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

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 and headers!

> 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 available to that subsystem in context C, and we can't expose that without rewriting subsystem D, but if we split up subsystem E here and here..."

Hmm, sounds familiar...

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 predates build123d.

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 mainly made it for myself. I'm a DIY kind of guy when it comes to software. I just throw things up on GitHub in case anyone else can get some use or inspiration out of it.

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:

https://github.com/fogleman/sdf/blob/main/examples/mesh.py

You basically just say:

f = Mesh.from_file(path).sdf(voxel_size=0.25, half_width=1)

Then you can operate on `f`.

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.com/fogleman/sdf

One big plus to doing it this way is that it's "just" Python and you can use arbitrary logic to help construct your model.

You can even load an existing 3D mesh and operate on it as an SDF. Great for hollowing, chopping, eroding/dilating, etc. existing models.

I should probably do more with this project. I think there's a lot of interest in this space.

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 language in the brain.

And what does this even mean? What does it mean for there to be a "programming language" in the brain?
