Crush a coliseum w/ your bare hands 🏟️ #WebGPU + #WebXR physics stress tests on Apple Vision Pro 12k bricks, 100 ragdolls, rope & cloth Based on @juretriglav.bsky.social's work on AVBD (rec'd by @codybennett.bsky.social). The scale is amazing + little-to-no clipping. Fun to play w/ on next gen h/w

Enjoy a slice of hand-chopped physics jelly 🪼 Gel, water & sand simulation running on Apple Vision Pro #WebXR + #WebGPU via three.js  Thinking about game mechanics w/ this stuff Try here - fwiw I've only tested on desktop & M5 AVP visionOS developer beta 27 jameskane05.github.io/kora-fire-th...

Another hotfix from @cabanier.bsky.social & I've got three.js #WebGPU + #WebXR running on Apple Vision Pro M5 Testing w/ real-time voxel flame sim w/ compute shader solver based on @wetafxofficial.bsky.social's new SIGGRAPH paper M5 has the horsepower to do v cool stuff in XR w/ WebGPU 🔥 More soon

Free afternoon in SF before World Labs hack-a-thon tomorrow. Good buildings, beer and weather in this town. Very happy to be here

!!!!

Watch your six! Soon I'll launch STARSPEED: Zero-G Aerial Combat in partnership with WorldLabs.ai 🚀 Multiplayer & campaign inspired by Descent/DOOM w/ a gripping story & synthwave OST 🎹 Here's a peek at the making-of w/ SparkJS + three.js -- early access is days away!

New post on how to do real-time diffuse global illumination using surfels and #WebGPU: juretriglav.si/surfel-based... #threejs

New game approved! It's such a banger. Cross-platform but will be killer in XR, single & multiplayer, building in public. Real announcement soon! In the pipe, five-by-five 🚀

My #WebXR + #WebGPU demo got picked up by 80 Level! More to come, especially as three.js adds support 80.lv/articles/esc...

@toji.dev I'm trying to hook up WebGPU on WebXR in three.js using my Galaxy XR. The first frame always comes in with a null XRFame. Is that a known issue? Also, the browser doesn't always show the immersive scene even though I'm producing frames.

Blast from the past to start the day. That the number one children's show for years on end was detective-themed is... interesting to me personally www.youtube.com/watch?v=OVVk...

My new game launches this week Don't let it sneak up on you

Don’t ask

Gaussian splats are the connecting thread everywhere. Meta doing room scans. Apple doing Personas and spatial scenes. Closing in on reality being scanned in

Yeah okay I'm back to wanting one www.apple.com/newsroom/202...

New game announcement soon! It'll be desktop/mobile-only at launch for a change, but of course I had to develop a mixed reality "stunt capture app" for it using WebXR 🤷 Check out that process along w/ a sneak peak of my next original title, and keep an eye out for more 🏃‍➡️↗️➡️↘️🛏️

After two days at Meta Connect, where I tried on the new Meta Ray-Ban Display, I visited the Computer History Museum and saw relics like the first mouse and keyboard and the first web server. Just a few decades of steady, incremental progress separate these devices. Play the long game.

Pretty cool to walk around the Saint Louis Zoo’s free 90-acre campus and see users and signs for the one-of-a-kind 3D web map with search and GPS navigation that I architected, built and sold to this client using open source web tech - check it out: map.stlzoo.org

Meta says browser use in headset is up 28%

I'm heading to Meta Connect! Last year the game I directed was featured in the keynote and WebXR sessions. Will 'In Tirol' be recognized this year? Stay tuned, and let me know if you'll be in town!

Cool to see WebGPU demos on iOS Safari without a flag! This is still beta but should ship widely next week. Considering Apple didn’t ship WebGL 2.0 until like 2021, this is great to see Last barrier to me using it in production is the WebXR-to-WebGPU bindings, which I believe is in proposal phase?

📡 We’re looking for a freelance mid-senior level Character Animator / Technical Artist to help bring a digital character to life across a series of VR prototypes, developed in Unity for Quest. Remote OK. Recommendations and signal boosts welcomed! #XRJobs liquidcity.notion.site/Character-An...

