I like this website a lot and used it as the base recipe book for a program that will tell you what cocktails you can make with the ingredients you have, but also what cocktails yo…

https://github.com/ianthehenry/janet-module/blob/master/init... This is a very very barebones version of this, but it’s not too hard to construct environment tables dynamically

The `import` macro extends the current environment with prefixed symbols from another environment. But the environment is a first-class object that you can hold and manipulate and …

The next chapter is about SDFs, but it is not available yet. https://www.makingsoftware.com/chapters/rays-and-sdfs

Bonsai is a frontend framework that models data as an explicit graph, separate from any “component hierarchy” or DOM structure. State can live anywhere in the application graph, wh…

I'm working on adding something like https://graphtoy.com/ to my lisp-based 3D art tool https://bauble.studio/ . It's really useful to visualize functions like this, especially whe…

If this kinda thing piqued your interest and you want to play around with this idea, paste the following code into https://bauble.studio/ : (def octaves 4) (def lacunarity 2.00) (d…

okay, that's helpful. the "undefined is not an object" bit is definitely a function of the "failed to create webgl2 context" error -- it tries to reference it unconditionally. no i…

huh, that's no good. it works fine for me on safari 18.1. would you share the line that it's raising on? no other errors before that one?

I ordered them from sculpteo — the only service I could find that would do it. Very happy with everything I’ve gotten from them. It is very very expensive if you want to make anyth…

It's complicated; Calvin Rose was the original creator of Fennel ("fnl"), but I understand it was just a little side project that he made over the course of a week or so in college…

hi, i am the author of this book and i agree with you. it's not a good connotation. i chose it because: 1. it is kinda memorable (look there are so many programming books with exac…

delete the contents of the script and then refresh — you’ve loaded an old version of bauble before and have the old tutorial cached in localStorage :/

hey thanks!

Thanks! Here's the source: (color r2 (vec3 (fbm 8 :f (fn [q] (rotate (q * 2) (pi * sin (t / 100)) + [t 0])) (fn [q] (cos q.x + sin q.y /)) q (osc t 30 30 10) | remap+))) Basically …

Oh yeah if you clear localStorage like from dev tools, Bauble will re-save the script before refresh, putting it right back where it was. But if you like cmd-a backspace to empty t…

Depending on the data, maybe? SDFs aren't great at rendering large numbers of enumerated objects -- something like a point cloud would be prohibitively expensive, so I wouldn't thi…

So if you've ever loaded Bauble before you might have a stale and no-longer-working version of the tutorial cached in localStorage -- if you just clear out the script and refresh i…

oh yeah good point. i probably shouldn't link to that anymore. it's all on mastodon too! https://mastodon.social/@ianthehenry

https://bauble.studio/ is a programmatic 3D art playground that I've been working on for a while now, and I'm pretty excited about it! It's based around signed distance functions, …

Yep! It just outputs GLSL. It doesn't do anything smart -- it's a single giant shader that gets recompiled whenever you change anything, so it wouldn't really work for something li…

https://bauble.studio/ is a lisp-based procedural 3D art playground that I hacked together a while ago. It's fun to play with, but it's a very limiting tool: you can do a lot to co…

Ah, thanks! Got it. Okay that's wild. I would not expect that to be stable across dynamically-generated template functions, but it seems to work!
