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

✨ I added actual collision maps to as Javi Lopez ⛩️ kept telling me to do at our weekly coworking day today This means now the drone can not fly through buildings but it can fly through holes inside buildings like windows etc. Buildings are important because you can take cover there, bullets also hit the collision maps At the end of the video to show it worked I flew the drone a bit too hard into the wall so it died 😂 The tech behind it is Mesh BVH, so cool!!! "Mesh BVH is a THREE.js addon that builds a Bounding Volume Hierarchy from a mesh's triangles. A BVH is a tree where each node holds a box containing some triangles; child nodes split those triangles into smaller boxes. Queries walk the tree and skip entire branches that can't possibly contain the answer, turning "check all 5,000 triangles" into "check ~log₂(5000) ≈ 12 boxes."

you can just make a drone in threejs and have it fly around map imagery and put a camera on the drone and pipe its feed to a python vision model inference server for detections

if you make the brush stroke instances a subdivided plane and realize them you can transfer the normal from the base mesh and blend it with the plane normal to get more definition

10,000 rigidbodies at 15-60FPS in Three.js (faster than Unity/Godot). How? Babylon.js's new physics system: havok - it works w/ any frontend, so below is a video of Babylon's havok powering physics in a three scene. Kudos to the whole Babylon team! #threejs #webgl #babylonjs

A lot of Cole fans don’t understand how a nigga can just say “Bing Bop Boom BoomBoom Bop bam” and it work so effectively It ain’t deep its just stylin’ Snoop, JID, Biggie, Gibbs Some rappers can just style you to DEATH and get away with all the forbiddens Definitely a talent

Gemini Omni is changing video creation and most people still don't know what it can actually do. Here are 7 things you can do with it right now: 1. Image to Video in multiple styles: Upload a photo. describe the style. Gemini Omni turns it into a video. cinematic, anime, realistic. 2. Reimagine camera angles: Take any image and visualize it from a completely different angle. no reshooting. just describe it. 3. Change backgrounds: Swap the background of any video through plain conversation. no green screen. no editing software. 4. Change hairstyle: Describe a new hairstyle. Gemini Omni applies it. characters stay consistent across every frame. 5. visualize with moodboards: feed it a moodboard, audio, and a brief. it builds the video around the full creative reference — not just a text prompt. 6. swap characters and objects mid-scene: replace people, props, and objects in an existing video. the scene stays consistent. the physics hold up. 7. edit physics: describe how you want things to move. Gemini Omni adjusts the physics of the scene through conversation.

I've made some changes to the mesh top I'm trying to make. Bump maps have a lot of limitations and are quite difficult to work with but hopefully this is at least adequate enough. #TheSims4 #TS4 #ShowUsYourSims

Edit your own videos with Gemini Omni with just a conversation. 🎥 Prompt the changes you want to see to reimagine the action, change the point of view, or adjust the lighting over multiple turns. Every instruction builds on the last, so your characters stay consistent, the physics holds up and the scene remembers what came before. #GoogleIO

SOMEONE BUILT A WAY TO SEND FILES BETWEEN TWO PHONES WITH NO WIFI, NO BLUETOOTH AND NO NETWORK AT ALL it works with just a screen flashing qr codes at a camera one device plays an endless stream of animated qr codes, the other one points its camera at the screen and rebuilds the file out of the light no pairing, no app, no shared network, nothing but the camera > its pulling about 129 kb/s, a full 2mb image transfers in seconds > theres no back channel, the receiver can never ask for a missed frame, so it uses fountain codes, every frame is a scrambled mix of the file rather than one piece of it > that means the receiver just collects any frames it can catch in any order, and once it has enough it can reconstruct the whole file > dropping frames costs you a little time but never breaks the transfer > you can point the camera at a stream thats already running and it just locks on mid flight he was building a cached mp3 player because he was sick of ads and bad streaming quality. he wanted a way to send tracks phone to phone without both phones being on the same network, and realized flashing qr codes could carry the data he built the whole working prototype in one night with claude code its open source and already at 375 stars

3DGS render blender add-on v3.0 ( was just open-sourced! With KIRI tools, you can use "3DGS to mesh" function to get a mesh from Gaussian splatting, and now you can convert the mesh back to Gaussian splatting. It's kind of ironic, but we just try to bring handy tools to everyone. #GaussianSplatting #Blender

#gamedev when I made it so that a properly timed parry will interrupt all in front of you, and not just the attacker, it made things feel better (WIP obviously) not every enemy can be staggered from a single parry, but weak/basic ones can

Just found a tool every filmmaker needs to see. Retake in LTX lets you rewrite a scene without reshooting it. The lighting, camera movement, and the actor’s face stay exactly the same. You can change the dialogue, emotion, or expression and instantly get a new scene with new meaning, no new shoot. Here’s how it works:

Ok so... Anyone wanna learn how to do this? I might just do a quick writeup guide, but maybe make a video. Its like... REALLY easy and works with any hair that has highlights. Thoughts?

🚨 BREAKING: Scientists just figured out how to store sunlight… inside a molecule. Not a battery. Not electricity. The actual energy of the sun locked into chemical bonds. Read that again. Sunlight hits → molecule changes shape Energy gets trapped inside its structure Stays stored… until you release it as heat No wires. No grid. No battery. Just… stored sunlight. This changes how we think about energy: We don’t have to convert it anymore. We can store it directly as structure. Now think bigger: If energy can be stored in shape… What else in physics is really just structure holding energy? Mass? Stability? Even matter itself? So the real question is Are we discovering new tech… or finally understanding what energy really is? Follow me this is where physics gets interesting.

🚨 BREAKING What if mass… isn’t a fixed property? Scientists just found evidence that mass can change. Not in theory. Inside real matter. They detected a rare state called an η′-mesic nucleus where a particle gets trapped inside a nucleus… and its mass shifts. Let that sink in. Same particle. Same physics. Different environment… different mass. That means: Mass isn’t just “what something is.” It’s how it interacts with the vacuum around it. And the vacuum? It’s not empty. It’s a hidden structure that gives particles their properties. Mass may come from the vacuum The vacuum changes in dense matter So mass itself can change This is huge. Because it flips the idea that mass is fundamental. Instead: mass might be emergent. In my view: Mass isn’t a property… it’s a response to time/field structure. Change the structure… you change the mass. So the real question is: Are particles “things”… or just stable patterns in a deeper field? Follow me physics isn’t discovering matter… it’s discovering what creates it.

✨ Made a new mini feature on Photo AI: [ Grab from 3d model ] So the problem is we're at that stage in time (typical for AI) where image-to-3d models are not good enough but are fun to play with, but we know they'll be good enough in 1-2 years With [ Make 3d model ] you already can turn any Photo AI pic into a 3d model but it still looks hyper clunky and deformed, but it works! One cool idea I had to make that more useful and made now: Let people make a 3d model then change the view of the it with the 3d viewer, then press [ o ] and it grabs a frame of the 3d That image you can then [ Remix ] (img2img), and it becomes a real photo again and that in turn you can then turn into a video again with [ Make video ] So that essentially gives you a fully freeform camera position control to take photos with One thing I need to fix is the background/skybox, I kinda need to take the original photo and remove the person and just get the background for the 3d model viewer, in this case it should be white, but it's a start!

Hollywood used to spend years and millions to bring a single scene to life. Now, one bold idea becomes a 1-minute 8K scene. Then another — with the same characters and settings. Before you know it, you’re creating full episodes, not just “content.
