    Why "man"? Why bring gender into it?

    Love it. The knights seem much more annoying / powerful than you'd expect.

    Politics aside, this is a fun type of puzzle!

    Does it actually matter for hash uniformity, though?

    I'm just here to comment on the CGA color palette on this website, lol. I always hated that video mode, but it looks good here when the magenta and cyan are limited just to links a…

    > The kinds of topic being discussed are not "is DRY better than WET", but instead "could we put this new behavior in subsystem A? No, because it needs information B, which isn't a…

    Presumably it was open & empty, so it's just a piece of glass surviving...

    Probably depends on your printer. And you should be able to adjust margins in the print setup.

    That's just what they call it in British English, and this is a BBC article.

    I know it wasn't ill-intended, but my answer is largely the same. I like the idea of using SDFs to define models and this was just a fun little side project. And FWIW, my project p…

    Indeed it does. Looks like their recent dev builds are way better. Good to know.

    I see you still haven't read the README.

    I just tried this in OpenSCAD and it crashed: intersection() { import("3DBenchy.stl"); sphere(30); }

    It's explained in the README. The SDF is evaluated on whole batches of points (32x32x32 tiles by default) using numpy. (And it's multithreaded.)

    It seems like you already understand the differences. I wasn't aware of those other projects. build123d looks pretty neat. Like most of my projects, this was just for fun and I mai…

    That feature requires getting pyopenvdb installed, which can be a headache, and I never really updated the README with examples, but it does work. There is one example script: http…

    It is kinda neat, but OpenSCAD's limitations are the main thing that motivated me to write this Python library to generate 3D meshes used signed distance functions: https://github.…

    I work on 3D printing algorithms at Formlabs. Lots of computational geometry.

    Kinda disappointing article. Not much substance regarding the link between geometry and chess, as suggested by the title. > Shapes are hypothesized to be formed by a programming la…

    Yes, you are describing a "people problem"...

    What did you not like about the SolidPython2 / OpenSCAD approach? What would you want from a different "3D engine" for this?

    This is so good, and based on some of these comments I don't think everyone is quite getting it.

    Possible counterpoint: LLMs are notoriously good at writing plausible sounding ideas that are wrong.

    So, if cameras have poor dynamic range, how are they getting away with a single exposure? They didn't explain that at all...
