Very happy to see this published! DGF is very similar to Nanite's encoding minus attributes. Switching Nanite to this format would be some work but is definitely possible. Doing so wouldn't be much of a win for rasterization but the really exciting part here is ray tracing it.

Really proud of what I was able to achieve developing 3D cell nuclei with custom geometry shaders using Three.js for a cancer care platform, all built with Google Gemini 3 Pro AI 💜 Had to approach the project twice, but had a lot of fun doing it :) Live:

Did you know that in Blender you can easily make insets with the 'Intersect Knife' operator? ✨ 1. Select the geometry you want to cut out 2. Press Ctrl+F,K 3. Remove the original geometry and select the newly cut faces 4. Press Ctrl+F,F to extrude along normals Important: when you're extruding faces along normals, be sure to also press S after you press Ctrl+F,F to enable the "Even Thickness" option for a better result! So the full shortcut is Ctrl+F,F,S (yes, really) #b3d

To support massive, high-fidelity worlds, our engine implements an efficient LOD strategy with a cloud transcoding system that streams meshes and textures, even on lower end mobile devices. We are expanding this framework to AI upsampling of 3D worlds from prompts. In this preview video below, with a single user prompt, our 3D upsampling technology updates the geometry and texture to transform the classic Roblox game Crossroads into a fantasy world with rich organic detail. 3/4

Claude Fable 5 has been out for a day. I already one-shotted a voxel spaceship racer with it. I fed it a reference image of a track layout and told it to build a full game around that shape. Missiles, boost zones, 3 AI opponents, 3 laps, a HUD with speed and health. Fable 5 read the image, traced the track geometry, and built the entire thing. One prompt. This is what Mythos-class models do to the build cycle.

Geometry 🤝 Topology What you're seeing here is called Hopf Fibration. In pure-math terms, S³ (the unit sphere in 4D) can be decomposed into circles called fibers. The Hopf map sends each of those circles to a single point on S². So you don’t fill S³ with random loops, you fill it with a perfectly organized family of circles, one circle sitting above each point of S². For the animation, we sample thousands of fibers on S³, apply a smooth SO(4) rotation (a real rotation in 4D, not a 3D cheat), then stereographically project into R³ so we can actually draw it. Pure mathematics is beautiful alz #HopfFibration #Topology #Geometry #StereographicProjection #PureMathematics

The Freemasons did not invent the title of Great Architect for God arbitrarily. Randall traces it to a specific and ancient understanding - that the universe was built according to geometry, that all of creation carries that geometry inherently within it, and that the role of the master builder was not to express personal creativity but to replicate the processes by which God constructed reality itself. The grand geometric mean - another name Randall notes the Freemasons apply to the divine - points to the same conclusion. Mathematics and divinity were never separate categories in this tradition. They were the same thing viewed from different angles. What Randall finds most compelling is the point at which observation overtakes skepticism. The geometry is there. It appears in the proportions of living organisms, in the structure of galaxies, in the dimensions of ancient monuments, and in the relationships between celestial bodies. Randall’s position is straightforward - there is a threshold beyond which dismissing this as coincidence is no longer intellectually honest. Once you begin looking for the geometry of creation, it becomes impossible to stop finding it. The ancient master builders understood that - and everything they built was a deliberate act of alignment with a geometric order they believed was not invented by human minds but discovered within a universe that was already built that way from the beginning.

Titanium is one of the hardest materials to machine. It cuts much slower than aluminum, runs hot, and deep bowl-like geometry will snap a tool if chips aren't continuously flushed out with coolant. That strength is what allows thin, complex parts to hold tight tolerances, making it the material of choice for high-performance satellites that have to survive the harshest environment there is. Astranis machines titanium in-house at our factory in Northern California, building world-class hardware on American soil.

Elon: "There is some chance that HW3 does not achieve the safety level that allows for unsupervised FSD. There is some chance of that. And if that turns out to be the case, we will upgrade those who bought hardware 3 FSD for free. We're going to have to upgrade people's hardware 3 computer for those that have bought Full Self-Driving. And that is the honest answer. And that's going to be painful and difficult, but we'll get it done. What we want to do is we want to get unsupervised done on Hardware 4 first. Once it's done, then we'll go back and look at what we need to do with Hardware 3 cars. Yeah, we've not completely given up on HW3, but we do want to solve autonomy first, and then we'll come back with a way to take care of customers. These customers are very important. They were the early adopters. We will definitely take care of you guys. Once the V14 release series is fully done, we are planning on working on a V14 lite version for Hardware 3, probably expected in Q2 next year"

Starting the new year without human labeling 🎉!! Multimodal lidar-camera data is a gold mine of dense 3D geometry hiding in plain sight. For supervised pretraining and validation at scale at Torc-Robotics, we rely on fully automated pseudo-labeling pipelines. Exploiting geometric priors from temporally accumulated LiDAR maps and an iterative update rule enforces joint geometric–semantic consistency while detecting moving objects via inconsistencies. We achieve 3D semantic labels and 3D bounding boxes with human-like quality at 200m+ range required for highway driving. Paper: Exciting work with Torc-Robotics with Filippo Ghilotti, Samuel Brucker, Nahku Saidy, Matteo Matteucci, Mario Bijelic.

Wow. Recreating the Shawshank Redemption prison in 3D from a single video, in real time (!) Just read the MASt3R-SLAM paper and it's pretty neat. These folks basically built a real-time dense SLAM system on top of MASt3R, which is a transformer-based neural network that can do 3d reconstruction and localization from uncalibrated image pairs. The cool part is they don't need a fixed camera model -- it just works with arbitrary cameras -- think different focal lengths, sensor sizes, even handling zooming in video (FMV drone video anyone?!). If you've done photogrammetry or played with NeRFs you know that is a HUGE deal. They've solved some tricky problems like efficient point matching and tracking, plus they've figured out how to fuse point clouds and handle loop closures in real-time. Their system runs at about 15 FPS on a 4090 and produces both camera poses and dense geometry. When they know the camera calibration, they get SOTA results across several benchmarks, but even without calibration, they still perform well. What's interesting is the approach -- most recent SLAM work has built on DROID-SLAM's architecture, but these folks went a different direction by leveraging a strong 3D reconstruction prior. Seems to give them more coherent geometry, which makes sense since that's what MASt3R was designed for. For anyone who cares about monocular SLAM and 3D reconstruction, this feels like a significant step toward plug-and-play dense SLAM without calibration headaches -- perfect for drones, robots, AR/VR -- the works!
