Title: Julia IFS example - "Kissing Circles"
Post by: David Makin on May 30, 2009, 04:04:43 PM
Hi all, Just a quick example of an escape-time 4 transform Julia IFS. Should work OK in Ultra Fractal 4 as well as 5, though in either case you may need to update your formulas. bye Dave MMF-KissingCircles {

Hello
I updated the formulas, but still got a bunch of errors "Could not locate parameter...in mm4.ufm"
The fractal looks OK anyway

That's very strange - I just downloaded mmf4.ufm directly from the formula database and checked it's identical to the version I'm using and it is so you should not be getting any errors reported. Try going to the formula database http://formulas.ultrafractal.com/ (http://formulas.ultrafractal.com/) browse the collection and download/overwrite "mmf4.ufm" in your public formulas folder with the version from there and then see if you get any errors when you try pasting the UPR from this thread again. I'd like to know whether that fixes the problem or not....if it does fix it then there may still be a problem with the full updates from the database.

Yes it fixed the problem. I checked the "Date modified" of the file, and it was still quite old, even after a monthly update.
But the image did not change: can you post it in to check if mine is correct?
thanks

It's OK, the image would have rendered correctly anyway :) The updated version of the "Escape-time IFS" gives you the ability to use Mandelbrots as transforms because you can tell the formula to add the pixel value in the non-affine function. This can't be done using standard convergent IFS methods. Here are two examples using slightly repositioned Mandelbrot transforms: (http://th00.deviantart.com/fs44/300W/f/2009/145/8/e/Mandelbrot_IFS_by_MakinMagic.jpg) Full version: http://makinmagic.deviantart.com/art/Mandelbrot-IFS-123729985 (http://th02.deviantart.com/fs45/300W/f/2009/147/c/c/Another_4_Mandelbrot_IFS_by_MakinMagic.jpg) Full version: http://makinmagic.deviantart.com/art/Another-4-Mandelbrot-IFS-123936424 I sent a message to the UF list informing Damien that updating the zip collections is still not functioning properly. For the moment the best way to check for UF formula updates may be to go to the UF formula database and check the "Recent Changes" list.
