Build your games and visualizations the brometal.dev way. All of the rendering and physics on the GPU. Everything compiled at build time. Ultra light runtime. All TypeScript. No boot-up time. First frame hits instantly. Don't make your AI coding agents build all of this from scratch - save time and tokens. brometal.dev/examples/ball-…

For years, I've been building graphics libraries, game engines, data visualization engines, physics engines, and even wrote a book about graphics. From all of my learnings, I've been cooking up a pet open source project that I believe to be the best web graphics library ever created, designed for the AI coding era. All TypeScript. All of the heavy lifting is done at compile time, including shaders and physics engines. Insanely thin runtime (~7KB runtime compared to Three.js's 336KB runtime, a 50x reduction). No scene graph required. Stunning graphics that run insanely smooth. Zero boot up time. Supports both WebGL2 and WebGPU. What will you create? brometal.dev

New "Bro Craft" demo built on BroMetal running entirely on the GPU. Shaders built in TypeScript. A single plane geometry with block elevations, stacking, material logic, all in the shaders compiled at build time, with an ultra thin runtime. brometal.dev/examples/brocr…

Opus 5 High might be the most ridiculous model I’ve ever tested. It produced this result in around ONE HOUR. Fable 5 needed almost 3 hours. GPT-5.6 Sol worked for over an hour and still created almost nothing compared to this. Opus 5 didn’t just win. It completely OUTCLASSED them.

@Jaenam97 Are you using a graphics library or just raw shaders?

Got it. Be sure to check out the examples for some inspiration, I'm working on adding more and more higher fidelity examples. brometal.dev/examples BroMetal essentially acts as guard rails for your AI coding agent, and forces most of the compilation to be done at build time (thus super thin runtime) and heavily incentivizes as much as possible to be pushed to the GPU via shaders, including rendering and math. So you can just prompt whatever it is you're trying to build, and your AI coding agent will build the app the "BroMetal" way, so it will have max performance.

NVIDIA did it again.. they trained a GPT that generates human movement instead of text.. next-token prediction, but the tokens are body motions. it's called GPC and it hit a 99.98% success rate reproducing a massive corpus of motion clips.. cartwheels, vaults, flips, all of it. → 99.98% success rate reproducing motion clips → learns cartwheels, flips, vaulting from raw data → adapts to new tasks with <1% extra parameters studios spend 6-12 months and millions of dollars building custom controllers for one character in one game. GPC does it in one forward pass. Pixar, Ubisoft, and every mocap studio on the planet just felt a chill down their spine. the same next-token trick that gave us ChatGPT is now doing parkour inside a physics engine.

img2threejs v1.3 is now available. 🎋 One photo → procedural Three.js code. No meshes. No manual modeling. GitHub: github.com/hoainho/img2th… v1.3 brings major improvements to geometry reconstruction, material generation, validation, and overall output quality. For this demo, I used the reference image of a CS2 ★ M9 Bayonet | Doppler Phase 3: tradeit.gg/csgo/trade?sea… If you’re new to img2threejs, now is a great time to try it. If you’ve used it before, I’d love for you to compare the results with previous versions. Feedback, bug reports, and PRs are always welcome.
