This would give the user some confidence about which formula is being used if there are duplicate named formulas. If the user wants to use a formula in a duplicate file, he can either specify the duplicate file in the par entry or use the "g" option in interactive mode to select, for example, "formulafile=_b_dup.frm".

There are so many different ways to distribute PARs, including having them embedded in the gif89a file, that I can think of no reasonable way to make *certain that the correct formula is being referred to. But I wouldn't object to seeing all the PARs on this list accompanied with their corresponding formula. Does anyone else feel this way? I feel, however, that slowing Fractint down because some folks don't give their formulas unique names is probably a bad idea. I'd rather hand-check for duplicate names if the PAR doesn't work, or ask the person who posted it to post the formula if people have problems. Hmm.. A random idea. I have no idea if it's a good one or even possible. Perhaps Fractint could be bundled with a small utility that checks your FRM files for duplicate names, a'la Orgform, and write a file containing this info. Fractint could then check this SINGLE file before running a PAR, and pop up a warning if formulas with the same name exist. Would that slow things down so much? This utility would only need to be run when new formulas are added, and it could be done manually by the user. Or perhaps a CHECKSUM could be run on the default FRM directory when Fractint is started, and the results written to a file. If the CHECKSUM changes, Fractint pops a message up telling you you may need to run the aforementiond utility. (I'd ask for a command-line option to override this behavior, of course...) One more thought... I sure hope someone named Roberta Carr doesn't start formula writing, or we'll all be screwed! - ------------------------------------------------------------ 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: Wed, 27 Aug 1997 14:01:41 +1000 (EST) From: "aalvaro@acs.itd.uts.edu.au" Subject: (fractint) bug I have discovered a bug in fractint?

I also promised to check into iterates.tga - and make sure it is working OK, but I haven't done this yet. ITERATES.TGA works just fine here. I have tested the Targa files produced with several different readers, and they are all legitimate files. A few non-standard readers might assume the header length is always eighteen bytes, rather than checking the header itself, but this is not a problem with FractInt. Adding extra parameters to ITERATES.TGA would be somewhat helpful, but most of the really cool coloring algorithms (in my opinion) require access to the entire set of orbits. This cannot reasonably be stored for every point--one image I computed recently had a *minimum* iteration count of over 200,000. At twenty bytes per iteration (two 10-byte long doubles) this is four megabytes, and that's just one point. Now figure I was generating it at 1600x1200... - We are about to start a truecolor development effort, and I'll be - looking for people who want to participate.

I don't find the time taken by my 486/33 to go through the non-duplicate formulas to be so great that I could not wait a few seconds more than that to make sure I'm generating the right image. Since most of the time it takes a lot longer to generate images than to find the formula (often several orders of magnitude), I just don't see this slowdown as a big problem.

I tried fractint under NT last night (full screen DOS session of course) and it worked with 320x200x256 and 640x480x16 but none of the VESA modes worked. Each time I picked one, my monitor said that the synch signal was out of range.

I don't know why the card would be sending an incorrect signal in a DOS session. (BTW, VESA is built into the Millenium's BIOS - you don't have to run a TSR). If anyone knows the answer, please let me know as it would be great to run fractint under NT. In the meantime I'll try other DOS programs and I'll email a question to Matrox tech support.

Rich, I have noticed this too. The full number of decimal places shows up when you press [TAB], but when you make a parameter file for a deeply zoomed image, the corner locations are truncated. This prevents folks from using parameter files to create very deep-zoom movies, among other things... I'm going to guess it's a limitation of the data type that Fractint is looking to read from a parameter file (double long float or something like that, eh?) Suprisingly, however, even though the corner locations are truncated, the parameter file seems to be able to recreate the exact image nonetheless! If there _was_ a way to produce a .par file with 100 digits of accuracy on the corners, I'd be psyched! I have my reasons...

I have tried to run Fractint under 2 different NT 4.0 boxes so far. Both are P Pro 200 with 128 Mb of RAM. One uses the Number 9 128 series II with 8 Mb of VRAM and the other uses the Matrox Millennium with 4 Mb of WRAM. Neither one will run Fractint in anything higher than 640x480. 8 bit color is only available at 320x200. So far I have not bothered to dual boot either of these machines with DOS. It's a great pity, too. I had really looked forward to being able to generate some of the more time-consuming fractals under the P Pro 200's. Any ideas as to why this would be the case?

Using outside=real will have no effect on the contents of ITERATES.TGA. >> Damien, Yup, you are right. I was just hoping that the code within fractint that writes iterates.tga would be modified (by Tim maybe ) so that it writes whatever is used for the color lookup instead. Then, for example, putting a pseudo-continuous iteration value into real portion of z and selecting real as the coloring method, iterates.tga would contain the pseudo-continuous iteration value. It could be scaled beforehand, by say, 1000, so that the data to the right of the decimal point would be included in the integer written to iterates.tga. A simple formula example follows which would work if fractint were modified in how it writes iterates.tga: ============================ TrueColor { ; formula to place a pseudo-continuous ; iteration value in the real portion ; of z. z = c = pixel i = 0 zb = 0 bailout = p1: IF (|z| <= bailout) z = z*z + c i = i + 1 ENDIF IF (|z| > bailout) zb = z z = z*z + c ; These extra iterations z = z*z + c ; are added as suggested ; by L. Vepstas to minimize ; the error function z = i - log(log(cabs(z)))/log(2) ENDIF |zb| <= bailout } =============================================== - ------------------------------------------------------------ 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: Thu, 28 Aug 1997 09:40:46 -0700 From: "Jay Hill" Subject: Re: (fractint) Searching for Formulas Looking for the lost formula?
