Google shows Gemini 4 Argon coding a real time 3D fur engine that runs in the browser
Studio-grade 3D fur dynamics, running live in your browser with Gemini 4 Argon. In @Antigravity, Argon coded a custom WebGL2 fur engine with automatic lightweight fallback — using GPU groom shaders, procedural character meshes, and animations for interactive, real-time hair physics.
Context
Demos like this show how far AI coding agents can go on graphics work that usually needs specialists, though it is a curated example.
This is a promotional demo from Google's main account. Gemini 4 Argon is Google's latest model, and Antigravity is Google's agent based coding tool, used in an earlier deck demo of a 3D Wizard Chess game.
Deep dive
On October 20, Google posted what it called studio grade 3D fur dynamics running live in the browser with Gemini 4 Argon.
Google said that in Antigravity, Argon coded a custom WebGL2 fur engine with an automatic lightweight fallback, using GPU groom shaders, procedural character meshes and animations for interactive, real time hair physics. WebGL2 is the standard that lets web pages draw 3D graphics with the device's graphics chip.
The video starts with a woman holding a small purple plush toy, then shows a rendered furry version of it in a browser. A settings panel offers presets and sliders for fur length, density, curl and clumping, and the character is shown against scenes named Studio, Cloud Sky and Cozy Desk, and placed on a real table through what appears to be the camera.
Google did not say how many prompts or how much human help went into the result, how long it took, or whether the code is available, so the demo shows what is possible rather than what a typical user would get. Studio grade is Google's own description. Fur and hair rendering is a demanding graphics task, and the demo is one of several Google has posted to promote Argon's coding.
What to expect next
Watch whether Google publishes the code or the prompts behind the fur engine, which would let developers judge how much Argon did on its own. Independent coding benchmarks and developer reports will show whether results like this are typical. Also watch for more Antigravity demos, as Google keeps using graphics showcases to promote Gemini 4 Argon against rival coding models.
