Happy to report that Lego LDraw models are working #threejs #raytracing #webgpu #lego

Per-instance color support 🫧

Using the recently-added "ObjectBVH", geometry instancing is also now supported. So complex scenes like these can finally be rendered without merging it all into a single geometry ✨ #threejs #raytracing #javascript #webgpu

Environment map sampling & backgrounds are now supported in the WebGPU path tracer! Slowly but surely we're getting features ported over. Thanks to "TheBlek" for getting this added! #threejs #webgpu #javascript #raytracing

We have a first pass at a wavefront path tracer! You can see the artifacts of thread groups pulling rays off the ring queue to trace in this slowed down video. It's not much, yet, but Im excited for what this will bring in terms of performance scalability✨ #threejs #raytracing

Spent some time today looking into WebGPU support for three-gpu-pathtracer - compute is going to make this a lot easier than WebGL. Looking into Wavefront Pathtracing next ✨ Thanks to "TheBlek" on Github for helping to get this started! #threejs #raytracing

I revisited my parallel IK system for the first time in awhile to make some ergonomic improvements & got perf improved by over 50% in some cases 🦾🤖 I still have some more improvements in mind, though, when I have some more time. Repo link below 👇 #threejs #webgl #robotics

Some amazing work by Jure Triglav putting WebGPU compute and three-mesh-bvh through their paces to render surfel-based global illumination! I'm looking forward to seeing what's coming in the web in the coming years. juretriglav.si/surfel-based... #threejs #raytracing #webgpu

User "web3d" over on the threejs forums using 3d-tiles-renderer to display some awesome drone scan data processed into tiles 🗺️ #threejs #gis #3dtiles

Using the same scene-wide BVH you can run accelerate frustum culling, as well. With this 500,000-instance BatchedMesh culling runs in less than 1/8th the time 🚀 #threejs #gamedev

With the recent three-mesh-bvh changes you can finally make a full scene-wide BVH to accelerate physics, raycasting, etc. And at some point Pathtracing 😁 Its just a prototype so far but it "just works" with objects and batched instances in a single structure. #threejs #gamedev

With the new abstractions in three-mesh-bvh, making a custom BVH is easier than ever! SkinnedMeshes can now have one created directly, leading to an over 2x perf improvement on update vs creating a new static mesh. 🚀 What else needs a BVH? 1/2 👇 #threejs #webgl #gamedev

It's been a long time coming but the latest version of three-mesh-bvh brings support for out-of-the-box Line & Point cloud BVH support! Now all your geometries can be fast 🚀 1/3 #threejs #webgl #javascript

Last year I was also experimenting with @gkjohnson.bsky.social's blue noise sketches, but with my usual subsurface scattering and motion blur. alien.js.org/examples/thr... #threejs #webgl #shader #bluenoise #motionblur

Im seeing a difference in behavior with deployed code on @github.com pages vs the same files locally. Has anyone seen this before? Left is edge generation run locally & right is on Github pages from one of my #threejs projects. Notice the extra lines. 1/3 👇 #webgl #javascript

Thanks to amazing work from "SoftwareMechanic" on Github, the 3DTilesRendererJS project now supports GeoJSON overlays! Perfect for draping GIS datasets - region outlines, property boundaries, or GPS paths - onto any 3D Tiles data set 🗺️✨ #threejs #gis #3dtiles #maps #javascript

More graphic screenspace SDF effects 🐔🤖 #threejs #webgl #gamedev #realtimeVFX #javascript

Taking a dive into Bezier curves for fast SVG & font rendering. The curves are evaluated in a fragment shader so they're resolution independent with single-pass antialiasing📈 Cubic curves next! Though it looks a bit more complicated... #threejs #webgl #gamedev #javascript #svg

Here's the blooper version I mentioned. (I have no idea who the uploader is or how they got a copy of this. But I am glad that it survives.)

Thanks to @mrdoob.com, three-gpu-pathtracer now includes a drag-and-drop viewer for binary glTF files 🚀 I've added a link to the viewer in the repo! #threejs #webgl #raytracing

These are some of the more basic effects you can make, I think, but these are outline & glow effects made with the Jump Flood SDF buffer - link to the repo below! 👇 #threejs #webgl #gamedev

Back from some time off programming with a Jump Flood Algorith demo to ease back in! JFA can be used to create a screen SDF from a model in real time - useful for things like silhouette outlines or any other visual effects. More effects coming up! ✨ #threejs #webgl #gamedev

Version 0.9.2 of three-mesh-bvh is out now and brings support for raycasting & distance queries using WebGPU compute shaders! This is the first step towards WebGPU path tracing & other compute-shader features 🚀✨ #threejs #webgpu #javascript

What are your favorite examples of documentation out there, especially for 3d libraries? What do they do well or not well? I'm considering updating some of my project docs & am looking for inspiration. Even the little things make a difference. #threejs #webgl #javascript

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

3d-tiles-renderer & atmospheric rendering spotted in this "Air Fiesta" hot air balloon adventure experience online! Posted by Diego_Dotta on the threejs forums 🪂 Link to the post below 👇 #3dtiles #threejs #webgl #javascript

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

3d-tiles-renderer has been gaining some real momentum this year. The number of weekly downloads has more than doubled since January to well over 7000 installs per week! 🌎✨ Sometimes I wish I knew more about where they were all coming from 😅 #gis #3dtiles #webgl #threejs

