The client sends a message to the server, saying "here is the formula to use, please give me the value of the pixels in the rectangle (0,0) to (100,100)", and the server sends back the pixels. The advantage of this would be that it would be easy to add distributed fractal drawing to Fractint, as well as an easy way to use the full power of multiprocessor boxes (by running several server processes on the same machine). I don't know if any of you have seen the program MandelSpawn which works on this model. You can get _very_ fast fractal drawing if you have a whole network of machines at your disposal 8-) . It could even work over the Net. Suppose a two people who read fractint-digest decide to cooperate. They both run the fractint server on their machine, and when running the client, they can get the other person's machine to draw half of the image and send it back over the Net - and instantly, you get twice the speed! Of course, this wouldn't be useful if they were both using their machines at full pelt all the time, but the typical PC is idle for 90% of the time - time that could be used calculating fractals.

The idea is to specify a small range, say 98% to 102% of the magnitude of c, and to color the pixel (white, say) if the iterate ever falls within that range, black otherwise. It creates a graceful series of loops that get more and more convoluted, showing the fractal shape in overview. It seems to work with other formulas, not just z^2+c. If you use this, you'll definitely need to use single-pass mode, and will probably want to anti-alias down from a much larger image to your final piece. I will post an image (infinity) done with this formula to the fractal pictures newsgroup. frm:minmaxc_jul { ; Kerry Mitchell ; colors the screen one color if the iterate falls between the ; high and low bounds, otherwise leaves it blank ; Julia set--c=p1, bailout=real(p2) ; low and high bounds are set through p3-- ; center of range = real(p3)*|c| (try 1) ; width of range = imag(p3) (try 0.05) ; color with single-pass mode and decomp zc=pixel, c=p1, r=real(p2), z=1 rc=|c|, k1=real(p3)*rc, k2=imag(p3)*0.5 lo=k1*(1-k2), hi=k1*(1+k2): zc=sqr(zc)+c, rzc=|zc| if ((rzc>lo)&&(rzc9Ne<7>eFQbJPZNOOWNCdM\ 7fN1iP<3>5Vc<9>NnZPqYRqY<6>kqS<4>mu\ x<3>zaY<13>T3pQ0rQ4r<13>Wyw<2>GJ1<6\ >x2N<2>pBmtRWxfE<9>SD1<12>ecO<5>KSUzz\ zCOW8MY<14>4pJ<11>EHC<4>si5<10>bka<4>\ 0jv<2>TEY<4>coOfwLfuN<13>hUp<4>Fjo<\ 13>8T67R29T4<7>ShOVjRZeS<5>x7_<7>ime<8>Wge cyclerange=0/255 } - ------------------------------------------------------------------------------- Kerry Mitchell lkmitch@primenet.com - ------------------------------------------------------------------------------- - - - ------------------------------------------------------------ Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------ Date: Tue, 06 Jan 1998 22:32:15 -0600 From: "Damien M.

I did a little research and found out - that the forward slash accented a is defined as ASCII decimal value of - 160. Congratulations, you've just discovered the extra space character in the Windows character set (which is different from the DOS character set). For example, in Windows, the forward accented a is code 225. Incidentally, any web page using a non-breaking space will generate code 160 in a Windows browser, and if you copy/paste in another app, you get this. If you want to search/replace non-breaking spaces in a Windows text editor, enter ASCII code 160 (in the method you describe) into the "find" portion of the dialog. I use TextPad rather than PFE (personal preference) and this works fine for me. Damien M.

Apparently my posts are readable to all and I can read everyone's posts. So I was befuddled, bemused and befumed when I saw the archive is one of the clueless email readers.

It will show the May-2 formula just fine but Sylvie's original will be screwed up. We need an archive free of 3D effects! That is why I posted Paul's formula on my page, 34k for just his. (I hope my late last night silliness was decryptable :-) , there were illustrations to go with the text.) A complete 1997 collection must be pushing a megabyte for just the frm + par. A weekly collection posted somewhere would be useful. Someone mentioned it already, as an automatic server thing. But if such is another UNIX dummy collecting =3D effects, forget it! If someone has a 1997 (& 1996) collection very well organized (and I'm not sure exactly what that means) that would be useful. And now would be a good time to start 1998 :-).

There are several client-server distributed M-set programs out there, I can dig up references. Portability is a real problem, although its significantly easier now that winsock has become popularized on Windows. However, that still leaves a socket implementation for DOS.

It is very frustrating to look at a formula with 6 blank spaces and not have any combination of numbers work after 30 minutes. Also, if a formula requires some sort of resent in the basic or other options, that is VERY handy knowledge to have. This morning I was messing with a formula that needed the decomp thingy (in the basic section) to be set to 256....like NO WAY am I going to know to do that. Having the pars is a great help....but having that type of info in the formula itself saves having to hunt for the par or gif that starts you out on the right foot.
