Mandel Machine

[stardust4ever]

Well, for 2,000,000,000 iterations we need array of 2billions. double. We need (8*2B)=16,000,000,000 bytes =  14.901GB RAM for reference! + 10240x5760 image (10240*5760*4 = 225MB) Totally I need maximum 16GB for rendering final minibrot's image. Botond, Why I can't do this???



Sorry =( My idea works with integer, but doesn't works with float numbers =((( Idea was be @Compressing reference@

I'd like to see what you are rendering that takes 2 billion iterations. Good luck rendering whatever it is. Let us know what you find...

You would actually need twice that amount, because the reference has real and imaginary parts, both stored in double precision. But stay tuned, I'm working on a solution that will reduce the memory needs dramatically.

I rarely do areas more than a few millions. Unless you are exploring the minibrots of minibrots the same way you would the main fractal, there is no reason for the iteration loop to range into the billions of iterations. In fact, one of my vids with the highest iteration density was also fairly shallow, at least by modern computing standards:

Thank you!
Ha! How I can render it? MM support only 400M iterations and non-stable in RAM usage!

A new beta version is available, containing mainly bugfixes. The launcher now starts the JVM with a maximum heap size determined by the amount of free RAM in the system.

Very nice, Botond! Thank you!
P.s. What about deep zooming as mouse wheel? Mouse wheel do 1 zoom/sec. Double click 2zooms/second. Can you make deeper zoom using mouse???

Mouse scrolling is pretty darn efficient but I've gotten used to not using it because previous versions of MM crashed with multiple scrolls during orbit calculator. Once you get past a couple thousand zoom levels, assuming smallish resolutions like 640 or 800 pixels for previewing the fractal, the limiting factor becomes not rendering the image but the orbital.

At this point, it becomes more efficient to increment the scroll by drawing tiny rectagles. I turn off glitch fixing unless I've got a complex Julia that really need enabled it to find the centroid of the image. On my desktop with large monitor, I can average about 5 zooms per click by drawing tiny rectangles. This is a far cry from the 1 zoom per click the scroll wheel gets you. 4 or  8x (2or 3 zooms) would make a balanced option for scrolling inwards, like the menu in Kalles Fraktaler.

Also I have a small request. Since you don't have a dedicated palette maker, can you support the import of Kalles Fraktaler palette files directly? Well then again I can screenshot palette makers of other soft like Fractal Extreme and crop in the thinly bar of palette data using a photo editor like Paint or GIMP. Fractal Extreme does bars of Palette data rather than smoothe transition though so I might need to apply a Gaussian blur effect on the bar to reduce posturization effects. I'll have to experiment more.

Botond, why glitch-correction can't guess mini-brot? I wait 5 minutes for glitch and 38 hours for it's correction! Please, enable guessing!

Good point, it will be included in a future release.

Please, make also zooming (using rectangle) without double-click!

This is a small update, but an important one as it enables Mandel Machine to come out of beta status.
Changes:

• A time limit can be set in the new Settings box (at the very bottom of the scrollable vertical controls), and if the computing time of the image exceeds the limit, the computed iteration values are saved in history, so the image will not have to be recalculated when returning to that state later.
• Mouse navigation parameters can also be modified in the Settings box.
• The settings are saved on every change, and loaded on each startup.

It is great!

The attached location breaks the series approximation, however the other locations I have on the x-axis (i.e. im=0) are working without problems.

[SeryZone]

Dear Botond! Thank you so much!

[Botond Kósa]

A small update is available, addressing bugs introduced by the saving of iteration data in history. It was corrupted when the iteration span was larger than one million, and the process of saving and loading was sloooow

Tried the version posted just before this slight update and it's fast, and so far has not crashed.

Well done Botond, I'm really glad you're out of beta.
