• commands

  7 21 6.1 TypeScript

  Collection of editing commands for the CodeMirror code editor

  

It's CodeMirror! All I had to do was write a Janet grammar for it -- very easy to do. CodeMirror is pretty amazing -- I was able to implement the "edit values with your mouse" by just asking CodeMirror for the syntax node under the cursor, checking if it parsed as a number, and if so replacing it with a different string.

I went with CodeMirror after reading this post that compares a few different editor components: https://blog.replit.com/codemirror and I've been super happy with it.

• glicol

  132 1,988 8.0 Rust

  Graph-oriented live coding language and music/audio DSP library written in Rust

For IDE, you can use the combo (Vite.js, Sevelte.js, and Windi CSS) I choose for building Glicol (https://glicol.org).

I had a blog post about the combo before:

  Infrastructure for solid modeling

  

No; Bauble doesn't know how to "rasterize" SDFs into meshes; it only knows how to raymarch them. It's theoretically possible, but it's a pretty complex problem that would take me much too long to figure out and implement. So Bauble is relegated to just making pretty pictures for now. If you want to produce meshes using SDFs, check out https://libfive.com/

• retrace.gl

  1 189 0.0 JavaScript

  Create, ray trace & export programatically defined Signed Distance Function CSG geometries with an API suited for generative art - in your browser! 🎉

I've written a tool somewhat similar that can export meshes of sdf's created using a javascript api, check it out: https://github.com/stasilo/retrace.gl

• colorchord

  7 656 1.8 C

  Chromatic Sound to Light Conversion System

• audiolink

  Audio reactive prefabs for VRChat

• InfluxDB

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• implicit

  4 1,285 8.6 Haskell

  A math-inspired CAD program in haskell. CSG, bevels, and shells; 2D & 3D geometry; 2D gcode generation...

  

There's also ImplicitCAD (https://github.com/Haskell-Things/ImplicitCAD) which produces STLs, as it is designed for CAD. It uses implicit functions, which I believe are similar to SDFs (I believe the idea is not to necessarily correspond to the distance function).
