WebGPU particle fluids library demo with cloth and soft bodies

I promised something cool this week. Time to deliver! 🚀 Meet Three.js Particle Fluids—a WebGPU-based library for simulating fluids, rigid/soft bodies, cloth, and gases. Live demo 👉🏻 https://t.co/qL2tzSXmFk Source Code 👉🏻 https://t.co/fD9SpaPNRG What makes PBFs so special? Because *everything* is represented as particles, you can have fluids, soft-bodies and cloth in a single scene and they all collide and interact with each other. This let's you create some really cool effects that are difficult to do with other methods: - You can squirt water at a cloth and it will push back - Cloth drapes around objects - Soft bodies can float or mix into fluids You can easily tune performance across devices by modifying particle counts. I spent quite a few hours building and researching this a few months ago but it never really reached a level of quality I was happy with releasing. Fast-forward to today, I was able to leverage Opus 5.5 to get the library to a more complete state. Excited to see what people build with this!
