Fractile plus is available in the iOS App Store.
First I’d like to second on the “wish of many” about cycling the colourmap. I guess it’s not so easy due to the worker thread communication overhead and due to the mapping with the gamma correction as you use it right now.
Second, I’d like to tell further areas where I had thoughts or wishes. In terms of calculation, I’d love to see less dynamic calculation—when I’m watching the fractals, I would like to be not distracted by the calculation updates all over the screen; rather I would prefer it either to have some precaching designed for the tapping magnification step, or, just one update in one tile rather than updating the tiles as they are calculated.
Lastly, it would be great if you could improve the Julia set preview resultion on the iPad. I have an iPad 2 and the preview is way less beautiful to watch than the full calculation, it seems it has a 2×2 pixel resolution?
That’s it for now, I think Fractile+ is the best app for Mandelbrot calculation I found, although it could borrow some neat features like precaching and one-step update from Brot. But the calculation is more stable than that of Brot, and the Julia set feature is just beautiful. I never dared to investigate myself the known claim that one “could fine small Julia sets in the Mandelbrot set”. It is really elucidating. The colours are beautiful. I think you did with what you did really a good job, meaning you didn’t implement everything, but what you implemented seems rock-solid, and you made it free, Thank You!
Hey, I’d likee to know, why Fractile+ has been banned from the german App Store.
Sorry about that, my apple dev membership expired – I’ve just renewed, so should be back very soon.
The Best Fractal in App Store!
Infinity zoom PLZ!!!
Drop precision after x14.4E12! Precision limit bypass, go simultaneously! Maybe Hold and modify…
App is great but I cannot find the fractals I have saved. Guess because the app crashes every time I want to save it to my iPad3. Would be nice to learn if that’s just because I am doing something wrong or because iOS6 does not (no longer) saving user files
Really? The images should appear in the camera roll. Does it get to the stage where you have to wait for a progress bar to complete?
That’s what I am doing:
Open the App …I see the start version of Mandelbrot – my last preference = red background black center is still active
I touch the wheel top right and select “Save image”
Select 1646×1236 pixel (funny, last time I selected this it showed a third size 700 x ? or so)
Blue dialog appears computing … with a moving bar …
Then I see the regular iPad desktop … Fractal Plus has not been quit but moved to the bottom = closed program
Same with Julia … here I get 3 options to save but same effect … program disappears and hibernates an the bottom.
I open iPhoto and search for any kind of new photo under photos, albums or places – nothing.
As a test I took a picture of myself with the iPad camera … its there in iPhoto
I also looked iBooks and Kiosk nothing
I inspected my iPad via the software “iMacsoft iPad to Mac Transfer.app” … nothing.
The system on my iPad is iOS 6.0 (10A403)
By the way – on my iPod with iOS 5.1 (9B206) the program works fine – in mandelbrot I also get 3 and not only 2 sizes.
So – any idea what I should check further out?
OK, thanks for the report – looks like it has just plain stopped working with iOS 6. This might take a while for me to fix unfortunately, I’m way behind on the OSX upgrade cycle.
(The random-seeming choice of image sizes is normal BTW – the options you get just depend on how far you’re zoomed in.)
Well – good luck, at least you can jump all the way to iOS 6.1. Yet you may want to wait, until Apple has sorted out the bugs which may still exist (with the iPhone5 ?)
