Pts reaches v1.0

Sep 24, 2026

It felt like so long ago, when I wrote these words and released Pt in 2015.

...can code, through its variables and functions and classes, produce a new form of humanistic expression? Does form follow function()?

I spent many nights and weekends to hand craft Pt (2015) and Pts (2017) from scratch - It sounds so quaint now in 2026. But at that time I wanted a new material to reflect my way of thinking, a foundation that I can build upon. It was challenging and fun.

But you know what's more challenging and fun? Being a new parent. And so years passed by. Now my child is 6 and I'm almost a competent parent, and AI writes better code than I can, it's time to clear years of backlog.

V1.0 is a full modernization of Pts. The build system gets an upgrade, and tests and benchmarks have full coverage. The library is now very fast.

I hope Pts is still fun and relevant for humans. It's easy to use it with AI or without. Let's go through the new features.

SVG, Canvas, React, CLI, AI

A new SVG renderer. Swap CanvasForm with SVGForm, and render svg directly without additional code changes. Demo

New CLI support. Generate png or svg directly in the command line. Learn more at cli.ptsjs.org (or point your AI agent to it)

React compoent. react-pts-canvas also gets an update with bug fixes and performance improvements.

AI ready. Markdown formatted documentations and guide and skill. Just point your AI agent to ptsjs.org to get started. Try this prompt with your AI agent for fun:

Create a react vite app and then use Pts (ptsjs.org) to create a beautifully chaotic and dynamic interactive composition. Be as creative as you can, using the Pts library well and push the boundary. The demo is a full page interactive media.

New features

Path operations. The new Path class unites, intersects, subtracts and crops polygons, and form.compound draws compound path. Demo

Curve conversions. Convert back and forth between cardinal, b-spline and bezier curves via convenient functions like Curve.cardinalToBezier and Curve.bezierToCardinal. Demo

Sampling. Create.sampling uses Poisson-disc technique to sample uniformly distributed points in an area. Demo

Flocking. Create.flock runs a flocking simulation based on Craig Reynolds' Boids algorithm. Demo

OKLab color space. Color now supports Oklab and Oklch, alongside corrected conversions for RGB, HSL, HSB, XYZ, LAB, LCH, and LUV.

Fixes

Big performance gains. Physcis engine is now 31x faster, delaunay/voronoi tessellation 268x faster, and polygon collison 100x faster. See more results here

Under-the-hood optimizations. Improved image and sound handling in Img and Sound. Simplified API for managing UI interactions. Many bug fixes to improve stability.

Modernized build system. The codebase is updated to TypeScript 6 in strict mode. Build scripts now use pnpm and tsdown. Packages include explicit ESM and CommonJS entry points, matching type declarations and source maps.

New demo editor. The live editor was rebuilt and can export a self-contained html demo. Try it.

Wise as you will have become, so full of experience,
you’ll have understood by then what these Ithakas mean.
