting for you. On a side note: The samples that came in the third posting would not unstuff for me. They unbinhexed fine, but then gave an error on unstuffing. Was this a widespread occurrence?

Absolutely fantastic! And it's really quick on a IIx!

For some reason, Un-binhexing from Stuffit works, whereas Un-binhexing from
BinHex does NOT work. Why,... I don't know.

This is one of the best implemented and documented programs to come along that I have seen. And considering that it is FREE, double congrats! Very well done.

Mandelzot is a very nice program, which I have used to generated Mandelbrot picture for use in some tech and conference papers. I have but one current request (maybe two), There are a host of very interesting iterative equations other than z(t+1) = z(t)*z(t)+c, such as z = x + iy, z(t+1) = exp(z) = e sup x e sup iy = e sup x * (cos y + i sin y ) z(t+1) = sin(z) = 1/2i* (e sup iz - e sup iz) z(t+1) = cos(z) = 1/2* (e sup iz + e sup iz) while I doubt you can do disk cutting, iterative evalution is not hard. Was the source posted? If so, where can I get a hold of it to add these mods. Thanks Bruce Bruce Rosen ARPA: rosen@CS.UCLA.EDU UUCP: ...!ucbvax!ucla-cs!rosen

Mandelbrot produces such beautiful pictures, I felt an immediate urge to reach for my camera (this happens about once every 100 years for me). So I spent an evening taking pictures of my screen!!! Hats off to Dave Platt for an excellent, beautiful program! Don Gillies, Dept. of Computer Science, University of Illinois P.S. My only disappointment was that later, after I had saved a file in "store rasters" mode, it would not load, and had obviously not dumped the picture to the file (the file was only 1.5K)

I agree, MandelZot is a neat little program. I have two things on
my wish-list, however:
1. I'd like to see a data compression algorithm built right into
the save routines in the program. I'd rather not have to drag
out Stuffit to get a file down to reasonable size.
2. When I was mucking around with my fractal program, a display
mode I particularly liked was to recursively subdivide the screen
into quarters. Calculate the dwell of the lower right corner and
color the whole quarter that color. *Eventually* you get the
whole picture at maximum resolution, but you also get a good
feel quite quickly of what it will look like. Advantage: if
it's not interesting, you can go on to something else.

I'm new to the Mac, and am also impressed with Dave Platt's Mandelzot
program. Can anyone tell me if there is a screen capture program for color
Mac II's similar to Sun's screendump program? Hopefully one that generates
files with a well-documented format?
Thanks,

Let me add to the general praise for MandelZot, and also to the list
of suggestions:
1) I'd love to see a third algorithmic option, in addition to the
disk-cutter and DivCon, that would start with a chunky lo-res
display and iterate through progressively higher resolutions
(the way SuperMandelZoom works, for example). It's frustrating
to have to wait minutes, or even hours, to get the 'overall picture'
and then realize it wasn't what I was after in the first place.
2) It would be nice to have the option to make the window full-screen,
so that the resulting image can be easily made into a startup
screen or 'desk PICT' without 'margins' around the edges.
Great job, Dave!

Capture, a commercial product, from Mainstay is probably the best I've used. It will allow you to dump to a PICT file or to the clipboard, and will even capture menus.
