One video prompt: Gemini recreates interactive three.js lens lab in 45 minutes
fofrAI · x · 2026-10-17
Developer thtbee fed a demo video to Gemini 4 Argon and asked it to build something similar — it nailed a fully interactive "Plane of Focus" camera lens lab in three.js, live and playable, in just 45 minutes total.
The demo visualizes photography optics: focus plane, circle of confusion, aperture from f/2 to f/16, exploded lens view, keyboard controls and free-roam camera. Another striking showcase of video-to-app generation.
