I've added a new 3D smoke render mode to my #WebGPU Fluid Simulation. It's not an easy task to keep the best performance & quality when using a volume renderer on top of a fluid simulation, so lighting artifacts may appear if 3d enabled. Try it yourself!

For my 3d simulation I needed to implement new rendering. To replace "sphere par particle" with marching cubes. I never implemented that kind of stuff, so I decided to first try a simplified 2d version, the marching squares. It worked, very fast rendering now.

Elon Musk: If simulation theory is correct, the most interesting outcome is the most likely. Because simulations that are not interesting will be terminated. Just like in this version of reality, on this layer of reality, when a simulation goes in a boring direction, we stop spending effort on it. We terminate the boring simulation. I have a theory here. If simulation theory is correct, then there’s a tendency toward interesting outcomes. Because in this reality, when something is boring, we don’t keep paying for it. We stop the simulation. The boring ones don’t survive. As long as they’re interesting, they’ll keep paying the bills. Whatever the equivalent is of the cosmic AWS bill that this reality is running on, if things remain interesting enough, they’ll keep paying to keep it running.

Claude and I got a live sodium atom simulation! lightcell energy 🔆 I've long wanted to be able to visualize what is really happening when a neutral sodium atom is excited in a flame or a bulb. Classical theory teaches that the single outer electron orbits the nucleus and full shells, and forms a dipole when this gets "wanged" but, physicists have long wondered, what does it look like when the electron gets wanged? is it like ringing a bell? i thought that this was the perfect time to really push what is capable of, in terms of building artifacts. grabbed zig to compile wasm and webgpu to make it super performant, and work with it for a bit and ran the REAL TIME-DEPENDENT Schrödinger equation on a 3D grid in a potential in the browser. and you can kick it! what!! it's soo beautiful... this is going on the website overhaul for sure here is the artifact. i don't endorse that it's exactly right, but i feel it is probably spiritually a good sodium simulation. it certainly rings my dipole!

This was way too easy... I created a cute 3D character in minutes instead of hours using this combo: Unbound + Tripo I’m not a 3D artist, but this made the whole process feel simple, playful, and actually accessible. Unbound helped me shape the character idea, then Tripo turned it into a 3D model without the usual complicated workflow If you are a 3D artist or you are just starting, try Unbound. It’s free, open for everyone to experiment with, and a fun way to create characters, creatures, and 3D models without feeling overwhelmed I had so much fun using it today, and I think many visual creators are going to love it.

Still working on wind simulation for my standard shader. I've decided to go with a simpler texture-based approach, and I think it looks a lot better! It's amazing how much of a difference a bit of movement makes. Aiming to release this in an update soon!

🚀 I'm launching r3f-webgpu-perf today! "npm i r3f-webgpu-perf" One thing I missed while working with WebGPU in React Three Fiber was a performance monitor similar to r3f-perf. The existing tool is fantastic, but it doesn’t support the WebGPU renderer yet. So I decided to build one. ✅ Supports both WebGL and WebGPU ✅ Modern and customizable UI ✅ Lightweight and easy to integrate ✅ Built specifically for React Three Fiber My goal is to turn r3f-webgpu-perf into more than just a metrics dashboard. I want it to become a learning tool that provides real-time optimization suggestions based on the techniques I’ve developed while building hundreds of interactive 3D projects over the last two decades. A vanilla Three.js version is also planned. If you’re building with Three.js, React Three Fiber, or WebGPU, I’d love for you to try it and share your feedback. ⭐ GitHub: 📦 NPM: Every GitHub star helps make the tool better for the entire community. #threejs #creativecoding #webgpu #r3f

Excited to share that our paper 🌊🤺 “CFC: Simulating Character–Fluid Coupling using a Two-Level World Model” has been accepted to #SIGGRAPHASIA2025! In this work, we build a two-level world model (neural physics) for rigid-body–fluid interaction and use it to train physics-based character controllers efficiently. We study: (1) learning to model highly dynamic fluid environments, (2) representing character–fluid interaction via joint-level forces as an interface, and (3) enabling supervised policy learning on the learned world model—avoiding expensive fluid simulation in the training loop. Our talk is on Monday afternoon(Dec 15)—hope to see you there! Time: Monday, 15 December 2025 5:02pm - 5:13pm GMT+8 Location: Meeting Room S221, Level 2. #SIGGRAPHASIA #SIGGRAPH

Gave Gemini 3 Deep Think an image of a 3D spider web and asked for an interactive design tool. It generated a full design suite (procedural control, simulation, optimization) with STL export capability. I used it to engineer new metamaterials and a spider-web inspired bridge design, 3D printed it, then validated the structural integrity with a NVIDIA DGX Spark load test. A mind-blowing example of the future of material and architecture design - image in, fabrication-ready design out! Google Gemini

🌊 GTA 6 will take liquid simulation to a whole new level. Rockstar is reportedly using fully dynamic fluid physics, calculated in real time — not just animations or pre-baked effects like in most open-world games. That means: • Water will react naturally to wind, waves and storms • Liquids will flow, splash and deform based on collisions • Objects falling into water will displace it physically • Puddles, floods and wet surfaces will evolve dynamically • Drinks, blood, gasoline and more will move like real liquids All of this inside a massive, open, living world. 🤯🔥 This tech could drastically change gameplay in a tropical map like Miami / Vice City — storms, hurricanes, beaches, boats… everything becomes more immersive and unpredictable. And just imagine the details indoors: Glasses pouring realistically, liquid containers that actually react to motion, bars feeling truly alive… 🍻 To have some fun with the idea, I tried creating a GTA 6-style beer using 3D tools. Let’s just say… it’s far from Rockstar level 😅 I have zero experience in fluid simulation or 3D animation, so please be kind! 📸 Fan-made concept only — nothing here is official. How crazy do you think Rockstar’s fluid system will be? 👀🌴 #GTA6 #GTAVI #RockstarGames #NextGenPhysics #FluidSimulation #GameTech #ViceCity

Live: Source: You can download this to start your scenes with #r3f, #threejs WebGPU Renderer, and Post-Processing using #tsl. I also converted my jet engine shader from GLSL to TSL using the transpiler. It works like a dream😍. I added the Royal Naboo starship in the scene to show how Screen Space Reflections reacts to all metallic surfaces, not just the floor. I hope you like it. Please give me a star⭐️on GitHub if you can. #threejsJourney

SimReady assets generated from a simple prompt! No 3D artist needed. Last week at SIGGRAPH, Lightwheel launched SimReadyGen - an agentic SimReady asset generator. Since then, our team has been improving the experience, including an in browser asset viewer. I recorded this quick video to give you a peek of what the generator looks like. Want to give it a try? You an access it today at #PhysicalAI #Simulation

Robot simulation is getting a big upgrade! 🔥 Normally, building a simulation environment, a kitchen, warehouse, office takes days or weeks. You have to model the geometry, add textures, set lighting, generate collision meshes… all before a robot can even interact with it. Marble by World Labs removes most of that work. You type a text prompt or give it an image, and it generates a full 3D scene with depth, lighting, and a collider mesh you can export into engines like MuJoCo. That means researchers can quickly create lots of different environments to train robots on, which is exactly what domain randomization needs. If we want robots to learn faster, we need to create worlds faster. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →
