Proud to share the work we carried out @iconem following the ambitious 3d-scan of San Pietro Basilica, Vatican! 🎉 Incredibly grateful to our partners who made this project possible @Microsoft & La Fabbrica di @BasilicasPietro
First results on "Potree-Next", a WebGPU-based rewrite of Potree. Still work to do before it is production-ready, but over the course of the next year it will catch up with the current Potree 1.8, and eventually replace it. github.com/m-schuetz/Potr… netidee.at/potree-next
Blender Alert! 🚨 5.0 is now in Beta and already looks like one of the best updates ever. So many exciting new features and improvements to boost global adoption. Let’s dive in... A Thread👇 #b3d
Impressive deep-dive! 🔥 CLOD meshlets built in 30min @ 8 threads/192GB RAM on a 1.64B tris @glTF3D (18.9B w instancing) Available in meshoptimizer et vk_lod github.com/zeux/meshoptim… github.com/nvpro-samples/… Inspired by @BevyEngine jms55.github.io/posts/2024-06-…
New blog post! In "Billions of triangles in minutes" we'll walk through hierarchical cluster level of detail generation of, well, billions of triangles in minutes. Retweets welcome! Link in reply because algorithm.
One of my favorite things since switching to Blender, is that "coming soon" isn't really a thing anymore. Anytime a blender dev teases a feature, the community will go ahead and supplementally recreate that feature the same day, so you don't have to wait. Oh and it's free! :D
@kbgg_ probably of interest to you and source_coop! A react frontend to a federated-collection STAC API, which would basically allow representation and sharing of catalogs and datasets served from where they live, aggregated! discover.dit.maap-project.org github.com/developmentsee…
Introducing Vantor. The next chapter of Maxar Intelligence starts today. We’re on a mission to help our customers make sense of all the sensor data they collect across space, air, and ground—because building a unified intelligence picture is harder than ever. Too many sensors.…
Job update: after nearly 8 years of open source I'm excited to go independent to work on consulting & OSS dev. More details to come, but feel free to reach out about collaborations or how you can support my work! #threejs #javascript #webgl #gis #cad
Really nice Easing Editor by @JulianGarnier for animejs! animejs.com/easing-editor/
Anime.js 4.2.0 is out! 🧩 All modules can now be imported individually with subpaths 🎨 CSS variable values support 🏹 Simpler spring API with bounce & duration params 📈 More WAAPI built-in easing functions 🎛️ And an easing editor! Plus tons of fixes and improvements!
Introducing GeoVibes, similar to @EarthGenome Earth-Index, but runs locally on any embeddings! Great deep-dive: christopherren.substack.com/p/vibe-check-y… Work by Christopher Ren, Noah Golmant + @Zboknows @isaaccorley_ repo: github.com/cr458/geovibes…
NOW in Beta in Needle Engine: new features for responsive 3D and scrollytelling. Try it now and give feedback! @NeedleTools #threejs
With WebGPU, AAA graphics on the web isn’t a dream anymore. Devs just need native-grade tools. That’s why I’m building Three.js Plus. Today I added GPU culling. Here 5M PBR cubes distributed in <10ms on a convex geo, running at 120fps thanks to object culling & indirect draws.
Today’s work reminded me: tossing more OSS into the void isn’t it. Too often it fades without support. So instead, I’m putting care into how I share, bundling the code I use daily at @utsuboco into Threejs Plus: advanced, always-up-to-date WebGPU-first components. 1/4
Among other things, great Taxonomy of Camera Motion Primitives in this paper! linzhiqiu.github.io/papers/camerab…
“We must perceive to move, but we must also move to perceive.” – J.J. Gibson Humans perceive the world through movement, e.g., depth from motion parallax). Likewise, camera motion is key to understanding a video’s perspective and the intent of the “invisible” camera operator.…
My four takeaways from the Blender Conference🇳🇱 1. It's the End of an Era Ton Roosendaal (founder and CEO of Blender) will step down on Jan 2nd, but remain in a supervisory role on the board. In his place, Francesco Siddi (the current COO) will assume the title of CEO. It was…

We release a lot of demos and our model can support up to 2000 views in one inference call! Lots more features & demos incoming - stay tuned here ⭐️: github.com/facebookresear… Also don’t forget our 🤗 Demo: huggingface.co/spaces/faceboo…
WMS Tiled Image Overlays are now in 3d-tiles-renderer! This new feature, made possible by "SoftwareMechanic" on Github, unlocks a whole suite of new data, including this USGS Hydrography dataset 🌊 Demo in thread 👇 #gis #threejs #3dtiles #nasajpl #maps #webgl
🚀 Big news in the DuckDB spatial world! The DuckDB spatial extension has just added support for ST_AsMVT and ST_AsMVTGeom. This functionality will be included in DuckDB v1.4 (releasing next week 🎉). We will be able to stream vector tiles directly from DuckDB using large…
A few days ago I asked the community to share the most realistic Blender projects they had seen. The answers were incredible and full of inspiration 🤯 Here is a selection that really stood out. Scroll down and enjoy the thread 👇
here's the same example in react codesandbox.io/p/devbox/webgp… i turned the blocks into instances, should be a bit quicker to render. still hard for me to comprehend what the tsl code is doing, but the possibilities seem endless.
