Iterated Dynamics 1.3 released
by Richard 30 Jun '25

30 Jun '25

Hi, Iterated Dynamics 1.3 has been released! This release is a bug fix release. Highlights of this release are: - Color channel values now retain their full 8-bit precision (#47, #61). (I bet you didn't realize that even though VGA displays have supported 8-bits per channel in the color table since 1991, FRACTINT has been silently truncating your colormap values to 6-bits!) - The savetime parameter functionality for automatic saves during long rendering has been restored (#43). - The delay value is properly displayed for the ant automaton (#287). - Fractals using the log function now render properly (#295 and others). - Discussions of integer math computations were removed from the documentation (#303) Consult the change log in the help file or the list of issues closed for milestone 1.3 for a detailed list of changes.

Some questions about formula semantics
by Richard 27 Jun '25

27 Jun '25

Hi, For background, see this github discussion message: <https://github.com/LegalizeAdulthood/iterated-dynamics/discussions/300#disc…> I haven't tried these out in FRACTINT yet, so I thought I'd ask here and maybe someone would know :) 1. Can an assignment operator be used in a sub-expression? e.g. is 'q=4+(w=6)/2' valid syntax? If so, what are the values of q and w afterwards? My expectation is yes, this is be valid syntax and the values should be q=7 and w=6. 2. Do the logical operators && and || have "short-circuit" behavior like they do in C/C++? My expectation is yes, meaning that e is unevaluated in the expressions '0 && e' and '1 || e'. No assignment expressions in e change variables, no values in the expression e are computed. Also, I note that the use of \ to continue a single logical statement across multiple physical lines doesn't appear to be documented for the formula type, although it's used in plenty of .frm files.

Iterated Dynamics 1.2 released
by Richard 04 Mar '25

04 Mar '25

Hi, Iterated Dynamics 1.2 has been released. Version 1.2 is mostly a code cleanup release that removes integer fractal types and replaces them exclusively with floating-point types. This change was made to simplify the existing code paths in preparation for migration to wxWidgets in version 2.0. New Features in Version 1.2 - Native Windows file browse dialog for opening files. - Improved version handling with the reset parameter. - Improved version handling when reading GIF files. - Improved version handling when writing GIF files. - Improved rendering of mathematics in the HTML help. A number of bugs were also fixed; details are in the help. Download: <https://github.com/LegalizeAdulthood/iterated-dynamics/releases/tag/v1.2.0> Project Page: <https://github.com/LegalizeAdulthood/iterated-dynamics> Online HTML help: <https://legalizeadulthood.github.io/iterated-dynamics/> Thanks, -- Richard -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Terminals Wiki <http://terminals-wiki.org> The Computer Graphics Museum <http://ComputerGraphicsMuseum.org> Legalize Adulthood!

XFractint SDL starts in small window
by david 17 Feb '25

17 Feb '25

I use a 4K display. I have xfract, the non-SDL Linux version, it accepts the "-geometry 3840x2160" command line option to use the full screen and works fine. XFractint SDL just reports an error and comes up in a little 920xsomething window. The window can't be resized. I had also added an entry to the fractint.cfg file so I could manually select the 4K resolution. When I start XFractint SDL and select that option, I sometimes get an error about "stack smashing detected" and the program doesn't start. And other times it simply returns to the existing window size with no changes. I'm running Debian Bookworm on a Ryzen 9 9950X CPU, AMD GPU, 128GB of memory, 728GB of space available on a 2TB NVME drive. Ideas? -- David W.

Iterated Dynamics 1.1.1 hotfix release
by Richard 07 Feb '25

07 Feb '25

Hi All, When I added inline image markup for the HTML version of the help, I forgot to suppress them for in-program help resulting in some asserts in the debugger and junk output in the in-program help screens. This has been corrected in the hotfix release 1.1.1 that is available on github: <https://github.com/LegalizeAdulthood/iterated-dynamics/releases/tag/v1.1.1> Version 1.1.1 will upgrade version 1.0 or version 1.1 in place if you are using the Windows Installer (MSI) package.

thanks for your help. I tried Chrome and it works! I have used Fractint for years and years and a very grateful of your work. ------ Original Message ------ From: legalize(a)xmission.com To: fractint(a)mailman.xmission.com Sent: Tuesday, February 4th 2025, 12:55 Subject: [Fractint] Re: Iterated Dynamics 1.1 released Hi, In article <6159bb77.2d057.194ce0a56f6.Webtop.18(a)sympatico.ca>, dastew dastew writes: > I an using ubuntu 24.04 and firefox and I clicked on the download page > and all I get is: It's a bug in your browser. Try using one that is less buggy :) In plain text, the surrounding of a URL by <> is how the URL is distinguished from other text: The characters "<" and ">" are unsafe because they are used as the delimiters around URLs in free text "Uniform Resource Locators (RUL)" Your browser is just scraping along through the text and is heuristically looking for anything that starts with a URL prefix like https:// and considering everything up to the next whitespace character to be a URL. However, there's no point in downloading Iterated Dynamics 1.1 for ubuntu anyway because unix support won't be restored until 2.0. -- Richard -- "The Direct3D Graphics Pipeline" free book The Terminals Wiki The Computer Graphics Museum Legalize Adulthood!
