the gold accents work really well here bro. just enough color to guide the eye without making the page feel busy
A watch movement lifted from one photograph into 3D. HEXANOX is an independent horology institute. We certify mechanical movements by measurement, amplitude, beat error, positional variance, to tolerances your eye cannot see.
I built this project to test A watch movement lifted from one photograph into 3D. HEXANOX is an independent horology institute. We certify mechanical movements by measurement, amplitude, beat error, positional variance, to tolerances your eye cannot see. The core engineering challenge was sustaining uncompromised 60 FPS rendering using Three.js (GLB 3D) while handling continuous user interaction without framework overhead.
WHAT I WAS TESTING:
I focused on two core engineering benchmarks:
Precision implementation of image → GLB under continuous interactive user input
Sustained 60 FPS render performance and zero-dependency browser execution
THE TECHNICAL SIDE:
Engineered directly in the browser with Three.js (GLB 3D), WebGL / GLSL Shaders, Canvas2D, Image → GLB. The application runs without third-party frameworks or build-step dependencies, using hardware-accelerated rendering and custom event loops to achieve zero-latency response.
Everything executes in the browser using Three.js (GLB 3D), WebGL / GLSL Shaders, Canvas2D, Image → GLB. No third-party frameworks, no heavy runtime bundles, and zero external tracking.
WHAT I LEARNED:
Balancing the mathematical rigors of image → GLB with tactile browser interaction required tuning event throttling and memory allocation to eliminate all garbage collection stutters.
Finding the sweet spot between mathematical precision and frame budget took careful profiling, but the result runs at a steady 60 FPS even on modest hardware.
TRY IT YOURSELF:
The live build is deployed on Netlify. Open it in your browser, test the controls, and observe the render response times.
