✨ Glyph v0.1.0 coming out party ✨ The typography engine for the web. Finally, text that looks like it came from a native app in your web pipeline. → gpu-first with batched drawing and incremental updates → bitmap, mtsdf and slug in one engine → correct multilingual text, shaping, bidi, cjk, ligatures, font fallback → paragraphs that wrap, justify, flow around shapes and 3d objects → one font pipeline for three.js, R3F, typegpu or your own renderer github.com/pmndrs/glyph

We have been working so hard on this Advanced R3F workshop and want teach you everything we know about scalable 3D apps and the future of TSL, WebGPU and R3F v10. It is coming to @threejsconf in less than a week. If you are in Paris on the 8th and 9th, check us out. Here is a peek at everything you will build from a (legally generic) voxel game to a product configurator to a website hero. We have limited spots so reach out if you want to join. ➡️Sign up here: threejs.paris/workshop 📷 Learn more: r3f.paris

an idea i recently played with: gracefully suspend a webgpu scene when the browser becomes inactive - animations ease to a halt - lights are dimmed - the render loop pauses on the final frame the scene then comes back to life on focus :) → r3f.maximeheckel.com/webgpu/…

✈️ Our advanced React Three Fiber workshop is happening Sept 8 & 9 at @threejsconf and it is FOUR workshops in one. You get to preview R3F v10, our new tech stack and walk away with a cool app of your choice. 👉 r3f.paris/ Day 1: Learn the full R3F v10 WebGPU stack from staging to reactivity to TSL and postprocessing. We'll break down the Paris hero and more. Day 2: Build something amazing. Choose between a game, product editor or creative portfolio or even all three if you are ambitious enough. Each tract is headed by one our pros: ✧ @DennisSmolek: Author of R3F v10 and more at Poimandres. ✧ Kris Baumgartner: Organizer, Koota author, and general maintainer at Poimandres. ✧ @CantBeFaras: Senior graphics programmer, technical artist, and maintainer at Poimandres. ✧ And supported by Poimandres dev Ava Lehner. A great amount of work has gone into this and we are excited to make something special with you in Paris. Sign up here: threejs.paris/workshop

React Three Fiber and the broader pmndrs ecosystem inspired for years with beautiful example drops by @0xca0a, @CantBeFaraz and more. These were historically hosted on CodeSandbox, rest in peace, and soon rotted with the rapid demise of these services. Well it's back. 👉 pmndrs.github.io/examples/de… 👉 github.com/pmndrs/examples Not every example is 100% complete but full conversions are in progress. Included is metadata cataloging authorship, data, libraries and more. Check out the archives!

Pmndrs is an open source dev collective, but it hasn't always been clear what that means. We are going through a lot of changes right now as part of that journey and I want to bring you along. It all starts with our mission: "Poimandres is an open source developer collective for creative technology and developer tooling. We make things for people who make things because we believe code can be a craft, a creative medium, and a source of joy. Our projects are sustained through shared effort, mutual support, and trust." Followed by our core principles: simplicity, pragmatism, stability and quality. These have stayed consistent from the beginning pmndrs over 8 years ago! So what is changing? Before we were a self-organized group of developers with a shared passion and commitment, but this ran its course as people's priorities changed and passions moved elsewhere. On top of this, sometimes members would be working the same idea in parallel or having competing interests. To keep pmndrs and its current and future libraries healthy we needed to seriously organize, align on priorities and direct resources. The process strives to stay true to our principles by being in the open. As we get work done in practice and it feels good, we talk it over and then add it to our charter. The goal is document how we want to work not tell people how to work. You can find a link to the draft charter below. It is shorter than you might think! To align priorities and communicate with our users we started adopting what we call initiatives. From the charter: "The collective may adopt initiatives to set priorities, allocate collective resources, and align work toward the collective’s mission. An initiative has a definite goal and should not be intended to last indefinitely. An initiative must have a lead dev to be accepted." Our current active initiatives are: ▪️React Three Fiber v10 ▪️Text rendering ▪️A pmndrs design system With two in draft: ▪️Devtools framework + controls (Leva 2) ▪️The world's best spatial math library And most importantly we are working in the open on all these initiatives and more on our Discord and Github. Join us on both! Our commitments to our values, joy and each other is what makes this work. That work covers the intersection of great engineering and great design and always open source. We believe technology should be for creativity and joy and while we can't control how it is used, we strive to promote how we think it should be used. Everyone is invited to get involved and help us build open source.
