As promised, a (mostly) beginner-friendly thread on how to code simple physical simulations like those I've been posting recently.

Particle toy experiment, motion blur is simulated by stretching particles along their velocity in the vertex shader. Cheap trick but worked surprisingly well! (WebGL, three.js, TypeScript)

Helped someone on Reddit to figure out a site made by C2 Montréal. An interesting mix of HTML & WebGL blend modes i haven't seen explored before. Then i figured we still need to announce R3F V9. Wanted to make sth big but let's do that for v10. ↓ What's new in v9

Now we can create 3D scenes with Gemini and Three.js! 💥 g.co/gemini/share/2…

Check out my new game demo made using Three.js and Blender 🔶 —live now! bandinopla.github.io/pip-skull-demo #gamedev #solodev #argentina #indiegame

🕹️ Fiddling around with a new character controller for the Three.js/GameDev course. Big thanks to Quaternius for the amazing model and animation library—putting them to good use! 🔔 Want to be notified? Sign up here 👉simondev.teachable.com/p/games-three-…

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

It's egg hunt time! 🥚🧺 And I have 3 surprises for you. A new devlog 👉 youtu.be/O8LUJicF7v4 An alpha version of my portfolio 👉 threejs-journey.com/apps/easter-20… And a 30% discount code for Three.js Journey 👉 threejs-journey.com/join/easter2025

🕹️ Preparing a brand new BVH-based character controller which is lightweight, flexible, and requires no physics engine. 🍻 Big thanks to Garrett Johnson 🦋 for his incredible three-mesh-bvh library that made all this possible. #threejs #threejsJourney #webdev #gamedev #r3f #ecctrl

🧵 TSL is looking pretty awesome, but I got you covered until then. I just hit publish on ~2 hours of new content to the course, covering how to dig into Three.js's internals, and we cap the project off with some terrain with erosion and scattering tricks. 🎓It's live in the

I'm back to working on my water simulator for interactive experiences using #threejs + #r3f. This time, I'm experimenting with #WebGPU and #TSL for better performance. I'm loving it more and more by the minute. The link and potentially a tutorial will be available soon. But if

my new portfolio website is now online! i fell in love with mechanical worlds, turning like music box so i built one to tell my story 🎫 bilal.show you scroll to turn the cylinder and explore my world 🎠 #threejs #b3d #blender #threejsjourney

🕹️#BVHEcctrl now supports static, kinematic, and instanced static colliders! Instanced meshes share one BVH collider, minimizing performance impact. In testing, instanced colliders performed very similarly to regular instanced meshes. #threejs #threejsJourney #webdev #r3f #ecctrl

Well… just a minor update on handling instanced colliders. Try to squeeze out a bit more performance 🫠 #threejs #threejsJourney #webdev #gamedev #r3f #ecctrl #bvhecctrl

I finally have a lab 🧪 Making this infinite 3D scroll wasn't easy, but I'm happy.

SPWI global illumination in 3D with Radiance Cascades and Garrett Johnson 🦋's three-mesh-bvh. Probes are placed in screen-space and trace world-space intervals into a BVH. Resolves offscreen emitters and occluders; memory use tied to screen. Zero-shot, no noise, and fixed cost.
