Hello! I'd love it if this and mrcal could work together. Do you support mrcal .cameramodel files? If not, can you do that? Is your splined representation compatible with the mrcal splined stereographic model? If not, can it? Is your splined lens representation better in some way? If so, should mrcal use some of that logic? I didn't see any documentation about it. If you think the mrcal distribution methods could be improved, and are willing to help improve it, I would be very amenable. Let's collaborate to make both projects better!

I would love for us to move past the idea that non-pinhole projections have "distortion", and we should strive to remove this "distortion" by reprojecting stuff to pinhole models. In practice, ALL projections distort straight lines and/or shapes and/or sizes, so if you use the pinhole projection everywhere, your images look like crap (see iphone wide-lens camera output for instance). Most of the normal non-pinhole projection functions work fine for wide lenses, while behaving like a pinhole lens with long lenses: https://en.wikipedia.org/wiki/Fisheye_lens#Mapping_function
Tangentially, are there any good map websites out there that show me the elevation at a point I click on?
I've found a lot of providers lacking in this department, even if they clearly have height data for showing contours/3d views.
This is real clunky from a browser. https://caltopo.com can do this from a map (right-click on the viewpoint, point-info, simulated view). The horizonator (https://github.com/dkogan/horizonator/) is a hackable implementation; has a FAST local gui, and can easily be extended to do other stuff.

Macro-economic policy is political. I'm sorry.
This is a new release of the mrcal camera calibration and lens modeling library.
Fun! If you want to compute these yourself and/or if you like hiking into the mathematically middlest-of-nowhere location, here's a good blog post: https://notes.secretsauce.net/notes/2015/05/06_poles-of-inac...
After years of admonition discouraging me, I’m using Python for a Windows GUI app over my usual C#/MAUI. I’m much more familiar with Python and the whole VS ecosystem is just so heavy for lightweight tasks. I started with tkinter but found it super clunky for interactions I needed heavily, like on field change, but learning QT seemed like more of a lift than I was interested in. (Maybe a skill issue on both fronts?) Grabbed wxglade and drag-and-dropped an interface with wxpython that only has one external dependency installable with pip, is way more convenient than writing xaml by hand, and ergonomically feels pretty pythonic compared to QT. Glad to see more work going into the windows runtime because I’ll probably be leaning on it more.
Look at pyfltk also. I haven't used the windows builds, but it's real nice on GNU/Linux.
Well, there are big differences in how aggressively things are patched. Arch Linux makes a point to strictly minimize patches and avoid them entirely whenever possible. That's a good thing, because otherwise, nonsense like the Xscreensaver situation ensues, where the original developers aggressively reject distro packages for mutilating their work and/or forcing old and buggy versions on unsuspecting users.
Huh? I contribute to Debian; I don't aggressively patch anything. You can too.
