Fragmentarium / Re: I can't get the newest version to work
« Last post by fractalrock on Today at 12:34:03 PM »
You have been so incredibly helpful and I feel bad to keep coming to you with problems I'm having.  I think it's great that you're updating Fragmentarium.  I only just discovered it the other day and I love it.

I'm still getting error messages.  Here is a screenshot of what I'm seeing.

I'm running Windows 10.  I have 32 GB RAM, 1 TB SSD, the latest drivers for the graphics card, Intel i7-8550U processor.


P.S.  Thanks for the link to the website.  I'm glad there is a website for this program.

Dry Fern

Same location as previous, but wildly different color scheme, the colors of the forest.
XenoDream lets you do that (and much more) without any maths. The transforms are parameterized as scales, skews, rotations and position. You can edit them interactively with the mouse by dragging the numeric controls, or moving the boxes around. In addition, it has many primitive shapes, so for example you can add a sphere to a Sierpinski triangle. The trial version lets you play as much as you like; it just stops you from saving pictures and a few other things.
Hi Friends,

This is my first post on the new forum. I am trying to implement perturbation theory from SUPERFRACTALTHING MATHS by K.I. MARTIN. I couldn't really understand it but then found Shirom Makkad's MandelbrotPerturbation program on GitHub.

When I ran it, it certainly gave the sort of speed enhancement I get from Kalles Fraktaler, but seems to be plagued by glitches.

Does anyone have any experience with this program?

I suspect the precision is lost in the step:

      xZoomPoint = atof(xZoomPointin);
      yZoomPoint = atof(yZoomPointin);

where these variables are long doubles (64bits in Microsoft VC++). But I don't really understand perturbation theory very well.

Actually, what I really want is a library source that is platform independent that looks like:

int  MandelbrotPerturbation(int ScreenWidth, int ScreenHeight, long MaxIterations, char *xZoomPt, char *yZoomPt, double ZoomWidth, long*PixelArray)

image size is given by ScreenWidth and ScreenHeight
Maximum number of iterations tested = MaxIterations
xZoomPt, yZoomPt are strings containing the full number of digits for the centre (or corner) of the complex plane
ZoomWidth is the vertical size of the area is the complex plane
PixelArray is an array of all pixels and their iteration count

Any help here would be greatly appreciated

oops  >:( fixed  :-\

Laptops may get cooked by FragM :(

see this link before running

the welcome screen shows when you first run FragM...
This is your first run of Fragmentarium.
Please read this:

(1) Fragmentarium requires a decent GPU, preferably a NVIDIA or ATI discrete graphics card with recent drivers.

(2) On Windows Vista and 7, there is a built-in GPU watchdog, requiring each frame to render in less than 2 seconds. Some fragments may exceed this limit, especially on low-end graphics cards. It is possible to circumvent this, see the Fragmentarium FAQ (in the Help menu) for more information.

(3) Many examples in Fragmentarium use progressive rendering, which requires Fragmentarium to run in Continuous mode. When running in this mode, Fragmentarium uses 100% GPU power (but you may use the 'Subframe : Max' spinbox to limit the number of frames rendered. A value of zero means there is no maximum count.)

Thanks for responding.  I went to the new release page but I still see the version for 02/09.  Am I supposed to download all the files or just the 7z file?  I have an NVIDIA GeForce MX130 version 418.81 graphics card.  (I went to Control Panel to figure this out.  I don't know much about hardware.)  This is a brand new laptop that I just bought a couple weeks ago.

I've attached an image of what I'm seeing on the release page at Github.  I deleted the one I had on my hard drive and downloaded the one under 02/17 but I still get the same error messages.

Thanks again!
What is "blinds direct" ?

I just updated github with a couple of patches a few minutes ago, release tag 190217

I also ran the winex version here and loaded BioCube.frag using the includes from the package distribution...

what kind of GFX card and driver version?

I am looking at playing with the IFS's of common fracals like Sierpinski triangle and tetrahedron in 3D and 2D. Just changing up the affine transformations to make variations. I don't need randomization, animation, or such things.

I can do the math to adjust the transformations, but with difficulty.
Ideally the software could let you build the transformations in natural language (mirror across x=3, scale by such-and-so percent, etc.).

Can anyone think of a program like that? I am on Windows 7 and 10. Any replies would be appreciated.
Fragmentarium / I can't get the newest version to work

I just downloaded and played around with Fragmentarium 1.0 yesterday.  Today I wanted to find a newer version and ran into 2.5.0.  I went to the page at and downloaded the  Fragmentarium-2.5.0-190209-winex.7z file.  I unzipped it and ran the program but got error messages.  Version 1.0 works fine for me.  Why isn't 2.5.0 working?  What am I doing wrong?  I've attached an image of what I'm seeing.  Thanks for your help!
