Kalles Fraktaler 2.7.6 available

[Kalles Fraktaler]

One new feature: Slope encoding!


Some day... I will update the moviemaker to include all the new features of Kalles Fraktaler

[Chillheimer]

Another great improvment!
the awesomeness of kf keeps zooming into infinity!  


(and I hope someday will come soon  
i really miss some of the new stuff in the movie maker..


from time to time I take a look if "frax" is finally available for android or windows.
http://www.fract.al/showcase 
Sadly it isn't yet..
I think it has the coolest colourings and variation of all m-set explorers..
As it was just a few days from aleph suggesting slope encoding, maybe a look at this gallery inspires for even more cool features?
the programmer is here on the forums as well - http://www.fractalforums.com/announcements-and-news/introducing-frax!/

Running through Wine on Linux Slackware the 32 bit version works fine, but the 64 bit version 2.7.6 throws an error at me:

Code:

err:module:import_dll Library MSVCR120.dll (which is needed by L"Z:\\tmp\\kalles\\fraktal_sft64.exe") not found
err:module:LdrInitializeThunk Main exe initialization for L"Z:\\tmp\\kalles\\fraktal_sft64.exe" failed, status c0000135

Older 64 bit version 2.7.4 does run fine.

Playing around with the slope function. Two of the first creations with this new function:





Rendered at 7680px, color levels adjusted in the gimp

Cool. (or hot, cool originated in africa) My feature add had worked;)))

[Chillheimer]

I love it!

Thanks a lot!
Next step is to figure out how to make a movie with this encoding...

In my zoom assembler I alpha-blend between successive pairs of images (scaled up so one is 2x2 times the size of the other), cropping to a central part completely covered by both images (so no seams).  I normally use distance estimate rendering, and carefully chosen transparency values relative to zoom scaling minimizes visual strobing.  This approach might work ok for slope rendering too, I haven't tried it yet.  I blogged about the blending (and some other stuff) here:

And I have an implementation here::

One new feature: Slope encoding!

I think I found a bug:

I rendered a zoom out sequence with jpegs, but after the first frame it seems the slope ^ box in the colour editor gets reset to 1 making the effect invisible in the jpegs.

I tried the 32bit version in WINE, hoping to assemble jpegs into a movie with my own program to see if it looks ok..

[Alef]

Colours very much depends by what function they are interpolated. Just did a small research about palletes

Well, each time you zoom out a view with factor 2, the distance between pixels will be doubled. Therefore the slope strength need to be half, and pretty soon it becomes zero.
If you want it to be exact.
But I am finding a way in KFMM to solve this...Because the appearance is about the same for a logarithmic decrease of the slope strength.
But that must be applied per each movie frame, ie not only key frame.

I want it to stay constant, perhaps this could be an option?  Not urgent really, as I've written a little program to colourize .kfb files to .ppm, which I can assemble into a movie with my own zoom program that I mentioned earlier.

Here's a video (1min, 15MB):

EDIT: and another with the brightness/saturation reversed:
http://mathr.co.uk/mandelbrot/2014-12-12_rainbow_slope_2.ogv

It's a variant on slope colouring, where the normal direction determines hue and brightness+saturation is higher the steeper the slope.  I attached the source and Makefile.

Hopefully you can see that even though the slope strength remains the same, the alpha blending doesn't look too bad and the overall effect is interesting.


EDIT2: I worked on it a bit more, getting effects similar to distance estimate colouring:

http://mathr.co.uk/blog/2014-12-13_faking_distance_estimate_colouring.html

would be nice if this "fake DE" could be added as a colouring option in KF!  Ideally with an option to multiply the fake DE colouring with the other colourings available
(though, appearance varies with zoom level so its incompatible with KF movie maker...)

Older 64 bit version 2.7.4 does run fine.

Just tried the 64 bit version of KF 2.7.6 on Windows 7. Basically it gives the same error, but in different words:

"The program can't start because MSVCR120.dll is missing from your computer. Try reinstalling the program to fix this problem."

For comparison, the 32 bit version of KF 2.7.6 works fine.

MSVCR120.dll is Microsoft Visual C++ runtime library, required for programs that were compiled with Visual C++ 2013. You can get it by installing the 64-bit Visual C++ Redistributable Package for Visual Studio 2013. Download link:
http://www.microsoft.com/en-us/download/details.aspx?id=40784

(Or just download Mandel Machine and copy MSVCR120.dll from there )