I actually love this b/c it’s only going to demonstrate that even with pro writing, a real production schedule and a legitimate Hollywood budget, this shit is still going to suck

This has been my feeling for a couple years: LLMs are at or near their ceiling for capabilities, and will not improve dramatically from here, for reasons technical, practical, legal and economic. Recent evidence: arxiv.org/abs/2507.19703

My game "Grappler's Gauntlet" is now live on @viverse.com! Use your grappling gun to pull yourself up to the top before anyone else can stop you! You can play now at worlds.viverse.com/QTrnrXw and join the Discord at discord.gg/ccWHZtBXpA.

My keyboard has a tiny LED screen to display gifs and other info and it is admittedly dumb but also makes me happy The overall look reminds me of my old DOS Tandy from the early 90’s, which is to say 🥵 www.amazon.com/dp/B0BZCMX4R...

I'll be at Meta Connect in SF from Sept 16-20 talking #WebXR to anyone who'll listen, hope to see you there

📢 Meta published my guest piece on their developer blog! I wrote about making ‘In Tirol’ as a one-man band, including inspiration, script, art, score, voiceover, development and launch at GDC: developers.meta.com/horizon/blog...

Cool to see Vienna among the top cities playing In Tirol globally each week

My Voices of VR interview is out! I spoke to @kentbye.com at @awexr.com about my game, WebXR broadly, and publishing on @viverse.com. I'm a huge fan of this podcast b/c of Kent's journalistic objectivity and ethics, but also his genuine enthusiasm and deep experience voicesofvr.com/1615-viverse...

I published 41 interviews from 2018 to 2025 on the Voices of VR covering Augmented World Expo Past & Present. I cover XR & AI like a hyperobject over space & time through the modality of oral history, and this series is 24.5 hours long spanning lots of topics. See my cheat sheet with tags & metadata

Github Repo: github.com/pmndrs/viverse Docs: pmndrs.github.io/viverse/ Super excited for this launch since it enables every threejs dev to get started with VIVERSE! Let's show them the power of the threejs community ❤️

Introducing pmndrs/viverse and react-three/viverse 🎉 A Toolkit for building @threejs.org and React Three Fiber Apps for VIVERSE and beyond with only a few lines of code ⟁

Art and inspiration for In Tirol

The PWA in-app purchases discussed here is a step in the right direction, but very glad @uploadvr.com captured this perspective. Meta Quest and its browser needs a trusted OS-level wallet for it to move beyond niche gaming console status

My cat Lucy is always mad in the morning before the sun comes down the wall. I think she thinks I control all light in the world so she sits there and meows at me

I am *this close* 🤏 to finishing Quest 2 optimizations for In Tirol and writing a blog post for Meta's developer blog on the making-of. Similar to my piece on Above Par: developers.meta.com/horizon/blog... Release cycle almost done. Eager to move on to the next thing but this is part of the work

WebXR apps packaged as PWAs on the Meta Horizon Store can now use in-app payments, letting web developers monetize their experiences:

Inching toward a key feature for intirol.game but Meta had a bad month for reliability. OS bugs mean WebXR entry/re-entry randomly stalls, controllers won't render, & the home env locks up on session end. Respect to their teams, this stack is monumentally complex, but I'm eagerly awaiting a hotfix!

Proud to share: VIVERSE now supports all major WebXR engines (Unity, Godot, Three.js & more). Also live: VIVERSE Studio 📦 World management 🚀 Easy deployment 📊 Analytics 👤 Custom profiles 🔗 Watch, then visit news.viverse.com/ for more info! #WebXR #GameDev #VIVERSE

For a while now any time family asks me about AI my default response has been "It's a bubble now, but all it's going to take for some big IP holder, like Disney, to win a copyright lawsuit and the whole thing becomes one giant liability." And, welp...

I posted a small description on Quest browser new experimental "shared spaces" feature: github.com/cabanier/sha... Here's a small demo recording that show it in action:
