    A JavaScript library for data visualization in both SVG and Canvas▲161

    Here's a project I've been working on for a little while now. Ripl is a JS library that provides a unified API for rendering shapes on both canvas and SVG interchangeably. Over the years I've used D3 extensively to create data visualisations so I figured I'd have a go at making my own version with a slightly more modern API and stricter TypeScript support. I am aware there are already libraries that can draw to multiple contexts interchangeably, but I've added a few little niceties to Ripl that (as far as I know) some other libraries don't have such as CSS-like query selectors, DOM-like…

    A Node Based Editor for Three.js Shading Language (TSL)▲7

    Three.js recently introduced TSL (Three.js Shading Language), a way to write shaders in pure JavaScript/TypeScript that compiles to both GLSL and WGSL. I built this editor to provide a visual interface for the tsl ecosystem. It allows developers to prototype shaders for WebGPU/WebGL and see the results in real-time. This is a beta release and I'm looking for feedback.

    Repaint – a WebGL based website builder▲236

    Hey HN! We're Ben and Izak, founders of Repaint (YC S23). Repaint is like Figma, but for creating real websites. It has panning, zooming, and dragging elements around. The settings closely follow html/css. We think an open canvas is a big improvement over other website builders. Everything is easier: styling, consistency, responsiveness… But making it work was hard! We thought HN would appreciate the tech behind it: - A custom WebGL rendering engine (w/text, shadows, blurs, gradients, & opacity groups) - A partial implementation of the css spec - A custom text editor & text shaper…
