zoomasm assembles zoom videos from exponential map key frames, as exported by #Fraktaler #Fraktaler3 and other software for
#DeepZoom #fractals #MathArt
Changes in version 3.4 (2025-06-11) since version 3.3 (2023-07-13):
- support dual channel iteration counts (N0+N1) for very high iteration counts (above 4 giga iterations)
- update to current library versions

changes since v2.1 (July 2023) are too many for this toot, the main new feature is flexibile colouring with GLSL shader fragment.
changes since v3~preview (June 2024) are quite small (a few bug fixes, some enhancements).
still not fixed the #zoomasm 4.0 compressed width table bug mentioned in the previous toot dated July 2023.
and I found another bug today: loading KFP palettes (from Kalle's Fraktaler 2) works fine in zoomasm 3.3, but in zoomasm 4.0~pre the timeline window (which can now be used to sequence uniform variables) doesn't get initialized with the values from the file. this means everything is 0 and you get a blank black screen.
I should also make it possible to load palettes from #Fraktaler3 TOML files. And while I'm at it I should make it automatically load either the KFP palette or the F3 palette that will most likely be embedded in the metadata of the EXR files used for the zoom sequence (pick the first keyframe to avoid confusion).
Meanwhile (hopefully, needs more testing) finished the support for high iteration counts (two uint channesl N0 and N1 for low 32bits and high 32bits) in what will be zoomasm-3.4 (and also added to 4.0).
fixed two failure modes in #Fraktaler3 for #FractalFriday (thanks to FractalLion for bug report).
Previously:
- if saving TOML failed, program exited abruptly with uncaught exception
- if saving EXR, PNG, or JPG failed, program would continue without reporting the error - this could lead to calculation of a whole zoom out sequence with nothing to show for it (arguably worse than the crash)
Now:
- if saving fails, a modal dialog box is shown which blocks everything until Ok is clicked (and batch rendering is aborted if it was in progress)
#fraktaler #fraktaler3 v3 final is still not released after almost a year... trying to squash final #bugs in the coming weeks, so now would be a good time to check the #beta to find problems, so I can #fix them...
known bugs that have been fixed already but not yet released include:
- negate Y option has bad reference leading to glitches / fantasy fractals
- floatexp opencl coordinate glitch (looks like horizontal stripes of the image repeated vertically) with deep zooms on GPU
- newton zoom dialog has been improved
- some other small things
