Make 3D art in your browser using Lisp and math
Bauble is a toy that I've been working on for a few weeks, and I think it's reached the point where other people could have fun with it! Bauble is based on raymarching signed distance functions, which are kind of like... 3D vector art? They're pretty common in the procedural art community and you can do some amazing things with them, but normally writing SDFs means writing low-level shader code. I wanted to play with SDFs, but I found it very frustrating to translate "I want to rotate this" into "okay, that means I have to construct a rotation matrix, and then apply it to the current point,…

In plain words
Bauble is a browser-based tool for creating 3D art using Lisp and mathematical functions. It simplifies the process of working with signed distance functions—a technique used in procedural art—by providing a high-level programming language that compiles to shader code, eliminating the need to manually write complex low-level graphics code. The tool is designed for artists and developers interested in creating mathematically-defined 3D shapes and procedural artwork.

Hi HN! 2d spritesheets for game development are often distributed as a PNG image, sometimes with a separate JSON or XML metadata document describing the layout, including any animation sequences within the sheet. Sometimes there is no metadata document and you have to work it out and manually write custom code to chop up the spritesheet and reference the sprites you want. I think it would be good if it became standard practice to distribute spritesheet PNGs with the metadata inline inside a PNG "chunk" so the whole thing is self-contained. That way artists can just distribute one file, and…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
