Seven days to build a single human eye. And the result looks surprisingly real.

Developer Gianluca Lomarco used Claude Code with Opus 5.5 to build this eye in Three.js.

No photos, no image textures, no pre-made 3D models. Just math, shaders, light simulation, and roughly 400 adjustable parameters.

The project took 161 code commits and 4,455 lines of GLSL.

What interests me most is how he got there. Creating realistic eyes involves countless adjustments to light refraction, iris patterns, reflections, and movement. Claude Code helped him work through those iterations, while he directed the visual result.

I think this approach has huge potential for indie game developers and digital artists.

Imagine building a realistic eye once, then generating hundreds of variations by changing parameters. Different iris patterns, colors, pupil sizes, and lighting responses, all controlled through code.

And there's a bigger possibility here: AI coding tools could make sophisticated procedural graphics accessible to individual developers who previously couldn't afford the time or specialized expertise.

I'm particularly curious about performance. Could this approach eventually handle dozens of animated characters in a game, even on mobile hardware?

That would be worth testing.