The "3d-tiles" renderer is slowly becoming "any tiled data" renderer - newly added support for WMTS tiled images brings a whole new world of mapping data to #threejs. Including the massive catalogue of data from NASA GIBS! Demo below 👇 #webgl #gis #3dtiles #nasajpl #nasa

Looks like CesiumJS just released a new Martian data set on Cesium Ion! Controls and rendering work out-of-the-box with 3d-tiles-renderer, as well. Mars rover integration coming... someday? 🤖 Demo link below 👇 #threejs #webgl #gis #nasajpl #3dtiles

I was doing some debugging on 3d tiles with a red color ramp & tone mapping enabled and accidentally lit Mars on fire.

I've just gotten support added for starting a session & loading Google Maps map tiles with NASA-AMMOS/3DTilesRendererJS -- now you'll be able to load Google maps street & satellite data in three.js. Now I have to find time to make demos 😅 🗺️🛰️✨ #threejs #webgl #maps #3dtiles

3DTilesRenderer now supports multiple tiled image overlays with different projections and per-layer tint & opacity. This video is showing a globe base layer & Washington DC overlay layer from Cesium Ion. Planar projection coming up next! #gis #3dtiles #cesiumgrant #threejs

3DTilesRendererJS now has initial support for TMS & XYZ tiled overlays on 3d tile sets, bringing more support for CesiumJS's terrain features. This demo is using the Swiss Alps Quantized Mesh data set w/ @openstreetmap.bsky.social images 🌎🌐 1 / 2 👇 #cesiumgrant #threejs #gis #3dtiles

Some new updates to QuantizedMesh support for 3d-tiles-renderer. The spec for available tiles is now completely supported and tile gaps are now filled in by clipping the parent tile into quadrants! Texture overlays are next. 1/2 🌎 #threejs #cesium #3dtiles #gis #cesiumgrant

I’ve used three-gpu-pathtracer by @gkjohnson.bsky.social to create an online demonstration featuring optical prisms. The result is mindblowing, accurately capturing the multiple reflections and refractions of real-world optical elements. 🔗 Explore it on GitHub: cyamahat.github.io/three-gpu-pa...

I've gotten contour and latitude / longitude lines working with ellipsoidal tile sets in 3D Tiles Renderer - demo link below! 🌎✨ #threejs #webgl #3dtiles #gis #cesiumgrant

Slow but sure updates on the topo line shader: the plugin can also be used to render an infinite grid, as well. The logic for contour lines & grid lines are nearly the same - they're just being scaled differently in this case 🌎📏 #threejs #gis #3dtiles #cesiumgrant #webgl

My three-geojson repo now supports internal polygon vertices via constrained delaunay triangulation so extruded shapes can be projected onto an ellipsoid surface with generated smooth normals! 🌎 More below👇 1/3 #threejs #gis #javascript #webgl

I finally got around to writing GeoJSON parser for threejs. It supports triangulating & extruding polygons, and projecting all GeoJSON types onto an ellipsoid for integration with projects like 3d tiles! 🌎 Repo with demo links below 👇 #threejs #gis #3dtiles #webgl #javascript

Heres a project I wrote a previous version of the contour shader for from 4 or 5 years go at #NASAJPL. This tool is used for auto drive planning, testing, & inspection and is still used to operate & understand rover drives on Mars. More info below 👇 #threejs #webgl #javascript

How does ROLLBACK NETCODE work, why is it so difficult to program, and why is it the gold standard for fighting games? A whirlwind tour of different solutions #pixelart #gamedev #AnimationVERSUS The setup: you have a video game with couch co-op and want to add online multiplayer. Easy, right...? 🧵

A fun render I came across while adding topographic lines to Google Photorealistic Tiles. The topographic lines are computed relative to the earth ellipsoid which results in circular patterns due to the low res vertex undulation on the surface 🌐✨ #threejs #gis #3dtiles #webgl

I came across an article that included a video of one of the last projects I worked on while at #NASAJPL for understanding & debugging the Mars Rover's autonomous driving system. This is how the rover sees the world while driving - article in comment!👇 #webgl #javascript #threejs

This is the 5th or 6th time I've written a topography shader & every time it gets a little bit better & I learn a little bit more. It's a nice challenge for anyone learning about shaders! Some details on the plans for this implementation below 👇 #gis #3dtiles #threejs #webgl

QuantizedMesh support has been added to 3DTilesRenderer thanks to another grant from Cesium! The plugin supports normals, water masks, tile skirts, & "just works" with Cesium Ion. Support for texture overlays in progress! 🌎✨ #threejs #3dtiles #javascript #gis #nasajpl

Have we already talked about the @threejs.org cameo in Donkey Kong?

What kinds of devices, specs, bandwidth do you target / test web experiences on to reach the widest international audience possible? I want to develop a #threejs app & make sure it will work as widely as possible including html fallbacks if necessary. #webgl #webgpu #javascript

With #LPSC2025 about to start, it's time to share what I've been working on during the last months and will be presenting at the conference. This is a new high resolution 3D model of the Mont Mercou outcrop in Gale crater, that I made during my recent internship at LPG Nantes. #planetsci 🧵
