Kalles Fraktaler 2

OK, Thanks. It seems obvious now.

I thought I'd mention that I've succeeded in applying perturbation theory to the burning ship fractal. I even have a sample program written in Fragmentarium glsl, that demonstrates the correctness of the formula (though my program is extremely inefficient and limited). The formula really needs a good CPU-side implementation to be useful.

So if you have the time and inclination, Kalle, I'd love to see the burning ship added to your program.

I was doing a zoom out sequence this evening and noticed when playing back what I had rendered in the keyframes editor that there was a sudden jump from e519 to e516 in the keyframes. I'd like to somehow render the missing frames but things start to get complicated when re-inserting frames into a numbered sequence. Is there a way to do this without resorting to a batch file renamer?

Sorry, there is no such function available in Kalles Fraktaler...

I just uploaded version 2.5.3

News:
 - A new fractal type, Burning Ship. Thanks to lazer blaster for the forumla! Available from the "Iterations" dialog.
 - Iteration control on zoom out sequences. This may fail though, on extreme fractals where spirals can have many times more iterations than deep minibrots, so it can be disabled by un-checking the menu "Use auto iterations".
 - Probably some bug fixes, that I don't remember.

The perturbation formula of Burning Ship from lazer blaster shows that it is indeed possible to render more fractal types with perturbation.
More formulas are very much appreciated, I challenge all of you with fresh mathematics knowledge!
For example:
Perpendicular Burning Ship - Zi = Zr * |Zi| * -2 + Ci, Zr = Zr^2 - Zi^2 + Cr
Perpendicular Mandelbrot -  Zi = |Zr| * Zi * -2 + Ci, Zr = Zr^2 - Zi^2 + Cr
Cubic Buffalo - Z = abs(Z^3) +C, The abs() function is applied separately to both the real and imaginary portions of Z^3
Newton fractals...

Hey, Kalle, I was wanting to make a kind-of feature request for the Key Frames Movie Maker side of the program.

It would help out a lot if the user could choose the output directory, mainly because the program is very heavy in hard drive activity with both the input and output streams being always open for the whole process. In cases like this, if the program isn't reading from and writing to the same hardware, its performance will easily multiply by a factor of 4, possibly up to 10 depending on the rest of the system's configuration.

The limiting factor that drops the performance in Movie Maker's current configuration doesn't even really have much to do with the width of the pipeline; it's the constant back-and-forth seeking mixed with the fact that it's constant switching back and forth between read and write modes.

Reading and writing from different hardware makes the data stream far more solid, so the data can smoothly move from the input drive through the program's code to the output drive without ever having to wait in line for any of the hardware to prepare to receive it.

Thanks again for the program.

All right! Burning ship here I come! Thanks Kalle!

[Chillheimer]

wow, so cool! thanks kalle! and laser blaster!!

[ellarien]

That was fast! Thank you!

I hit something a bit weird on my second attempt at a zoom. Can anyone tell me why the mini-ship at this location is so distorted? Throwing more iterations at it doesn't seem to help, at least up to the limits of my patience.

The Burning Ship's mini-sets aren't always ships. Sometimes they are copies of the celtic fractal (some say it looks like an aircraft carrier), or some weird elongated, asymmetrical pointy heart shaped thing, or a hybrid of any of the three. The exact nature of the mini-set depends on your zoom location.

Thanks! And south of the western antenna there aren't any minisets at all? Maybe I'm over-generalizing, but I've done a couple of zooms down there and found lots of pretty julia-like structures with nothing in the middle but a sort of shallow cusp.

Thanks all

@plynch27, I don't think it is disk io that is the bottleneck of kfmm. Because if you check 'test only' it is about as slow as when movies are made (if you consider it used 2 frames for test and 6 for real render)
So unfortunately I doubt it would get any faster reading and writing from different hardware storages.

Because it takes time to do thing such as color cycling. Our non-forum French friend Yann had made his own movie making program from KFB files, and so has SeryZone. I don't think their programs are much faster if you consider what they do.

Inverse smooth colour transition isn't showing up when the keyframes are loaded into the editor. The .kfr file was saved with inverse smoothing and if the file is opened the effect is present.
Thanks Kalle for a fantastic program. I'm looking forward to the perpendicular buffalo.

Kalle, my programs very stupid! I can't make anything!

So I was rendering a zoom sequence, and I changed the window size. Well that caused the render resolution to change to the window size, so I tried to fix the resolution, and the program crashed. Now I'm trying to resume the zoom sequence, but now it will only render the next frame and then stop without even saving the frame...

It might be because I deleted a bunch of black frames and the corresponding kfb files from the zoom sequence directory (these were frames that it never rendered before, I guess they were pre-allocated or something). Is there any way to recover from this disaster?
